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.

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.
<b>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)</b>
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.

IP - Is it possible to call exit planning function from ABAP Report..

Hi All,
Greetings.
Is it possible to call exit planning function from ABAP Report (t-code SE38) ? Or I mean is not limited only to be called from ABAP Report, perhaps from BSP / Web-Dynpro / Function Module.
If somebody here has been doing it before, I'm keen to ask to kindly share it. Particularly how to call and transfer data to that exit function.
Or if somebody has done in BPS, appreciate if it can be shared too .
Thanks a lot and have a good day,
Best regards,
Daniel N.

Hi.
You can achive this as suggested by Mattias in your previous post.
Lets say you have next data structure:
CostCenter | Amount | PercentForDistibution |
Create input ready query in this format. Restrict cost center by variable type range.
Create WAD with analysis item.
When you run web page you enter range of cost centers (lets say you will enter 101004 to 101010).
I assume you have data only for 101004 in your cube (lets say 1000).
You will see only one record in your webpage.
CostCenter | Amount | PercentForDistibution |
101004       | 1000     | NOTHING
When you create WAD in analysis item properties set "NUMBER_OF_NEW_LINES" to lets say 1 (so in WAD you will see always one blank line for entering new data).
Just add 6 new records:
CostCenter | Amount   | PercentForDistibution |
101005       | NOTHING| 10
101006       | NOTHING| 30
101007       | NOTHING| 20
101008       | NOTHING| 25
101009       | NOTHING| 5
101010       | NOTHING| 10
Then run planning FOX function like this:
FOREACH Z_COST_CENTER.
IF {Amount, Z_COST_CENTER} <> 0
Z_AMNT_TO_DISTRIBUTE = {Amount, Z_COST_CENTER}.
ENDIF.
ENDFOR.
FOREACH Z_COST_CENTER.
IF {PercentForDistibution Z_COST_CENTER} <> 0.
{Amount, Z_COST_CENTER} = Z_AMNT_TO_DISTRIBUTE * {PercentForDistibution Z_COST_CENTER}.
ENDIF.
ENDFOR.
It is not perfect FOX, but as an idead, it should work.
Regards.

Calling a java function from xquery

Hello,
I'm pretty new to ODSI and xquery, so forgive me if what I'm asking is too trivial, but I need to find a way to call a java function from inside xquery. I know xquery can do this through external functions, but can't find any example on how the query prolog declaration should be, nor how the function should look like. Could someone enlighten me?
Thanks,
Pedro Ivo

You can do this 2 ways that I know of (Mike probably has more ideas too)
1. Register an inversion function:
[How to use an inversion function|http://download.oracle.com/docs/cd/E13167_01/aldsp/docs32/dsp32wiki/Using%20Inverse%20Functions%20to%20Improve%20Query%20Performance.html]
2. Create a physical data service based on a java function. I have used this approach for both custom JDBC database operations and straight Java processing, with pretty good results.
Good luck,
Jeff

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.

Calling a Java Function from PL/SQL

Hi,
I would like to call a Java API from a java class residing on the middle tier ($OA_JAVA)

Documentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
says JPublisher can publish records too.
But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
PACKAGE "COMPANY" AS
type emp_rec is record (empno number, ename varchar2(10));
type emp_list is varray(5) of emp_rec;
type factory is record (
name varchar(10),
emps emp_list
function get_factory(p_name varchar) return factory;
END;
then I see <unknown type or type not found> at sql or java files generated. Any ideas?

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 <i>table</i>) 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\<i>SystemID</i>\<i>instancenumber</i>j2ee\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.

Is it possible to call a java function from plsql?

I have a plsql script which loads data in to a table. One of the fields is a notes field. I would like to use advance offerings of java to manipulate the data before inserting. Is there away I can pass the data to a java function and have it return the manipulated data?
Thanks
Aaron

You can use java stored procedure to call java function from plsql.
1. Create a java class with a static function(which will be called from plsql).
2. Compile and load the class into database using LOADJAVA command.
3. Create a wrapper stored procedure or function in plsql which calls the above java function.
4. Access this plsql procedure like normal database procedure. This will invoke underlying java function in which you can do all the processing and return result.
Refer this url for help on implementing above steps :

Type Mismatch error while calling a Java Function from Visual Basic 6.0...

Hi,
I'm having a problem in calling the Java Applet's Function from Visual Basic. First, I'm getting the handle of the Java Applet and components of it using "Document.Applets(n)" which is a HTML function. I'm calling this function from Visual Basic. My code is something like this...
' // Web1 is IE Browser in my Form.
Dim Ap,Comp
Dim Bol as Boolean
Bol = true
Ap = Web1.Document.Applets(0).getWindow() ' \\ Gets the Parent Window.
Ap.setTitle("My Java Applet") ' \\ Sets the Title of the window.
msgbox Ap.getVisibility() ' \\ This will return a Java boolean ( true or false )
Ap.setVisibility(Bol) ' \\ Function Syntax is : void setVisibility(boolean b)
Here in my code , i'm able to call any function that which accepts Integer or String but not boolean. So, i m facing problem with Ap.setVisibility() function. It gives me a "Type mismatch error" while executing it. Can you please tell me a way to do this from Visual Basic !
I'm using Visual Basic 6.0, Windows 2000 , J2SDK 1.4.2_05.
Please help me Friends.
Thanks and Regards,

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.

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,

what could be the reason.
This is my html.
I got this from this forum only.
My applet is accessing the system property "user.home".
I ran it in IE
