Hi Gary,
This behaviour is not common to all servlet-engines (or browsers).
Perhaps you don't get the wanted results because query-string parameters
should be sent via "GET" method, not through "POST" wich is used as default
for ... posting HTML forms.
A form's "ACTION=" string with an "?" in it might be confusing for both
browsers and servlet engines.
You may try (without warranties, results depend on browser or servlet engine
used, worst case when you combine large form data with MSIE)
to send all FORM's parameters using GET:
<FORM ACTION="/servlet/projects?name=joe" METHOD=GET>
.... other fields
</FORM>
The *safest* way is to use hidden fields:
--------------------------------
<FORM ACTION="/servlet/projects">
<INPUT TYPE=HIDDEN NAME=name VALUE=joe>
... other fields
</FORM>
----------------------------------
