[Axis2] How web-services works with external jars?

[Smirnova, Natalya]

I have such problem: I want to add external jar to build path in my web-service. I use objects of classes from this jar in method, which is described in service.xml. But my client for this method display errors, such follows:       org.apache.axis2.AxisFault: unknown       at org.apache.axis2.description.OutInAxisOperationClient.execute(OutInAxisOperation.java:287)       at org.apache.axis2.client.ServiceClient.sendReceive(ServiceClient.java:457)       at org.apache.axis2.client.ServiceClient.sendReceive(ServiceClient.java:399)       at client.TestMyService.main(TestMyService.java:27)……………………………………………………………     Best regards, Smirnova Natalya.
