Would Tal clear this up, please? I'm intrigued.
I feel like everyone else understood that you want to know if you changed the interface of your own class while I read your question that you want to know if the new version of the class depends on new external code. Who's right?
Thanks,

maybe i don't understand, why do you need to do this? usualy you use the interface mechanism for this. i.e: create an interface that this class should implement and make sure your internal java files know about this interface. and u'd never have to worry about it. if you both use/implement the same interface then it has to comply, else it wouldn't comply. just make sure you put the interface in a seperate java file and that you both use it.

I'm looking for a solution for internal affairs :-) not with clients...
we do that class changing thing allot here, and looking for a way to resolve this "dependency" issue.. I have the sources.. no need to decompile...
Is there a tool that supports this advanced "versioning" issue?
Thanks, Tal.

Well,
I hope you guys don't use an obfuscator :-) What I would do is first check CVS (or whatever you use) and see what changes were made in the class. If you find that these changes are to dramatic then you can get the class from the clients application, decompile it (google java decompiler) fix the code, recompile and send them the fixed class. Ugly yes! But it should work.
Be good. Ron

Yes, When I wrote the mail I was confused myself - as there is no real "link" in java...
here's the problem:
I have to supply a patch for a software build 18, and am currently working on build 22 of the same software.
I wonder if I can just give them the class from the b22 and put it instead the patch requiring class of the b18...
Now I need to wait until runtime to see if this class really fits... :-)
seems like I'm not the first to hit this problem... as in the C world you simply "link"...
(I know the class from b22 compiles... I don't know if it "links" with all the others correctly... [lets say a method signature changed])...
Do you know if there is a "solution" in the industry??
Tal.

How do you mean **links**? AFAIK Class files are independent and are executed as such by the JVM, There is no traditional linkage done in Java and there is no linker. The JVM is responsible to download all the referred classes that you class refers to AT RUNTIME...
I hope I understood the question well, please feel free to ask again or elaborate your previous question.
Regards
Ron

Hi all
Is there a tool / method to check if a compiles java object (class) links correctly?
Any thoughts?
Thanks, Tal Achituv.
