FileUpload

[Peter Lauri]

Best groupmember,

I have downloaded the CommonFileupload and have problems the thrown errors.
I have put the jar in $catalina_home/shared/lib and in the
$catalina_hom/webapps/myproject/WEB-INF/lib. I have never had problem with
creating servlets, no problems before.

I started out just by the tutorial about using FileUpload at
http://jakarta.apache.org/commons/fileupload/using.html . The first part is
to check if we have a fileupload request (I am certain I have). The code is:

public void doPost (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
     PrintWriter out = response.getWriter();
     if(FileUpload.isMultipartContent(request)) {
          out.println("Ok, there is a multipart content...");
     } else {
          out.println("No multipart content...");
     }
}

This is the basic part, and it throws an error. I have tried other functions
to and they throw similar errors. People suggest to but the servlet-api.jar
in the CLASS_PATH, but I have it already there since long time. 

Here is the error I get, anyone with experience of the same thing?:

exception 

javax.servlet.ServletException: Invoker service() exception
org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java
:477)
org.apache.catalina.servlets.InvokerServlet.doPost(InvokerServlet.java:169)
javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

root cause
