Adding Custom Jar to JasperServer

[CoffeeKid]

Hello,

 

I've created a custom class called SecToTime that converts seconds (a long value) into a string formated in XX:XX:XX

 

So this would cause an long value of 209 to be come 00:02:29

 

I've made the jar file then added it to iReports, and used the following in a text field:

Code:

new SecToTime($V{variable}.longValue()).toString()

 

when i compile the report in Ireports, it works perfect, but trying to add the .jar file to jasper server has caused me some problems.

 

I've added the file to the common/lib dir in tomcat, even tried to modify tomcat's class path, all of which give me the following error:

 

Error Message:

What am i doing wrong?

 

Thanks

The JVM used by tomcat cannot load your compiled. Use the same Java version or specify source and target versions when compiling the class.
