Error In JCO Destination Creation

Hi,
I'm creating JCO Destination in Web Dynpro for Java. While finishing the JCO Destination wizard it shows a error as follows:
Root Cause
The initial exception that caused the request to fail, was:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
    at java.util.ArrayList.RangeCheck(ArrayList.java:507)
    at java.util.ArrayList.get(ArrayList.java:324)

    at com.sap.tc.webdynpro.progmodel.context.Node.setLeadSelection(Node.java:749)
    ... 45 more
But the JCO Destination is created successfully and I can test and ping tit successfully. But it becomes the part of System Denied JCO Destinations.
In the server log file I'm getting the following log:
1.5#00112F5374F1005B0000011100000EDC000443BF97417983#1200390062389#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#sap.com/tcwddispwda#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#Guest#0#####SAPEngine_Application_Thread[impl:3]_14##0#0#Error#1#/System/Server/WebRequests#Plain###Processing HTTP request to servlet [dispatcher] finished with error.

Can anybody help to find out this problem.

Hi,
This is a Web Dynpro bug. You need to apply the latest patch for Web Dynpro runtime.

Error in JCo Connection creation

Hi All,
When I create a JCo connection on my local J2EE it fails with the error enclosed as below:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=frces4066 GROUP=PUBLIC R3NAME=AM1 MSSERV=sapmsAM1 PCS=1 ERROR partner not reached (host frces4066, service sapmsAM1) TIME Mon Apr 03 18:44:33 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 MODULE nixxi_r.cpp LINE 8596 DETAIL NiPConnect2 SYSTEM CALL SiPeekPendConn ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 1
When I try and ping the JCo the error is as enclosed below:
Failed to ping JCo destination WD_COMMITMENT_MODELDATA_DEST
I have maintained the enteries in hosts file as well as the services file and when I telnet the server on port 36XX where XX is the system number of the system I create the JCo for it connects successfully.
When I test the CIM test for the SLD that connects successfully.
Where and why is the JCo failing after creation?
Can someone throw some light on this error.
Thanks in advance for all your help.
Best regards,
Divya

Hi All,
Anyone can help? I got the same problem. It seems that the PUBLIC group in NSP ABAP system can't not be accessed.
Here is my system landscape:
- I have installed the Java and ABAP in the same host
- My ABAP system is NW2004sSneakPreviewABAP, Java is SAPNetWeaver04_SP16Preview
1) I set up SLD successfully (import CIM, run RZ70, the ABAP system shown up in the Technical Landscape in SLD
2) I created JCO destination with Load Balancing but it failed to ping and to test
3) I already define the group 'PUBLIC' in tx SMLG but from SAPGUI I can't add the group. I got the error message "Message Sever could not find any group".
4) The PUBLIC group does not show if I run the program 'lgtst'.
Test lgtst:

500 internal error at Jco destination

When tring to create any Jco destination, we get "500 internal error".
Anybody has the experience to fix it? Thanks! Points!

Hi, Jennifer.
i'm sorry but "500 internal error" has too many possible causes.
You need more detailed info in the log files under the following folder.
/usr/sap/<SID>/JC00/j2ee/cluster/server0/log
So, please reproduce your problem and check the files - usually
defaultTraceX.trc and applicationX.log
Good Luck.

Hi Bhavik,
          As per ur instruction,In Webdynpro content administrator,Check SLD connection->Test connection if i test,it displays
Connection to System Landscape Directory was successfully tested.
In visual amin->CIM CLIENT GENERATION SETTINGS->CIM CLIENT TEST,it displays
CIMOMClient Object generation and connection test successful.
in webdynpro content administrator->deployed content,i am able to open all other webdyn pro application apart from the webdynpro application by using adaptive RFC model.
if i open the webdynpro application by using adaptive RFC model,then only i am facing this error.
pls let me know how to solve the error?

JCo destination error while executing the webservice model

Hi,
I have explained what I have done so far and whats my issue right now.
My requirement is calling a PI interface (exposed as webservice) from webdynpro for java and setting some parameter value to the PI interface based on which our functional flow will continue.
Done so Far :
1. Created a webdynpro for java application using NWDI.
2. received the WSDL file of the PI interface and imported as "Adaptive webservice model" into webdynpro.
3. used the model and set the parameters to PI interface and executed the model.
4. I have created JCO destinations in the source system (where the application runs) to communicate to the PI system. A special user has been created and assigned in the connection for communicating.
5. Also I have created the "Dynamic Webseviceproxies" in visual admin with the same name as the JCO destinations. It had a property "URL" for which I have tested with providing both the PI server URL (Http://<Hostname>:<Port no>) and also the complete webservice URL (Which calls the WSDL file directly)
when I run the application, I get the following error.
1. Exception on creation of service metadata for WS metadata destination 'WD_RFC_METADATA_DEST' and WS interface '{<Interface Name>'. One possible reason is that the metadata destination 'WD_RFC_METADATA_DEST' has not been properly configured; check configuration.
after some exception the next error follows
2. Invalid Response Code 403 while accessing URL: <The URL which I have provided in the webservice proxy in Visual admin tool> Response Message: Forbidden.
after some lines of exception from PI server the next error follows.
3. Error: You are not authorized to view the requested resource
My Question :
1. Do I miss anything in Configuration?
2. Is my way of approach wrong?
3. Any additional authorization needed?
Kindly provide some ideas and inputs.
Regards,
Mahendran B.

Dear Mahendran
JCO destination will not used for the Web Service Model. While creating the webservice model, you need to use the logical destination which you have created in the Visual Admin.
Please refer to the Secured WebServices II and verify currently used webservice logical destination How To Reimport Web Service Models in Web Dynpro for Java
You can also refer to

Hi,
Have you configured your SLD? Check JCO Destination error out or search for "com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.checkStatus" in the SDN forums.

