Thanks for replying.

I downloaded the "net.sf.jadclipse_3.3.0.jar" from

http://jadclipse.sourceforge.net/

But I am facing a few problems.
1. It says that JAD is for Eclipse 3.3 but I have eclipse 3.4
2. In the article it says execute jad command from prompt. When I do that it says "jad is not recognized...". This happens even when I execute this command after navigating to "c\jad" folder. I have set "JAD_HOME" as "c:\jad", classpath as "c:\jad\net.sf.jadclipse_3.3.0.jar" and PATH as "c:\jad"

think you need to install from update site for 3.4

 

by: ank9Posted on 2009-08-30 at 21:09:29ID: 25220476

Can you please let me know where is the update site?

>>http://java.decompiler.free.fr/?q=jdeclipse

Is this a different plugin?

>>Have a look at the link above, gives a full list of instructions.
Thanks it does contain all the instructions. I also has a link to the "update" site. But when when I click on this link

http://jadclipse.sourceforge.net/update/

It gives me the below mentioned error

So I tried to configure it with the plugin for eclipse 3.3 (although I have eclipse 3.4) using the steps mentioned in the link.
Now when I click on the .class file from within eclipse, it still opens the file in the eclipse viewer even though Jad viewer is set as the default .class file viewer. Please refer to the attached JPG file

by: a_bPosted on 2009-08-30 at 21:28:56ID: 25220518

Donot click on the update site, add to eclipse.

 

by: ank9Posted on 2009-08-30 at 21:30:11ID: 25220523

I followed all the steps mentioned in

http://java.decompiler.free.fr/?q=jdeclipse

Now when I open eclipse, I also see a menu item called "JadClipse --> Decompile". But when I click on this menu nothing happens

 

by: ank9Posted on 2009-08-30 at 21:34:02ID: 25220534

It does show an icon for the class file but still class files open in default Eclipse viewer
Please have a look at the screenshot

 

by: ank9Posted on 2009-08-30 at 21:38:06ID: 25220542

Now I have both the plugins installed but none of them is decompiling the class file.

 

by: a_bPosted on 2009-08-30 at 21:45:22ID: 25220561

Did you restart eclipse?

 

by: ank9Posted on 2009-08-30 at 21:48:36ID: 25220575
