Service invoking Client

[Larry Edwardson <bu...@tpg.com.au>]

Hi guys,
my problem is that I have a remote method that is called via Axis, this
method searches it's local database for some other web services, when it
finds the path it tries to connect to the other Web services, via threads.
Question:
Can one Web Service call another, and if so how do we create more than one
Service Object running in the same JVM, I am having great difficulty doing
this.

It have it working at the moment from one service to another no problems,
but when the second service tries to call a third service, the first service
falls over with this:

AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

This happens at the point where the second service calls, Service service =
new Service(); to call the third service,
sorry if this is confusing.
If anyone has any experience running multiple clients within the same JVM, I
would greatly appreciate a reply.
Thanks
