where to find jars
This table should help you locate missing jars. To use a jar, it usually must be mentioned on the classpath or put in the ext directory. For Servlet wombs, there may be special project-specific places to put them. If the jar you are looking for is not in this list, check the C:\Program Files\java\jre7 /lib and C:\Program Files\java\jre7/ext directories. Please email me with suggestions for additions to this table. Use your browser local search button to find the package or jar name of interest in the following table. Only the higher order package names are shown, not the full trees.

Finding Classes

If the class you are looking for is on the classpath, you can find out which directory or jar or URL it came from with
To discover what your program is using as the classpath use:
