Call EJB method from web services project - web-services

Question

I have a webservice project (WebServiceProject2) and I want to call a method in EJB project (BelsizeEJB).
I have done the following: Right-click WebServiceProject2 -> Build Path -> Configure Build Path -> Projects tab -> Add -> BelsizeEJB -> OK
Login.java in BelsizeEJB project
package com.belsize.module;
public class Login {
public boolean loginuser(String User, String Password) {
String LOC = "Login: loginUser";
System.out.println(LOC);
return true;
}
}
Authenticate.java in WebServiceProject2
package com.myeclipseide.ws;
import com.belsize.module.Login;
public class Authenticate {
public boolean doLogin_loginAction(String User, String Password) {
System.out.println("Testing Start");
Login _l = new Login();
System.out.println("Login Method Result: " + _l.loginuser(User, Password));
System.out.println("Testing End");
return _l.loginuser(User, Password);
}
}
After done the above mentioned, I had Create a new web service and generate the wsdl as followed:
Authenticate.wsdl
<wsdl:message name="doLogin_loginActionResponse">
<wsdl:part element="impl:doLogin_loginActionResponse" name="parameters">
</wsdl:part>
</wsdl:message>
<wsdl:message name="doLogin_loginActionRequest">
<wsdl:part element="impl:doLogin_loginAction" name="parameters">
</wsdl:part>
</wsdl:message>
<wsdl:message name="loginRequest">

</wsdl:part>
</wsdl:message>
<wsdl:message name="loginResponse">

</wsdl:message>
<wsdl:portType name="Authenticate_SEI">

</wsdl:operation>
<wsdl:operation name="doLogin_loginAction">

</wsdl:input>
<wsdl:output message="impl:doLogin_loginActionResponse" name="doLogin_loginActionResponse">
</wsdl:output>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="AuthenticateSoapBinding" type="impl:Authenticate_SEI">
<wsaw:UsingAddressing xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" wsdl:required="false"/>
<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="login">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="loginRequest">

</wsdl:input>
<wsdl:output name="loginResponse">
<wsdlsoap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="doLogin_loginAction">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="doLogin_loginActionRequest">
<wsdlsoap:body use="literal"/>
</wsdl:input>
<wsdl:output name="doLogin_loginActionResponse">
<wsdlsoap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="AuthenticateService">
<wsdl:port binding="impl:AuthenticateSoapBinding" name="Authenticate">
<wsdlsoap:address location="http://localhost:9081/WebServiceProject2/services/Authenticate"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
However when I try to invoke a wsdl operation, I encountered the following error:
[6/4/13 15:54:36:006 SGT] 000000b7 SystemOut O Testing Start

Much appreciate for your response.
Thanks.

Answer 1

The error message seems similar to this:
JAX-WS server-side SOAPHandler that returns fault gets "Internal Error" on WebSphere v8
According to IBM:
When webservices.unify.faults is set to "true", the runtime exception
thrown by the application code is unified, and the client will receive
a SOAP fault message indicating "Internal Error".
The fix for this APAR is currently targeted for inclusion in fix packs
7.0.0.25 and 8.0.0.4. Please refer to the Recommended Updates page for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Perhaps you could update your version of WebSphere to at least 8.0.0.4?
