Pls suggest how to resolve this.Is this related to Version mismatch of support packs.
I have checked the Jco RFC.All are working fine.

Hi Ajay,
I am facing the same issue and am trying to follow the note that you had suggested. The note says to create the dummy RFCs "PT_ARQ_ACCOUNTS_GET_CE", "PT_ARQ_REQLIST_GET_CE" and PT_ARQ_READ_CE_SWITCH, But doesn't say which package I should save the RFC/structures/table types in. I tried saving them in EA-HR, but got the following error. "EA-HR cannot be extended."
Please help.
Regards,
JS.

Error in BPM: "COMMUNICATION FAILURE" during JCo call. Error opening an RFC

hello experts
i am receiving the above error incase of BPM scenario where i am having a Transform step and synchronous RFC step.
i referred to the few threads discussing such problems and was trying to find whether my mapping is correct and i tested my mappings using my payload which looks good.
When looked into the Mapping trace of the BPM "Show container" i found error ""COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection" and it seems that when BPM is attempting to call interface mapping it is throwing this error.
Thanks in advance.
Regards
rajeev

hi,
I think no problen with the mapping part,

JCO RFC provider: Server function not found, short dump

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,
Christian Aust

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

Hi Ahmed,
Please do check the validity of the certificate.
Please do cross check these steps again.
1.     Transaction u2013 STRUSTSSO2 (Trust Manager for Logon Ticket)
2.     Double Click Owner certificate. It gets reflected under the certificate tab.
3.                  Choose Format Binary
4.                  Choose File Path.
5.                  Enter the File Name
6.                 saved in local drive.
You can import into portal as x.509 certificate.
check this thread -
Certificate no longer has signature (use restriction)
Renew certificate via SAP MarketPlace, and install from tcode slicense. If you are working on a trial version, there is a SAP license request application form. Fill the form with the hardware key. you will get the new license via email. Install using slicense. Then try exporting the certificate.

Error while loading service JCo RFC Provider

When I click on the "JCo RFC Provider" node under services in Visual administrator, I get an error:
"Error while loading service JCo RFC Provider"
Does anyone know what has gone wrong here, and how I go about fixing it?
Thanks in advance
Regards
Richard
PS. We're using EP6sp14

You have to use the correct Visual Admin version:
if your netweaver is 6.40 use VA 6.40 ... and for 7.00 the same, VA 7.00
(you get them from OS where netweaver is installed)
other possiblity: use Administrator login and check if it works, then correct your permissions (mostyl 'Administrators' group is missing)

JCO RFC Provider: "Bean not found" when calling EJB from ABAP via RFC

Hello,
I'm having trouble calling an EJB in a CE 7.1 system from ABAP via RFC. I'm trying to use the JCO RFC Provider service, which mean that I want to expose an EJB so that it can be called via Remote Function Call.
I have documented everything, including the code and the deployment descriptors I wrote, in this thread in the CE forum: Jco RFC Provider: Bean not found
If there's any chance you can help, please do me a favour and look into the problem.
Thanks a lot!

Hi Vladimir,
Thank you very much, your help was immensely valuable.
I just had to add the function declaration to the Home Component interface, everything else was correct, and now it works.

Error msg-Adaptive RFC reimport could lead to inconsistency of R/3 metadata

Hi Experts,
I am trying to reimport the model for Webdynpro application.
I wanted to include more BAPIs to the existing model.
When i am trying to do that I get pop up, with following message;
"Adaptive RFC reimport could lead to inconsistency of R/3 metadata cached on J2ee server.
Thus it is recommended to invalidate the cache this could be done either by re starting the J2EE server or by using adaptive RFC metadata cache invalidatation tool within webdynpro Console"
Could anyone one help me in resolving this?
Thanks and regards,
Pradnya

Hi,
When you reimport an RFC/BAPI the metadata which is stored in the cache is not cleared. So it still refers to the old RFC/BAPI metadata. We need to clear this. This can be done by either restarting the server or webdynpro console.
For Clearing through webdynpro console the version should be NW04 or 6.40 SP21 Onwards 2. NW04S or 7.0 SP12 Onwards
Check this link.

