InvocationTargetException

[Ivan Aguirre <iv...@gmail.com>]

Sorry... it's a large message, but if anyone could help me ;)...... thanx ....

I have an strange fault when calling a Axis Web Service. I use two methods:
getPagedUserReport and getPageFromReport from the same WS, called "Report".

The caller code:
***********************************************************************************************
ReportService service = new ReportServiceLocator();

Report port = service.ReportService("someUrl");

Stub s = (Stub) port;
s.setUsername("duke");
s.setPassword("java");

Request request = new Request(....); //Request is one of my self WS
parameters...

request = port.getPagedUserReport("duke", request);

pages = request.getPageNumber();

String page = null;
for (int i = 1; i <= pages; i++) {            	            
	time = System.currentTimeMillis();
        page = port.getPageFromReport(request);
        /* do sometinhg with page....*/
}
***********************************************************************************************


Some other issues:
-> I use Tomcat 5.0.18, Axis 1.1 and j2SDK1.4.1_01.
-> The scope of the service is "Session."
-> I changed the Stub (generated by WSDL2Java) to work with Sessions
(adding a "_call.setMaintainSession(true)" )
   at a point in the code.
-> The fault occurs when I execute some clients at the same time. Some
of them get the fault.
