JCO RFC provider: Server function not found, short dump

Question

Hi all,
I'm trying to use the JCO RFC provider service of NW04s (SP15) together with an ABAP 4.6C system. I've followed all the documentation that I could find, but couldn't get it to work yet. This is what I've done so far:
Using SM59 I've had a destination APP_JK1 created for me on the R/3 system. AFAIK it's set up correctly and marked as a "registered server", connection tests were successful.
On the portal, I've created a RFC portal destination using my R/3 credentials and successfully tested it. Then I created an entry in the RFC provider service, using the correct values for system, id & gateway, and let it point to my RFC destination for the repository connection. The program ID is also APP_JK1.
Next, I created a stateless session bean which is part of an EAR, gave it a JNDI name of "RFCTEST" and added a method like this:
    * @ejb.interface-method view-type="both"
    * @param function called function
   public void processFunction(com.sap.mw.jco.JCO.Function function) {
      JCO.ParameterList input  = function.getImportParameterList();
      String query = input.getString("I_STRING_SEARCH");
      JCO.ParameterList output = function.getExportParameterList();
      output.setValue(query, "ECHOTEXT");
(The project uses xdoclet for the creation of J2EE stuff)
In application-j2ee-engine.xml located in the META-INF directory of my EAR, I've added:
<reference reference-type="hard">
     <reference-target provider-name="sap.com" target-type="library">com.sap.mw.jco</reference-target>
</reference>
The application deploys without errors, and besides from my RFC connection works as expected. In the JNDI registry view of VisualAdmin I see the corresponding entry: "rfcaccessejb/RFCTEST" is a local reference to my stateless session bean.
On ABAP, I have a tiny little program that calls my function, mainly looking like this:
CALL FUNCTION 'RFCTEST' DESTINATION 'APP_JK1'
  EXPORTING
    I_STRING_SEARCH = query
  IMPORTING
    ECHOTEXT = t1.
Unfortunately, it short dumps immediately. The error message is:
JCO.Server could not find server function 'RFCTEST'
I'm lost. What could be wrong? Any help is greatly appreciated. Kind regards,

Hello Perry song,
You got the short dump bcoz, there is no perform by the name you provided in the program,
for example. consider there are 2 programs.
Program 1 :
REPORT  ZPGM1.
*Calling a perform SNAME1 , the code of perform is written in ZPGM2.
perform sname1 IN PROGRAM ZPGM2.
Program 2 :
REPORT  ZPGM2.
perform sname1 .
Form SNAME1 .
write : 'Text in form SNAME1' .
endform.                    " SNAME1
(here SNAME1 is found and it works perfectly )
Change in Program 1 :
REPORT  ZPGM1.
*Calling perform DELTA ,
perform DELTA IN PROGRAM ZPGM2 IF FOUND.
Now the perform statement will search for perform " DELTA " in ZPGM2 , but there is no perform by name DELTA , so here we need to mention the condition " IF FOUND "  , so now by mentioning the condition " IF FOUND " in perform statement ,  if the perform DELTA is not found then it wont go to DUMP.
If condition " IF FOUND "  is not mentioned in perform statement like
perform DELTA IN PROGRAM ZPGM2 . ( This gives DUMP )
just type " IF FOUND " when u r calling a perform from other program ( i guess this will solve the problem ).
Hope it might be helpfull,
Regards ,
Aby
