Mapping xml for uploading file

Question

hi everyone.
i am in big problem here. for the last couple of days i have been trying to upload a file in my project but cant get through. i am using HTML and servlets to do the upload.....my system is on java 1.4 and tomcap 4.0
at first i did try to use jakarta common upload, but i couldint get the set up correct..... i kept on getting a compile error that the package couldint be found.....so i went for com.oreilly and copied the cos.jar on the common\lib, then took one of the source codes which compiled well.
so i tried to upload a file but failed again, it displayed an error that the directory Tmp not found, so i changed the directory to c:\tmp on the servlet... like this:
MultipartRequest multi =
        //new MultipartRequest(req, "/tmp", 50 *1024 * 1024,
        new MultipartRequest(req, "C:/tmp", 50 *1024 * 1024,
          new com.oreilly.servlet.multipart.DefaultFileRenamePolicy());after changing the dir, this is the new error that i am getting now.
java.io.IOException: Posted content type isn't multipart/form-data
     at com.oreilly.servlet.multipart.MultipartParser.(MultipartParser.java:166)
     at com.oreilly.servlet.MultipartRequest.(MultipartRequest.java:222)
     at com.oreilly.servlet.MultipartRequest.(MultipartRequest.java:151)this is the web.xml i got on my web-inf\web.xml
<?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
- <welcome-file-list>
  <welcome-file>/documentation/index.html</welcome-file>
  </welcome-file-list>
  </web-app>form
out.println("<form method = \"post\" action = \"http://localhost:800/servlet/UploadTest\">");
   out.println("<h3><p align="\" center\"">File Upload</h3><br>");
   out.println("<form action=\"uploadTest\" method=\"post\" enctype=\"multipart/form-data\">");
   //out.println("<td>file Name :</td><td><input type=\"text\" name=\"lname\" size=\"40\"></td></tr>");
   out.println("<table><tbody><tr><td><input type=\"file\" name=\"file1\" /></td></tr><tr><td>");
   out.println("<input type=\"submit\" value=\"Submit\" /><input type=\"reset\" value=\"Reset\" /></td></tr>");
   out.println("</tbody></table></form></body></html>");my questions are:
1). from the com.Orreilly web site, they dont say if i should change the web.XML file.... do i have to edit it to map the oreilly upload package, coz i tried it and i got an error on the tomcat command window
2). do i have to creat the tmp directory manually.
3). is there an easier why to upload files to database.
i would highly appreciate any help, i got 6 days to save my 3 years in uni....please help.
thnx in advance.

hi,
thenx again for your wonderful help.
i am still struggling with the upload part, but i feel i am on the right track. my servlet is compiling well but wen i run it, i am getting an error "*HTTP Status 404 - /servlet/null*".
i am using java 1.4, apache tom cat 4.0 and i did install the jakarta commons fileupload (which i droped commons fileupload.jar and commons io.jar under .../common/lib) and set the path to them as well.
i am using this source code from this web site to do the upload....*http://www.docjar.com/html/api/org/apache/commons/fileupload/FileUploadBase.java.html*
and i am using this servlet with the form to call it.
out.println("<form method = \"post\" action = \"http://localhost:8800/servlet/FileUploadBase\">");
out.println("<h3><p align=\"center\">File Upload</h3><br>");
   out.println("<form action=\"uploadTest\" method=\"post\" enctype=\"multipart/form-data\">");
   //out.println("<td>file Name :</td><td><input type=\"text\" name=\"lname\" size=\"40\"></td></tr>");
   out.println("<table><tbody><tr><td><input type=\"file\" name=\"file1\" /></td></tr><tr><td>");
   out.println("<input type=\"submit\" value=\"Submit\" /><input type=\"reset\" value=\"Reset\" /></td></tr>");
   out.println("</tbody></table></form></body></html>");i feel like my problem is on the web.xml which i am not sure(its located on ....webapps\ROOT\WEB-inf\web.xml). this how it looks like
<servlet>
     <servlet-name>FileUploadBase</servlet-name>
     <servlet-class>fileupload.FileUploadBase</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>FileUploadBase</servlet-name>
     <url-pattern>/classes/FileUploadBase</url-pattern>
</servlet-mapping>general information:
1) the servlets are in .../webapps/root/web-inf/classes
2) i want the uploaded files be stored in a database under c:/ or in a folder c:/tmp
3) commons jar are under common/lib
i will highly appreciate any help you give. thenx
