Is there an easy way to attach source in Eclipse?
(17 answers)
Closed 7 years ago.
I have attached the source code of rt.jar file ie src.zip to my Eclipse.
My problem is that, After adding the source code of rt.jar to eclipse, when I open any class,for Example "String" class, The eclipse itself showing ".class" file for "String" only,It does nopt showing ".java" file for "String".
How can I see the ".java" file?
The source file is exactly that, the source file. You are reading the files in the .jar. Adding the source is not a magical way in which you can edit the .jar. If you could change the underlying Java source code it would be one of the biggest security risks. The .class file is a representation of the .java file and as such there is also no reason for you to need the .java file.
Did you try to attach the source code, as shown in the below screen shot.

We have jar files on the server that are run on a schedule, but I don't think the code I found is matching what's on the server. What's in clearcase does not have jar files to compare sizes/dates.
Is there a way to extract the original .java text contents from the .class files when I open the .jar file with 7-zip? The class contents have garbage in them since they are a result of compiling. Then I can compare the class contents with what I found in clearcase and see if the errors I'm seeing were in the release a few years ago. The people who worked on this don't work here anymore.
I'm not finding what I'm looking for in an internet search. It could be it's not possible. In my search, I'm just finding how to unzip the jar file and see the .class files there but not the original class text contents.
I'm using SDK 1.8.0_2-2, SDK default 8 (lambdas etc).
Thank you!

A JAR (http://en.wikipedia.org/wiki/JAR_%28file_format%29) file is a ZIP-compatible archive of your compiled classes and other binary resource.
Feel free to unpack/pack it or treat it the way you treat ZIP-archive, say using your favorite archiving tool, like 7zip.
You can even create a ZIP archive with the contents you wish your JAR to contain and simply change the file extension to .jar.
NOTE: in case you use compression for your ZIP-archive, because in that case your manifest often must be the first entry in the archive.

How to decompile a whole Jar file?
I have a .jar file. Its a single file, but I want to "decompile" it to get at the original java code (or at whatever would be closest to the Java code - something I could understand, and edit). I believe my file is (specifically) a java applet, but its saved as an executable jar file (.jar).
How would I do such a thing?
Take a look at Java Decompiler.
It allows you to decompile jar files with the JD-GUI and browse the class files as source.

You can use java decompiler
In principle you can decompile any jar file, by using ,for example, JAD
http://en.wikipedia.org/wiki/JAD_%28JAva_Decompiler%29
But if the jar was obfuscated the result may not be very pretty. ;)
My fav decompiler is cavaj, you can download from the following url
http://cavaj-java-decompiler.en.softonic.com/
Normally are in a "jar" archive only the compiled Java files (". class"). But you could theoretically try to decompile these files.

How to make a JAR file that includes DLL files?
(2 answers)
Closed 9 years ago.
I have a third party library that comes with .dll files that I need in order to run my java jar file. How can I include them in my jar file when I deploy my application? (I am using JSmooth to create an exe file - if that helps anything)
NOTE: I have looked at this stackoverflow question, but there's only one answer there, and I don't think it will work for me.
Thanks so much!
this has come up before. the short answer is that you cant - the dll has to be accessible to the underline OS and so cannot be inside the jar.
it can, however, be unpacked from within the jar to somewhere in the PATH before you call loadLobrary ....
