So...
If you want to transform some XML into some different XML?
"XSLT, which is a language for transforming XML documents into other XML
documents."
http://www.w3.org/TR/xslt
If your 'other namespace' is just a generic placeholder, you could make
it match the namespace of a Tag Library (which you would write to output
what you need).
javax.servlet.jsp.tagext.SimpleTagSupport is quite easy to work with.

Er... huh? You want to modify a JSP on the fly before it gets compiled
and run? Okay...
...
Maybe you could explain what you're really trying to do and we could
suggest an alternative. What you say you're doing is quite... hacky.
Ok, this modification is a small part of my thesis. The reason why the
modification is needed is that I have in the JSP - or maybe in HTML files -
XML tags from an other namespace. These are some placeholders for dynamic
content I need to insert. A simple example would be:
<div>
<xyz:widget param1="<%= var1%>" param2="<%= var2%>"></widget>
</div>
should be converted to
<div>
<ol>
<li><%= var1%></li>
<li><%= var2%></li>
</ol>
</div>
How to transfer the resource to the needed output format is easy to do for
me but like I told a have no clue how to pass the new resource on the fly to
the server that he could render/compile and deliver it to the client. I also
get to know that my approach is a kind of hacky - but it's not for a live
server - only development. So it's not problem when it's hacky or has a bad
performance. :)

Why not just modify it on the disk and use reloadable JSPs?
The reason is that it should be possible to modify not only JSP file but
also HTML or declarative documents at all.

That doesn't sound right. You can apply a filter before a request is
handled (by the JSP servlet) if you want.
Yes your are alright. I explained wrong :) I mean that the document is read
and compiled in one process. I know that it's possible to modify the request
before processing - but I couldn't find a possibility to handle the loaded
resource before compiling.
Thanks for the help,
Martin
