Thanks.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:

How to run java program from website?
Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
CheersI rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.

How to launch Java WebDynpro From ABAP?
I have a requirement to launch a Java WebDynpro from ABAP code. Has anyone done this? If so, does anyone know of documentation/sample code or at least an ABAP class/function group I could look at?
Thanks in advance.The webdynpro application can be triggered simply by a URL, so this is really easy in ABAP.
All you need to know is the URL for the WDJ application running on your java engine.
report zrich_0001.
data: url type string.
url = 'http:\www.sap.com'.
call method cl_gui_frontend_services=>execute
EXPORTING
DOCUMENT = url.

How to run java programs from a master java program?
Hello,
I have several java programs which run from the command prompt. I am seeking help with code for starting java programs from within a java program. For example, a program called master.java works something like this:
import java.*;
create connection pool
create variables and result sets
start/run slave1.java (var1, var2);
start/run slave2.java (var3, var4, var5);
start/run slave3.java (var1, var4);
end of program master.java
Each of the slave.java programs will run for up to an hour. I do not want the master.java program to pause for each slave program to stop. Instead, the master program will keep running and multiple slave programs will be running simultaneously with the master program. When a slave program starts, it is on its own. Also, if possible, I would like to have each of these slave.java programs open in a new separate command window, so I can observe each slave program running in separate windows.
Any suggestions for code or helpful documentation are greatly appreciated.
Thank you,
LoganThank you all.
At the bottom of master.java I have successfully started a batch file with these lines:
String jcmd = "cmd.exe /c start c:/data/simulations/MsgViewCount2.bat";
Process proc = Runtime.getRuntime().exec(jcmd);
But I still cannot get a java program to start. Here is one variation I have tried:
String [] cmdArray = new String[2];
cmdArray[0] = "java";
cmdArray[1] = "slave1";
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(cmdArray);
This compiles, and no errors occur, but nothing happens.
Regarding this comment:
Why Runtime.exec? Either make the slaves Runnable or
just call their main() methods.
Oh, I see. Sepearate output. :PNone of the slave.java programs have any output.
Thanks again. -
Hi,
I have a large comprehensive program written in Java and I would like to incorporate the answer in Excel... is there any way I can call the Java program from Excel, execute it and record the answer on an excel spreadsheet?

How to run java class from over the web
hi i ftped my java files to an asp web site.
if it were my local computer i would open up the c prompt and run it with the command java ....
but is there a way for me to execute this java file in the same way
stephen1. the code is a java application.
How may I run this java application on the web server
when I do not have access to the command prompt. I would discuss this with the administrator of the web server. You will need at a minimum a JRE installed on the server and permission to execute commands remotely. If the administrator decides to grant you that permission (which is not likely unless the two of you work for the same company), he should also be able to explain to you how to do that. -

How to use Java code inside WebDynpro-ABAP
Hi,
How to use Java code inside WebDynpro-ABAP.
Could any one provide sample code.
Cheers,
SamHi Sam,
We can't Bring Java Inside the ABAP. Both are running in different Environments.
and also ABAP Codes are runs on BASIS.
-Basis is a middleware between ABAP codes and Ur OS.
-Contains set of programs to load,RUN,intepret the ABAP program..
So Both are Different.

Compiling java code from a running java application
How does compiling of java code from a running java application work?
I found a class: com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class works.How does compiling of java code from a running java
application work?Probably most reliably using Runtime.exec().
I found a class:
com.sun.tools.apt.main.JavaCompiler
but cannot find any documentation of how this class
works.For a purpose. You are not supposed to use this class. With the next JRE release or implementation, it might not exist anymore - it's not part of the standard API. -
