Subject Upgrade to TC6 is breaking the app
Date Sat, 02 Jun 2007 07:31:18 GMT
I am trying to migrate my app from TC5.5.15 to TC6.0.13 under Linux with
JRE1.6.0_01. I basically started with a fresh copy of TC and copied a
virtual host definition to the new version.

All pages use the same JSTL libraries and all work under TC5.5.15. Under
TC6.0.13, All pages under the root of the virtual host are OK; all in
directories below fail when accessed directly. A typical error I get is:


---------------------
Type Exception report

it from fulfilling this request.

And these errors keep alternating back and forth.

Come to think, it was probably a reason why I never moved up the TC5.5.x
branch, since with TC5.5.16 things started breaking and I did not have a
chance to investigate then.

The server log does not help much, since the errors are way too cryptic
for me to decide anything based on them. Example,

--------------

An interesting aspect of this error is, indeed, the fact that
top_favorites.jsp is in an include directory, so not directly in the
root of the site. Yet, it seems that TC6.0.13 is looking for it in the
root when requested directly. When it is included from a page in the
root of the site, however, top_favorites.jsp gets compiled and included
just fine.

What am I missing?


TIA,

Ed
