First you have to ensure that this Java class is in the classpath of the java process that runs the report.
When designing the report that means that the java class and your report have to be in the same eclipse project. If they are in different projects your report won't be able to find the java class.
If they are in the same project you can do some scripting with it. You have to keep in mind some rhino script "specials" like the package adressing of java classes. For your self written java class you have to add the word "Packages" when trying to reach the class inside a rhino script expression
e.g.:
i assume that the Java class MyLib is placed in the java package org.example

so you can reach it with the following RhinoScript expression
var javaObject = new Packages.org.example.MyLib()
now javaObject contains a instance of a java object of type MyLib
you can then work with it in rhino script
e.g.
call javaObject.returnLib() inside rhino script

Hi Swetha,

Are you trying to get a class file to work with the designer or when deployed? Or both?

SiddamS

Swetha,

When you say "user defined class", do you mean they have their own class they want to import or they choose from a parameter list of classes you already have or something different?

SiddamS

They have a their own class(given jar file),I need to use that class in My Javascript Event.

Swetha,

But you have a copy of the class file to deploy out to your server? It just depends on which user which function you need to use?
