Subject: Re: How to get the SOAP
Envelope from msg Context without invocation
Jose,
You wont be able to get a SOAPEnvelope at the
client end after the call or before the call .. because before the call
there is no SOAPMessage and after the Call the response is over.
and Call.getMessgaeContext() will return a null
value. So you cant access that Message Context.
How ever you can do one thing.
You can implement a Handler which will be invoked
only in the requestFlow and can then manipulate the SOAPMessage and the
Handler end.
To do that you must add a handler in the
deploy.wsdd file and write a Handler class which extends the BasicHandler
class of Axis APIs.
<handler name="AttachmentHandler"
type="java:com.bt.oexgateway.webservices.AttachmentHandler"/>
<service name="TestOAGXMLService" provider="java:RPC" style="rpc"
use="encoded">
<requestFlow>
<handler type="AttachmentHandler"/>
</requestFlow>
<responseFlow>
<handler
type="AttachmentHandler"/>
</responseFlow>
....
</service>
The handler class will be something like this
import
org.apache.axis.handlers.BasicHandler;
public class AttachmentHandler extends
BasicHandler
{
public void invoke(MessageContext msgContext)
throws AxisFault
{
System.out.println("Hi Hi
Handler Invoked !! ");
// Gets the
Request SOAP Message
Message reqMsg =
msgContext.getRequestMessage();
// Gets the response
SOAP Message
Message respMsg =
msgContext.getResponseMessage();
...
....
}
}
During the call from the client the method invoke()
of the declared handler is called . It depends on the declaration in the
WSDD file . If you need it in both requestFlow and responseFlow then
give as above wsdd. if you need only in request then only
<requestFlow> is needed.. Depends upon you and ur
application.
People, Hope I am right here.
Hope this helps you
Cheers

Subject: How to get the SOAP Envelope
from msg Context without invocation
Hi:
I'm
writing an Axis Client that needs to send RPC style signed
requests
according to XML-DSIG. My problem is that in order to sign the
SOAP Envelope
I need to first have it! :-) I have looked everywhere but
I haven't found
where to do this.
I'm doing
Service
service = new Service();
Call call = (Call)
service.createCall();
call.setTargetEndpointAddress( new
java.net.URL(endPoint) );
call.setOperationName( new QName(endPoint,
operationName) );
call.addParameter( "String", XMLType.XSD_STRING,
ParameterMode.IN );
call.setReturnType( XMLType.XSD_STRING );
String
resu = (String) call.invoke(new Object[] { "Some String Input"
});
After this last statement I can get the SOAP Message from the
message
context doing:
mc = call.getMessageContext();
env =
request.getSOAPEnvelope();
But the service was already invoked!!!Is
there any way of setting the
parameters used for a call without
actually invoking the service?
Cheers,
Jose M
