JDK Source code

Does the source code for the standard java libraries come with the sdk? I thought that was the whole point of an sdk, but when using eclipse, it says it cant find the source (in rt.jar), and just gives me an outline of the class. Do I separately have to download the source code? I saw something like this somewhere on the site (SCSL or JRL), but am not too sure if that's what i'm looking for...
Cheers,
Siam

Some of the code is in other jars. Other code is not distributed as part of the SDK; it can be downloaded using the source code d/l link on the download page.

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

How do I obtain JDK source code?

I need to get the source code of JDK 1.4.2 for Mac OS X to help debugging my Java application. Where can I obtain it? Is it the same one as those distributed by Sun?

I fail to see why having the JDK source is going to
help you debug your code.I fail to see why you think your comment is in the slightest bit helpful.
When programming an API, you should always include enough documentation and properly use exceptions so that someone using your API is able to determine exaclty why they are getting any error that they may encounter.
Not all programmers provide adequate documentation in all instances and and not all programmers provide adequate exception support in all instances.
The standard java libraries are no exception to this. I have encountered a few instances in my coding history where the documentation/error messages were not sufficient for me to know what I have done wrong. In these instances, going to the source code allowed me to figure things out. This is why sun releases src.zip with their jdk's.

JDK source code of earlier versions

Hi,
I'm doing some research on code clones. I wrote a tool to categorize code clones and i would like to test it on several open source projects. I found a paper of another researcher that did similar research in the past and he also used several open source projects. To compare my results with his results i'd like to take the same projects. One of them is JDK 1.1.5, but i can't find the source code on the internet. I only found the source code of JDK 1.5 and 1.6. I'd like to have the source code of version 1.1.5 or at least a version earlier than 1.5. Can anyone help me?

Check the src.zip file in your jdk folder.

Attatching Source Code To Eclipse IDE

Please please please can someone help me do this? Its driving me nuts
I am running JDK 5 and have downloaded Java 5 source cide - I have attatched the code to Eclipse and it still does not show it.
I have tried this on more then one machine with no luck
Does anyone know what might cause this and how it can be overcome?
How do you get the JDK source code available within Eclipse?

Steve_Johnson wrote:
I am running JDK 5 and have downloaded Java 5 source cideBut is your Eclipse actually using the JDK? Or just the JRE? Eclipse doesn't need a JDK to run, or to compile code, it'll work just fine with a JRE. Have a look at Windows->Preferences->Java->Installed JREs in your Eclipse, and see what it's actually using. If it's not a JDK, chances are it won't pick up the sources

JVM 1.4.2 source code ?

Where can I gett the source code of the JVM bundled with Java 1.4.2 ?

How to get the source code in PAR file

Hi All,
I used the PAR migration tool to migrate from PAR to EAR file. When I imported the EAR into NWDS 7.3, I was just able to see the structure and jsp files and could not find the java source code files. I would requires the java source code to make modifications so that deprecated APIs can be replaced and to also make the code compatible with JDK 1.6.
I think the original 7.0 PAR file itself does not contain the source code. I decided to use the "Include source code" option when exporting the 7.0 PAR.
I have the portal application DC project in my NWDS 7.0. However, when I try to export the PAR file using Export --> PAR File -- > Next... I am unable to select any project from the list. The list appears blank with disabled Next & Finish buttons.
I also noticed that in the portal DC application structure, there is a .sda file under /gen/default/deploy. Also there is no PAR folder under /gen/default/public.
How do I include the source in the PAR file so that I can edit the same after migrating to EAR format ?
Regards,
Melwyn

DC and PAR/EAR stuff are different formats, SC/DC is an archive type used by NWDI, if I got it right.
How do I go about generating the PAR file (with source) ?
In fact through including the seources while creating the PAR/EAR in NWDS, but: no need to do that, you can also depack SDA (rename it to zip). If you wanna just see the Java sources you will find them there, otherwise decompile as Vijay already sad.
cheers

