J2SE 5.0 Source code

Could someone please tell me when it's the source code for J2SE 5.0 going to be available under the Sun Community Source Licensing page: http://wwws.sun.com/software/communitysource/j2se/java2/download.html?
Thanks

I was going to say the same thing. It is a FCS release: First Customer Shipment.
I am looking for the jvm source code and other things. src.zip contains almost all the JAVA runtime source code (java source code), however there are some reference implementations whose source code is not in src.zip (for instance the RI for jcp 114: http://www.jcp.org/en/jsr/detail?id=114 ).

J2SE 5.0 JDK Source Code setup

I downloaded the J2SE 5.0 JDK Source Code .zip files, but how do I set it up? I'm running Windows XP.

unzip the file to whatever location you want e.g. C:\JavaApiDocs
which will create C:\JavaApiDocs\docs
double-click C:\JavaApiDocs\docs\api\index.html to see if all is well
if so, put a shortcut to index.html on your desktop
many ide's have a link to the docs, for searching etc - go to your ide's options
and point the docs location to C:\JavaApiDocs

Unable to depoly Web Serivce for the source code written in other editors

Hi all,
I am planning to implement webservice with the following code. But I am facing few problems with this can some body help me with this.
The code looks like this AND IS NOT WRITTEN IN Jdeveloper BUT EDITPLUS
package package1;
public class Sum
public int getSum(int a, int b)
          return a+b;
package package2;
public class Sub
public int getSub(int a, int b)
          return a-b;
package package3;
import package1.*;
import package2.*;
public class Mul implements TestInterface
     Sum sm = new Sum();
     Sub sb = new Sub();
public int getMul(int a, int b)
          return sm.getSum(a,b)*sb.getSub(a,b);
public static void main(String [] args)
          Mul ml = new Mul();
          System.out.println(âThe result of (3+6)*(3-6) is â+ ml.getMul(3,6));
package package3;
interface TestInterface extends java.rmi.Remote;
     public int getMul(int a, int b) throws java.rmi.RemoteException;
I have written this in editplus. Not in Jdeveloper.
Now I want publish getMul() as web service using Jdeveloper.
I have created a new application work space. And from File-->New
I have choose project from existing source and imported âpackage3â.
At this stage it was unable to find the class files Sum and Sub so I placed Sum.class and Sub.class in Appliction1-Project1-classes-
Now the Mul class did not have any errors and it compiled fine. When run it gave the correct output.
Using the web service wizard I was able to generate wsdl file , deployment descriptors etc.
The problem I was facing was form this stage when I am trying to deploy it on to a standalone oc4j server it is not able generate the WebServices.war file and hence is not deployed on to the server.
With the same code written in Jdeveloper everything is working fine.
My doubts are
1)     why is it not able to generate WebService.war file?
2)     It is giving some ClassNotFound exception during the deployment. But when compiled and run its giving the correct output.
3)     Even when everything was written from within the Jdevelper it did not include Sum.calss and Sub.class in WebSevice.war. Is there any way we could mention during its (WebService.war) generation , the class files to be Included.
The other issue is how to add an existing source code to already existing project. In my case Once I have imported package3 I also want to import package2 and package1 in different steps.
I thank in advance for helping me.

Can you tell us what you mean by correct type of project?
You can start with an empty project. Then, you have to create an "EAR file" deployment profile (New Gallery / General / Deployment Profiles).
So when I deploy a J2SE module onto oc4j server should I specify the class path? If so where ? How can I solve this problem?
Once you deploy your code into oc4j, it becomes a J2EE application. You don't need to deal with the classpath - just make sure that all the required code is included in your .war file. To do so, check the list of classes packaged under the deployement properties dialog.
Can you send me the links of few articles where I can learn more about these kind of stuff?
If you want to assemble applications without to use JDeveloper wizard, you have another option: using the WebServiceAssembler tool that is par of the oc4j bits will help you to do this from a command line promt, and will handle the J2EE packaging aspect for you.
See online documentation (10.1.2): http://download-west.oracle.com/docs/cd/B14099_04/web.htm
In the "Developer's Guide", chapter 9 is about "Web Services Tools"
For JDeveloper J2EE samples, you can start by looking at the OBE: http://www.oracle.com/technology/obe/obe_as_1012/j2ee/index.html
Hope this helps,
Eric

How to understand the Vector source code for function elements()?

