Hi Fredrik
Actually i'm making the inverse stuff. Providing a webservice via
axis/webobjects for clients
and not calling a webservice from within webobjects.
The difference between doc/lit/wrapped and doc/lit is that the
function name is within input/output element
(see discussion for example here.
http://atmanes.blogspot.com/2005/03/wrapped-documentliteral-convention.html)
I have no experience with using WOWebServiceClient classes, why do not
use axis directly? It is already
included in WebObjects and if you have access to the WSDL files you
can gemerate all the stubs to call the function
via wsdl2java.
in my ant task i make the following (assuming that all axis jars are
in lib and ${ws.name) is set
to the webservice name:
<target name="axis.clientbuild" description="build axis services">
<path id="axis.classpath">
<fileset dir="lib">
<include name="**/*.jar" />
</fileset>
</path>
<taskdef resource="axis-tasks.properties" classpathref="axis.classpath" />
<axis-wsdl2java output="Sources" verbose="true"
url="${ws.name}.wsdl" testcase="true">
<mapping namespace="http://xxx.xx.xx/${ws.name}/";
package="xx.xxx.xx.${ws.name}" />
</axis-wsdl2java>
</target>
and then you have even a junit testcase which invokes the service.
if you go the axis way i would suggest that you read the axis tutorial
at http://ws.apache.org/axis/java/user-guide.html. axis tcpmon just as
a standalone tool is very helpful for debugging whats going on the
soap wire ... if you use the service
like this i don't think you need to make any changes except you run
java5 which might fail with older axis versions.
