JSP sendRedirect broken from JSP welcome-file in subdir?

[pichler.mi]

Hello,

I just tried jboss 3.0.2 with jetty 1.4.

Our webapp defines a welcome-file in a subdirectory, e.g.
subdir/Welcome.jsp which should redirect to a relative location. When
running it in tomcat or jetty standalone it works (it also worked with
jboss 3.0.0 with tomcat), but with the combination above, the redirect
URI is interpreted relative to the server root (even outside the
application context), not the location of the jsp file.

The difference (bug?) can also be observed with request.getRequestURL().

A simplified version of the webapp is attacht as welcome.war. Any
clues what's wrong? PS: We have found jboss a great product besides
this minor glitch.

I'm pretty sure that such welcome files are not legal and
your lucky that they work at all!

I would suggest that you keep the welcome files in the
current directory.

You can always create an index in the parent directory
that contains a meta redirect to the subdirectory.

If I was to make a change for this, it would be to
throw an exception is we saw such a welcome file. Sorry.

I'm going to ask JSR154 if they can clarify this in the 2.4 spec.

[gregwilkins]

Correcting myself a little....

a welcome file like you have /subdir/index.html
is not legal, but subdir/index.html is.

The spec says that a welcome file partial URI should
not contain a leading or trailing "/"

It didn't work with subdir/Welcome.jsp either, but, OK, a welcome-file that redirects into another directory is probably a bad idea anyways.

Thus I have changed the welcome-file to plain Hello.jsp located in the root dir of the webapp (hello.war) which does
<% response.sendRedirect ("subdir/target.html"); %>

That seems legal to me and works for Jetty alone, but not with JBoss 3.0.2 when just requesting "/hello/" (or "/hello" whicht gets redirected to "/hello/"); Also notice the different value of request.getRequestURL() which is taken as base for the redirect.

BTW, the redirect works as expected when accessing "/hello/Hello.jsp" explicitly. The problem is only with a JSP welcome file performing a redirect.

It works well with jboss 3.0.3 (bug 611044 closed)
for both the hello example and our application with a
welcome-file in a subdirectory (without leading /).

Thanks.