hello all:
This following code snippet is extracted from java.util.Vector source code.
who can tell me how i can understand what the function nextElement does?
thank you
public Enumeration elements() {
     return new Enumeration() {
         int count = 0;
         public boolean hasMoreElements() {
          return count < this.num_elem;
         public Object nextElement() {
          synchronized (Vector.this) {   //???
              if (count < elementCount) {//???
               return elementData[count++];
          throw new NoSuchElementException("Vector Enumeration");
    }

Perhaps code would help more. This codeimport java.util.Vector;
import java.util.Enumeration;
import java.util.Iterator;
public class Test {
    public static void main(String[] arghs) {
     Vector v = new Vector();
     Integer two = new Integer(2);
     // Fill the Vector
     v.add("One");
     v.add(two);
     v.add(new StringBuffer("Three"));
     // Enumerate through the objects in the vector
     System.out.println("---- Enumeration ----");
     Enumeration e = v.elements();
     while (e.hasMoreElements()) System.out.println(e.nextElement());
     // Loop through the objects in the vector
     System.out.println("---- Loop ----");
     for (int i=0; i<v.size(); i++) System.out.println(v.get(i));
     // Iterate through the objects in the vector
     System.out.println("---- Iterator ----");
     Iterator i = v.iterator();
     while (i.hasNext()) System.out.println(i.next());
}produces this output
---- Enumeration ----
One
2
Three
---- Loop ----
One
2
Three
---- Iterator ----
One
2
Three
So, for a Vector, all three do the same thing. However, Iterator is part of the Collection Framework (see [url http://java.sun.com/j2se/1.4.2/docs/guide/collections/index.html]here). This allows you to treat a whole bunch of [url http://java.sun.com/j2se/1.4.2/docs/guide/collections/reference.html]objects which implement the Collection interface all the same way. I know this is way more than you were asking, but I hope it at least clears up what you were asking.

Instead of requested page source code is getting populated in WAS 6.1.0.15

Hi All,
I'm trying to bring up an application using jnlp.please find below the source code for the same.
When i deploy the application in WAS 6.1.0.0, i'm able to bring up the application without any issue.
But other than 6.1.0.0 if i deploy the same war file in any other WAS server, itz just showing the source code when i request for href in the browser.
Kindly some one help me to resolve this.

Type must be registered with jnlp extension so that content type is set (in the header with value application/x-java-jnlp-file), this should be done in httpd.conf (with an AddType), you can google for it or ask any server administrator for it, should be something like:
AddType .jnlp application/x-java-jnlp-fileMaybe you can give a look at working httpd.conf (on 6.1.0.0 searching for 'application/x-java-jnlp-file') and copy/paste in other configs.
Bye.

Finding the source code from Jar file

Hi,
I am a beginner java programmer but have been entrusted with learning our company's Java application. The architect of the application is not forthcoming in sharing information and so I need help in tracing the source code for the application. I know where the .jar files are stored but I don't know where the actual .java or .class files are stored.
In the .profile file, I see the classpaths set to various jar files. eg.
CLASSPATH=$PATH:/eaid01_apps/merc01/libs/tools/java/drivers/bin/eaiRun.jar
When I view this jar file with command "jar tf eaiRun.jar", it displays all the files under it. Onc such listing is as following:
citi/eai/EAI.class
citi/eai/Interface.class
I want to go to that specific directory on our file system which is storing these .class or.java file. From what I have learned about packages, I should find some folder called 'citi' ,'eai'.
However I am not able to find these folders anywhere on file system. Is there a way I can find where the actual souce code is by looking at the jar files.
Please help. Let me know if you need more information.
thanks,
Anand.

Is there a way I can find where the actual souce code is by looking at the jar files.No, in general you can't, you should ask the architect that you mentioned earlier. The name of the source file is sometimes stored in the .class file for debugging purposes but that's unlikely going to help you find the files.
You should also ask if he/she has got any documentation of the system. It's often a lot easier to follow documentation written in human language than program code written in a programming language. There could be documentation in a format similar to this: http://java.sun.com/j2se/1.4.2/docs/api/

Who can tell me which directory the JSSE source code in?

I get the source code of JDK5,but there are too many directories ,I don't get the source code of JSSE,I am beginner.

Then you have no need for the source code of either J2SE or JSSE actually.

Xletview: why not use sun's javaTV source code directly ?

xletview : one emulator for viewing MHP Xlets on a PC;
I see many difference from sun's code about the part of javaTV.
Why the author Martin Sveden need to rewrite them and not use sun's javaTV source code directly ?
Thank you for your any answer.
Sorry for my horrible english.

