I downloaded an app on Fedora Core 6 that uses the jikes compiler but get the following when running make:

*** Semantic Error: You need to modify your classpath, sourcepath, bootclasspath, and/or extdirs setup. Jikes could not find package "java.lang" in:

Java development was installed using the standard FC6 Add/Remove Software.

What should classpath etc. be set to?

In case there is any doubt, I've never used java before.

Thanks
