You should try to extend
the class BasicHandler from org.apache.axis.handlers instead of GenericHandler
from JAX-RPC.
BasicHandler is the base
class of all the handlers built-in with Axis.
You may replace the GenericHandler’s
methods handleRequest and handleResponse with BasicHandler’s invoke.

Objet : classCastError after
deploy a customized handler
I developed a customized handler which extends
GenericHandler and implemented it to log soap request message, its complete
code is like :
public class SoapMsgLogHandler extends GenericHandler {
private Logger soapLogger = null;
public void init(HandlerInfo config) {
soapLogger =
SubscriberDataMgrBindingImpl.baseContext.getCtxLog();
}
public QName[] getHeaders() {
return new QName[0];
}
private boolean logMessage(MessageContext
context, OutputStream out) {
if ((soapLogger != null) &&
(soapLogger.getLevel().toInt() <= Level.DEBUG.toInt()))
{
SOAPMessageContext smg =
(SOAPMessageContext) context;
try {
smg.getMessage().writeTo(out);
soapLogger.debug(out.toString());
} catch (Exception e) {}
return
true;
}
else
return false;
}
public boolean
handleRequest(MessageContext context) {
return logMessage(context,System.out);
}
public boolean
handleResponse(MessageContext context) {
return
logMessage(context,System.out);
}
I add it into the requestFlow of one service, I did
deploy it. However, while I was to invoke that service, I got SoapFault which
indicates following error
faultString: org.apache.axis.ConfigurationException:
java.lang.ClassCastException

Has anyone run into this kind of problem before ?
