Writing Java code for Jbase

I have come across a library that i call use to write code in java for jbase. My challenge is that i don't know the location of the library <com.jbase.javaobjex.*;>. Does this library come with jbase install by default or i have to acquire it.

My jbase is running on java red hat linux 5.5

What you are trying to achive?

Are you trying to connect to a different database from jBASE using javaobjex?
Or you want to write your JAVA programs inside jBASE and call using CALLJ?

javaObjex is a jar file which comes with jbase releases. When you start it (javaObjEXServer start) a listener for java code at port 3570/3575 is started on your server.
