Acertijo Java - SAP

[Toko]

Mira este es un ejemplo de conexion desde JAva a SAP que baje hace en la red, no recuerdo de donde, pero solo tienes que modificar con los datos de tu sistema

client = JCO.createClient( " ", // SAP client
" ", // userid
" ", // password
" ", // language
" ", // host name
" " ); // system number


codigo de ejemplo:

package busqueda.util;

/**
* Example1.java - call the rfc module 'STFC_CONNECTION' with custom definition
* of function metadata. Please notice, the communication with static
* metadata interface definitions is dangerous. The inconsistencies in the
* interface definitions may cause corrupted data, errors while communication or
* even application crashes. In Example2 you can see, how to avoid these problems.

public class Example1 {

// Create a client connection to a dedicated R/3 system

// Create the input parameter list from the metadata object
JCO.ParameterList input = JCO.createParameterList(input_md);

// Set the first (and only) input parameter

// Create metadata definition of the output parameter list

// Specify the parameters types of the function will be returned
output_md.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255, 255 * (is_backend_unicode? 2 : 1 ),

// Create the output parameter list from the metadata object
JCO.ParameterList output = JCO.createParameterList(output_md);

// Call the function
client.execute("STFC_CONNECTION", input, output);

// Print the result
System.out.println("The function 'STFC_CONNECTION' returned the following parameters:\n" +
"-----------------------------------------------------------------");
for (int i = 0; i < output.getFieldCount(); i++) {
System.out.println("Name: " + output.getName(i) + " Value: " + output.getString(i));
}//for

// All done
System.out.println("\n\nCongratulations! It worked.");
}
catch (Exception ex) {
System.out.println("Caught an exception: \n" + ex);
}
finally {
// do not forget to close the client connection
if (client != null) client.disconnect();
}
}
}


este ejemplo llama a la Fx: 'STFC_CONNECTION' .
