How i can call java program in VB2005 ?

Hi members...
Please...please...please...
If any one now how i can call java program in VB.net program and open it ,please i want now the way to do it by details and by examples and step step to do it ,,..
thanks ...

If your server does not return to the command prompt, write a java programm which starts your server and returns to the command prompt.
An example for an application like this:
import java.io.IOException;
public class StartApp
public static void main(String[] args)
if (args.length > 0)
StringBuffer cmd = new StringBuffer();
for (int index = 0; index < args.length; index++)
cmd.append(args[index] + " ");
try
Runtime.getRuntime().exec(cmd.toString());
catch (IOException ioe)
System.out.println("Error: command not found: " + cmd.toString());
else
System.out.println("Error: missing arguments");
An example for starting your server with that programm:
/usr/bin/java -jar ./StartApp.jar /usr/bin/java -jar ./myServer.jar
It works. Have fun.

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'.

     ECHOTEXT = ECHOTEXT

How to make a java program, that can be used by c++ application

I'm developing a Java web application (WEBapp), but I have also a c++ program.
C++ program must use WEBapp method to communicate on the web.
How to make a Java public function that accept value, elaborate, then return the resul to c++ application?

jschell wrote:
You have C code.
You have Java code.
The two must communicate.I have a c++ program, and a Java program.
C++ program wants to communicate on the web (send text), and I'm trying to add this functionality to it creating a Java program.
NOW THE PROBLEM? How c++ program can use java-program (in local) to send data on the web?
You can just JNI to communicate either from java to C++ or from C++ to java. That is direct communication in that there is a single process involved. Thus you will no longer have a java application and a C++ application but rather a single application.I don't know JNI, i found http://java.sun.com/docs/books/jni/ and I think is too difficult to implement?
You can use files or sockets to communicate. Using sockets allows for any number of additional protocols including the previously mentioned web services. Those methodologies would allow more than one application to exist.I developed yesterday a java-side-interface using socket (in local host 127.0.0.1). So the c++ program must write or read to/from the socket to comunicate to java (then the java program send data on the web).
Finally it might be the case that you have a C++ application which you cannot modify. In that case then you MUST use whatever input/output mechanism that it supports. There is no choice. And until you have fully determined what those mechanisms are it is pointless to discuss a solution.I can modify the application, but I don't have developed it. The c++ application use a third-part dll (taken from SKYPE) to comunicate on the web: I have to remove the dipendence from this dll, and add the java program: java program must substitute the dll. It must be non-invasive to the c++ program. DLL calls can be "send(data)" or "receive(data)" or similar.
For this do you think that JNI is a must, or I can use soket on local host?

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 make a Java program that recognises a function of two variables...

How to make a Java program that recognises a function of two variables to assign values to that?
First I will give an example and then do the question.
Ex1.
We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
To build the graph of this function attach values to 'x' to find the values of 'y'
And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
We can use any numbers, but arfer interval [-3.3]
X | y = x ^ 2 + 1
-3 | Y = (-3) ^ 2 +1 = 10
-2 | Y = (-2) ^ 2 +1 = 5
-1 | Y = (-1) ^ 2 +1 = 2
0 | y = (0) ^ 2 +1 = 1
1 | y = (1) ^ 2 +1 = 2
2 | y = (2) ^ 2 +1 = 5
3 | y = (3) ^ 2 +1 = 10
We then ordered the pairs:
(-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
Tabem that can be represented by a table:
X | y
-3 | Y = 10
-2 | Y = 5
-1 | Y = 2
0 | y = 1
1 | y = 2
2 | y = 5
3 | y = 10
Now I begin to explain my doubts.
See this program:
Ex2
* To change this template, choose Tools | Templates
* And open the template in the editor.
Encontrando_o_valor_de_y package;
* @ Author des Soldat Gottes
Import javax.swing.JOptionPane;
Public class (Main
* @ Param args the command line arguments
Public static void main (String [] args) (
Int x, y;
String x1;
X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',"); / / receives a value for the function y = x + 1
X = Integer.parseInt (x1); / / tranforma String in int
Y = x + 1; / / receives the value of 'x' and calculates' y '
JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
/ / Displays the value of 'y'
System.exit (0);
We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',");
The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
The question is: would it be possible to come to a function?
Ex: the program ask: DIGITE THE FUNCTION?
The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
And then to find the values of the x and y launch a table.
It would be possible that?
By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
I hope it has been easier to understand my doubts now.
Thank you for your attention!
God bless!

