Why only some classes on jar are found

does anyone know how can java find only part of the jar?

I created a lib that does some reporting and I'm integrating it into many different projects. This particular error only happens on those running inside tomcat.

Exception in thread "cron4j::scheduler[10f8a8a406870a5b0d2142230000014bdf89373949886ac4]::launcher[10f8a8a406870a5b3adcceb60000014be0e6d840729614e1]"

I checked the jar and it has the class. Also checked if there's more than one JAR on the classpath.

Use the java -cp option to include the class in the classpath. – René Winkler Mar 04 '15 at 07:30
The class is in the classpath. You can see by the stacktrace that some classes from the same jar were found previous to the error. – Gust Mar 04 '15 at 07:31
Are you sure you do not have 2 versions of the JAR: for instance one in the parent/tomcat lib folder and one in a war ? – Bruno Grieder Mar 04 '15 at 10:27
Yes, I verified that. – Gust Mar 04 '15 at 13:38
