Using jco Service

Hi Friends,
I am unable to use the jco service of PDK as iam getting the 'no such package found' kinda error. Where to lookout for this package in the Tomcat_root Folder?.
I am using Eclipse 2.0 with SAPPDKPlugin and
tomcat-pdk_5_0_5_0 . Tomcat Version 3.3.2. And where to put the com.sap.mw.jco package?.
Thanks in advance.
Regards,
Tamilarasan.

Hello,
If I remember correctly, sapjco.jar resides in the tomcat\lib\apps directory. Alternatively, you can download it from www.service.sap.com/connectors. Make sure it is in your project's build path (classpath) and you should be good to go. I would suggest you ensure alignment of your version of the JCo with the JCo version of the portal server to which you will deploy your iViews.
Cheers,
Mike

Getting SAP data into portals using jco service

Hai friends anybody plz give me the code to get the content from sap into portals using jco.

Hi,
You can download JCo from SAP Marketplace
https://websmp101.sap-ag.de/connectors
With the according zip file some nice examples come along. For using JCO in the portal pleasw see the docu provided by the PDK there should be a JCo topic in the navigationtree.

How to use JCo Provider Service w/Sneak Preview and Test Drive

I have both SAP Web AS Sneak Preview (6.40) and MiniWas 6.20 Test Drive installed on a single system. I have implemented a Java server program which can be RFC called from an ABAP program using JCO.
The only disadvantage to this process is that I must manually run the server program each time I bring up the J2EE system.
I would like to set things up so that when I start the WebAS 6.40 J2EE system, the server function can be automatically registered (if I'm using the correct terminology - not at all sure about that...). It looks to me that I should be able to use JCo Provider Service to do what I want to do, but I don't know how to do any of the session bean creation and I esp. can't seem to find out how to run the J2EE Visual Administrator, which the documentation I've found leads me to believe needs to be used.
Is there a tutorial, or example, that will lead me through this entire process? I have the ABAP calling program working OK, and I have the Java JCo server program working ok - I just want to create something in Java that will operate like a good old C Language function installed as an RFM.
Can anyone help? Is it possible?

Stefan:
Well, I guess I'm stuck at the first step.
As I understand it, I have to use the Visual Administrtor to register the Web AS 6.40 Sneak Preview system as an RFC destination. When I bring up the Visual Administrator, it has essentially two tabs showing: Dispatcher and Server. It's inviting me to define a connection and Login. So, Q1: Is it inviting me to login to the J2EE or the Web AS? Either way, I am never able to login - I get this error:
com.sap.engine.services.security.exceptions.BaseLoginException: Cannot create new RemoteLoginContext
I used all of the NetWeaver sneak preview defaults when installing, and I recorded these:
Type               Account
OS User            Compaq-laptop/J2EAdm
OS User            Compaq-laptop/SAPServiceJ2E
DB User            SAPJ2EDB
J2EE Engine User   Administrator
J2EE Engine User   Guest
Q2: Is it possible to do what I'm trying to do with the Sneak Preview system?
Or am I trying to connect and logon to the Web AS 6.20 Test Drive (I don't think so...)? I used the defaults when installing the Test Drive, and have these users:
BCUSER
DDIC
Is it one of these I should be logging onto?
Also, Visual Administrator wants a port specified on the J2EE Engine connection paramters - what port should I be specifiying?
Can you get me past this dilemma, Stefan? Thanks...

Bapi Call using JCO

Hi all,
Please share your views on the below scenario:
A WD Java app, deployed on WAS and an iView created in portal, is calling a BAPI and works fine when assigned to the role.
Now the same application when viewed directly using
http://<host>:<port>/webdynpro/dispatcher/local/<appname> does not execute the bapi and gives
com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Error connecting using JCO.Client: null
The JCO are using a service user to connect to the backend, so SSO still exist.
Let me know what we could be doing wrong here.
Meanwhile I can check the connection pool to see the property value.
Thanks for your time
Avinash

Hi Prashant
Thanks for your quick response.
The application when accessed directly does not ask for user id/password.
If I set the application property 'authentication' as true, would this authentication be done against UME?
Also since there is no "SSO using logon tickets" why is there a need for issuing a logon ticket?
I will try what you suggested in the earlier post.
Thanks
Avinash

Problem with BAPI_DOCUEMENT_CHECKOUTVIEW2 while caliing using JCO

Hi DMS Gurus,
The above FM is successfully executing and creating a local copy in temp folder of where the FM running using SAP GUI.
But when i call using jco,i am getting some problems.
1. If i execute the FM with default values for http dest and ftp dest, i am getting error saying << c:\temp\....file could not be created.
2. When i changed the HTTP destination to <<SAPHTTPA>, it is executing fm successfully but dont know in which system the file is downloaded.
My client application or xMII server ( where jco service is running ) or ABAP server.
I checked in the first 2,i didn't find.
SAP GUI is not installed in xMII server.
But my requirement is to download to the physical server of xMII ( jco ).
Is this any thing to do with creating http destinations??
If that is the case, can any body help me in creating http destinations..
and i heard something about SAPFTP.EXE ,is that should be some where in client or any servers??
Please help me.
Thanks
Vansi

Vamsi,
As I mentioned in this forum thread, bapi_document_checkoutview2. You have to use the POST action in BLS to communicate with the HTTP Interface of Content Mgmt. directly. The only other alternative is to write your own BAPI to retrieve the content and send it back to xMII via the JCo action (Hint: The data will be base64 encoded and can be saved to the filesystem via the Image Saver action even though it is not an image).

