RE: Handling POST in VelocityServlet (RESOLVED)
Hello all,
So the problem is that the form specifies encoding
type:
<form method="post" action="http://127.0.0.1:8181"
enctype="multipart/form-data">
If I remove the encoding:
<form method="post" action="http://127.0.0.1:8181">
then the code previously submitted works.
This is a problem since without specifying the
encoding I cannot use Jakarta Commons FileUpload
(http://jakarta.apache.org/commons/fileupload/) to
process uploads so I need to patch one or the other to
move forward.
Regards,
Ivo

A bit more detail.
If you look in the Java Servlet Specification, under "SRV.4.1.1 When
Parameters Are Available", you will see:
<excerpt>
The following are the conditions that must be met before post form data
will be populated to the parameter set:
1. The request is an HTTP or HTTPS request.
2. The HTTP method is POST.
3. The content type is application/x-www-form-urlencoded.
4. The servlet has made an initial call of any of the getParameter
family of methods on the request object.
</excerpt>
Item #3 says, that if you set any other enctype, they will not be
available via the getParameter methods.
So this is not a bug at all, but a good sign that Jetty is following the
specs.

Yes, it looks more like a servlet issue. Check here for other solutions:

Hi, I don't think this is a Velocity bug. In your doPost methdd, you
need to check
FileUpload.isMultipartContent(request). If it's true, you need to use
DiskFileUpload.parseRequest to get the form parameters and file name
etc. If not, you can use request.getParameters. This is documented in
FileUpload usage.
