How do i use void with methods in Java?

public String firstMethod() {
    System.out.println("Hello!");
    return 'Done!';
}

and

public void secondMethod() {
    System.out.println("Hello!");
    return 'Done!';
}

Please, don't tell me "Void returns a value". Where does it return, how, and why do i need to use this? How can it be benefit from using?

Export Function in Display Tag

I am working on one migration project(Struts --> Spring MVC) but without changing the UI parts. The place where I stuck is my table using Display Tag. I am using Display tag to show data in tabular format like below.

<display:table style="width:100%" name="sessionScope.list" id="listID" export="true" sort="list" pagesize="20" defaultorder="ascending">
    <display:column property="rowNumber" title="#"/>
    <display:column property="issuerName" title="Issuer Name" sortable="true" paramId="in" paramProperty="issuerName" />
    <display:column property="contractNumber" title="Contract Number" sortable="true"/>
    <display:column property="ip" title="IP" sortable="true"/>
    <display:column property="maturityDate" title="Maturity Date" sortable="true"/>
</display:table>

As we know marking export="true" gives us "Export options" with options like CSV, Excel, XML.

My problem is, the link that is generated on each options is like below

http://localhost:8080/myWebApp/WEB-INF/pages/myjsp.jsp?d-445967-e=1&6578706f7274=1

As you can notice, its like jsps path which is inside WEB-INF folder. That can not be accessed from outside. But in my old application this link appears as below.

http://server:port/myAppName/myJspName.jsp?d-445967-e=3&6578706f7274=1

Since this was an Struts application so folder struct was little different where we had JSPs outside

WEB-INF folder.

Same issue I am facing with pagination links.

Thanks

Hibernate JPA Joined Inheritance

I have a project with a part of the data structure made with @Inheritance(strategy = InheritanceType.JOINED). That part of the data structure looks something like this:

The design is based on the thoughts in this article. I'm using Hibernate with JPA2 interface as my datalayer. The structure above has resulted in the following pojo/dao classes (getters and setter omitted):

BaseItem:

@Entity
@Table( name = "base_item" )
@Inheritance(strategy = InheritanceType.JOINED)
public class BaseItemPojo {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;
}

PhysicalItem:

@Entity
@Table( name = "physical_item" )
public class PhysicalItemPojo extends BaseItemPojo{
}

SomeHardware:

@Entity
@Table( name = "some_hardware" )
public class SomeHardwarePojo extends PhysicalItemPojo{
}

SomeOtherHardware:

@Entity
@Table( name = "some_other_hardware" )
public class SomeOtherHardwarePojo extends PhysicalItemPojo{
}

Here is my issue:

One of my other tables has a reference to the base_item class, and it would make my life a lot easier, if that class loaded either the "some_hardware" or the "some_other_hardware" based on that base_item_id. Hence, I made navigation properties like this on that particular class:

@Entity
@Table( name = "some_navigation_class" )
public class SomeNavigationClassPojo{
    @ManyToOne(optional = false)
    @JoinColumn(name="base_item_id", insertable = false, updatable = false)
    private BaseItemPojo baseItem;

    @ManyToOne
    @JoinColumn(name="base_item_id", insertable = false, updatable = false)
    private PhysicalItemPojo physicalItem;

    @ManyToOne()
    @JoinColumn(name = "base_item_id", insertable = false, updatable = false)
    private SomeHardwarePojo someHardwarePojo;

    @ManyToOne()
    @JoinColumn(name = "base_item_id", insertable = false, updatable = false)
    private SomeOtherHardwarePojo someOtherHardwarePojo;
}

As you might have guessed, the above didn't work. If I try to access a "SomeNavigationClassPojo" that has a related "SomeHardwarePojo" attached to the entity, I get the following error:

java.lang.IllegalArgumentException: Can not set SomeOtherHardwarePojo field SomeNavigationClass.someOtherHardware to SomeHardwarePojo.

For reference, my goal is that if either someHardwarePojo or someOtherHardwarePojo doesn't exist in the database, they should just be set to null, and not tried to be mapped to respective other child of PhysicalItemPojo

Deployed JavaFX Application with embedded JRE not startable on some systems

The Application gets deployed via Java FX Packaging Tools and is bundled with the JRE (8u40, 32bit). The resulting Ant File was extended by us to run unit-tests and stuff like that. Since we want to support custom locations, we don´t use the generated FX-Installer. So the generated bundles/[appname] folder gets zipped and extracted on the target systems. Usually the application runs fine, but on some systems we experience a weird issue.

