Hi I have a client application,its an applet which will download the jar files onto local drive from a server. So I used JRat to find the memory leaks inside the Java Code and instrumented all the jars and placed those jars in the directory where the server will keep the new jars. I used this procedure to fix the bugs, by changing the code and creating the jars and keep those jars in that directory. When I try to launch the application, these instrumented jars are again getting replaced by the new jars from the server. So can anyone suggest some ideas regarding this.
