JcoProxyRuntimeException when creating proxy object

[former_member673030]

Hi,

I am using the SAP J2EEEngine 6.20 and "Java Connectivity Builder Tool" because i want to call BAPIs on R3.

I want to call the SUSR_LOGIN_CHECK_RFC function, so i generate the java proxy code for that and i build and deploy my project correctly.

The problem is that i have got this runtime exception :

java.lang.ExceptionInInitializerError: com.sap.aii.proxy.framework.core.JcoProxyRuntimeException: Fault message cannot be instantiated

        at com.sap.aii.proxy.framework.core.JcoBaseProxyDescriptor.(JcoBaseProxyDescriptor.java:80)

I am using the Java Connectivity Builder Tool to generate proxy classes and my function that is called is:

public String checkLogin(String name, String pwd, JCO.Client myJco) {

  if (myJco != null) {

   try {

    Susr_Login_Check_Rfc_Input inp = new Susr_Login_Check_Rfc_Input();

    SusrBapi_PortType proxy = new SusrBapi_PortType();

    inp.setBname(name);

    inp.setPassword(pwd);

    proxy.messageSpecifier.setJcoClient(myJco);

    Susr_Login_Check_Rfc_Output out = proxy.susr_Login_Check_Rfc(inp);

   }

   catch(Exception ex) {

    return ex.toString();

   }

  }

  else {

   return "KO: myJco is null";

  }

  return "OK";

}

I have got this error when creating SusrBapi_PortType proxy = new SusrBapi_PortType();

If I try with another function like BAPI_USER_GET_DETAIL , it's ok

Do you have an idea of what is wrong ?

Hi Christophe,

as this is a support problem for a running system, first let me tell you that this is something for OSS.

Nevertheless, what I can tell you is that it seems you'r uising a BAPI that should log you in. If you have done the right configuration, this should have happened already. There is a large example for this in the Document "Working with Java SErver Pages and Servlets", that currently only is available in SAPNet. I'll try to bring it to SDN.

Regards,

Benny
