Asyncronic JCO RFC call from JAVA to ABAP

Hi,
Please could you provide a sample java code to establish JCO RFC call to ABAP?
Thanks.

Hi Denis,
Import the model In NWDS for ABAP for RFC.
Please check here [Accessing ABAP Functions using the Adaptive RFC Model |http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a00f7103-6790-2a10-ac9c-fcac7c5b18a3?quicklink=index&overridelayout=true]

RFC call from java webdynpro

Hi,
I'm creating a Java Webdynpro where I call RFC's from SAP.
For the images in the webdynpro, I call the standard SAP function 'CVAPI_DOC_VIEW'
When I execute the function in SAP, I get the url to the contentserver with the correct image.
After calling the same function in my Java Webdynpro, the url is empty.
I've checked the importing parameters after calling from webdynpro and SAP and they are the same.
After debugging, I saw that the function 'CVAPI_DOC_VIEW' is the problem. He's exporting an empty url after calling from the webdynpro.
Does anybody knows the possible fault and solution for my problem?

I'm not an ABAPer but the last time I've dealt with DMS from Web Dynpro an ABAPer wrote a custom function that gets the file content (XSTRING) by sending DMS parameters (documenttype, documentnumber, documentversion, documentpart).
After getting the XSTRING from my Web Dynpro Java, I convert it to byte[] and created URL by using WDResourceFactory.
Hope it helps...

Duration of an Abap Function call from Java using Jco3

Hi guys!
I would like to use this discussion to get some refernces of the duration Timespan of an RFC call from Java to SAP. At the moment, i need at last about 200ms to call the Abap function. I'm just using one simple import and export parameter (so no deep structures). I think that the reason for my poor performance is, that the Java Tool and the SAP instance are not in the same network. So, i hope some of you have some data, how fast an RFC call from Java using Jco can be executed.
greetings, Hannes

Hi Hannes,
I think you have already got the answer to your question - the network set-up you have is probably the bottleneck. Whenever I've worked with Java <-> ABAP and they are in the same network, I've had no performance problems at all.
Does your RFC contain any complex logic or business processes? Are you able to try and call something that does nothing, say it just accepts an input string and returns it straight away as an export. Do you have any scope for testing with your Java tool on the same network as the SAP system?
Cheers,
G.

RFC Call from ABAP (R3) to Webdynpro EP

Hi experts,
I have a requirement to initiate a call from an ABAP program on R3 to a standard Portal (Webdynpro) API. Does anyone have any experience with this?
I understand that normally Portal (Webdynpro) applications will make the RFC call to ABAP via the established JCO connection. However there's very limited literature elaborating how the call can be made in the other direction i.e. from ABAP R3 to Portal
Anyone, please kindly advise how, if this can be done. Many thanks!
Best regards,
Lionel

Hi,
I'm trying to make a RFC call from the ABAP program to a built in Java method residing on EP. It is part of a suite of methods provided by the UME engine.
Typically a call is made from a webdynpro program to a SAP ABAP function module. In this case, I'd like to make a call from the SAP ABAP report to the EP method.
Best regards,
Lionel

Making an RFC call from within the VM container

Hi all,
since a long time I am searching for information on how to implement an RFC call from within the VMC. The problem is that we have implemented several (p)functions in ABAP and we need to implement them in JAVA.
Now I am searching for a way how to just call the already existing pfunctions???
Is it possible to read CRM DB tables too?
Thank you in advance
Boris

Hi Freeto,
This may be due to the Network Failures.
If you have triggered a job then because of the Network fluctuations the system may not respond properly and cannot execute the job.
So, this is the cause for the failure.
Hope you understood.

How can i measure BAPI runtime which has called from JAVA

Hi abapers
how can i get run time for BAPI called from JAVA through JCO.
i know that i can use SE30 from ABAP by executing from SAP.
may be ST05 useful for me i did it but when display trace
i am getting big list by seeing this list i am not able to find the runtime for that BAPI.
please any one can explain
reagdrs
ramesh

Hi Ramesh,
Irrespective of whether the call is from an external system or within sap, the bapi will be executed in R/3 only.
So, you can safely measure the runtime using se30 only.
If it is taking more time when called from JCo , then you can be sure that the problem is not with SAP and is actually due to the JCo connectivity with R/3.

Ravi

Best approach for RFC call from Adapter module

What is the best approach for making a RFC call from a <b>reciever</b> file adapter module?
1. JCo
2. Is it possible to make use of MappingLookupAPI classes to achieve this or those run in the mapping runtime environment only?
3. Any other way?
Has anybody ever tried this? Any pointers????
Regards,
Amol

Hi ,
The JCo lookup is internally the same as the Jco call. the only difference being you are not hardcoding the system related data in the code. So its easier to maintain during transportation.
Also the JCO lookup code is more readable.

