Can i call java program from VC++ code...... Urgent!

hi,
I have VC++ code.
I want to run java program from VC++ (SDK).
Can I call it?
plz help it's urgent....
thanks in advance...

We do it all the time using the JNI invocation API (this is actually how the java.exe application works).
Here's a tutorial I just found (not sure how good it is, but it should get you going):
http://www.inonit.com/cygwin/jni/invocationApi/
One note: If you are going to be invoking the JVM from different threads in your native app, there is some special handling you will have to do - the above tutorial doesn't address this scenario (a dig through the JNI docs should help with that one, though).
Cheers,

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

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.

Calling Java programs from Oracle Stored Procedure

Is it possible to call Java programs from Oracle stored procs? If possible Can this be used to exchange data from other applications? Is there a better method/feature in oracle for doing data exchange with other apps?

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

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:

Can we call java jar from ODI?

Hi All,
Can we call java jar from ODI? if yes please suggest how?
Regards,
Satish

This is an excellent article from Uli.
One reason, I dont like this approach is that is mandates to copy the .jar file to the driver folder and restart the agent.
Think of a scenario where there are several developers in love with Java and want to place the jars in the drivers directory.
This is a maintenance nightmare for the admin and would clutter up the drivers directory.

Calling java program from PL/SQL code

Dear,
How to develop and call a java program from PL/SQL code?
What about if this program will call other java programs?

Call Java Program from ABAP Program

Dear all,
In our scenario, we need to let ABAP call services provided by a standalone Java program. From online help I found some overview introduction and I'd make the called program a registered program in a RFC with type "T" (TCP/IP Connection). Can anybody give some concrete documentation? A step-by-step guide would be greatly appreciated.
Best Regards

Can we call Java class from LiveCycle Process?

hi..
I have a general query, is it possible to call customeized java class from Workbench Process?
I found dat we can invoke a web service... is there some operation like that for calling a java class...
Thanks and Regards,
Ambika

Yes.
You can use the Script service and put your Java code in there
Or build your own component, which is really a Java pojo, and deploy it to LiveCycle. See http://livedocs.adobe.com/livecycle/8.2/programLC/programmer/help/000934.html.

Calling Java Services from ABAP code

Hi,
How to call Java services (not web service) from ABAP code?
I have a requirement where JAVA team has developed some services that can be called from URL or from a Java application.
Ex: when this URL is executed,
http://localhost:8080/artemis7_802/triton/mycompany.remoteFunctions.RequirementsList.a7x?requestid=3023&requestname=I6PRAO1&skill=SAP&skill=JAVA
It returns a XML file on browser.
And I have no idea about the 2nd way i.e. from Java application!
Now, how can ABAP call these java methods?
I heard that something can be done via maintaining RFC destinations in SM59 to call Java services? Can this be done with my requirement?
Please help.
Thanks and regards,
Amey

Calling java program in bipublisher

Hi,
Like we have datamodel types in BIPublisher as SQL Query, Webservice, Answers, File etc,, Can we call java program through bipublisher.
The requirement is:
A java program will generate BARCODE image based on the customer number given.
We need to create a template in bipublisher which shows the customer name and that barcode image and other details.
We have calling javaprograms in ibots in analytics, is there any such thing in bipublisher.
Thanks.

You can call PL/SQL programs from OWB either by defining transformations or as expressions. From PL/SQL you can call a java stored procedures in the database as follows:
1. Define the java stored procedure. For example, let's suppose that you store the following Java class in the database:
import java.sql.*;
import oracle.jdbc.driver.*;
public class Adjuster {
public static void raiseSalary (int empNo, float percent)
throws SQLException {
Connection conn = new OracleDriver().defaultConnection();
String sql = "UPDATE emp SET sal = sal * ? WHERE empno = ?";
try {
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setFloat(1, (1 + percent / 100));
pstmt.setInt(2, empNo);
pstmt.executeUpdate();
pstmt.close();
} catch (SQLException e) {System.err.println(e.getMessage());}
2. The class Adjuster has one method, which raises the salary of an employee by a given percentage. Because raiseSalary is a void method, you publish it as a procedure using this call spec:
CREATE PROCEDURE raise_salary (empno NUMBER, pct NUMBER)
AS LANGUAGE JAVA
NAME 'Adjuster.raiseSalary(int, float)';
3. Call procedure raise_salary from an anonymous PL/SQL block, as follows:Long postings are being truncated to ~1 kB at this time.