Hi Vansi,
that's correct. BAPIs always require a SAPGUI connection. Therefore I would recommend you to use API function modules instead, because they are more flexible and better to use for background processing. Please see SAP note <a href="https://service.sap.com/sap/support/notes/504692">504692</a>
which contains also some sample programs for these API modules.
Best regards,
Christoph

Without BPM:Call RFC using JCO in interface mapping using java mapping

Hi all
I have a very small scenario where REQUEST from the customer comes via Web Service all i have to do is to read the request using SOAP adapter and call an interface mapping(lets say the name is IM_TEST) inside which there is a JAVA MAPPING program written which will call an RFC in CRM using JCO.
Now this was really simple and i cud test the Interface mapping successfully, but the problem is when loading the scenario in integration directory i have certain things to do
1. to set the SENDER AGREEMENT which i did correctly
2. set the RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT now here i am stuck because there is no receiver in my case as the RFC is called inside the mapping only.
can i call one more message mapping in IM_TEST which will write file onto the XI directory and then in RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT i can mention the reciever as FTP.
I tried it but i gives the following error
Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_MM_TEST_WRITE_FILE: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Parsing an empty source. Root element expected!
Please help me how to complete the scenario so that customer can run it end to end.
<REMOVED BY MODERATOR>
Edited by: Prateek Raj Srivastava on May 12, 2010 1:44 PM

Stefen
What do i do then...actually this is the project requirement. They want a very fast response from PI and thats why they wnt us to omit BPM and the Graphical mapping from the scenario.
I am able to test the interface mapping which calls the the Java mapping inside which there is an RFC call, but i cannot implement it end - to - end as there is no receiver business system in this case. The only business system i have is the SOAP sender.
I am really troubled now, please help me with a solution.
Is there any other possible way through which the process can become very fast whic hcan meet their requirement.

How to use JCo from IPC 5.0

Hi,
We just upgraded CRM from 4.0 to 5.0, and now I´m trying to do the necesary changes in the pricing formulas, but there´s one problem.
With IPC 4.0 we could use JCo to make calls to R/3 4.6c to retrieve additional data (performance not an issue), but with IPC 5.0 this doesn´t seem possible any more. Could anyone please let me know how can I call a RFC from IPC 5.0????
Thanks,
Jonatan Urfalino

Correct, inside IPC 5.0 the only thing you can find is a parallel JCo implementation that is not a standard one, but just a fachade that SAP made to comunicate from java to ABAP using shared closures. This JCo cannot (as far as I know) be used to comunicate to other systems, only to the host on which IPC is running.
The solutions:
1) If you want to comunicate to an old R3 system (that is my case) you can use the internal JCo to call a BAPI in the abap stack wich internally calls the bapi in the other system. the performance is not so bad because the first call is made with shared closure within the same system,and the second one is a standard RFC call.
2) If the destionation system is also an ECC 6.0 or any that supports web services, the solution proposed by Leonardo is excellent indeed! Except for one issue, that Leonardo already mentioned already: the web services's performance.

Using JCo : IDoc to XML and XML to IDoc

Hey guys,
I need some guidance on Creating an xml file out of an IDoc using JCo and vice versa.
Can anybody please provide with the code samples or any kind of documentation on this topic.
Points will be rewarded
+| Eleana West

Hi,
what you are looking for is the sapidocjco.jar. You can get if from the service marketplace and it comes with a couple of example Java code which shows how to implement it. You will also need the normal JCo jar to use the sapidocjco.jar.

Hi Kishore
Going by the error, there is some attribute which does not have a value at runtime. Hence you must be getting the Null Pointer Exception.
Can you let me know the following so that i could be able to help you further.
1. Name of the SLD connections. Have you tested them
2. Where are you making a call to the BAPI. Is it inside the wdDoInit() method.
3. How are you passing the parameters to the BAPI_FLIGHT_GETLIST.
I have done this example and there is no problem. If you let me know the above points i would be able to help you further.

Ravi

Calling BDC from Java using JCO

Hello Everyone,
Is it possible to call a BDC from Java program using JCO ?

Are you serious with that question? Did you try to build the web service client before? Because this is exactly the same. Try to find "building web service clients" instead "Calling BPEL from java". By default (probably) every BPEL process has both WSIF and SOAP end points, just use correct WSDL address.
