Hi,

You should build all the java class and import them. This error is usually when you change one class and you dont compile and build the rest.

All the java classes are built.In this program there are 2 classes eho,myecho.

Hi,

When you make the jar to import to XI you must verify the two classes are generated at the same time. Later you can verify in Inteface Mapping that you are using the myEcho class to do the java mapping.

Plesae verify the java version are the same in you own machine and the xi machine.

Regards.
