After you have added jar file to build path you have to restart your Jasper Studio.

You have added the JAR file in the right location, but the issue (looking at the error message) is that the reference to the external class has not been provided.

Select the Field or Variable which needs to be run the new class (from JAR file). change the Class of the fields to your new class and run the report. You will have no errors then.

'In Jaspersoft Studio there is no longer a big unique classpath for the whole application like in iReport.

Each report is supposed to be part of a project. The project has a classpath, and here is where you should add the jars you need.

All is done by opening the projects view and right click the project folder with which you are working on. By default, new reports are created in the project "My Reports".'

In order to get the JRXML attached working what you will need to do is

Import the jar Tools(in the iReport Menu bar )-----> Options ----- > Click on Claspath Tab ------> ADD Jar -----> choose the JAr file (I Think You missed this step You need to import the JAR file through iReport through the above described process, no need of using IDE for classpath setting use iReport only)

It works for me.
