JCO Error JCO_ERROR_XML_PARSER

Hi All!
I am making a call to an adaptive RFC module on our SAP 4.7 System.
But i fail in executing the call.
this is the error:
Expecting a tag to begin with '<' instead of '0', in "00000000 ", error key: JCO_ERROR_XML_PARSER
I tried searching the forum for results, an saw that this error is because of an error in the metadata XML file.
But, this is Webdynpro, and as i am convinced, you are not to change anything in any XML files,
i tried making the call from to different projects, and the error is the same in both.
Anyone has any ideas ?
Help is much apreciated
Best Regards
Ronni Hostrup

Hello,
I think this is a bug in JCo & adaptive RFC here. I will asked for a redesign of the BAPI structure to get a flat structure and try that.
After searching documentation for any hints about this I can't see anything, but obviously its not working. I will open a new thread with the question, whether nested structures are allowed.

Install the 32bit version of the Java connector. BOBJ is 32bit so even on 64bit Windows you need the 32bit version of the Java Connector.

JCo error when calling from webmethods sap adapter to SAP BAPI

Hi,
I am getting an error "[SAP.102.9000] JCo error: (104) RFC_ERROR_SYSTEM_FAILURE - connection closed without message (CM_NO_DATA_RECEIVED)" when webmethods sap adapter is calling BAPI in SAP. The BAPI is working fine in SAP.

JCO Error in Quality Portal

Hi ,
When i am running WDJ apps in dev portal , it's working fine . But when i am running through QA , it's showing the following JCO error .
Could not create JCO connection .Please ensure that you have nesured RFC destinations and/or logical system name properly for this model .
I tested the JCO in QA and it's working fine . Can anybody help me out regarding this .
And one more question , how to check JCO connections for WDJ apps inside NWDS ?
Thanks a lot .

Hi Jain,
While using RFC Models in the WD application, we maintain JCo dstinations.
These are specifically used to create a JCo Connection between 1 Web Application Server and 1 R/3 System. If any one of them changes, you need to update the same in the JCo destinations created.
The point here is, as you have changed the Dev System to QA System, i.e. your Web Application Server, you will need to create / maintain the JCo Destination with the same name on the Quality System for use of the application.
The JCo connection that you have been testing, is, may be on your developemnt system.
Hope it helps.
Regards,
Alka.

Thanks

Thanks for your rapid answer
Very funny thing - after I made cold backup (stopping XI) it started to work(I saw my XML in SXMB_MONI), but when I did this the next time(adding fields to my RFC) the same happened...
Full cache refresh didn't solve the problem...
Any idea?
Thanks a lot

Using JCO error Wrong repository version = 0 encountered.

Hi Guru,
We convert our existing Java Jco program to call RFC Sender adapter and XI should forward the request to RFC receiver adapter to our ECC.
We found that when we create client connection using gwhost, gwserv and tpname which is config in RFC sender adapter.
In our Java program throw error in the step of mRepository.getFunctionTemplate.
The error is "Wrong repository version = 0 encountered.".
It seems the program can not access function template from repository.
Anyone have this experience before, please advise
Thanks you.

It's working now.
For your knowledge, it seems it was something wrong inside the jrfc.jar.
The problem is not exactly the same but the solution is to apply OSS note 816491.

Jco: Error Connecting using sapgw04

Hi,
I have a problem using Jco to connect to a SAP-System.
I'm trying to connect to SAP using the following configuartions:
     sysnr:           04
     GWServ:      sapgw00
     GWHost:      XXX.YYY.com
     ASHost:      XXX.YYY.com
The code to create a repository for this configuration is:
     JCO.addClientPool(poolname, maxpoolsize, "538", "username", "password", "DE",
               "XXX.YYY.com", "04", "XXX.YYY.com", "sapgw00");
When I use this pool to get a function I get an Exception:
com.sap.mw.jco.JCO$Exception: (123) JCO_ERROR_FUNCTION_NOT_FOUND: Server repository could not create function template '[FUNCTIONNAME]'
caused by: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect from SAP gateway to RFC server failed
Connect_PM
     GWHOST=XXX.YYY.com , GWSERV=sapgw00, ASHOST=XXX.YYY.com , SYSNR=04
LOCATION
     SAP-Gateway on host h33e / sapgw00
ERROR       partner not reached
     (host XXX.YYY.com , service <b>sapgw04</b>)
The strange thing is the sapgw04 in the error-message.
Somehow JCO wants to use sapgw04 to connect to the RFC-Server. Is this an error in the SAP-Configuration or do I have to change the configuration of Jco?
How can I tell Jco not to use sapgw04 but sapgw00?
Any help would be appreciated!
Thanks
Torsten

