Hi there and welcome to Javaranch!

Have you double checked your CLASSPATH and that the JARs actually contain that class/method?

[Ernest Friedman-Hill]

That's the sort of error you can get if the version of iReport you use when you compile the code is different from the version that's present in the application server environment. Make sure that both your IDE and your deployment environment are using the same versions of all libraries.

Just change the server to GlassFish.