XleView is a fine effort, but it has its limitations. I tried using it for the GunBunny demo available in the JavaME SDK 3.0 Eary Access available in
http://java.sun.com/javame/downloads/sdk30ea.jsp
and I encountered some of thost limitations. What Sveden does it several tricky manipulations in a classloader for the Xlet. In particular, he translates bytecode as he loads the Xlet's classes, changing some class names, such as changing
java.awt.Toolkit
tto
xjava.awt.Toolkit
This works up to a point. This version of Toolkit usually just turns around calls java.awt.Toolkit's corresponding routine, but he deliberately he does not implement the ubiquitous
public Image createImage(URL url)
When I downloaded his source and tried adding ths into his code, I then encountered at runtime
Uncaught error fetching image:
java.lang.NullPointerException
at sun.awt.image.URLImageSource.getConnection(URLImageSource.java:97)
at sun.awt.image.URLImageSource.getDecoder(URLImageSource.java:107)
at sun.awt.image.InputStreamImageSource.doFetch(InputStreamImageSource.java:240)
at sun.awt.image.ImageFetcher.fetchloop(ImageFetcher.java:172)
at sun.awt.image.ImageFetcher.run(ImageFetcher.java:136)
I think that this is some optimization within J2SE where they do not wait for the image to load and do the fetching in a separate thread. I do not know if there is some way to force the Sun's JVM to disable this optimization and I have not investigated furher, but I did email Svenden. I noticed that the current version of XleTView is 0.3.6 which is dated June 2004 and the web site http://www.xletview.org/ has had not news since 2005 .
I note that Svenden provides an elegant user interface but I advise you not try to learn the API's from his classes: he makes no effort to keep his implementation separate from the API standards so, for instance, his version of HScene is
package org.havi.ui;
public class HScene extends Container
implements HComponentOrdering, ImageObserver, MenuContainer, Serializable {
whereas the real standard is
public class HScene extends Container
implements HComponentOrdering {
I hate to critize such a fine effort, but it is best to keep an imlementation separate from the public API.
I agree that having a lightweight, simple and Java feature-complete Xlet viewer running would be very helpful, especially if BD-J gains much popularity. I have found trying to work with the vendor players described at
http://wiki.java.net/bin/view/Mobileandembedded/Blu-RayDiscHelloWorld
to be frustrating. I tried all four mentioned and I have gotten none of them to work for me yet. These are huge downloads and the "Intro Version" of Arcsoft pointed to at the SDK 3.0 Early Access page
http://www.arcsoft.com/products/totalmediatheatre/
just gives a "File not found" HTML page. This forum post mentions that perhaps it was recently taken down?
http://www.arcsoft.com/forum/forum_posts.asp?TID=1084
I have already emailed Michael Downs of Arcsoft since he is mentioned here:
http://wiki.java.net/bin/view/Mobileandembedded/BDJPCPlayers
What did work for me was to take Sun's JavaTV 1.1 Reference Implementation and PowerDVD's BDJ.jar and hack/fix a few classes to get GunBunny to work within the RI's RunXlet program. This is not trivial but I will will describe:
Download the JavaME 3.0 SDK EA and then download the correct version of PowerDVD that the SDK page points to:
http://www.brothersoft.com/powerdvd-download-50794.html
Download the RI binary and source of Java TV API 1.1
http://java.sun.com/javame/technology/javatv/index.jsp
Since I am too lazy to use anything but the latest 1.6 JRE as a runtime, I have to fix
com.sun.tv.media.util.MediaThread
to comment out its stop() method. This is becase stop() was deprecated and made final in J2SE 1.5
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Thread.html#stop()
http://java.sun.com/j2se/1.5.0/docs/guide/misc/threadPrimitiveDeprecation.html
Next, I had to mae a change to Sun's JavaTV implementation to keep the GunBunny demo happy by providing a ServiceContext. The RunXlet program calls SIEmulator, but that environment does not provide a ServiceContex, so I added one back in:
com.sun.tv.receiver.SIEmulator
private static ServiceContext svcctx = null;
Add before every call to new AppSignalEvent() and add the svcctx as the second-to-last argument:
if(svcctx == null){ try { svcctx = new com.sun.tv.ServiceContextImpl(); }catch (Exception e){ e.printStackTrace(); } }
I then had to hack a few PowerDVD classes, which is evil of me. First, I had to build an empty class by the name of
sun.util.BDJPlugin
becuase some PowerDVD class extends it but it is not in its BDJ.jar and then I had to reverse-compile (evil!) and modify one of their internal classes to avoid a dependency on their native methods. What I ended up with was a hacked version of com.cl.bdj.helper.CUtil to avoid the native methods which access the registry where they query for registry settings but also provide a default value (which I return).
com.cl.bdj.helper.CUtil
private static String pGetRegistryString(long i ,String string ,String string3) {
return string3;
private static int pGetRegistryInt(long i ,String string ,int j) {
return j;
The last thing I had to do was to change com.hdccookbook.gunbunny.BaseXlet, to use the JavaTV container rather than the org.havi one:
import javax.tv.graphics.TVContainer;
import java.awt.Container;
change
// protected HScene scene;
protected Container scene;
public final void run() {
// waitForPresenting();
// scene = HSceneFactory.getInstance().getDefaultHScene();
scene = TVContainer.getRootContainer(xletContext);
In order to having working keys, I had to add the KeyListener interface to BaseXet and
run(){
addKeyListener(this);
and then add a near duplicate of the org.dvb.event.UserEvent* stuff that is already there:
public void keyPressed(KeyEvent e){
switch(e.getKeyCode()){
case KeyEvent.VK_0:
case KeyEvent.VK_1:
case KeyEvent.VK_2:
case KeyEvent.VK_3:
case KeyEvent.VK_4:
case KeyEvent.VK_5:
case KeyEvent.VK_6:
case KeyEvent.VK_7:
case KeyEvent.VK_8:
case KeyEvent.VK_9:
numberKeyPressed(e.getKeyCode() - KeyEvent.VK_0);
break;
case KeyEvent.VK_ENTER:
enterKeyPressed();
break;
case KeyEvent.VK_LEFT:
arrowLeftKeyPressed();
break;
case KeyEvent.VK_RIGHT:
arrowRightPressed();
break;
case KeyEvent.VK_UP:
arrowUpPressed();
break;
case KeyEvent.VK_DOWN:
arrowDownPressed();
break;
public void keyReleased(KeyEvent e){
// System.out.println("Released: e="+e+" code="+e.getKeyCode());
public void keyTyped(KeyEvent e) {
// System.out.println("Typed: e="+e+" code="+e.getKeyCode());
It then comes up and functions, but the rendering is not very good. Again, this is complete hack. Running the Java TV 1.1 RI in a JRE 1.6 is not supported. If you try to run any of the other examples, you will discover that the XML parsing is broken in JRE 1.6 with this message:
Parsing failed: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequence
Exception: Invalid byte 1 of 1-byte UTF-8 sequence., file: lib\JavaTVSampleFile01.xml
and you have to go and change the lines in
lib\JavaTV.properties
from
ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
# ServiceFileHandler=SampleData_01
to
# ServiceFileHandler=com.sun.tv.receiver.ReceiverFile
ServiceFileHandler=SampleData_01
and build samples\db\SampleData_01.java and put it in your classpath along with all these other hacks.
Nonetheless, if you want to develop a somewhat generic Xlet that uses some BD-J features, that is how you might do it. But the moment you exercise anything else in the vendor's BDJ.jar that simply doe snot work outside of their environment or invokes one of their native methods, you are again stuck.
It would be nice if Sun would at least bother to update the JavaTV RI with the fixes I hae mentioned. Their "jmflite" implementation does not render perfecly but at least it would give the programmer something to work with without having to deal with an older JRE, etc.