Third party system (JCO) ---RFC--- PI ---RFC--- ECC

Hello all,
We are trying to implement the following scenario:
Third party system (JCO) -RFC-> PI -RFC-> SAP ECC
The third party system connect to PI via Java Connector API with a know user id in PI. After that third party system tries to obtain the RFC that is already implemented and remote enabled in SAP ECC environment. But at this step there is something wrong in third party system software because we are not able to obtain the RFC interface and metadata from PI repository.
1. This step is working correctly. Connection is OK.
            JCO.Client mConnectionPI = JCO.createClient("100", // SAP client
                                                                                "user_id", // userid
                                                                                "********", // password
                                                                                "pt", // language
                                                                                "10.x.x.x", // application server host name
                                                                                "01"); // system number
            mConnectionPI.connect();
2. This step is not working correctly:
            JCO.Repository repository = new JCO.Repository("TestRep", mConnectionPI);
            IFunctionTemplate ftemplate = repository.getFunctionTemplate("Z_RFC_XXX"); - not found exception
We would like to know if there is something missing in any environment that we have to configure or implement in order to fix this issue. Thanks a lot.

Hi Primini,
couple of stupid-but-necessary questions:
1) have you imported the RFC model in PI Repository?
You don't need to have the RFC metadata in PI ABAP stack (there is no point in doing that), but rather in the PI Repository/ESR, within the SWCV you've created.
Check the "Activities" session of this link for more details:
http://help.sap.com/saphelp_nw70ehp2/helpdata/en/2b/a48f3c685bc358e10000000a11405a/frameset.htm
2) if you have done 1), have you configured the RFC Sender scenario properly?
I mean, have you ran the configuration wizard to create the agreements & determinations, setting the RFC interface as both the sender and the receiver interface? Of course, the systems would be different: as the sender system, you'll have a Business Service representing the legacy/JCo system; as the receiver, you'll have the ERP Business System.
This should make your scenario work.
If it doesn't, try one more thing: in the JCo code, just for the metadata repository connection, use a connection to the ERP system. But for the actual call, use the PI system.
Let us know the results.
Best regards,
Henrique.

LCRSAPRFC is missing in Visual Admin (JCo RFC Provider)

H y,
I'm facing a problem while connecting our SolMan via RFC to SLD.
Found documents explainig how to set up connection to SLD.
SAPSLDAPI (was present in Abap and Java - wrong credentials - repaired)
LCRSAPRFC (only present as RFC CONN in ABAP, but missing in Java, Visual Administrator JCo RFC Provider
How can be the LCRSAPRFC added to JCo RFC Providers?
Do I have to create the RFC Conn LCRSAPRFC again in Abap/SM59 to get the LCRSAPRFC visible again in Visual Admin?
Thanks in advance
Tom

