noSuchMethod exception

[Mahesh Bamane]

Well, I've been dealing with a big problem. I have two classes which has same class name and package structure they are present in two different jars for sure.
When I call a method of one class say for example setName.
I get an exception saying noSuchMethod; what can be the possible soluntion in this regard.
As classes are in jars I cant make any changes to them.

[Zandis Murāns]

As long those jars are not signed (and in some cases even if they are) you can rename jar file to zip and do all the changes you want.

[Rob Spoor]

You don't even need to rename them; JAR files can be opened with all ZIP applications just fine.

But two versions of a class seems like a bad design. Is this a class written by yourself or a colleague, or did you get the JAR files from the Internet?
