Hi,

We are developing example application "JSF File Upload". Hopefully it will be done by tomorrow.

Any idea how to upload files using jsf?

You can read File upload in struts in our struts section.

Do you need this application in struts? or jsp application will also work?

Thanks

hi...
sorry for late reply...i am writing a program for uploading files...that i got.but in the form one textbox values and memu list is included for company name and category level..if i am writing the company name in textbox and category level as level1,level2 etc.then this values is also automatically writing into that uploading file...when the encryption type is set as multipart/form data then the textbox value is not taken..otherwise no uploading is worked..but the text value is null..here is my code

<%@ page import="java.beans.*"%>
<%@ page import="java.lang.*"%>
<%@ page import="java.io.*,javax.servlet.http.HttpServletRequest,javax.servlet.ServletInputStream"%>
<%@ page import="java.io.FileWriter,java.io.IOException "%>

byte dataBytes[] = new byte[formDataLength];
int byteRead =0;

while (totalBytesRead < formDataLength)
{
byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
totalBytesRead += byteRead;
}
String file = new String(dataBytes);
String saveFile = file.substring(file.indexOf("filename=\"") + 10);
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
//out.print("FileName:" + saveFile.toString());
saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
//out.print("FileName:" + saveFile.toString());

//out.print(dataBytes);

int lastIndex = contentType.lastIndexOf("=");
String boundary = contentType.substring(lastIndex + 1,contentType.length());

Hi,

Can you explain me what do you want to do in detail? Write the program flow, we will develop the example code for you.

Thanks
