JCo...
Hi.
I have heard that it is possible to call Java code from
ABAP using JCo. It seems authorization is required to
download the JCo from http://service.sap.com/connectors.
Does any one know an alternate link?
Also, pls do give me some sample code on how a Java
method "testMethod" in class "com.test.pkg.TestClass" is called from ABAP.
Thanks in advance.
Hi Tanveer/Anandaraj,
Could you kindly email me this document where I want to call Java methods from ABAP using RFC/JCO.
Any other inputs from your learning is also welcome. My email id is [email protected]
Thanks for all your help.
Best regards,
Divya Rao

Error while selecting Load Balancing in JCO creation
While creating JCO i am facing this error.It is working fine with Single server connection,but when i chose Load balancing i error comes out.Please tell me the solution.
I have read couples of forum mentioned you need to start both Portal and ECC.
For you information my Portal and Java are both on diffrrent Box.
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=olameccpdvr GROUP=PUBLIC R3NAME=DVR MSSERV=sapmsDVR PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service 'sapmsDVR' unknown TIME Thu Feb 24 12:19:54 201 RELEASE 701 COMPONENT NI (network interface) VERSION 38 RC -3 MODULE nixxhsl.cpp LINE 776 DETAIL NiHsLGetServNo: service name cached as unknown COUNTER 5Is your backend system configured correctly in your SLD ?
Go to transaction SMMS on your backend system that your are connecting to. Click on Goto=>Parameters=>Display. Look for "server port" value.
This should give you the TCP/IP port for your message server. It could be 3600 or 3601 (36NN - where NN is the instance number).
In your services file, if you made the entry at the end of the file, press Enter (Return) after your entry.
Try restarting your server after making the above changes.

Error in creation of JCO with Load balancing server
Hi,
We are using a ABAP user base for our WEBAS server 6.40 (with ABAP+JAVA). i have created a Public group in concerned ECC 5.0 system. I have already configured SLD, and then i maintain data supplier bridge in SLD and run RZ70 in ECC 5.0 system to load system information.. i can see details in SLD ..
now i am trying to create JCO connections .. here i am unable to create JCO with load balancing option.. i get
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=<servername> GROUP=PUBLIC R3NAME=SID MSSERV=sapms<SID> PCS=1 ERROR service 'sapms<SID>' unknown TIME Fri Jun 16 12:41:20 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapms<SID>' not found SYSTEM CALL getservbyname_r COUNTER 1
i am able to create single server JCO, but it fails in load balancing.. is there anything i have missed out in settings...
Thanks and regards,
SudhirThanks, Bogdan Rokosa
I have the same problem,and solved it following the steps provided by Bogdan Rokosa :
you must insert an entry for your R3 system
(like: sapms<SID> 3600/tcp)
in services file
(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.
I test the Jco successful without restart J2EE Engine. -
Hi All,
After two years of CTS+ working without issue, in the last fortnight JCO_ERROR_LOGON_FAILURE has occurred. I have reviewed all the configuration in document http://scn.sap.com/doc/DOC-30177, and it all looks fine. The user configured also checks out fine as well. The user id that is causing all the trouble is CTS_<SID>. We chose this option so we could determine which user in case of future issues. We have two development paths, Project and BAU. So at anyone time transports that have started in the BAU development system will need to be imported into the Project development system (using transport express) and vice versa. Attached is the security authentication log from the system showing authentication failure. I have also checked the transport routes defined for the business systems in the SLD and these look fine as well. Roles assigned to the user are SAP_CTS_PLUS,
SAP_J2EE_ADMIN, SAP_XI_CMS_SERV_USER, SAP_XI_CONFIGURATOR, SAP_XI_DEVELOPER, Z_CTS_PLUS_ADDITIONAL. I have also checked the permissions on the file at the operating system level.
Any suggestions/advice gratefully received as this really has me scratching my head.

I have these parameters on my Connection Pool and sometimes appear these wrongs in my application:

Are there something wrong with my connection pool?
What can be happening?

JCO connection pool is exhausted
hi
I am using RFC module in my web dynpro application. When the application is used for sometime, the JCO connection will get exhusted. The JCO connection will not release itself. I can't find any method in web dynpro to release the connection manually. How can I solve this problem?Hi,
What is scope of the connection. View properties of MODELDATA and METADATA destinations.
You can change the scope of the connection..
or
wdContext.current<BAPI INPUT>Element().modelObject().modelInstance().disconnectIfAlive();
For more ways , give a forum search.. There are a lot of close forum posts.. Gud luc..

Problem with JCo Connection Pool
Hi,
I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:
com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.
So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.Hello,
You need to increase the pool size via Visual Administrator.
Server 0 -> Services -> JCO RFC Connections.
Change the pool size from there. I believe a restart is in order.

Hi All,
Can anyone help me to connect to SAP from JCO using logon group....appericate if you can give some example such as sample code on how to connect using logon group. Its is urgent.
thanks!
prabHi Pardeep,
Thanks a lot!!!
It seems now the connection is working. I passed the parameters u have told and now I am not getting any connection error.When I print
System.out.println(myClient.getAttributes());
It returns me the following with correct IP address:
OWN_HOST: bpcbz6n
PARTNER_HOST: 172.30.xxx.xxx
SYSTNR: 02
SYSID: TS1
CLIENT: 203

OWN_CHARSET: ISO8859_1
OWN_ENCODING: ISO-8859-1

PARTNER_CODEPAGE: 1100
PARTNER_CHARSET: ISO8859_1

PARTNER_REL: 620
PARTNER_TYPE: 3
KERNEL_REL: 640
TRACE:
RFC_ROLE: C
OWN_TYPE: E
CPIC_CONVID: 385948
So this means connection is working?
But when I call the RFC, it is returning me null value. When I call the following RFC, the functionTemplate instance is returning the "null" value. What can be the cause of it?This RFC exists in the SAP. I hope connection is working?
IFunctionTemplate functionTemplate = aRepository.getFunctionTemplate("Z_RFC_PLANTS");
thanks! -
Adaptive RFC 2 gives error: com/sap/ide/jco/service/internal/R3Service
Hi,
I've run into the following problem about NWDS. This happens as I create a Model. It appears there is a new version of the Adaptive RFC Model, which is called Adaptive RFC 2 Model.
1. Right click on Models, and select Create.
2. Double Click on Adaptive RFC 2 Model
3. The error pops up. It says "An error has occurred. See error log for more details. java.lang.NoClassDefFoundError". Then if you click details you get "An error has occurred. See error log for more details. com/sap/ide/jco/service/internal/R3Service "
If you know which log to have a look, or what this error is about please let me know urgently. Any help if much appreciated.
Thanks,

SubhankarHi Manoj,
I have added the libsapjcorfc.so and librfccm.so files to below locations:
WL_HOME/server/lib
MW_HOME/Oracle_SOA1/soa/thirdparty/ApplicationAdapters/lib
MW_HOME/user_projects/domains/base_domain/lib
And also set the LD_LIBRARY_PATH and WEBLOGIC_CLASSPATH in commEnv.sh file.
Eg:
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${WL_HOME}/server/native/linux/${arch}:${MW_HOME}/Oracle_SOA1/soa/thirdparty/ApplicationAdapters/lib:${MW_HOME}/user_projects/domains/base_domain/lib:${WL_HOME}/server/native/linux/${arch}/oci920_8
Is there any other location where these need to be added ? I hope library path/system path refers to the WEBLOGIC_CLASSPATH ?