How obtain complete source code for applet demos?

I would like to obtain the source code for all the class files for the applet demos, especially the molecule viewer. Some of the class files do not have corresponding java files made available. Who can help me out?

Which class files are missing?
If you go to this site, select the applet of interest, the link at the bottom of the page (that is, the page with the running applet in it) takes you to the source. The file at that link includes all of the classes in the applet.

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Is it necessary to add? If so, how do I add H Tags to iweb.

I am running 10.6.8 and using iweb for my web site. After several SEO analysis they all indicate I need H1-6 header tags. After looking at the source code I see there are none in iweb. Are they necessary to add? Why would one add these tags and how do I add H Tags to iweb? And are there examples to look at? I am slowly learning about simple web design and assumed that iweb was stand alone without having to write code. Is this one of the reasons iweb is no longer supported? Thanks for looking at this!

A simple text page like this:
Heading
    sub heading
          text paragraph ....
Is traditionally represented by html tags like:
<h1>Heading</h1>
     <h2>sub heading</h2>
          <p>text paragraph ... </p>
I would guess that the use of h1-h6 tags helps search engines to understand the structure of a page as the tags imply a certain structure.
This can be compared to more generic tags like <div> that could represent any kind of content - and may be what iWeb uses (you'll have to check yourself).
I would generally recommend that you use some kind of up to date blog/site building tool, perhaps Wordpress or Squarespace (I haven't used either one myself) that support current web technologies - this should reduce your SEO issues and make it easier to properly support mobile/tablet users.
