Error in SAP_R3_SelfServiceGenerics_MetaData JCo.

Hi All,
While checking the ESS home page i get the following error.
com.sap.dictionary.runtime.DdException: 'SAP_R3_SelfServiceGenerics_MetaData' not properly defined! Unable to create Metadata connection for Dictionary Provider. Either the logical System Name 'SAP_R3_SelfServiceGenerics_MetaData' has not been properly defined in the System Landscape Directory, or you are not using a MsgServerDestination (AppServerDestinations are not permitted for Metadata connections)
However if I check this JCo from Content Administration>WebDynpro>Maintain JCO destinations the JCO is properly configured.
The ping and test are successfull for this JCO.
Kindly help.
Regards,
Rohit

Hi Rohit,
You need to make sure that the RFC you're trying to run from this connection is exists in the backend that the RFC destination points to.
This can happen if you have:
Backend A, Connection A, RFC A
Backend B, Connection B, RFC B
If you'll try to run RFC A from connection B you'll get DD exception because the metadata can't find to RFC A in Backend B.

Omri

Error while obtaining JCO connection when creating JCO connection

Hey,
im having a problem when creating a JCO connection in the Web Dynpro Content Administrator. Creating the Modeldata (Application Data Data type) JCO Worked but when creating the JCO for the RFC Metadata (Dictionary Meta data) there is a problem:
In step 3.2 Msg server connection I cannot specify a system name and logon group, only the message server can be selected with the dropdown box.
After pushing the finish button i get the following stacktrace:

Hi
Please configure your SLD. Your SLD holds the system definition. Define a SAP WebAS abap system and then try to create a Metadata connection using WebDynpro content administrator. Now you will be able to see the msg server defined in the dropdown. Also ensure that you have the message server entry in your services file.
Refer these links for SLD

Thanking.
Rajendra

Hello Rajendra,
Good to hear from u. Let me try to give a soln for this problem of yours.
I think probably the logon group has not been specified in the backend.If thats the case then do the following:
Connect to the backend server for which you are trying to create the JCO. Run the transaction SMLG. It will show u the existing logon groups. carry out the following steps if the 'PUBLIC' group is not present in the list of logon groups.
Click on the create button. In the pop-up, type the logon as 'PUBLIC'. For the instance, select the F4 help and choose the existing instance number. Click on copy and click save. Try running the transaction /nsmlg and now it should show the logon group 'PUBLIC'.
When you create the JCO connection, it should now show the logon group 'PUBLIC'.
Regards,
Prathamesh.

Error while obtaing JCO connection

In Bussiness planning in portal. When i click Planning tab in Enterprise portal, its throwing an error that "error while obtaining JCO connection". I cant proceed furtherI

please give some pointers like what needs to be done JCO settings in Backend.
Thanks in advance.

Niranjan,
3 causes and many more....
First and most probable cause is that your CR content in SLD is old....
FIX - to fix this download latest cimsap and crcontent from service.sap.com and implement in SLD.
Second cause user is locked
FIX - unlock in R/3
Third cause could be that the connection pool in JCO is exhausted.
FIX - increase connection pool in JCO.
More causes.
With this new version it appears that any error before connection is created ends up showing this, so I would really go into default trace and look there for original errors, that is the way I found JCO pool was exhausted, that error was not being forwarded and instead it was showing this error...
reward points if helpful

Error connecting using JCO.Client: null

Hi,
I created a WD app which uses the RFC FM. I followed How-To-build-webdynpro.pdf document to create the WD and trying to deploy and run, I see the view page but when I trigger the action via button UI element I get following error as exception in the try catch block of execute method
In the NWA I see
Could not create JCOClientConnection for logical System: 'WD_MODELDATA_DEST' - Model
An exception has occurred: Erorr accessing cache [region]='XCM_SESSION_SCOPE'.
[EXCEPTION]
com.sap.isa.core.cache.Cache$Exception: Cannot return access for region 'XCM_SESSION_SCOPE'. Cache is not ready
I'm using following existing JCO definition by configuring them with correct parameters. Tested them successfully
WD_RFC_METADATA_DEST
WD_MODELDATA_DEST
What am I missing? In SM04 tcode I see 2 connections are opened with 2 Megabyte not released for a long time. I think if connections are released correctly it should drop to 1 megabyte. Is there anything that I need to do just after execute method as shown below (I have replaced function module with <FM> in below code)
try {
 wdContext.node<FM>_Input().current<FM>_Get_InputElement().modelObject().execute();
 } catch(Exception exception) {
 msgMgr.reportException(exception.getLocalizedMessage(), false);
 wdContext.nodeOutput().invalidate();
 msgMgr.reportSuccess("Success");
The error is in the catch block which is displayed on the view page.
Thanks
Praveen
I modified the above code and put in finally block to close the connections as follows, please let me know if this is OK. I still get error message as "Error connecting using JCO.Client: null" but no additional connections in the SM04 after adding finally block.
try {
 wdContext.node<FM>_Input().current<FM>_Get_InputElement().modelObject().execute();
 } catch(Exception exception) {
 msgMgr.reportException(exception.getLocalizedMessage(), false);
 }finally {
 // disconnect the connection
 wdContext.<FM>_Get_InputElement().modelObject().modelInstance().disconnectIfAlive();
Edited by: Praveen11 on Oct 5, 2009 9:06 AM