Invoke MII Transaction thru RFC Call from SAP

Hi,
We want to get the data from Oracle DB table thru MII (12.0.2).
We need to use RFC call from SAP to MII.
Is it possible to invoke the MII transaction thru RFC by setting in Message Listener?
We have used iDoc messages but not tried with RFC.
How to do that?
Regards,
Senthil

I feel MII doesn't have anything equivalent to RFC in ECC. You may try web services in an ABAP program
Hope the article below helps you

Asynchronous RFC call from R/3

I need to make an asynchronous RFC call from R/3. I receive an error message in R/3 stating that my RFC destination can only be of type I (Internal) or type 3 (R/3 system). In order for it to reach XI I need it to be of type T (TCP/IP). Any help would be appreciated.
Here is the function call.
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK' starting new task 'SESSION1'
   destination 'RFC2XMBSERVICE'
      EXPORTING
           MSG_TYPE            = msg_type
           ORDER_HEADER_RETURN = order_header_return
      TABLES
           RETURNCODE          = i_return.
the RFC desitnation RFC2XMBSERVICE is of type TCP/IP which by default makes it synchronous.
Thanks,
Jim

hi,
have you tried:
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK'
in background task
destination 'RFC2XMBSERVICE'
EXPORTING
MSG_TYPE = msg_type
ORDER_HEADER_RETURN = order_header_return
TABLES
RETURNCODE = i_return.
commit work.

How to pass variable from Java to ABAP in BSPs

Hello experts,
taking into account the two environments (browser and server) I need to pass information from Java to ABAP.
After seen this link: Re: View Refresh
I have tried the next:
HTMLB: <input type="hidden" name="myFlag" value="">
ABAP:   DATA: lv_height TYPE STRING.
JAVA:   var intXo = readCookie("XEix");
JAVA:   if ( intXo == 900 )
JAVA:   else if (intXo == 725 )
ABAP:   lv_height = request->get_form_field( 'myFlag' ).
ABAP:   IF lv_height EQ 'X'.
ABAP:     TRAYTAREAS_P = 'TRUE'.
ABAP:   ELSE.
ABAP:     TRAYTAREAS_P = 'FALSE'.
ABAP:   ENDIF.
"document.all.myFlag.value" gets the correct value according the condition, but the ABAP code does not recover this value (lv_height is always initial).
Can you help me with that? I'm not able to see where is the mistake...
Exist any alternative way to recover in ABAP an JavaScrip value?
thanks in advance.

Hi Raja
I think you are appointing to this posted solution:
HTMLB: <input type="hidden" name="myFlag" value="">
ABAP: DATA: lv_height TYPE STRING.
JAVA: var intXo = readCookie("XEix");
JAVA: if ( intXo == 900 )
JAVA: else if (intXo == 725 )
ABAP: lv_height = request->get_form_field( 'myFlag' ).
ABAP: IF lv_height EQ 'X'.
ABAP: TRAYTAREAS_P = 'TRUE'.
ABAP: ELSE.
ABAP: TRAYTAREAS_P = 'FALSE'.
ABAP: ENDIF.
but it doesn't work. Can you detect if there is any evident error there or the process is right?

Excel sheet generation through RFC call from a BSP application

Hi,
I am calling a RFC FM ( in R3) in Event handler 'OnInputProcessing' of a BSP application in a SRM server.
That function submits a report program which geneates a excel sheet using download FM . Excel sheet is not getting generated.
But when i am calling this RFC FM (in R3) from a report program ( in srm server)
this is generating an ecel sheet.
I want to have call RFC from BSP application.
I tried the way of submit a program ( which contains RFC call) from BSP application ,but it is also not generating excel sheet.
My ultimate AIM is to generate excel sheet by trigerring CALL or submit from BSP
application.
can any one propose solution for it.
Useful answers will be rewarded.

Hi,
Which FM is it. I guess that the download generated is a SAP gui oriented solution, which will never work in a web environment

RFC call from a Windows Service

Hi All,
I have created a simple windows service which is making an RFC call to R/3 system. This is not working. Whereas the same piece of code written in a windows application projects(exe) works properly. Does anyone had similer issues working with Windows services ? Is it a known issue of RFC calls from windows service ???
Thanks & Regards
Ganesh Datta

Hi Juergen,
After I put the debug statements I figured out that connection to R/3 system is unsuccessful.
I am using the SAP .Net Connector 2.0. I wrote a windows service which is manually started. Withing my service I am using Single sign on to connect .This is what was causing the problem. If I disable Single sign on and supply userID and password then connection is successful and also subsequent RFC calls.
I guess within windows service Single sign on does not work.
Thanks for your reply
Best Regards

RFC call from XI ABAP stack to XI

Hi All,
I have a RFC in the XI ABAP stack. When I created an RFC connection (TCP/IP) connection on the XI ABAP stack through SM59, and tried test connection, it is not working. Am I doing something wrong here? If I am trying to call XI JAVA stack from XI ABAP stack do I need to use an RFC adapter or is there any other way of calling the XI JAVA stack?
Thanks,
Geetha
Edited by: Geetha on Feb 5, 2008 12:18 PM

XI ABAP Stack and JAVA Stack are connected using the JCO connections, if you want to call the RFC in the ABAP stack of XI using the RFC adapter which sits on the JAVA stack
1. whats the purpose of creating the RFC on the XI ABAP Stack, is it a business stack?
2. the created RFC destination in the XI ABAP stack should work if it is properly created...check the SAPHostname, gateway information? and also the registred program id.
3. use the same registred progrram iD in the RFC sender adapter and actiavte it then it will work.....