Where to get the SSO ticket for a JCO-Connection from?
Hey All,
The szenario is, I've got a Java application and I want to connect to a SAP System. For this I want to use SSO. In the documentation of JCO I found this phrase:
For SSO specify the user to be $MYSAPSSO2$ and pass the base64 encoded ticket as as the passwd parameter.
Well... Now my question... Where to get this base64 ticket from? The problem is, I'm NOT using WebDynpro, it's a custom application running on client side. Now how to get the needed information? (PSE?)
It would be great when you could give me a clue.
Best regards,
KristianThis linksactualy leads to the same place I mentioned where
it installs the
player over the Internet
Another thing is that these players are said to be different
for different
browsers which means they are working together with a
browser. I am looking
for a player which allows to play SWF file directly, without
a browser.
I have such a player installed together with FLASH-8 - I am
looking for
such a player

R/3 Accessibility via JCo Destination
Hello
We have a WebDynpro application running in an SAP EP 7.0 SP15.
We have metadata and modeldata JCo destinations defined for an R/3 backend system.
The WebDynpro application is using the modeldata JCo destination to reach a BAPI in the R/3 backend system.
As far as SSO access is configured for the modeldata JCo destination, it is required that the Portal user of the WebDynpro applications has an user defined in the R/3 system.
We would need to find some solution so that the WebDynpro application can access the BAPI in spite the runtime Portal user does not exist in R/3 backend system (e.g. accessing R/3 system with another user, that could be hardcoded or mapped to the Portal user or whatever).
Is that possible? If yes, how?
Thanks a lot!
Regards,
JonI think that perhaps you posted this question in the wrong Web Dynpro forum. This question appears to be Web Dynpro Java related and not Web Dynpro ABAP. Please confirm otherwise I will be moving this thread to the WDJ forum where it seems to belong.

I have configured my SLD as well. Any suggestions. Please Advise.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,
Divya

JCo 3.0 connectivity issues between Java application on NWCE and ERP
Requirement: We have a Java application that would run on NWCE. This application will be invoked from ERP/SAPGUI via HTML Controller. With SSO enabled, the goal is to pass ERP credentials to CE application. This CE application in turn will use ERP credentials from Logon ticket to connect to ERP and invoke BAPI calls (JCo 3.0 destination)
System Information:
CE System: SAP NW CE 7.2 SPS 04
ERP: SAP ECC 6.04
Both systems are trusted using X.509 certificates
Current scnerio:
1) Destination (CE to ERP) - JCo 3.0 using Authetication method of u201CCurrent User (Logon Ticket)u201D
- Web application is unable to find the JCo 3.0 destination.
2) Destination (CE to ERP) - JCo 3.0 using Authetication method of u201CTechnical Useru201D
- Web application is able to find the JCo destination
Any assiatance in resolving the issues would be appreciated ....

Hi all,
I m using look up through JCO and calling a RFC on backend R/3 for the particular validation.I m using UDF for that.In the UDF i have specified imports as:-
imports :-java.util.;java.lang.obj.;com.sap.aii.mapping.lookup.;com.sap.mw.jco.;java.io.*;
source code --
//write your code here
JCO.Repository myRepository;
// Change the logon information to your own system/user
JCO.Client myConnection = JCO.createClient(
// all the client information namely client ,user id pwd etc
myConnection.connect();
// create repository
myRepository = new JCO.Repository( "SAPLookup", myConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("xxxxx"); //Name of RFC
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( a , "xxxxx" ); //import parameter of RFC, a is input argument.
myConnection.execute( function );
String ret = function.getExportParameterList().getString( "XXXX" ); //export param
myConnection.disconnect();
return ret;
however on test i m getting follwing error:
Source code has syntax error: D:/usr/sap/XID/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Map6df266d0f96411dbb2a4000bcd3f5f3d/source/com/sap/xi/tf/_MM_Source_To_Target_.java:157: 'class' or 'interface' expected public static void main(String[] args) throws Exception{/!_$ClNRep_/_MM_Source_To_Target_ st = new /!_$ClNRep_/_MM_Source_To_Target_(); st.testExecute(); }
Can anybody help me out in rectifying this Syntax errror.
Regards,
AshwinMYou are hardcoding the user id , password etc in your UDF. This is something will cause issues asyou move your objects across environments from Dev to Qaulity and production.
You cannot change the user id and passwordi n your mapping code in your Quality and Prodction. Use of RFC Lookup is strongly recommended with the RFC adapter.
I dont think using RFC Lookup API causes any perfromance degradations. We have used this feature multiple times in and have never faced performance constraints as a result of this.
