Things to try

Jason,

First things to check:

1) If you are using jdk1.2.*, is the .jar in the jre/lib/ext directory? If previous versions are being used: Is it on your classpath?
2) Are you invoking your class as follows:
for jdk1.1.*
jre -classpath x.jar blah.blah.ClassName
for jdk1.2.*
java blah.blah.ClassName
3) Does your jar or Class refer to any classes that are not on the class path? If so, include them all in the class path.

hope this helps.
