Solved: Java Proxy Error - SystemFaultException

Former Member · ‎11-17-2008

I am using PI 7.1, Client Java proxy<~~>SAP PI <~~> RFC

Here is my Client Java Proxy Class:

public String InvokeJP(String sReq)

{

String ret = "";

SIConnectJP_PortTypeHome queryOutHome;

SIConnectJP_PortTypeRemote queryOutRemote;

// check for EJB class on server

try

{

Properties prop = new Properties();

prop.put(Context.PROVIDER_URL,"devPI:50104");

prop.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");

prop.put(Context.URL_PKG_PREFIXES, "com.sap.engine.services");

InitialContext ctx = new InitialContext(prop);

String ctxPath = "ejb:/appName=sap.com/SI_ConnectJPEAR,interfaceName=com.Test.jPR2SAP.SIConnectJP_PortTypeHome";

queryOutHome = (SIConnectJP_PortTypeHome)ctx.lookup(ctxPath);

queryOutRemote = queryOutHome.create();

} catch (Exception e) {

System.out.println("RemoteException occurred: "+e.getMessage());

e.printStackTrace();

return "<"e.toString()">";

}

// Call the Java proxy and get the return parameters

try {

// Get Remote interface

MessageSpecifier msg = queryOutRemote.$messageSpecifier();

msg.setSenderService("BS_JPR_SAP");

queryOutRemote.$messageSpecifier(msg);

//Set Request

DTReq_Type dt_req = new DTReq_Type();

dt_req.setReqPayload(sReq);

//Get Response

DTRes_Type dt_res = new DTRes_Type();

//Remote

dt_res = queryOutRemote.sIConnectJP(dt_req);

//Set Response

String sResponse = dt_res.getResPayload();

ret = sResponse;

return ret;

}

// Handle fault exception

catch (java.rmi.RemoteException e) {

System.out.println("RemoteException occurred: "+e.getMessage());

e.printStackTrace();

return "<RemoteException occurred:"e.toString()">";

}

catch (com.sap.aii.proxy.xiruntime.core.ApplicationFaultException e)

{

System.out.println("ApplicationFaultException occurred: "+e.getMessage());

e.printStackTrace();

return "<ApplicationFaultException:"e.toString()">";

}

catch (com.sap.aii.proxy.xiruntime.core.SystemFaultException e)

{

System.out.println("SystemFaultException occurred: "+e.getMessage());

e.printStackTrace();

return "<SystemFaultException:"e.toString()">";

}

catch (Exception e)

{

System.out.println("Undefined Exception occurred: "+e.getMessage());

e.printStackTrace();

return "<Undefined Exception occurred:"e.toString()">";

}

Error while invoking client Java Proxy class:
