从web服务项目调用EJB方法

Question

我有一个web服务项目(WebServiceProject2)，我想在EJB项目(BelsizeEJB)中调用一个方法。

我做了以下工作: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;
    }
}

authentication .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);
    }
}

完成上述操作后，我创建了一个新的web服务，并生成如下wsdl:

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

    </wsdl:part>
  </wsdl:message>
   <wsdl:portType name="Authenticate_SEI">
     <wsdl:operation name="login">
       <wsdl:input message="impl:loginRequest" name="loginRequest">
    </wsdl:input>
       <wsdl:output message="impl:loginResponse" name="loginResponse">
    </wsdl:output>
    </wsdl:operation>
     <wsdl:operation name="doLogin_loginAction">
       <wsdl:input message="impl:doLogin_loginActionRequest" name="doLogin_loginActionRequest">
    </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">
         <wsdlsoap:body use="literal"/>
      </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>

然而，当我试图调用wsdl操作时，我遇到了以下错误:

SOAP响应信封:

非常感谢您的回复。谢谢。

Answer 1

错误信息如下:

返回错误的JAX-WS服务器端SOAPHandler获取"内部错误";在WebSphere v8上

根据IBM:

当webservices. unity .faults设置为"true"时，运行时异常由应用程序抛出的代码是统一的，并且客户端会接收到一个SOAP错误消息，指示"内部错误"。

这个APAR的修复是当前包含在修复包中的目标7.0.0.25和8.0.0.4。有关交付信息，请参阅"推荐更新"页面:http://www.ibm.com/support/docview.wss?rs=180& uid = swg27004980

也许您可以将WebSphere的版本至少更新到8.0.0.4?
