Help! multipart/form-data use GET, not POST

In a routine common HTML form:

<FORM ACTION="/servlet/BlahBlah" ENCTYPE="multipart/form-data">

input data are sent via GET, not POST. That is very incovenient because
of URL encoding. However, if we explicitly specify the POST method,

<FORM ACTION="/servlet/BlahBlah" METHOD="POST" ENCTYPE="multipart/form-data">

data are not sent from the client and every response.getParameter() is null.

I'd like to hear what do you guess/suspect could be the cause of this
malfunctioning?

I'm using Resin 2.1.12.

Thanks in advane,
