Hi, I want to embed some version information into a class file, but I don't know that much about the java class file format. The standard way would be to put it in a String, but that would mean changing all our millions of source code files, some of which hasn't changed for ages. There are ways of putting arbitrary information in executables, I was hoping I could do that with class files. Either with a task or some other tool. I see there is an attributes entry in the class spec... Any ideas? thanks, jamie Visit our website at http://www.ubswarburg.com This message contains confidential information and is intended only for the individual named.
