Trouble using a custom JAR from a report in JasperServer

[schultcd]

I have written a custom library that includes some helpful date-related utilities like getCurrentQuarter, getLastQuarter, etc. and I've been using it to great effect in my own set of command-line scripts to launch reports, package them, and deliver them to wherever they need to go.

Now I'd like to move to JasperServer and when I launch the report, I get this exception:

I have placed my custom JAR file under webapps/jasperserver/WEB-INF/lib and I restarted Tomcat (successfully).

Any ideas?

Linux x86-64, Oracle Java 7, JasperServer 5.2.0