Can someone say me, why occurs this error ? I have reviewed all my configuration, but I haven´t found nothing.
Thank you very much.

I think while creating the JCOs you must hav left some field with a NULL value.Try to check out that all the connection properties hav been specified correctly also make sure that the connection pooling has a small range.

RFC error while creating JCo Destinations

Hi Team,
We have been getting RFC_Communication_Error over time and again while creating MetaData type JCo Destination in EP 7. Actually We am configuring a Business package for ESS.
I am pasting the error,

We have created Application type connections successfully. the tests on these were also successful.
Thank you,

Creation of JCO Destinations for web dynpro

Hi all,
I read quite a lot of post concerning the subject but unfortunately I did not found a solution to my problem.
My goal is to create JCO Destinations to make my web dynpro to connect to an R3 system.
In order to realise this I followed these steps :
- Launch visual admin and set http settings, rfc settings, and cim client settings. I click on CIM client test and the result is a success so I assume this part is correct.
- In R3, I execute transaction smgw, go to remote gateway to get the gateway settings. I execute RZ70 and filled the parameters just checked. Then I activate and launch the data collect. I have no error message and everythings seemed to work fine.
- In the sld (<host>:<port>/sld) I configured my server settings, the I go to data bridge, set update local sld to true and fill RFC gateway info with the same values as in my R3 system. Then I restarted the sld.
- Finally I went to Web Dynpro content administrator to create my destinations and there I failed. After entering all settings (the message server appears in my technical landscape in SLD), when I click on finish I've got the following exception :

I tried to create a generic destination (no for the web dynpro tutorial) and failed again.
I do not undestand what I did wrong.
Does someone have an idea ?
Thanks for reading this !

This thread helped me too because before reading it I didn't thought that I had to create a logon group "PUBLIC".
Anyway I succed in creating 'WD_FLIGHTLIST_MODELDATA_DEST' and the test is ok. The problem was that in sld / technical system / web as abap, my Central Application Server host was wrong. It is not possible to change it so I just add a secondary server with the right host and select this one when creating the destination.
The only pb remaining is now 'WD_FLIGHTLIST_RFC_METADATA_DEST'. I think the pb is my message server such this is the only difference between the two destinations
Thanks for your help

RFC Adaptive Model,JCO destinations error

HI,
I created the tutorial application to get Flight List using RFC adaptive model.
I created the JCO destinations in web dynpro content administrator after configuring the SLD (after many problems though ).
Our Server is Web AS 6.4 ABAP + JAVA ,but no R/3 modules installed.
WD_FLIGHTLIST_MODELDATA_DEST-type application--single server connection
WD_FLIGHTLIST_RFC_METADATA_DEST-type Dictionary-load balanced
The JCo destinations status shows green.
The test for WD_FLIGHTLIST_MODELDATA_DEST is succesful but the test for WD_FLIGHTLIST_RFC_METADATA_DEST fails with the error:[code]
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=nwserver GROUP=PUBLIC R3NAME=NWS MSSERV=sapmsNWS PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR Group PUBLIC not found TIME Thu Nov 10 18:24:23 2005 RELEASE 640 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 3515 DETAIL LgIGroup COUNTER 2 [/code]
The ping fails and if i test it again,i get another error
[code]com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=nwserver GROUP=PUBLIC R3NAME=NWS MSSERV=sapmsNWS PCS=1 ERROR Group PUBLIC not found TIME Thu Nov 10 18:29:13 2005 RELEASE 640 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 3515 DETAIL LgIGroup COUNTER 1 [/code]
What is wrong?Any more steps required?
If i try to edit it,the type is still the same-Application with single connection.
How can i change it?Do i need to change it to type Dictionary in the first place? How to proceed.
Please guide.
Regards,
Siddhartha

ESS/ MSS JCO destination error...

Hi All,
I have created all JCO destinations and when i test them , the result is successful
But once i click on ess/mss tab in portals, i get the error..
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'SAP_R3_HumanResources_MetaData' in the SLD. No such JCO destination is defined in the SLD.
But i have maintained SAP_R3_HumanResources_MetaData in the SLD.. Actually i have two SAP_R3_HumanResources_MetaData services one is active and another is inactive..
For SAP_R3_HumanResources -- i have used "Logon Ticket" and for SAP_R3_HumanResources_MetaData -- used userid & pwd.
Actually i have to do UserMapping as my portal userid and R/3 userid are different.. Then in this case am i creating JCO destinations correctly.. If not how to do..
Please throw some light into this problem by your valuable suggestions.
Thanks & Regards,
Mahesh.M.R

Hi
I am having the exact same problem (i think). I believe that the problem is caused by a failed connection to the SLD.
In my case, if I scroll the bottom of the error page, the 'Detailed exception chain' has the error:
TypeBroker failed to access SLD: Error while obtaining JCO connection.
The same error can be found in the DefaultTrace.
This ESS is on a nw2004s sandbox portal (trying to reach an ECC 6.0 sandbox), but being lazy I just reused the SLD in my Development environment.
This is however a Java WAS 6.40 and according to Note 954820 (Compatibility of SLD in the system landscape)
QUOTE
In general, the connection of systems to the SLD is released for SLD client applications with releases earlier than or equal to the SLD release (to be more precise: the AS Java release on which the SLD runs). Within a release, all Support Packages are released.
UNQUOTE
So, i'll try activating the SLD on a nw2004s JAVA WAS and use that instead.

Stig
