Answer 1

This is a sub-optimal solution. Renaming a jar file to remove version information can cause problems later. How will you know the version for which you check documentation, bugs, etc? Also, the root directory of your file system is not the best place to put java archive files. It can get pretty crowded for a complex application. I suggest you create, for your project, some directory where third-party jar files can maintained. We do this for each project.
