Call a Java file from ABAP

Hi,
I would like your help in identifying a mechanism in calling a Java Program from an ABAP program. The requirement is that I need to pass enough parameters(possibly in a single object like a table) and fetch that in a Java Program residing in a jar in the J2EE engine. The possibility of this java file interpreting this incoming object and also be able to return something to ABAP which can eventually be printed on the screen needs to be known.
I also would like to validate an assumption of mine which is that, the jar(the receipient java file) file needs to be put under the directory
"\usr\sap\SystemID\instancenumberj2ee\deploying\lib"
Appreciate your time and effort in helping me with this.
Regards,
Sam.

i am not sure about
I also would like to validate an assumption of mine which is that, the jar(the receipient java file) file needs to be put under the directory
"\usr\sap\SystemID\instancenumberj2ee\deploying\lib"
but for your case what you could do is, on the java side get developed a jsp page which will receive data and use the jar to proces and return the results as xml. once thats done.
from abap you can use cl_http_client class to call this jsp page to pass parameters and get the processed results from jsp page.

Call a Java Function From Abap

Hi, I need to call a java function from ABAP, I have a WAS 640 to deploy the module.
I have found this tutorial...
[ABAP calls Java via RFC|/people/thorsten.franz3/blog/2008/11/21/abap-calls-java-via-rfc-1-introduction]
The problem is that it uses a newer version of WAS and it implements EJB 3.0 wich only works on Java 5, but my WAS has java 1.4.2.
Anyone knows how to adapt this Blog to a WAS 640 version ?
Or Perhaps there is another way of doing this, maybe publishing my function as a web service.
Regards.
Mariano.

Why don't you expose your Java functionality as a Web Service and consume it in ABAP program. That should be much easier and the web service can be used in other places as well.

CALL A JAVA PROGRAM FROM ABAP -- NEED HELP

Hi all,
Can somebody tell me how to call a java xml code from an ABAP program? First let me know if at all, is it possible to call a java program from SAP that is from an ABAP executable progam?
Please suggest me in this. All your inputs in this is valuable to me and highly appreciated.
Thanks in advance,
Vaishnavi Varadarajan

Hi,
Previous explanation i gave is not correct.
ABAP web services expose the function modules outside R/3, so that other technologies like Java can consume that webservice and read the data in R/3 using the function module.
For your requirement, create a Java web service to read the XML. Consume this webservice in ABAP. This way you can read the XML from ABAP.

Pabi,
Using the RFC connection,we can establish a link between Java and SAP.
Afterwards,hope we can call Java program from ABAP.
Below is the sample piece of code to establish RFC connection(link) between Java and SAP.
DATA: REQUTEXT LIKE SY-LISEL,
      RESPTEXT LIKE SY-LISEL,
      ECHOTEXT LIKE SY-LISEL.
DATA: RFCDEST like rfcdes-rfcdest VALUE 'NONE'.
DATA: RFC_MESS(128).
REQUTEXT = 'HELLO WORLD'.
RFCDEST = 'JCOSERVER01'. "corresponds to the destination name defined in the SM59
CALL FUNCTION 'STFC_CONNECTION'
   DESTINATION RFCDEST
   EXPORTING
     REQUTEXT = REQUTEXT
   IMPORTING
     RESPTEXT = RESPTEXT
     ECHOTEXT = ECHOTEXT
   EXCEPTIONS
     SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
     COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
IF SY-SUBRC NE 0.
    WRITE: / 'Call STFC_CONNECTION         SY-SUBRC = ', SY-SUBRC.
    WRITE: / RFC_MESS.
ENDIF.

JCo Outbound( calling Java Function from ABAP )

HI,
I want to call a JAVA function from ABAP.I have installed the JCo toolkit and included the sapjco.jar file in the classpath of my system.
When i execute the program(Example5.java,provided with sapjco.zip) from the command prompt,it is working fine,the server listens to the calls made from ABAP via RFC destination.
But if i copy the same program in NWDS in a JAVA project,to run it from there as JAVA application,after including the sapjco.jar file in the project JAVA build path,i get the following error,marked by a red cross ,at the head of the program,even before i run it.
This compilation unit indirectly references the missing type com.sap.jdsr.writer.DsrIPassport (typically some required class file is referencing a type outside the classpath)
What changes do i need to make,to run it from NWDS?
I tried to include the sapjcorfc.dll file along with the sapjco.jar in the java build path,but it doesn't help.
Please tell how to solve this issue?
Regards,
Siddhartha

hello sid,
which jco version are you using?
are you using the same jco lib when running in command
line and in nwds?
if you are, try checking the order of the your classpath.
your jco lib (which you are using in command line) should
come first in order prior to the default libraries in your project.
regards
jo

How can I call a java object from Web dynpro ABAP application?

I made Web dynpro ABAP application and posted it to SAP EP.
For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
Is there anybody who experienced this kind of java interface issue?
I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,
Raymond, ABAP Consultant

if you have jco configured, then you can make calls to java api from ABAP .

Call IDM Rest API from ABAP

Good day experts,
We have a requirement to add privileges to users in IDM via a call from a SAP GRC system
Does anyone have example code of such a call in an ABAP function module?
Thanking you in advance,
Johan Kriek

Martin,
Thanks for your reply.
I tried the Web Service way of doing it, seems to be working alright but again it comes with all the security issues and all around the Web Service.
I am exploring the use of JCO RFC Service provider, to call a JAVA program from ABAP. Hopefully that should work.
Thanks again.

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks
Prince

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:
