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)

Error while loading service Document Services Configuration (NW 7.0 SP13)

Hello,
I'm in the process of configuring the Adobe Document Services. Now I've received the Certificate + Credentials from SAP which I requested as described in Note 736902. I try to install them according to the Adobe Document Services Configuration Guide which I've downloaded from https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/90355269-4d89-2a10-0bb9-f388704f1dcd. [original link is broken] I've copied the pfx File to /usr/sap/<SAPSID>/SYS/global/AdobeDocumentServices/TrustManagerService/trust/credentials.
Then I started Visual Administrator and opened Server <x> → Services → Document Services Configuration. Here I get this Error returned:

Hi Nigel,
thanks a lot - I can now access the SLD data supplier from my local visual admin- great!
unfortunately, the key storage service still throws the error:

Error while loading services: Failure in Loader: VerifyError: Error #1014

I have a library that, after it loads, I see this error in the console:
Failure in Loader: VerifyError: Error #1014: Class mx.collections::ArrayCollection could not be found.
I had the same problem with another library, except it had a problem with IToken. I got around this problem by changing the default linkage of libraries in build path from external to merge into code. That did not work this time.
Merging Flex libraries into service libraries does not seem to be anything close to the correct way to deal with this. Besides, it didn't some the problem every time.
What is the best way to keep these sorts of dependency errors from arising? The RSLs are included with Web apps, but not with libraries.

I have found what happened.
I created a library and created a data model within it. I created some entities within the data model. Some of those entities had collections as properties. I created the ActionScript code for the model and the collections were ArrayCollections. I moved the interfaces of the created code to a separate library.
The interfaces need to be changed from using ArrayCollection to IList. I knew enough about that to change it for the service I was trying to bring into my application. I missed another interface that had ArrayCollections as properties and that caused the error.
After cleaning up all of the ArrayCollection references from the interface library my service loaded.
The Hello Gravity video tutorial has a very good explanation on why specific implementations of Flex classes are not used in service interfaces: http://blogs.adobe.com/gravity/2011/09/09/hellogravity-sample-application/

JCO RFC provider and JCO connection

Hi all:
Please share your thoughts on the following doubts I have. Thanks.
1. To my understanding, we use JCO RFC provider(define in Java side) and RFC destination(in SM59) when we have request from ABAP to Java side. Then we use JCO destinations(define in Web Dynpro Content Admin) if we have request from Java to ABAP. Is this correct?
2. When creating the JCO RFC provider service, why we need to create those entries for repository for example, the server name, the user used to log into repository? What is the repository used for?
Thanks!

Hai,
your understanding of JCO RFC and RFC Destination is right.But JCO Destination gets the metadata and model data from ABAP,thats what we mention the Dictionany meta data and Application data while creating them.
Yes, we need to mention the application host,sys no,client and userdetails while creating the JCO RFC provider,then only it will fetch the data from that host and that particular client.
Thanks and Regards,

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.
Thanks,

JCo RFC Provider Service

Hello
This topic may be not relevant to this forum but has anyone used JCo RFC Provider service for maintaining RFC Destinations?
What I am trying to do is to store the RFC Destinations over here and have a lookup on JCo RFC Provider service (or on its program id) from mapping tool.My code looks like
javax.naming.Context ctx = new InitialContext();
ctx.lookup("JCo RFC Service"); or
ctx.loopup("Program id name");
But while testing it gives Object Not Found exception.
I am expecting it to return JCO object which I can use to connect to SAP for executing RFCs.
Thanks in advance.
Regards
Rajeev

Hi rajeev,
Did u check if the Prog Id mentioned in JCo RFC provider is running (started in visual admin).
Did u perform ur lookup properly
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
p.put(Context.PROVIDER_URL, "server:50004");
p.put(Context.SECURITY_PRINCIPAL, "Administrator");
p.put(Context.SECURITY_CREDENTIALS, "password");
javax.naming.Context ctx = new InitialContext();
ctx.lookup("JCo RFC Service");
Hope this helps you.
Cheers,
Siva Maranani.

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.

Error While loading into BW using infoPackage

Hi All,
While following directions posted at the following wiki page https://wiki.sdn.sap.com/wiki/display/BOBJ/ConfiguretheLoadJobinBW%28DS+3.2%29,
we get an error while loading data into BW using infoPackage via Data services 3.2
In SAP BI side Error says :"Error while executing the following command: -sJO return code:220"
On DS side for the RFC server log we get the error" Error while executing the following command -sJOB_SQL_TO_DBI -Ubbu -P;(encrypted password) -A (encryted information) -VMODE=F"
Issue is still open with support as we still cannot excute the job from infopackage. it is succesfully executed from designer, admin console, batch file.
Any insights/help would be appreciated.
Thanks.
Edited by: rana_accn on Jan 26, 2010 6:48 PM

