Error on upload file (User has no access to upload files) [jdev 11.1.1.3]

Question

Hello to all,
I wrote this simple servlet:
import weblogic.management.servlet.MultipartRequest;
public class SaveImage extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
String rtempfile = File.createTempFile("temp","1").getParent();
MultipartRequest mpr = new MultipartRequest(request,rtempfile);
Enumeration files= mpr.getFileNames();
while (files.hasMoreElements()){
String fileName = (String)files.nextElement();
File file = mpr.getFile(fileName);
When I try to upload the image I receive this error:
java.lang.RuntimeException: User has no access to upload files
at weblogic.management.servlet.MultipartRequest.(MultipartRequest.java:169)
at weblogic.management.servlet.MultipartRequest.(MultipartRequest.java:119)
at edu.uniud.ai.servlet.SaveImage.doGet(SaveImage.java:59)
at edu.uniud.ai.servlet.SaveImage.doPost(SaveImage.java:112)
Any idea where I make the mistake?

Answer 1

The column types are correct. I double checked, but also I used the Business Components from Tables wizard to generate the EOs.
I think the problem might be because JDev is set to use UTF8
All of our tables are defined like:
create table junk (col1 varchar2(10 BYTE));
Notice the BYTE in the Varchar2. In all tables, ADF seems to throw the above error on ALL updates.
Any ideas?