Hi Torsten,
please check how you log on to your system. You are giving a system number 04, which corresponds to sapgw04. I'm not sure why the method needs all the information, seems to be duplicate to me (please comment if I'm wrong); it should be sufficient to use:
addClientPool(String key,
   int max_connections,
   String client,
   String user,
   String passwd,
   String lang,
   String ashost,
   String sysnr)
If you don't want to use sapgw04, just specify "00" for the sysnr.
Hope this helps, harald

Jco error

Hi Friends,
Itu2019s a support issue. Messages have failed in integration engine and inbound queues
I am getting different errors in different areas of xiu2014
In Integration engine Problem while determining receivers using interface mapping u201CCommunication failureu201D during JCO CALL
Similarly another error in other message in Integration engine unable to find URL for adapter engine.
In SMQ2 error is XI Error JCO_SYSTEM_FAILURE.MAPPING: Queue stopped.
Pls help !!

As suggested by Prateek, please check whether the SM59 destination AI_RUNTIME_JCOSERVER is working or not. If this is not working, search for AI_RUNTIME_ZX2 in smgw=>Goto=>Logged on Clients.
If you find the program ID AI_RUNTIME_ZX2 in TP name column and still have issue, please ensure that the user-id id PI_JCO_USER is not locked or the password has not been changed.
If you can not find the AI_RUNTIME_ZX2 in TP Name column, that means there is an issue with JCo RFC provider. In Visual Admin(PI 7.0) / NWA (PI 7.1), do the necessary stuff which makes the program ids to appear in smgw logged on clients. Basis should know about this.
Hope this helps.

JCo Error in EP6.0

Hi All,
I have developed a custom iview in EP6.0 which retireves data from R/3 using Jco and display the data in various controls like dropdown.
When I try to run the application I am getting a runtime error (while accessing the model).
I am using a JSPDynPage with a java bean for pulling the data thru JCo.
When run as a standalone the the java class for JCo is working fine, and the bean is also working fine with static data.
Is there is anything that needs to be added in portalapp.xml file?.
Any help is greatly appericiated.
Thanks,
Vasu.

Vasu,
This is what I picked up in the EP6->Java Development->Documentation area.
"JCo in the Portal Platform
JCo is included in the portal platform. However SAP JCO/ JCOClientService should not be used anymore in Enterprise Portal 6.0 and above.
Webservices or the "Java Connectivity Architecture" implementation "SAP Connectorframework" is recommended instead. This Framework provides additional functionality, especially the connection management, which allow tp programm scalable connections "
You should probably follow the example code to connect to SAP using Java Connector functionality as suggested by SAP.
Hope this helps.
Thanks
GO.

JCO error when calling BAPI

Hello guys,
I have an scenario R3 -> XI -> R3.
From the first R/3 we call a function in a program to execute a BAPI in the second R/3, so the BAPI doesn't exist in the R/3 that starts the interface.
We have configured the TCP/IP connection and with the same program ID in the Sender RFC adapter. All the connectios are running successfully but when we execute the program we have the error:
JCO.Server could not find server function 'Z_TEST'
Do you know if the BAPI has to be created in both systems, or it's only necessary in the R/3 destination to run.
All connections are running so the question is what we remarked before, the BAPI must be created in both R/3 systems?
Regards,
Xavier.

Hi Xavier,
strange, i answered to a very similar question a hour before, there was no reaction by Gerardo Mondragon .
How can the sender adapter get the metadata? If the FM is just in the receiver system? Maintain the meta data connection at Communication Channel to the receiver system...
Regards,
Udo

The JCo connections SAP_R3_HumanResources and SAP_R3_HumanResources_Metadata are tested successfully and I see the gree light for these 2 in the WebDynpro console.
Can you please advice me here.
Thanks,
Vivek.

Vivek,
open the services file of your portal server box. This file will be in the location C:\WINDOWS or WINNT\system32\drivers\etc folder. In that enter an entry as below:
sapmsED0 36XX/tcp
where XX is the system no of your R/3 system. So if R/3 system number is 30 the line would be sapmsED0 3630/tcp.
Save the file and then try accessing iView again. This error message would be going off.
Regards,
Shubhadip

Hi Phani,
Check the followin
1. in your Back end system, go to SMLG -> check logon grp PUBLIC is there or not.. if nt create one
2. Check out that, from EP server you can ping ECC system and its gateway services, message server services.
3. In your case, u shud be able to ping ptgsap10 from EP server and shud be able to access sapmsEC6 service.
4. If u cant ping host, maintain host file entry with IP address and host name
If u can cant access sapmsEC6 , then maintain services file
sapmsEC6 <message server port>/tcp
Cheers!!
