Urgently needed help in BAPI

Question

hello everybody,
I have a BAPI called "CreateFromData" for business object called 'SalesOrder'.
i want to use this BAPI in Java(developer studio).
we can use this method to create sales orders.
A sales order contains information about prices, quantities and dates.
A sales order consists of several items that contain the quantity of the material or service specified for the order.
we have to enter item data required for  using the above BAPI using ORDER_ITEMS_IN table(this is a parameter for the above mentioned method).
how to enter data into this parameter(table) from java...i know that we have to use Jco but how to use it i donot know....i mean how to give parameter values to these methods in java?
pls help me reagarding this problem...
thx in advance,
bye,
aj.

Hi Ajay,
Yake this code to call your BAPI from your JAVA class.
This is the sample program for BAPI "BAPI_SALESORDER_GETLIST"
import com.sap.mw.jco.*;
public class Example2 {
  // The MySAP.com system we gonna be using
  static final String SID = "R3";
  // The repository we will be using
  IRepository repository;
  public Example2()
    try {
      // Add a connection pool to the specified system
      //    The pool will be saved in the pool list to be used
      //    from other threads by JCO.getClient(SID).
      //    The pool must be explicitely removed by JCO.removeClientPool(SID)
      JCO.addClientPool( SID,         // Alias for this pool
                         10,          // Max. number of connections
                         "000",       // SAP client
                         "johndoe",   // userid
                         "*****",     // password
                         "EN",        // language
                         "appserver", // host name
                         "00" );
      // Create a new repository
      //    The repository caches the function and structure definitions
      //    to be used for all calls to the system SID. The creation of
      //    redundant instances cause performance and memory waste.
      repository = JCO.createRepository("MYRepository", SID);
    catch (JCO.Exception ex) {
      System.out.println("Caught an exception: \n" + ex);
  // Retrieves and prints information about the remote system
  public void systemInfo()
    try {
      // Get a function template from the repository
      IFunctionTemplate ftemplate = repository.getFunctionTemplate("RFC_SYSTEM_INFO");
      // if the function definition was found in backend system
      if(ftemplate != null) {
        // Create a function from the template
        JCO.Function function = ftemplate.getFunction();
        // Get a client from the pool
        JCO.Client client = JCO.getClient(SID);
        // We can call 'RFC_SYSTEM_INFO' directly since it does not need any input parameters
        client.execute(function);
        // The export parameter 'RFCSI_EXPORT' contains a structure of type 'RFCSI'
        JCO.Structure s = function.getExportParameterList().getStructure("RFCSI_EXPORT");
        // Use enumeration to loop over all fields of the structure
        System.out.println("System info for " + SID + ":\n" +
        for (JCO.FieldIterator e = s.fields(); e.hasMoreElements(); ) {
          JCO.Field field = e.nextField();
          System.out.println(field.getName() + ":\t" + field.getString());
        }//for
        System.out.println("\n\n");
        // Release the client into the pool
        JCO.releaseClient(client);
      else {
         System.out.println("Function RFC_SYSTEM_INFO not found in backend system.");
     catch (Exception ex) {
       System.out.println("Caught an exception: \n" + ex);
  // Retrieves and displays a sales order list
  public void salesOrders()
     JCO.Client client = null;
    try {
      // Get a function template from the repository
      IFunctionTemplate ftemplate = repository.getFunctionTemplate("BAPI_SALESORDER_GETLIST");
      // if the function definition was found in backend system
      if(ftemplate != null) {
          // Create a function from the template
          JCO.Function function = ftemplate.getFunction();
          // Get a client from the pool
          client = JCO.getClient(SID);
          // Fill in input parameters
          JCO.ParameterList input = function.getImportParameterList();
          input.setValue("0000001200", "CUSTOMER_NUMBER"   );
          input.setValue(      "1000", "SALES_ORGANIZATION");
          input.setValue(         "0", "TRANSACTION_GROUP" );
          // Call the remote system
          client.execute(function);
          // Print return message
          JCO.Structure ret = function.getExportParameterList().getStructure("RETURN");
          System.out.println("BAPI_SALES_ORDER_GETLIST RETURN: " + ret.getString("MESSAGE"));
          // Get table containing the orders
          JCO.Table sales_orders = function.getTableParameterList().getTable("SALES_ORDERS");
          // Print results
          if (sales_orders.getNumRows() > 0) {
            // Loop over all rows
            do {
              System.out.println("----
              // Loop over all columns in the current row
              for (JCO.FieldIterator e = sales_orders.fields(); e.hasMoreElements(); ) {
                 JCO.Field field = e.nextField();
                 System.out.println(field.getName() + ":\t" + field.getString());
              }//for
            } while(sales_orders.nextRow());
          else {
