JCO error in storing document in KPRO

Question

Hi Expert,
I have one BAPI to store the document in KPRO. BAPI_DOCUMENT_CREATE2
If call that BAPI in java class program it is working fine.
If i call that java class in web Dynpro application it is not working.
Below code to store the file in to KPRO
public static boolean doUpload(String path,String number){
          JCO.Client client = null,client1 = null;
          JCO.Repository repository = null,repository1 = null;
          JCO.ParameterList inputParameter = null, outputParameter = null,inputParameter1 = null;
          JCO.Function bapiDocument = null,bapiDocument1 = null;
          JCO.Table table_lsdoc=null,table_Doc_Details=null;
          JCO.Table table_in_FilePath=null,table_out_Return=null;
          JCO.Structure st=null,st1=null;
          String file_Path="",return_Message="",doc_Type="",stor_Cat="";
          try{
               client = ConnectToR3.getConnection();
               System.out.println("1");     
               repository = new JCO.Repository("SearchRepository", client);
               System.out.println("2");
               //System.out.println("Connected to repositry");     
               bapiDocument = repository.getFunctionTemplate("Z_DOCUMENT_CREATE").getFunction();
               System.out.println("3");
               JCO.setMiddlewareProperty("jco.middleware.allow_start_of_programs", "ftp;sapftp;sapftpa;sapkprotp;http;saphttp;saphttpa");
               System.out.println("4");
               if (bapiDocument != null){
                    table_in_FilePath=bapiDocument.getTableParameterList().getTable("S_DOCUMENTFILES");
                    table_in_FilePath.appendRow();
                    table_in_FilePath.setValue(number, "DOCUMENTNUMBER");
                    table_in_FilePath.setValue(path, "DOCPATH");
                    client.execute(bapiDocument);
                    System.out.println("5");
                    table_out_Return=bapiDocument.getTableParameterList().getTable("S_DOCUMENTFILES");
                    System.out.println("6");
                    int flag=0;
                    if(table_out_Return.getNumRows()>0){
                         System.out.println("7");
                         table_out_Return.firstRow();
                         for(int i=0;i<table_out_Return.getNumRows();i++){
                              System.out.println("8");
                              System.out.println(table_out_Return.getValue("DELETEVALUE").toString());
                              if(table_out_Return.getValue("DELETEVALUE").toString().equalsIgnoreCase("s")){
                                   flag=1;
                                   break;
                              }else{
                                   flag=0;
                                   break;
                              //table_out_Return.nextRow();
                         if(flag==1)
                              return true;
                         else
                              return false;
                    }else
                         return false;
                    //return false;
               }else
                    return false;
               //return false;
          }catch(Exception e){
               System.out.println("Exception in Upload "+e);
               return false;
          finally{
               try{
                    if (client != null){
                         ConnectToR3.closeConnection(client);          
               catch (Exception ef){
                    System.out.println("Exception in Finally Block in SAPConnect."+ ef.getMessage());
                    return false;
In above code i created Z RFC for some customization. Actual Bapi to Store the file in KPRO "BAPI_DOCUMENT_CREATE2".
To execute this bapi from webdynpro any exe or dll file required.I saw some other thread  2 exe are required to execute the above RFC(<b>SAPFTP.exe, SAPHTTP.exe</b>).
If it is required to place the above 2 exe, where to place that exe's in webdynpro application.
Please help me..  Urgent....

Hi Sunil,
The correct way of running BAPIs from Web Dynpro is using Adaptive RFC.