Sure I will.
One thing we have noticed is that in the server_eventlog parameter for the log line "Starting job with command line parameters are different"
When job is executed from DS side parameters -Ct -Cm -Ca -Cj -Cp -S -N -Q -U -P -G -r -T -Locale are used
When job is executed from BW side parameters -Ct -Cm -Ca -Cj -Cp -s -N -Q are used
Also when the job is executed from BW, log files start getting created but then trace and error file show an error that cannot open database - and that points to DSCentral repository.This repository is not even mapped to the job server and the job has been exported from the correct repository as command line execution of the job works perfectly fine.
Thnx
Just an update we were not able to figure out why this happened in the existing environment. One reason given was that somehow the commands which were being executed from BW side were getting corrupted. We had to build a new environment and this is no longer an issue in the new environment, as now all jobs can be executed from BW. Only difference between the 2 environments was we are now on 12.2.1.3 while earlier we were on 12.2.0.0.

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

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

)example of errors while loading data and how do u resolve them?

hai ram reddy this is ramprasad reddy....u can get this type of most commen errors....like below
As the frequent failures and errors , there is no fixed reason for the load to be fail , if you want it for the interview perspective I would answer it in this way.
a) Loads can be failed due to the invalid characters
b) Can be because of the deadlock in the system
c) Can be becuase of previuos load failure , if the load is dependant on other loads
d) Can be because of erreneous records
e) Can be because of RFC connections.....(sol: raise the ticket to BASIS team to provide the connection)
f)can be coz of missing master data.
g)can be coz of no data found in the source system.
h)Time stamp error........(sol: activate the data source and replicate the data source and load)
i)Short dump error.........(sol: delete the request and load once again)
j)Data locking when loading in parallel.
k)ODS activation failures.
l)No SID found........(sol: should load masterdata before transaction data)

Error while loading application

Hi,
I'm not sure this is the right forum, but I try anyway.
I'm trying to use a 3rd party Java application Unico (just use it, I don't develop anything of that) that after working for weeks, suddenly refuses to load at startup, and returns an error like "Error while loading application" (no error code number no other hint about the problem).
The tests that did not work: 1. I installed the Unico again, 2. I created a new login and installed Unico in that login, 3. I started in safe mode (pressing shift at startup) - I always had the same message and loading aborted.
The only workaround I found is to use an external startup disk, that I fortunately had available to face cases like this: when starting the system up from that disk Unico WORKS, not only, but I can even use the same application in my internal disk that does not load otherwise.
My first conclusion is that something wrong happened to my system on the startup disk that prevents loading a Java application. The user Library seems to make no difference.
So my questions to the Java experts are:
- what in the system could suddenly block the loading of a Java application ? where should I look in the system (I can use the terminal and know something about UNIX) to fix this ? could this be caused by a permission problem ? (it looks a lot alike, but repairing permissions in Disk Utility didn't help) if so where are the Java support files stored in the Library and System Library to check and compare between the good and the bad system ?
- is there a better workaround to this problem, other than starting up from a different disk ?
Some additional info:
- the application Unico is freely provided by the Italian tax organization, so there is basically no support to use it...
- Unico requires Java 1.3.1: my system is constantly updated/upgraded and it runs the most recent release that is 1.4.0 (I guess...) and anyway worked very well till a week ago.
- since the last time the application had worked I installed two (non Apple) packages: the TomTom (GPS navigator) setup application, and new Epson printer drivers for my new printer.
- in all cases I repaired permissions and I also verified the disk with the disk utility
- Unico does not uses printers (it creates pdf files instead) and does not use USB, which in turn is used by both the Epson driver and the TomTom app.
So I cannot connect the Unico malfunctioning to this new SW except for the fact that I cannot find any other answer...
Thanks to anybody having any suggestion about
Piero

I made some research: it seems to me that most (if not all) the Java machine is in the /System/Library/Framework/JavaVM.framework folder: but I found no evident difference in the file permissions between the good and the bad system (see my previous posts).
There are other locations where there are java related files: eg in Javaconfig.plist (in /System/Library/Java) that seems to name the locations for all components of the java machine. I checked some files in /usr/bin referenced in the .plist: again no difference.
Something "could" be a clue; just before the crashing point the Unico (java) program causes a message in the Console:
"[JavaAppLauncher Warning] Specifying a specific version for JVMVersion 1.3.1 is deprecated. Use the more general 1.3* instead."
This would be a clue... except that this message appears also when the program loads without problem (in the "good" system where it works). So it is more a warning.
Another clue is the message that appears in the console in the "good" system when the Unico loads correctly; and this seems really an error message (whateve it means):
"Index 1 for 'pxm#' 2062 out of range (must be between 0 and 0)
Attempted to read past end of 'pxm#'(2062) resource"
The funny thing is that when this message appears, Unico loads with no probem, while in the "bad" system it doesn't even get to this point.
So in my opinion both messages are irrilevant to identify the problem.
Or not ?
And again my main question is: what in the system could suddenly block the loading of a Java application ?
Thanks for any hint
Piero
