Casting AxisFault from InvocationTargetException.getTargetException)

[Larry Tan]

Hi,
I'm currently using Java Reflection to load my service locator, getting 
ports and invoke operations. Everything works fine for me apart from catching 
exceptions. As I'm currently aware, whatever AxisFault thrown by the web 
service call is wrapped under my InvocationTargetException which is available 
to me via the getCause() or getTargetException() method.

However, I cannot seem to cast the AxisFault into my specific exceptions. 
Given my port type operation signature is like this

public void myop(pars... ) throws ... MyPackage.StringMessage;

My (reflection) Java code are as follows

try {
Method methodOp;
Class serviceLocatorClass = Class.forName(...);
Object serviceLocator = serviceLocatorClass.newInstance();
Method getPortMethod = serviceLocatorClass.getMethod();
Object port = getPortMethod.invoke(serviceLocator, null);
Method webServiceOp = port.getClass().getMethod(myop, parClasses);
Object result = webServiceOp.invoke(port, pars);
} catch (InvocationTargetException ex) {
if (ex.getTargetException() instanceof AxisFault) {
Class stringMessage = //  do loading of StringMessage via 
forName

ex.getTargetException().getClass().getName();// returns 
AxisFault which is not what i want as i'm expecting StringMessage
stringMessage.cast(ex.getTargetException());// 
encountered ClassCastException
}
} 

When my webs service throws StringMessage exception (I'm certain this is 
the thrown), I cannot seem to cast it successfully. I found out that 
ex.getTargetException().getClass().getName() returns me AxisFault instead of 
StringMessage.

I then try the static way, which
try {
port.myOp(...);
} catch (AxisFault ex) {
 ex.getTargetException().getClass().getName();// returns 
StringMessage!
}


Would appreciate advice on this! Many thanks in advance!

Best Regards,
Larry

Distinguish axis engine(s) in Tomcat

[Larry Tan]

Hi,
I'm new to Axis. I'll like to find out if i have 2 servlets (both 
extending
AxisServlet) deployed under same webapp, will there be 2 separate engines or
both of them sharing 1 Axis engine? Is there anyway of distinguishing them?
Another question: If i have a subclass of AxisServlet in a webapp and
AxisServlet in another webapp, it'll be 2 Axis Engine i suppose? Is there
anyway of letting them share 1 engine across different webapp?
The reason i asked is because I'm trying to get ActiveBPEL to work with
WSRF (deployed in Tomcat).

Thanks,
Larry Tan
