I apologize for being completely off-topic (this question has nothing to do

(file:/etc/BlueVueBatch/BVBDatabases/PostgreSQLDatabase.jar) instead of
the weirdly formed one below, but I get the same error message. I guess
it will load the classes in that JAR either way, but (as I expected),
the format of the URL does not make a difference for

Don't forget Tomcat&#x
it's a Java/JVM based concept, but understand that Tomcat itself is running in
the JVM, so classloading can be relative to tomcat, or whatever you have