Thanks Satish.
The issue is resolved. I think it was to do with permission, as I was running directly from NWDS deploy and run the session didn't have proper authorisation or something that was causing this error.
When I copy pasted the URL in the correct browser session window I got no error and function module was successfully executed. However the issue now is that values are not showing up in the view may be to do with mapping context or model I'll review and post back as different thread.
Thanks
Praveen

Error connection using JCO.Client

Hello all,
I got the following problem "Error connection using JCO.Client" and don't know what's wrong. All connections works at the content administration when I test the connection.
Can anyone help me please?
Best regards
Petra

Hi,
I almost tested the JCO connection with the 'test' button successfully at the content administrator. I tested again and it still works. And I have a stand alone webdynpro application (no portal).
Now I got the following error message after completing the coding with 'e.printStackTrace().'.

"Error connection using JCO.Client:null"
"[Ljava.lang.StackTraceElement:@60db08"

Can anyone explaine me what's wrong?

Error connection using JCO.Client :null

Hi,
I have small doubt in JCO connection, can any one help me.
In WebDynpro application some time we are getting exception like Error connection using JCO.client : null.
Connection :200 we are maintained in JCO configuration.
If I call one RFC useing JCO it will created a session or connection to ECC server, because we are getting exception in server too many sessions to ECC server.
Write now we are not using any code to close the connection like.
SaveModel svModel = (SaveModel)WDModelFactory.getModelInstance(SaveModel.class);
svModel.disconnectIfAlive();
If we use the above code it will close the connection or sessions.
Is it recommended to write the code in every RFC calls or in final block of all RFC calls ?
Regards,
Satya.

WDDynamicRFCExecuteException: Error connecting using JCO.Client: null

Hi
This is a common problem,I have seen many threads , but following them did not solve my problem.
I have the JCOs tested successful from WD Admin. When I create a sample WDJ application with RFC model and deploy it to the server, I get
Exception:com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecution: Error connecting using JCO.Client: null.
I have checked my binding , I have only one input parameter and the code is
      wdComponentAPI.getMessageManager().reportSuccess("Inside wdInit in Component ctrller");
      Z_Plm44_Obsoleteimpactanalysis_Input input = new Z_Plm44_Obsoleteimpactanalysis_Input();
     wdContext.nodeZ_Plm_Input().bind(input);
     wdContext.createZ_Plm_InputElement(input).setV_Type(wdContext.currentZ_Plm_InputElement().getV_Type());
Also I have implemented closing the connection
disconnectifalive
I contacted the basis team... they tell me that everything is fine from their end. they have tried increasing the JCO connection pools.
Thanks for your help in advance
Karthika

Hi Karthika
Check this pdf and try to catch WDDynamicRFCExecution in catch block.
Please put your code in try catch and also import com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecution in your code;

Error connecting using JCO.Client: null in xRPM in EP

Hi Friends,
I am getting the following error in xRPM through EP
"Error connecting using JCO.Client: null"
I can't enter xRPM, but I can enter other Business packages iViews.
The problem is intermittant and user specific.
Can you pls provide any input on this ?
thanks in advance and warm regards
Purnendu

Hi Flavio,
Thanks for your reply.
The user is created both in the backend as well as in portal.
The roles are also ok.
The error I am getting only while accessing xRPM iViews.
If I restart the instance the error is removed. But it reappears again may be after few days.
This error is intermittant.
May be it is related to the Maximum Number of JCo connections in the WebDynpro configuration.
But I don't have much idea on that.
Can you pls provide any help on this.
Warm regards
Purnendu

Error in launching guided procedure: Error while obtaining JCO connection.

Hello experts,
we've a problem with webdynpro java calling a guided procedure.
We've defined an endpoint for our callable object, as you can see the test of the connection works fine:
In the configuration of our callable object we use the endpoint above:
And we can test the callable object: it works well, call the right BAPI and find the results.
But when the GP is called and this callable object try to call the BAPI in the background it doesn't work at all.
In the log and trace of the portal we find this:
A technical callable object exception ocurred: Le service RecupActeurs n'a pas pu être exécuté : La connexion pour le nom de connexion SAP_R3_HumanResources n'a pas pu être chargée à partir de System Landscape Directory (SLD) : Error while obtaining JCO connection.

It seems that the GP could not connect to the SLD to call the JCO, but as said before, when we test the callable object, it calls the BAPI without any problem.
We tried to recreat either the JCO and the Endpoint but without success.
Any help will be appreciated.
Thank you.

Hi.
Thanks for your answers.
Here are the things :
From the GP administration, the endpoint's test is working.
From the SLD, the JCO is working too.
From the Web Dynpro Content Administrator, the JCO's test is working too.
From the GP Desing Time, the callable object supposed to call the FM uses the right endpoint, and the test is working too, we retreive data from the backend.
From our app, calling the GP process that includes our callable object, we have errors pasted above...
Regards.