Hi,
Do I have to create the RFC Conn LCRSAPRFC again in Abap/SM59 to get the LCRSAPRFC visible again in Visual Admin?
Not Required.
LCRSAPRFC (only present as RFC CONN in ABAP, but missing in Java, Visual Administrator JCo RFC Provider
Usual Process
Maintaining the RFC Connections (Transaction SM59)
1. Log on to your SAP Exchange Infrastructure central instance host.
2. Call transaction SM59.
3. Choose Create.
4. Enter at least the following:
RFC destination:LCRSAPRFC
Connection type: T
Description: <your description>
5. Choose ENTER
6. Choose the tab Technical settings and do the following:
a. Select Registered Server Program
b. In the Program ID field, enter: LCRSAPRFC_<SID>
where <SID> is the SAP system ID of your Integration Server host.
Use uppercase letters only.
c. Enter Gateway host and Gateway service of your Integration Server host.
To find out the required parameters:
a. On the Integration Server host, call transaction SMGW
b. Choose Goto u2192 Parameters u2192 Display (see entries for gateway hostname and
gateway service)
7. Choose tab Special Options and select the flag Unicode in the box Character Width in
Target System.
8. Save your settings.
Java Stack
SAP J2EE Configuration for the Destinations (Visual Administrator)
1. On your SAP Exchange Infrastructure central instance host, start the SAP J2EE
Engine administration tool.
If you do not know how to start, see section How to start the SAP J2EE Administration Tool .
2. Choose Cluster u2192 Server u2192 Services u2192 JCo RFC Provider
3. In the section RFC destination, enter exactly the same program ID and gateway options for LCRSAPRFC that you used in the step Maintaining the RFC connection above.
Additionally, set the number of processes to 3.
4. In the section Repository, do the following:
a. Enter the parameter for the SAP XI host: Application Server, System Number, Client
and Language.
b. For User and Password maintain the login parameters for the user SAPJSF.
c. Select the flag Unicode.
6. Choose Set.
Testing
After you have maintained an RFC destination in both the ABAP and Java environment,
you can check it as follows:
1. Call transaction SM59 again.
2. Open your RFC destination.
3. Choose Test Connection.
No error should be displayed.

How to handle JCO Exceptions at JCO (RFC) function call

Hello Forum,
I am implementing an JCO Server scenario.
I use dynamic repositories like Example7.java from the JCO documentation.
Example7 throws an JCO.AbapException if anything went wrong, e.g. the function is not implemented.
How to react on this AbapException?
The examples in SAP Help documentation only catch
SYSTEM_FAILURE and COMMUNICATION_FAILURE.
All other RFC modules I have seen which declare the function modules to be used by dynamic JCO repositories (like Example7.java) do not define any other Exception parameters.
But these two are only thrown and caught when something with communication went completely wrong, e.g. RFC not found.
But when RFC can be reached and the JCO Server is executing the Java method, an AbapException could be thrown on error. How to react on this?
In my implementation based on the examples I always get a ABAP dump. The dump says:
Exception named without message text. Why that name?
How to handle this type of exception in order to avoid the dump?
Can anyone post an example please?
Thanks,
Carsten

Hi Micky,
thanks for your quick response.
If so, to throw JCO.AbapException on JCO Server side is not correct?
What I do is throwing the JCO.AbapException (like in the JCO Example 7).
At the RFC call in APAB I handle both exceptions SYSTEM_FAILURE and COMMUNICATION_FAILURE like
CALL FUNCTION 'MY_JCO_FUNCTION_MODULE'
    DESTINATION JCO_DEST
    <...>
    EXCEPTIONS
      SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
      COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
This works as far something with RFC is wrong, e.g. Server can not find the function or Server not reachable.
But the AbapException thrown by the JCO Server (Java) is not handled that way. Why?
Sorry if this is the wrong forum but I tried posting in Netweaver integration and got no answer for 1 week and because it's ABAP related I thought the topic suites here.

JCO RFC Provider problem

Hi!
We are having some problems in 2 PI 7.1 SP7 Development and Project
systems. Both have the same problem... We cannot see JCO RFC Provider
connections and we cannot create new JCO RFC connections.
Our Project system is copy of development and JCO connections are being
registered on Development causing some problems in proxy connections.
the problem is that we cannot change the JCO RFC connections on both
systems.
If I try to create a new JCO RFC Connection or even a dummy JCO connection it gives the error "The Program ID already exists. Type in an other name."
These systems are a SAP PI 7.1 upgrade from SAP XI 3.0. In version XI 3.0 the connections were OK.
In quality Assurance and Production we don't have this problem.
I've applied the latest AS Java patches but didn't changed the strange behaviour.
Have any one notice

In the default trace file we've found something like
"com.sap.engine.services.jmx.exception.JmxSecurityException: Caller <(>
<<)>some generated user id> not authorized, required permission missing"activate the UME super user, delete the deleted users, deactivate the UME super user and restart the system.
For further information you should see note 1261071

Error:No Jco RFc metadata found
