Hi,
u can use jco connection for the same which u can download from  http://service.sap.com/connectors.
1.Download the zip file and unpack it into any directory.
2.Copy the file librfc32.dll into the directory C:\WINNT\system32.
3.Add sapjco.jar to the classpath of the
Java project.
4.Required import statement:
import com.sap.mw.jco.*;
Then make two classes and write code as mentioned in example below:
public class JCoTest {
  public static void main(String[] args) {
    if (JCoSpfliGetDetail
      .connectToSAP("xxx", "xxxxxxx", "xxxxxxx", "xx", 
            "xxxx", "xx")) {
      JCoSpfliGetDetail.showConnectionDetails("LH", "400");
      JCoSpfliGetDetail.disconnectFromSAP();
public class JCoSpfliGetDetail {
  private static JCO.Client mConnection = null;
  private static JCO.Function function = null;
  private static JCO.Repository mRepository = null;
  //Connect to SAP
  public static boolean connectToSAP(
    String client,
    String user,
    String passwd,
    String lang,
    String appServer,
    String sysNo) {
    try {
      mConnection = JCO.createClient(
            client, //SAP client
            user, //userid
            passwd, //password
            lang, //language
            appServer, //app server host name
            sysNo); //system number
      mConnection.connect();
      mRepository = 
        new JCO.Repository("JA100", mConnection);
} catch (Exception e) {
e.printStackTrace();
      return false;
    return true;
//Call Remote Function Module
  public static void showConnectionDetails(String carrid, 
                 String connid) {
    function = 
      JCoSpfliGetDetail.createFunction("SPFLI_GETDETAIL");
    if (function == null)
      throw new RuntimeException(
          "Remote Function Module not found");
    //Supply the import parameters of the RFM
    JCO.ParameterList im_param = 
          function.getImportParameterList();
    im_param.setValue(carrid, "CARRID");
    im_param.setValue(connid, "CONNID");
    mConnection.execute(function);
//Disconnect from SAP
  public static void disconnectFromSAP() {
    mConnection.disconnect();
//Create instances of class JCO.Function
  private static JCO.Function createFunction(String name) {
    IFunctionTemplate ft =
      mRepository.getFunctionTemplate(name.toUpperCase());
    if (ft == null)
      return null;
    return ft.getFunction();
