I am having a problem retrieving the SOAP Response in the Response Flow as
explained below:
a) I have simple HelloWorld RPC Service:
package com.myclasses;
public class HelloWorld {
public HelloWorld() {
}
public String sayHelloWorld(String name) {
return "Hello World to " + name;
}
}
b) I have defined a couple of handlers that intercept the request flow and
response flow. The WSDD file for HelloWorld Service is shown below:
<deployment name="SparePartInfo" xmlns="http://xml.apache.org/axis/wsdd/";
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";>
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance";>
<!-- Define the Request Handler i.e. SOAPRequestLogger -->
<handler name="SOAPRequestLogger"
type="java:com.myclasses.SOAPRequestLogger">
<parameter name="SOAPLogFile" value="d:\\SOAP.log"/>
</handler>
<!-- Define the Response Handler i.e. SOAPResponseLogger -->
<handler name="SOAPResponseLogger"
type="java:com.myclasses.SOAPResponseLogger">
<parameter name="SOAPLogFile" value="d:\\SOAP.log"/>
</handler>
<!-- Define the Service (HelloWorld) -->
<service name="HelloWorld" provider="java:RPC">
<requestFlow>
<handler type="SOAPRequestLogger"/>
</requestFlow>
<responseFlow>
<handler type="SOAPResponseLogger"/>
</responseFlow>
<parameter name="className" value="com.myclasses.HelloWorld"/>
<parameter name="allowedMethods" value="sayHelloWorld"/>
</service>
</deployment>
c) In my SOAPRequestHandler defined in the requestFlow of the service, I
have the following code in the invoke(MessageContext ctx) method
.......
Message reqMessage = messageContext.getRequestMessage();
SOAPPart soappart = reqMessage.getSOAPPart();
SOAPEnvelope env = soappart.getAsSOAPEnvelope();
Element envElement = env.getAsDOM();
String strSOAPRequest = XMLUtils.ElementToString(envElement);
//Log strSOAPRequest into File (CODE NOT SHOWN)
.......
d) In my SOAPResponseHandler defined in the responseFlow of the service, I
have the following code in the invoke(MessageContext ctx) method
.......
Message resMessage = messageContext.getResponseMessage();
SOAPPart soappart = reqMessage.getSOAPPart();
SOAPEnvelope env = soappart.getAsSOAPEnvelope();
Element envElement = env.getAsDOM();
String strSOAPResponse = XMLUtils.ElementToString(envElement);
//Log strSOAPResponse into File (CODE NOT SHOWN)
.......
If I run a client for the above service, WITHOUT the <responseFlow> element
for the <service>, everything is fine and the SOAP Request is logged
correctly in the file.
If I run a client for the above service, WITH the <responseFlow> element for
the <service>, I get the following error:
---------------
java.io.IOException: No serializer found for class java.lang.String in
registry org.apache.axis.encoding
.SerializationContextImpl@4cf67
---------------
I traced the problem to the getAsDOM() method on the SOAPEnvelope class. Why
is the getAsDOM() failing at this point ? Any clues ???
Any pointers will be appreciated :-)
Thanks
Romin.
