problems with XSLT and Tomcat Realms

[Edu]

Hi all,

I had working a servlet that transformed xml data into wml or html
(depending on the client browser). Everything was OK, but today I tried to
add authentication before using the servlet.

I use authentication with tomcat realms and (from web.xml)
<auth-method>FORM</auth-method>.

Now, once authenticated, the servlet doesn't work ant throws:

org.xml.sax.SAXParseException: Character conversion error: "Malformed UTF-8
char
-- is an XML encoding declaration missing?" (line number may be too low).

If I deactivate authentication, things return to work fine.


How can I solve the problem?


Thank you in advance

I've found the problem (but still not the solution)!!

The problem is that from my servlet (the XSLT transformer), I request
another servlet (returns XML) which also requires authentication, so the
servlet transformer can't get the XML data and the exception is thrown when
the transformer receives the login page from the xml provider.

Now, is there a way to perform the authentication between the servlets?



Thanks again.

Well, AFAIR in Java such problems are usually solved using custom URIResolver,
which takes over document() function execution and implements additional
authentication job in there.
