Also, it may be of interest to know that putting a jar file into your build path in a Web Application (I am assuming you are using WSAD since this is the WebSphere forum) will only help at compile time. Not runtime in the
Test Environment.
Putting the jar file in the build path of a Java Project will be effective at both compile time and run time.
It's like Jeanne stated, if you have a need to modify the code, importing the jar should break it out for you so that you can modify it. In which case you may want to keep it in a separate Java Project. If you plan on using this Java Project in a Web Application,
you should put the project in the Web Application's list of web Library projects (right click->properties->web library project). Otherwise, if you plan on using this code in another Java Project just put the newly created Java Project in the build path....
