I'm new to ofbiz so try to keep your answer as simple as possibly. If you can give examples that would be kind.

My problem is I created a project inside the ofbiz/hot-deploy folder namely productionmgntSystem. Inside the folder ofbiz\hot-deploy\productionmgntSystem\webapp\productionmgntSystem I created a file app_details_1.ftl.

The following are the code of this file

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
        <title>Insert title here</title>
        <script TYPE="TEXT/JAVASCRIPT" language=""JAVASCRIPT">
            function uploadFile()
            {
                //alert("Before calling upload.jsp");
                window.location='<@ofbizUrl>testing_service1</@ofbizUrl>'
            }
        </script>
    </head>
        <!-- <form action="<@ofbizUrl>testing_service1</@ofbizUrl>" enctype="multipart/form-data" name="app_details_frm"> -->
        <form action="<@ofbizUrl>logout1</@ofbizUrl>" enctype="multipart/form-data" name="app_details_frm"> 
        <center style="height: 299px; ">
            <table border="0" style="height: 177px; width: 788px">
                <tr style="height: 115px; ">
                    <td style="width: 103px; ">
                    <td style="width: 413px; "><h1>APPLICATION DETAILS</h1>
                    <td style="width: 55px; ">
                </tr>
                <tr>
                    <td style="width: 125px; ">Application name : </td>
                    <td>
                        <input name="app_name_txt" id="txt_1" value=" " />
                    </td>
                </tr>
                <tr>
                    <td style="width: 125px; ">Excell sheet &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;: </td>
                    <td>
                        <input type="file" name="filename"/>
                    </td>
                </tr>
                <tr>
                    <td>
                       <!-- <input type="button" name="logout1_cmd" value="Logout" onclick="logout1()"/> -->
                       <input type="submit" name="logout_cmd" value="logout"/>
                    </td>
                    <td>
                        <!-- <input type="submit" name="upload_cmd" value="Submit" /> -->
                        <input type="button" name="upload1_cmd" value="Upload" onclick="uploadFile()"/>
                    </td>                   
                </tr>
            </table>
        </center>
    </form>
</html>

the following coding is present in the file ofbiz\hot-deploy\productionmgntSystem\webapp\productionmgntSystem\WEB-INF\controller.xml

The following are the coding present in the file ofbiz\hot-deploy\productionmgntSystem\src\org\ofbiz\productionmgntSystem\web_app_req\WebServices1.java

                DataInputStream in = new DataInputStream(request.getInputStream());
                int formDataLength = request.getContentLength();
                byte dataBytes[] = new byte[formDataLength];

                saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
                saveFile = saveFile.substring(saveFile.lastIndexOf("\\")+ 1,saveFile.indexOf("\""));
                int lastIndex = contentType.lastIndexOf("=");
                String boundary = contentType.substring(lastIndex + 1,contentType.length());
                int pos;

                //extracting the index of file

            }
            catch(IOException ioe)

                //ioe.printStackTrace();
                return("exception");
            }
            catch(Exception ex)
            {
                System.out.println("\n\n\t*********************************\n\tInside WebServices1.testingService(HttpServletRequest request, HttpServletResponse response) - Catch Exception");
                return("exception");
            }
        }
        else
        {
            System.out.println("\n\n\t********************************\n\tInside WebServices1.testingService(HttpServletRequest request, HttpServletResponse response) else part");
            result="exception";

        return(result);
    }
}

I want to upload a file to the server. The file is get from user " tag in the "app_details_1.ftl" file & it is updated into the server by using the method "testingService(HttpServletRequest request, HttpServletResponse response)" in the class "WebServices1". But the file is not uploaded. Give me a good solution for uploading a file to the server.
