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,
Kristian

How to Remove JCO Connection Config?

I have a NW2004s system that will not start. The Message Server and IGS Watchdog are running, but the Dispatcher is in a yellow state.
The last thing that was done on the server before it was restarted was 2 JCO connections were added. Now the system will not start and I do not know how to remove the JCO connections.
I cannot find relevant configuration within the Config Tool or the Offline Configuration Editor. I am unable to access the Visual Administrator.
Any ideas?
Thanks.
Paul

Hi,
If you created JCO connection, then you can remove as follows
1>go to Portal URL(Ex:http://102.26.88.65:50100/irj/portal)
2>Go to content administration ->webdynpro-> Maintain JCo connections ->Remove what ever your JCo conn created.
or search for the JCO connections you created in search box left -->delete

JCo Connection Performance Tuninng

Hi all,
Here's a performance tuning problem occurs when I do the Stress Test for a JCo Connection.
I call bapi with abap model autogenerated by webdynpro wizard, then I developped a method to do this post job(with same data, suppose each post get the right response) for 1, 10, 20, 50 times.
I found the first time it will cost a real long time(such as 21s) to get return, then performance can be better, an average time cost is about 700 ms.
So I think there must be someplace to cache the post data, if I can modify the size of the cache, maybe I can improve the performance.
Now the question is where is it?
Any idea?

Need help in JCO connection creation/maintanence.

Hi,
In our project we have EP system ( Java Stack).We need to form the JCO connection that is required to deploy the web dynpro applications.We have taken a couple of JCO connection which are already there SAP_R3_HumanResources & SAP_R3_HumanResources_Metadata.For SAP_R3_HumanResources_Metadata JCO connection the user existing is a dialog user,also not having sufficient authorization to access all DDIC functions.My question is that what authorization required to user in this case to access all DDIC functions?Also for SAP_R3_HumanResources JCO connection what all prerequisites we require?.In this environment CD2 ( Dev.SAP system) is acting as backend to production portal PP6 system.Please let me know if you want any more details from my side.

Hi nileshshete
I quote this from sap-img.com:
There are many functions of DDIC user.
For E.g.. When you configure TMS you won't be able to configure it using sap*. For this you need a user who has access to Data dictionary and ABAP repository Object like DDIC user or user with sap_all and sap_new permission.
http://www.sap-img.com/basis/function-and-role-of-user-types.htm
I think u need a user with sap_all premission.
Hope it helps,
Nitsan

How to use a JCO connection pool in an EJB?

Hi *,
I want to build a WebService using SAP Web AS (J2EE Engine) that connects to a R/3 ERP (release 4.7).
I thought of building a stateless session bean that will be deployed as webservice. The session bean shall connect to the R/3 in order to call some BAPIs. I'd like to use a JCO connection pool. But I'm not sure, where I should create and destroy the connection pool. Are the EJB methods ejbCreate() and ejbRemove() the right ones? If so, my businness methods would just have to get a connection from the pool and call the BAPIs, right? If not, what do you suggest?
Another question: I already deployed a bean as webservice. Since not really knowing how to use the connection pool, I created a bean with one business method that creates a connection pool whenever it gets called. But if I have to change something in the bean so that I have to redeploy the bean I can't call my business method anymore, because JCO cannot load a native library once again, as it is already loaded, This leads to an exception. So I have to restart the complete engine everytime I redeploy my bean. Are there any workarounds for this problem? I'm not sure whether this is connected to the wrong use of the JCO connection pool.
Kind regards,
Lars

JCO connection error:Couldn't create JCOClientConnection for logical System

Hi All,
We are facing a production outage issue.
We have a Federated Portal Network setup where one of our producer goes down automatically (seems on heavy load).
On this Producer server we have 3 Web Dynpro applications deployed and default trace is full with JCO connection error   saying Could   not create JCOClientConnection for logical System: CSVMR_WD_MODELDATA_DEST.
We had issue with max allowed JCO connections so we changed the below mentioned parameters for JCO connection settings in portal:
u2022     Minimum value of JCo Pool Size in total = 80
u2022     Minimum value for CPIC_MAX_CONV per SAP Web AS = 320
u2022     Maximum Number JCo Connections = 160
Please let us know if we are missing on some settings, any help in this regard is appreciated.
Regards,
Priyanka

Hi,
As you have already increased the maximum number of connections/pool size but still you are facing this problem. I would suggest you to check the web dynpro application which might not be able to release/disconnect the JCO connection.
Please check this [Thread|How to close a model object connection for Adaptive RFC?; for more details.

Settings SLD and JCO connection for Java Web Dynpro

Hi BI Gurus,
I'm a Business Intelligence newbye and I'm a bit confused about Web Dynpro configurations.
I try to execute, through Netweaver Developer Studio 7, a simple java Web Dynpro who call the standard Flight List BAPI.
My configuration is: NW 2004s installed on BI server (with java instance and j2EE Server) and Flight List BAPI stored on R/3 ECC. 5 System in another server.
Now, my doubt are:
1) in SLD Data Supplier (J2EE Visual Admin on BI Server) CIM configuration, what are the connections parameter necessary?The BI host or R/3 host?
2)if I set BW system parameters in SLD and in NWDS when I try to run my simple web dynpro an error occour This is the output:
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
3)where can I create new JCO connections?What are the requirements settings?
I am always available for answers about the post!!
Help me please!!
Thanks thousand and sorry for my incorrect english!!

Andrea,
You can Create the JCo destination from Content Administrator. You must login as Administrator.
use the link as
http://<server>:<port>/webdynpro/welcome/Welcome.jsp, select Content Administator->Create JCo Destinations/Maintain JCo Destinations.
Please have a look on the following links regarding creating/maintaining JCo destinations. The are usally asked questions regarding JCo destinations.

HOW to handle JCO connection failure

RFC_ERROR_COMMUNICATION exception...
how do i handle this kind of situation....
what should R3 SHOULD DO..
let's say i have a jco connection
the connection broken during processing...how do i return the error message to the java program
the error include....RFC_SYSTEM_FAILURE ,RFC_ERROR_COMMUNICATION

Yzme,
You have already got answers how to catch this exception.
Next processing depends on application-specific nature of RFC: whether or not call is idempotent, in simple words -- submitting same request doesn't hurt.
This comes from the fact that network failure may occurs when transferring request (hence no background processing performed) or when returning response (hence function already executed).
For idempotent calls there is also an option for automatic re-tries finite number of times. For non-idempotent calls the only option is to display error to user in friendly format.
An idempotent call is a call that can be executed more than once on the server without undesirable side effects. Take for example Create / Read / Update / Delete operations. Obviously, read is idempotent while it doesn't alter data at all. You may treat Delete as idempotent up to certain extent -- just handle "record not exists" gracefully. Create and Update are not good candidates -- re-submitting same request typically leads to serious problems like duplicate entries or data inconsistency.