How to read the Java source code (in Netbeans)

I use OS X10.5.5, NetBeans 6.1 and JSE 6 on a 64 bit mac.
When I downloaded NB6.1 it had JSE 5 as it's default (and only) java platform. I ran Software Update to get Java 6 from Apple, used the Java Prefrences utitlity to set JSE6 as default. In NB I added the JDK6 platform, registered the JDK6 javadocs and noticed that I also have the option of registering the Java source code.
I have three questions:
1) How do I make JDK6 the default in NetBeans. The JDK5 keeps being default after I did the steps above and I don't see anywhere to change that.
2) How do I read the Java 6 source code? I can see sun provides [source code| http://download.java.net/jdk6/] for their supported platforms. I dont see Apple doing the same for its JDK port. What would I need to do to get to read the java SE6 sources? or is it actually hiding somewhere in the /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home hierarchy?
3) Where does the JVM look for the binary code to run when I make a call to, say java.util.ArrayList or any other library. In my naivety I would have assumed it would be a .class file somewhere in the java Home folder, but I don't see anything like it.
thanks in advance,
chris

This is taken from the help included with netbeans. In response to question 1.
By default, the IDE uses the version of the Java SE platform (JDK) with which the IDE runs as the default Java platform
for compilation, execution, and debugging. You can view your IDE's JDK version by choosing Help > About and clicking the
Detail tab. The JDK version is listed in the Java field.
You can run the IDE with a different JDK version by starting the IDE with the --jdkhome jdk-home-dir switch on the command line
or in your IDE-HOME/etc/netbeans.conf file. For more information, see IDE Startup Parameters.
In the IDE, you can register multiple Java platforms and attach Javadoc and source code to each platform. For example, if you
want to work with the new features introduced in JDK 5.0, you would either run the IDE on JDK 5.0 or register JDK 5.0 as a
platform and attach the source code and Javadoc to the platform.
In , you can switch the target JDK in the Project Properties dialog box. In , you have to set the target JDK in the Ant script itself,
then specify the source/binary format in the Project Properties dialog box.
To register a new Java platform:
Choose Tools > Java Platforms from the main window.
Click New Platform and select the directory that contains the Java platform. Java platform directories are marked with a
in the file chooser.
Use the Sources and Javadoc tabs to attach Javadoc documentation and source code for debugging to the platform.
Click Close.
To set the default Java platform for a standard project:
Right-click the project's root node in the Projects window and choose Properties.
In the Project Properties dialog box, select the Libraries node in the left pane.
Choose the desired Java platform in the Java Platform combo box.
Switching the target JDK for a standard project does the following:
Offers the new target JDK's classes for code completion.
If available, displays the target JDK's source code and Javadoc documentation.
Uses the target JDK's executables (javac and java) to compile and execute your application.
Compiles your source code against the target JDK's libraries.
If you want to register additional Java platforms with the IDE, you can do so by clicking the Manage Platforms button.
Then click the Add Platform button and navigate to the desired platform.
To set the target Java platform for a free-form project:
In your Ant script, set the target JDK as desired in the javac, java, and javadoc tasks.
Right-click the project's root node in the Projects window and choose Properties.
In the Sources panel, set the level of JDK you want your application to be run on in the Source/Binary Format combo box.
When you access Javadoc or source code for JDK classes, the IDE searches the Java platforms registered in the
Java Platform Manager for a platform with a matching version number. If no matching platform is found, the IDE's default platform is used instead.

Scrolling messes source code on JDeveloper 10.1.3.5 Windows 7 (64 bit)

Hello!
One can only work around the problem as in vista, by using a new Sun jdk, other than that shipped with JDeveloper.
However, this is not considered safe, as the newer jdk is neither tested nor certified to work with that version of JDeveloper.
I have already searched My Oracle Support, only to find a patch about a memory leak for JDeveloper 10.1.3.5. +(I wonder why is it not offered to the public anyway?+)
Could any one from Oracle please see to a more permanent and safer solution to the problem?
I am looking forward for your prompt actions, and thank you very much in advance!

