Hi ALL,
im using SOAP message to build MM7 message,
i have a soap connection that create a connection to a servlet tp process request,
the response is a soap message with attachment.....
the SOAP is 1.1.
SOAPConnectionFactory connf = SOAPConnectionFactory.newInstance();
SOAPConnection conn = connf.createConnection();
SOAPMessage sMessage= conn.call (soapMessage, "http://190.0.0.16:8988/mmsc/httpReceiver");
sMessage.writeTo(output);

Answer 1

Hello,
The easiest way to call a Web Service is to use a Client Library instead of calling the SOAP call yourself.
Can you for your project use a Web Service client stack (JAX-RPC, Axis, XFire, ...) this will create from the WSDL file a set of class and give you a very simple caller class that you can then integrate to your JSP.
I am pointing you to the OracleAS Web Service Documentation section about Web Service proxy.
And some simple how-tos that have specific tasks to create client:
- Web Servics How Tos
So you can see this specific ant target to create a WS proxy:
<oracle:genProxy wsdl="[your URL to a WSDL]"
output="${src.cli.dir}"
packageName="bottomup.client.proxy"
>
<classpath>
<pathelement path="${bld.cli.dir}"/>
<pathelement location="${ORACLE_HOME}/webservices/lib/wsa.jar"/>
</classpath>
</oracle:genProxy>
