Call external service in a Application service created from ES

Question

Hi Experts
I have the follow situation:
I've modeled a new service in Enterprise Service Builder. This service i'll implement in caf application. In the method create by application i'll call one method of external service.
I imported this modeled service in Create Web Service Provider option in external package, select the Enterprise Service Repository source option and choice the respective Service Interface.
In this moment the caf created a new application service, with methods of modeled service. That's all right.
Now i import a external service of esworkplace. All the step are ok. But the problem is going to next step.
I need to call this imported service in the method of application service. I know 3 way to do this:
1. Mapping the external service with this application service. In this case i have a problem - the method of external service is expose as web service, and i don't want this. Just the method of modeled service must be expose.
2. Create another application service, map the external service with this application service, and create a depency between this application service and the application service created by modeled service. I think this work fine and resolve the problem of expose the method of external service. However i think this isn't a good way to do.
3. Instantiate the service class of exernal service. From this class i can call the method of external service in application service. But now i have another problem. If i see the implementation of this class, it have a static block which call a URL class, and pass as parameter a wsdl file located in one directory of my computer like
url = new java.net.URL("file:/D:/SAP7110Workspace.jdi/LocalDevelopment/CRVP/demo.sap.com//ejbmodule/
_comp/tmp/0/EJB/src/META-INF/xml/ext/rootwsdl_WorkCentreSimpleByPlantQueryResponse_InService.wsdl");
when execute the application in the server it don't find this file and i give one error.
I think the best way to do is the 3° way. But why did the caf generate the URL with My computer directory instead of in directory of application? There are some solution to this problem?
I've change this line manualy, but all the time when i generate the project, i need change this code again.

Hi,
You may consume external service via JNDI
Context context = new InitialContext();
<JNDI OBJECT> local = (<CAST JNDI OBJECT>)context.lookup("<JNDI OBJECT>");
//Call the method
If you are using CE 7.11, go to NWA -> Problem Management -> JNDI browser  > ..... -> ObjectName for <JNDI OBJECT>
