Hi all! I am currently working of following scenario:
I have deployed a service to Axis beta1 (running on tomcat 3.3) that returns a Long object. Additionally, I defined request and response handler on server side that simply output a message to the console. I used following wsdd file to deploy the service: <deployment xmlns="http://xml.apache.org/axis/wsdd/"; xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";> <handler name="TestRequest" type="java:TestRequestHandler"/> <handler name="TestResponse" type="java:TestResponseHandler"/> <service name="TestService" provider="java:RPC"> <parameter name="className" value="TestService"/> <parameter name="methodName" value="*"/> <requestFlow> <handler type="TestRequest"/> </requestFlow> <responseFlow> <handler type="TestResponse"/> </responseFlow> </service> </deployment So far this works fine. Additionally, I would like to call the same request and response handlers on client side. For this, I created a client-config.wsdd based on the above deployment file (used org.apache.axis.utils.Admin client). When I now call the client progam, i get a null pointer exception in the invoke method of the call object (See stack trace). I simply put the client-config.wsdd file in the directory were I start my test driver. java.lang.NullPointerException: at java.util.Hashtable.get(Hashtable.java:320) at org.apache.axis.utils.cache.JavaClass.getMethod(Unknown Source) at org.apache.axis.message.RPCElement.deserialize(Unknown Source) at org.apache.axis.message.RPCElement.getParams(Unknown Source) at org.apache.axis.client.Call.invoke(Unknown Source) at org.apache.axis.client.Call.invoke(Unknown Source) at org.apache.axis.client.Call.invoke(Unknown Source) at TestDriverRemote.main(TestDriverRemote.java:41) My code works fine, if i don't use the client-config.wsdd file. When I use tcpmon to track the messages between client and server, I see a valid response message sent back to the client. The implementation of the request / response handlers only checks whether the handler is called on client side or not ( msgContext.isClient() ) and prints a respective console message. Later, I would like to do some encryption and decryption in these handlers. Has anybody experienced the same problems and found a solution? Any help would by highly apprechiated! regards Klaus