When the user tries to start the application via generated .exe file, the application does not start. Nothing happens, no runtime errors, no system errors, just nothing at all. The same happens, when I try to start the .jar directly. Unfortunatly the clients have no rights to use the terminal, so I can´t launch the application from there.

The system, where this behavior occurs is Windows 7. For debugging purposes I added a simple Swing frame before starting the application, but this one isn`t starting either. No log-files where created, so I guess the application does not start at all.

Does anyone know if there is any chance to find out, what is going wrong during the start of the application and/or the runtime enviroment?

LDAP Sub Query to fetch SamAccountName from CN

Currently I have this query as mentioned below which returns all users but each user has a parameter called manager which returns "CN=Peder Ellingsen,OU=Users,OU=NO,OU=Countries,DC=xds,DC=xxx,DC=com"

Need the samAccountName instead of the CN above ,need help with LDAP Subquery which can help me to get the SamAccountName directly by modifying the query mentioned below

Wanted to avoid double hits to ldap server just to get the SamAccountName.

(&(objectCategory=person)(objectClass=user)(memberof=cn=MyCompass_NO,OU=Groups,OU=Common,OU=Applications,DC=xds,DC=xxx,DC=com))

I have a controller class as shown below.

@Controller
public class HomeController {

    @RequestMapping(value = "/home", method = RequestMethod.GET)
    public String callHomePage() {
        return "home";
    }

    @POST
    @Consumes({MediaType.APPLICATION_XML})
    @RequestMapping(value = "/postHome")
    public ModelAndView postHomeList(@ModelAttribute("jsonString") HomeRequest request, @Context HttpServletRequest servletReq, @Context HttpServletResponse servletRes) {
        ModelAndView mav = null;
        System.out.println(request.getHomeId());
        return mav;
    }

}

In this home.jsp a textarea field is there where I can enter some values ( json string ). After submission the value for request.getHomeId() is coming as null. Can any one help me to solve this issue?

How to format time from Android's TimePicker?

Hi I am currently using a TimePickerDialog to set the time and display it into a text view. However, I am having problems with the formating. This is my code

    TimePickerDialog.OnTimeSetListener time = new TimePickerDialog.OnTimeSetListener() {
    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        if ((hourOfDay >= 1) && (hourOfDay <= 11.59)) {
            hours = hourOfDay;
            am_pm = "AM";
        } else if (hourOfDay >= 12) {
            hours = hourOfDay - 12;
            am_pm = "PM";
        } else if (hourOfDay == 0) {
            hours = 12;
            am_pm = "AM";
        }

        tvScheduleTime.setText(hours + " : " + minute + " " + am_pm);

    }
};

This method works in retrieving AM and PM but the numbering is weird, like 6:08 AM becomes 6:8 AM. How can I make it so that it creates the text HH-MM AM/PM?

ParameterizedAssertionError in JUnit Theory

The following test throws a ParameterizedAssertionError. It seems that both parameters of the test method get the same argument, although they are of different types.

import java.lang.reflect.Field;
import java.util.ResourceBundle;

import org.junit.experimental.theories.DataPoint;
import org.junit.experimental.theories.DataPoints;
import org.junit.experimental.theories.Theories;
import org.junit.experimental.theories.Theory;
import org.junit.runner.RunWith;

@RunWith(Theories.class)
    public class ErrorIDsTest {

    @DataPoints
    public static Field[] errorIDs() {
        return ErrorIDs.class.getDeclaredFields();
    }

    @DataPoint
    public static ResourceBundle bundle = null;

    @Theory
    public void testThatFails(Field field, ResourceBundle bundle) throws Exception {
    }

    interface ErrorIDs {
      public final String Fehler = "ErrorIDs.Fehler";
    }
}

The exception is ParameterizedAssertionError

org.junit.experimental.theories.internal.ParameterizedAssertionError: testThatFails(errorIDs[0], errorIDs[0]) at org.junit.experimental.theories.Theories$TheoryAnchor.reportParameterizedError(Theories.java:183) at org.junit.experimental.theories.Theories$TheoryAnchor$1$1.evaluate(Theories.java:138) ...

I used an example from here ParameterizedAssertionError in Theory but facing exactly the same. It's fixed but I'm not using the same .jar. Is there any other fix to resolve this?

Firebase returning keys of child node in different orders on different devices/Android versions

I am getting a snapspot of the data from my Firebase database to retrieve a users list, but the order of the keys being returned is different depending on the Android version/ device being used.

