JSP form sending data including files in servlet

I am tryig to send some data from jsp form to a servlet. All my data are type="text" except from one that is type="file". I know that if i want to send the data to my servlet, i have to use request.getParameter(...). (My data) In order not to be null i have to use method="get". But if i want to upload a file i have to use method="post". How can i pass both types to my servlet using one form? Thanks in advance!


<form method="post" action="Servlet"> user:<input type="text" name="user"/> img<input type="file" name="img"/> </form>


doPost(req,resp){ user = req.getParameter("user");//user == NULL }



<form method="get" action="Servlet"> user:<input type="text"/> img<input type="file"/> </form>


doGet(req,resp){ //img not passed }

-------------Problems Reply------------


<form id="uploadForm" name="uploadForm" action="UploadServlet" method="post" enctype="multipart/form-data">
user:<input type="text" name="user"/>
img<input type="file" name="image"/>

You can still get both with a post request:

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
InputStream fileContent = null;
String user = "";
for (FileItem item : items)
if (item.isFormField())
String fieldName = item.getFieldName();
String fieldValue = item.getString();
user = fieldValue;
String fieldName = item.getFieldName();
fileContent = item.getInputStream();

This is just an example of how to handle post request with file type.
