NameNotFoundException: Name comp/env/service not found in context "java:".

I have to create a portlet that access a Remote Web Service. I've created a Portlet Project on WSAD 5.1.2 with Portal Toolkit 5.0.2.3 and later I've imported a ".wsdl" file to have the definition of Web Service. In this ways I've generated the the proxy
/client classes with right click - Web Services - Generate Client Option of WSAD.
When I install the portlet on WebSphere Portal 5.0 and execute one of the methods of the proxy class I get this Error:
javax.naming.NameNotFoundException: Name comp/env/service not found in context "java:".
The Proxy class throws an exception on this sentence:
javax.naming.InitialContext ctx = new javax.naming.InitialContext();
procesoSeleccionSoap = ((org.tempuri.ProcesoSeleccion)ctx.lookup("java:comp/env/service/ProcesoSeleccion")).getProcesoSeleccionSoap();
The error occurs on this part of sentence:
ctx.lookup("java:comp/env/service/ProcesoSeleccion")
Why can I do? I have to define "service/ProcesoSeleccion" on any xml configuration file? WSAD has been generated all xml configuration files that are necessary, I supose.
I have created a Web Service Project with the same and runs ok! What's the problem of portlet?

Yes! ProcesoSeleccion is the name of WebService. I'm a junior developer on WebSphere Portal and portlets, but I cannot understand why does not work, if exist a web service project that has been generated from wsdl file and wotks fine, why if I do the same
in portlet project doesn't works correctly! I think that int Web Service project config xml files like 'webserviceclient.xml','ProcesoSeleccion_mapping.xml','ibm-webservicesclient-bnd.xml','ibm-webservicesclient-ext.xml' are loaded correctly on runtime b
ut in WebShpere Portal this xml config files are not the same, but I don't know nothing about that.
On the other hand, I can modify proxy class changing value of _useJNDI property to false and then proxy class tries to create a ProcesoSeleccionLocator (extends com.ibm.ws.webservices.engine.client.Service and use a default constructor! Only adds 2 method
s, no change nothing!) and I get this other error:

YOU CAN SEE THE CODE HERE! THIS IS A METHOD GENERATED FOR WSAD AND THIS IS CALLED ON PROXY CONSTRUCTOR!
