Two mysteries: ;jsessionid and bad img tag

[Bryce Nesbitt <br...@obviously.com>]

I've just been gifted with a struts application to maintain.
 Things are pretty good, but here are two little mysteries I
need a little help on.  The struts jsp looks like:

<td><html:link page="/"><html:img page="/images/logo.gif"
alt="XX"
width="326" height="111" hspace="0" vspace="0" border="0"
/></html:link></td>

And the resulting HTML is like this:

<td><a href="/;jsessionid=XXXXXXXXXXX"><img
src="/images/logo.gif"
height="111" width="326" border="0" hspace="0" vspace="0"
alt="XX"></a></td>

Why the ";" in the jessionid, instead of &?

And why is there no "/" at the end of the img tag, which is
inconsistent with the rest of the XHTML markup.

These two small issues annoy the Tidy HTML validator in
Firefox, http://users.skynet.be/mgueury/mozilla/

The servlet spec requires that the session identifier be a "path parameter"
rather than a "query parameter".  In the syntax of a URL, you can actually
add path parameters after any element of the path (
http://localhost:8080/foo;bar=baz/bop), but the session id goes on the last
one.

Which version of Struts are you using?  I vaguely recall problems like this
in the very early ones, but not more recently.

It may be that the validator needs to be made to understand what a path
parameter is.

Because this is session ID, not a query parameter. You cannot read it
from Request object as a query parameter or as a mere substring of a
whole URL (this, it is not considered as a part of URL).

Try wrapping your JSP page into <html:html xhtml="true>  tag.
