Hi,
I am trying to use axis2 in my eclipse plugin with the JDK 1.5
I generated a stub and a callback handler of a WSDL with the WSDL2Jave
eclipse plugin.
I tried to use the auto-generated classes both ways: callback and direct
calling a function.
However nothing *happens*, the plugin/eclipse just hangs;
all i get is this:
log4j:WARN No appenders could be found for logger
(org.apache.axiom.om.impl.builder.StAXOMBuilder).
log4j:WARN Please initialize the log4j system properly.
Unhandled event loop exception
Reason:
java.lang.NullPointerException
Debugging resulted in this:
in Window.class
################### CODE STARTS ###################
private void runEventLoop(Shell loopShell) {
[...]
try {
if (!display.readAndDispatch())
display.sleep();
} catch (Throwable e) {
exceptionHandler.handleException(e); /* <- This
exception is thrown! */
}
display.update();
}
################### CODE ENDS ###################
my code causing this problem (callback way, same for directly calling):
################### CODE STARTS ###################
private void testService() {
cbh = new GetEntryServiceCallbackHandler(this) {
public void receiveResultgetSupportedFormats(
uk.ac.ebi.www.ws.services.urn_dbfetch.GetEntryServiceStub.GetSupportedFormatsResponse13
param1) {
if (param1 == null)
testServiceResponse("Error 4");
else
testServiceResponse(param1.toString());
}
public void
receiveErrorgetSupportedFormats(java.lang.Exception e) {
testServiceResponse("Error 3");
}
};
try {
service = new GetEntryServiceStub();
}
catch (Exception e) {
testServiceResponse("Error 1");
service = null;
}
if (service != null) {
try {
service.startgetSupportedFormats(cbh);
}
catch (RemoteException e) {
testServiceResponse("Error 2");
formats = null;
}
}
}
private void testServiceResponse(String response)
{
label2.setText(response);
}
################### CODE ENDS ###################
How can I solve this problem? where to start!?