For demonstrative purposes I have shortened the method, but it is essentially as follows:

public void getUsers(){

Firebase ref = new Firebase("http://ift.tt/1eQ0zaI");

    final Firebase userRef = ref.child("users");

    userRef.addListenerForSingleValueEvent(new ValueEventListener() {

        @Override
        public void onDataChange(DataSnapshot snapshot) {


           snapshot.toString();

                                                           }                                                           
                                                                  });
                           }

It is the data I get from calling toString() on the snapshot object (snapshot.toString()) that changes order.

I have tried it on 4 devices. The 2 running Lollipop (Nexus 7 5.1.1 & Galaxy s4 5.01) return the data in the same order. And the 2 two other devices (HTC Sensation 4.0.3 and Motorola G2 4.4.4) return the data in the same order (but a different order to devices with Lollipop).

There is no difference in the code used, and the data in the database was completely unchanged at the times when I retrieved the snapshots.

Here is the data order on the 4.4.4 and 4.0.3 devices:

DataSnapshot { key = users, value = { 114585619420240714499={userIDOfCUser=114585619420240714499, NameOfCUser=testName, EmailOfCUser=testerfireapp@gmail.com, friends={103902248954972338254={userIDOfFriend=103902248954972338254, NameOfFriend=testName2 }}}

Here is the data order on the 5.1.1 and 5.01 devices:

DataSnapshot { key = users, value = {114585619420240714499={NameOfCUser=testName, userIDOfCUser=114585619420240714499, friends={103902248954972338254={NameOfFriend=testName2 , userIDOfFriend=103902248954972338254}}, EmailOfCUser= testerfireapp@gmail.com}}}

Why is the data being delivered in different orders depending on the android version/device being used? is there another difference I am unaware of ?

Thanks in advance.

How can I animate my binary tree drawing in Java

I am really struggling with a a project that I am working on. The eventual outcome should be an animation that shows algorithms in AVLTrees. I have managed to display a tree using values input by a user. But I am worried that they I have done it may prevent me being able to animate it. Each time a node is added, the entire tree is re drawn (up to a depth of four at the moment), is there a way (I assume after a lot of "if" statements) do gradually animate the new line added, and then have the new node appear? I apologise in advance if this is the worst code ever seen on here, I"m very new to java and struggling a lot!

This next class is where the drawing takes place. So I assume this is where I put the timer??? Beyond that, I have no idea what I'm doing but feel I have read everything on the internet :/

Why Heap sort is not considered as a stable sorting alogorithm

In Java Heap sort seems a best sorting algorithm while sorting an array of random numbers according to http://ift.tt/qTnDd2 But still I read that Heap sort is not stable, why so? Which sorting algorithm should be considered best algorithm while sorting an array or random numbers?

Java mail don't return subject

I'm using javamail to rescue mails of inbox. I get all mails from inbox, but the subject(message.getSubject()) return null.

I research in several sites and all proposed solutions not work.

This problem occurs only in the Tomcat6, if a execute even code in java project for main method i get all atributis, include subject. I'm user de SSL protocol (pop3s).

Thanks for help

public void getMails(final String host, final int port, final String user, final String password){

   final Session session = Session.getInstance(System.getProperties(), null);
   final Store store = session.getStore("pop3s");   

   store.connect(host, port, user, password);
   Folder inbox = store.getFolder("INBOX");
   inbox.open(Folder.READ_WRITE);
   int count = inbox.getMessageCount();
   System.out.println(" Count Emails "+count);

   final Message[] messages = inbox.getMessages();                
   for (final Message message : messages) { 
       //This return null
       System.out.print("mail subject: " + message.getSubject() + " send at: " + message.getSentDate());
       //This return body of mail
       System.out.print("mail subject: " + message.getContent().toString());
}

When i try to print it, I have

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid :

But only if column width on UI less than some value (less, not greater). Frame paddings = 0. I also trying to set x="0" - it doesn't help. In jasper src it fails here:

if (element.getX() + element.getWidth() > avlblWidth)
where int avlblWidth = frame.getWidth() - leftPadding - rightPadding;
element form frame.getElements();

I would be grateful for any help

Please let me know what is an issue. After upgrading only , I am facing this isssue, could you please guide me about this.

In Spring can you give an example where isolation level is used along with propagation?

I want to perform isolation level along with propagation How I can achieve it. Suppose inside RequiresNew I want to do READ_COMMITTED in DB.

Is Declaring @Transactional(propagation = Propagation.REQUIRED,isolation=Isolation.READ_COMMITTED) valid?

If yes,How it will internally work?

