In short: wsdl2java produces duplicate copies of my JavaBean classes,
but using a generated (different) package name.
Hi,
In an effort to learn web services + axis, I wrote a simple standalong
java-client - to - web service app. The idea is that Client uses
JavaBean classes to display some info and do some work, it also uses
those beans as input args to the Web Service; and Service uses those
same JavaBeans as return params. The package structure of my app is as
follows:
computeservice.beans - contains two JavaBean classes (InputValue, and
OutputValue) used throughout client and server classes to do internal
work, also used as args/return types with web service.
computeservice.service.ComputeService - server side class. Methods of
these classes are exposed as web service operations (using WSDL file)
computeservice.client.ServiceClientApp - client side standalone app,
accumulates user input into InputValue, passes InputValue as arg to web
service operation, gets OutputValue in return, displays that locally.
I'd like to distribute this app in two packages: .WAR file for
server-side deployment, and a .JAR for desktop java client app. It is my
understanding that I should package computeservice.beans into both
archives, since both .client and .service classes use them.
Here's the problem:
On the server side, SEI defines operation:
public computeservice.beans.OutputValue
doMultiply(computeservice.beans.InputValue inputValue)
When I use wsdl2java to generate client-side classes necessary to talk
to the service, InputValue and OutputValue are also generated (even
though I already have them computeservice.beans). But their package
names are incorrect:
"package ComputeServiceWS;
public class InputValue implements java.io.Serializable {...."
(similarly OutputValue)
public ComputeServiceWS.OutputValue
doMultiply(ComputeServiceWS.InputValue inputValue_1) throws
java.rmi.RemoteException;
This precludes the following from working in my standalone app:
computeservice.beans.InputValue inputFromUserGUI = gui.getInput();
computeservice.beans.OutputValue retValue =
service.doMultiply(inputFromUserGUI); //this won't work, as service
expects ComputeServiceWS.InputValue,
not computeservice.beans.InputValue, and I can't just cast one to another.
gui.displayOutput(retValue);
//declaration
public void displayOutput(computeservice.beans.OutputValue)
Here are my questions:
-How did wsdl2java decide on package name "ComputeServiceWS" for
InputValue/OutputValue instead of computeservice.beans?
-Since I already have source code for InputValue and OutputValue
included with client, any chance of precluding wsdl2java from generating
these classes (avoid code duplication)?
-If generation of InputValue and OutputValue source is inevitable, can I
force wsdl2java to produce correct package names. Or is that a setting
in WSDL file itself?
Ant task used to produce stubs:
<!-- generate WS stubs -->
<target name="gen-ws-client">
<axis-wsdl2java
output="scratch"
testcase="true"
verbose="true"
url="http://localhost:8081/ComputeWeb/ComputeServiceWS?WSDL"; >
</axis-wsdl2java>
</target>
I'm attaching some relevant files.
thanks a lot,