Thanks for the explanation, could understand what fly said.
But as it applied to a program?
How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
Strip out the spaces
Split the String on "x^"
That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you.

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.

How to run a java program in another folder

Hello!
I want to run for example the java class file in the path ./sourcecode/javafile.class. It works fine if I do the following:
cd sourcecode
java javafile
but it cannot work if I do:
java sourcecode/java
The error it outputs is NoClassDefFoundError.
Can someone tell me how to run a java program in another folder
thanks a lot.

You need to specify the classpath using the -cp flag when running. so instead of
"java sourcecode/javafile"
Try
"java -cp sourcecode javafile"

must copy certain fields into another database. When I see "whenever thiere is a change to certain fields" I tend to think "triggers" - but maybe this won't work for you 'cause of the "another database" part. And the fact that triggers are inherently evil.

Is it possible to run a Java program as a windows
service? And if so then how would you go about it? I'd hit Google - there're a couple ways to do this.

Also,...if I were to use one of those programs which
can make an .exe of a Java program, then do you still
require the JRE to be on the machine? It depends on how you did the conversion. If you compile to native then no, if you just wrap up a JRE then yes.
Why I ask is
that I occasionally get asked to do small development
projects for my company, but we are a microsoft
partner and therefore do all the development in C#
and the like. So I would like to just implement as
many things in Java as I can, just to show everyone
that Java can do exactly what C# can do. But its
difficult to convince people of this since I always
require the JRE and they dont. Of course, they require the .NET framework and you don't. And last I looked that thing was around 23 Meg.

HELP!!! How I can call to EJB from another EJB??

I have two EJBs, for each EJB I have a jar, how I can call to EJB jar to another???
I have tried the following, in the first EJB I have import the second EJB jar and call it with context, lookup, PortableRemoteObject etc.. but the instruction lookup not find the second EJB reference.
The name in the lookup instruction is the JNDI name of the second EJB but not find a reference to it.
Please help me!!! Thanks!!

ok.. Here it goes.. I am writing a sample code..
public class EJB1LogBean implements SessionBean {
// test is a method of stateless session beam
public void test ( TestVal val )
throws RemoteException{
try {
EJB2LogHome ejb2Home= (EJB2LogHome)getHome("java:comp/env/ejb/EJB2LogHome",1);
EJB2Log ejb2Log = ejb2LogHome.create ( val );
} catch ( CreateException e ) {
     System.out.println("Create Exception occurred ");
     e.printStackTrace();
     } catch ( RemoteException e ) {
     System.out.println( "RemoteException Occured");
e.printStackTrace();
     throw new RemoteException () ;
     } catch(Exception ee) {
ee.printStackTrace();
private EJBHome getHome(String jndiName,int type) {
try {
Context context = new InitialContext();
Object ref = context.lookup( jndiName );
switch(type)
case 1:
EJB2LogHome ejb2LogHome = ( EJB2LogHome )
PortableRemoteObject.narrow( ref, EJB2LogHome.class );
return ejb2LogHome;
} catch ( Exception e ) {
e.printStackTrace();
return null;
}//EJB1LogBean ends
Here as you can see, EJB1LogBean(session bean) is calling a second EJB, EJB2LogBean (entity bean). TestVal is a sample value object passed. It is plain java class and can vary from app to app and it has got nothing to do with ejbs.
"java:comp/env/ejb" is a J2EE standard and while getting a home interface, you have to append the home interface class name to "java:comp/env/ejb". Here I am passing "java:comp/env/ejb/EJB2LogHome" and "1" to getHome method, whose job is to get a reference to a home interface. getHome method is a local method. "1" is passed just to give a flexibility to getHome method as you can have more ejbs to invoked. In that case, you can go on adding different case statements for 2, 3 etc.
The only thing you have to keep in mind is that your deployment descriptor for EJB1LogBean will contain the entires for both the beans i.e. for EJB1LogBean and EJB2LogBean. This is because EJB2LogBean is wrapped by EJB1LogBean.
Hope this helps.
Please let me know if you need anything more.

Can two java program write to the same port by fetching data from different

can two java program write to the same port by fetching data from different ports, if yes is thing possible for a 3rd program to get all data (is there any data loss or collision)
how is this possible

can two java program write to the same port by fetching data from different portsTwo java clients can connect to the same server port and they can both write to it. However the server will see the connections as two separate accepted sockets.
