Hi you all !

Quick question:

I defined a Service Entity like this:

1<entity name="Test" local-service="true" remote-service="false">
2        <column name="part1" type="long" primary="true" />
3        <column name="part2" type="long" primary="true" />
4        <column name="part3" type="long" />
5    </entity>


"part1" and "part2" are forming a Primary key.

A class called TestPK has already been created for me.

To store a new "Test" object, I need first to create a new TestPK and use it to store the Test object.

1TestPK testpk= new TestPK(someValue, anotherValue);
2TestLocalServiceUtil.createTest(testpk)


But whenever I do this I get the following exception:

121:26:12,708 ERROR [ClassLoaderProxy:70] java.lang.IllegalArgumentException: argument type mismatch

Hi Daniel!
Since ClassLoaderProxy used, I suppose you defined services in one portlet - and trying to use them from another portlet.
Is it your situation?

Hi Daniel!

I've used the same and its working fine.

I am using LR 6.1EE and defined services in one portlet and accessing in another portlet.

This is a class loader issue. You cannot create the instance in the portlet consuming the service and pass it to the portlet providing the service.

In the portlet providing the service, edit the TestServiceImpl class and make a "Test createTest(long someValue, long anotherValue);" method that invokes the create process and returns the instance. Portlet consuming the service would use this method.
