I am using the commons-fileUpload 1.1.1 lib to upload files to my
server. The objective is to insert some info in a DB together with the
file path in the server.

The problem is that when I put the ENCTYPE to multipart/form-data, the
other parameters are set to NULL in the servlet that treats the
request.

Did anyone run into this problem?

<FORM ENCTYPE="multipart/form-data" method="post" ACTION="<%=
UtilityClass.APP_PATH + "servlet/ServletDebtLetter" %>" >
<input type="file" name="fileName" maxlength="100" size="30"/>
<input type="text" name="subject" maxlength="100" size="30"/>
</form>

In my doPost method on my servlet I have this in the first line:

public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
System.out.println(request.getParameter("subject"));
...
}

The output of the println is NULL. Anyone has any clue about it???

Some code snippets:

<form action="xuploaddo.jsp" enctype="multipart/form-data" method="post">
Beskrivelse: <input type="text" name="beskrivelse"/><br/>
Fil: <input type="file" name="fil"/><br/>
<input type="submit" value="Submit"/>
</form>

<%@page import="org.apache.commons.fileupload.*,java.util.*,java.io.*"%>
<%
DiskFileUpload upload = new DiskFileUpload();
List files = upload.parseRequest(request);
for(int i = 0; i < files.size(); i++) {
    FileItem file = (FileItem)files.get(i);
    if(file.getFieldName().equals("beskrivelse")) {
       String beskrivelse = file.getString();
       out.println("beskrivelse=" + beskrivelse);
    }
    if(file.getFieldName().equals("fil")) {
       String filename = "C:\\test.upl";
       file.write(new File(filename));
    }
}
%>

PS: The word "beskrivelse" in danish is "description" in english.
