I use eclipse and in the debugger the classpath looks correct. I traced into
the code and in org.apache.axis.handlers.HandlerChainImpl class newHandler()
method the code is throwing a class cast exception:
private Handler newHandler(HandlerInfo handlerInfo) {
try {
Handler handler = (Handler)handlerInfo.getHandlerClass()
.newInstance();
handler.init(handlerInfo);
return handler;
} catch (Exception ex) {
String messageText =
Messages.getMessage("NoJAXRPCHandler00",
handlerInfo.getHandlerClass().toString());
throw new JAXRPCException(messageText, ex);
}
}
The call to neInstance() above casts the result to
javax.xml.rpc.handler.Handler but SimpleSessionHandler does not implement
javax.xml.rpc.handler.Handler interface. It implements org.apache.axis.Handler
and is a subclass of org.apache.axis.handlers.BasicHandler. I must be
installing the handler in the wrong object. Any idea how I can install the
SimpleSessionHandler using the code from DynamicInvoker class in the axis
examples via code?

System.getProperty("java.class.path")

Subject: RE: Axis 1.2 handlers
Try googling on this error - its a common one that has
nothing to do with handlers.
My guess is that its really not in your client
classpath. If you're able try executing the client
with ant, which does a good job of resolving this type
of stuff. Otherwise i'd double check your classpath
very carefully.