Let me rephrase: when one scrolls using page up or down keys, or by using a mouse wheel, the source code lines ( and characters) appear partly only, either distorted or overlapping with each other, in such a way that one cannot make out what has been written. I hope the above clarifies the problem in question. In such a case a screen shot might actually serve us perfectly.
I have already given your suggestion a try, without any success.
Thanks anyway very much for your reply!
Any other helping hand available?
TIA!

Why are the Java Library source code classes not indented properly?

I have always admired the design of a lot of classes and frameworks in the JDK. I read the source code a lot to see how the developers coded a particular class, how they designed it and how they write the javadocs.
But one thing I observed was the improper indentation of the source code. Why is this so?

Where can I get the source code for sun classes?

Hello,
When ever you download sun's j2sdk, the archive always contains the source code for the entire sdk in a zip file called src.zip except the sun.xxx classes like sun.awt.print.PrintDialog or sun.awt.font.FontResolver.
For debugging purposes I need, if availabe, the source code of these classes which are not present in the src.zip.
Please can someone tell me if theses classes are available as source and can point me where I can find it cause I am searching for it but can't find it on the net.
Thank you
Carolin

Hey ChuckBing
And your way is the only way, right? No.What on earth is eating you? Highly sensitive today?
Where is the problem? There are two solutions of the question.
The one link I posted points directly to the sun source download link. The "readme" explains, yippie, the sun sources are contained. Easy, isn't it?
With the other one, you have to navigate at least through two other pages before you might find the link and only if you recognize that "Download JDK 5.0 source via SCSL/JRL" means the sun source code and not the sources contained in the JDK download. This is what I thought as I've seen this link the first time. Unfortunately there is no "readme".
I prefer the easy way, I dont want to earn a doctorate. Ok, you can say dont "play the woman", but I'm a woman and a blonde too;-)
But, let us stop the idle discussion here, please!
Nevertheless, thanks to you and [email protected] for answering.

Of course a university degree is not the only way you can learn this, but the matter is so complex that it's not just a matter of reading a two-page tutorial.Exactly. And as I see it, learning compiler design etc. is more fitting for university than learning programming languages, which is an even longer process.
Of course the programming classes given don't claim to teach more than the basics that are required for the theory of the more advanced classes, but some
people don't realize that.

JPDA source code

Where can i download JPDA source code ? I search the net a bit and found JPDA faq's that its available at jdk.java.net. I downloaded JDK source and searched it and found nothing about JPDA except tools.jar file (and its all classes no source code).

The JPDA source code is part of Open JDK. You can download the Open JDK code here:

DrawArc Method source code

Where can i find the actual source code for the drawArc Method of graphics. I've already check the
Graphics class and found that drawArc is a abstract method. However there must be some place in the jdk that the actual source code is.
Please help

The implementation of Graphics that is used will depend on your operating system. You can get the class name from your Graphics instance using graphics.getClass().getName(). This should point you towards the class file you're looking for. I suspect you'll have to decompile it to get at any sort of source code, though.
I would also imagine that on many operating systems this is a native call to the underlying windowing system.

How to get / view Java Sound source code

Hi All,
I'm curious to view the Java Sound source code, is that possible? Let me know what I have done so far,
1. In eclipse I have mapped the src.zip from the JDK directory, now I am able to view most of the source code.
2. When I try to view AudioSystem.getProviders method it returns value from JDK13Services.getProviders
But I dont have source code for JDK13Services class, indeed i don't have com.sun.media package source code, in the src.zip
Do anyone know how to get com.sun.media package source code?
Thanks in advance,
Karthikeyan R

It appears that the 3rd entry of this search
[http://www.google.com/search?q=JDK13Services]
give both the javadoc and source for JDK13Services, as follows:
[http://www.docjar.org/docs/api/com/sun/media/sound/JDK13Services.html]
The other search listings appear to contain useful information, also.
