relative action paths

[admin]

Hello,

I am a new developer who is hoping someone here on this list
can help me figure out this problem we are having:
I need to be able to use relative paths so as to keep my URL
(which varies quite a bit across our app)
so instead of this:

<html:form  action="/contactByEmail" focus="name">

i want to be able to do this:

<html:form  action="contactByEmail" focus="name">

I found what looks to be a solution to this in the
issues.apache.org/bugzilla  site, #17449 but I'm
not too sure how to integrate that patch/changes
into my application.
If anyone can offer some help or suggestions, it would
be much appreciated!
Thanks,
Devin