Creating only @Transactional(isolation=Isolation.READ_COMMITTED) will create a new transaction? If yes, will it be a new transaction every time behaving like RequiresNew?

I have multiple select and join SQL queries and I want to return a single result set in MySQL

SELECT COUNT(*) FROM SYSTEM.PARTITIONEDTABLES where schema=? and TABLENAME=?

SELECT PC.SCHEMA, PC.TABLENAME, PC.PARTITIONNAME, PC.ISDEFAULT, PC.VALUE,PT.PARTITIONTYPE, PT.PARTITIONINGCOLUMN, PT.DEFAULTPARTITION, PI.STORAGEGROUP FROM SYSTEM.PARTITIONCRITERIA PC JOIN SYSTEM.PARTITIONEDTABLES PT ON PC.TABLENAME=PT.TABLENAME AND PC.SCHEMA=PT.SCHEMA JOIN SYSTEM.PARTITIONIDS PI ON PC.TABLENAME=PI.TABLENAME AND PC.SCHEMA=PI.SCHEMA AND PC.PARTITIONNAME=PI.PARTITIONNAME WHERE PC.SCHEMA='' AND PT.TABLENAME=''

What are the telegram-api AbsApiState contracts (How should I implement it's methods?)

I am trying to write a telegram client with ex3ndr/telegram-api, but I don't know how to implement that correctly. Anybody knows how these methods are supposed to work ?

Aspectj default constructor pointcut

Im working with some AspectJ code and i want to catch all the executions for none private pointcuts.

@Pointcut("execution(public * *(..))")//Public
public void publicMethod(){};
@Pointcut("execution(protected * *(..))"//Protected
public void protectedMethod(){}

@Pointcut("@annotation(mypackage.name.annotationName")
public void annotationPointcut(){}

@Around("annotationPointcut() && (protectedMethod() || publicMethod())")
public Object test(){ System.out.println("Should not print private"); }

I read about using ! (not) but could not get it to work. Something like

@Pointcut("!execution(private * *(..))"

But without getting it to work.

I could not find a modifier name for default class modifier in the aspectJ, have I missed it or do i need to try and solve it by using ! not sign in some sort of way?

Regards a new dev that are learning aspectJ

here you can see the file testServiceContext.xml:

 <!-- Scan for services -->    
    <context:component-scan base-package="com.devices.services.impl" />
    <context:component-scan base-package="com.devices.services.geolocation" />

and the class seems to be well declared

package com.devices.services.geolocation

@Service(value = "geolocationService")
public interface GeolocationService {
....    
}

Trying to upload aa file to Google Nearline Storage from a Java program using the Java API, but I'm getting a Forbidden error

This is my code:

        File file = new File("text.txt");

        InputStream inputStream = new FileInputStream(file);  // object data, e.g., FileInputStream


        long byteCount = inputStream.available();  // size of input stream

        InputStreamContent mediaContent = new InputStreamContent("application/octet-stream", inputStream);
        // Knowing the stream length allows server-side optimization, and client-side progress
        // reporting with a MediaHttpUploaderProgressListener.
        mediaContent.setLength(byteCount);

        StorageObject objectMetadata = null;

        Storage.Objects.Insert insertObject = client.objects().insert("mybucket", objectMetadata, 
           mediaContent);
        insertObject.setName("text");

And this is the error message:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
  "code" : 403,
  "errors" : [ {
    "domain" : "global",

    at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:460)
    at StorageSample.main(StorageSample.java:194)
And I have "isOwner" as my permission.

According to: http://ift.tt/1MJA59N

The error is because "The requested operation is forbidden and cannot be completed."

So how can I overcome this and upload the file using a Java program.

Thanks in advance.

Why has ArrayList add E and remove Object [duplicate]

This question already has an answer here:

• Why aren't Java Collections remove methods generic? 8 answers

For ArrayList we have:

public boolean add(E e) {

but for remove we have:

public boolean remove(Object o) {

Why isn't it?:

public boolean remove(E e) {

how to handle this error "java.lang.NoSuchFieldError: INSTANCE" in EXCELSIOR JET?

When I run my project in eclipse it works fine but when I want to make an exe of it via EXCELSIOR JET it gives this error!: I read some links but most of them where in a format like:

java.lang.NoSuchFieldError: INSTANCE at org.apache.http.impl.io.DefaultHttpRequestWriterFactory

I mean INSTANCE is referring to apache http or something and that was because some jar files make conflict, but the error my project gives, is referring to one of my Project and I don't know what is wrong.
