Xerces 2.2.x & Struts 1.0.2 problem.

[Jeanfrancois Arcand <jf...@apache.org>]

Hi,

finally, with the help of Craig, I was able to isolate the problem 
Tomcat have with Xerces 2.2.x. When you have  an <!ELEMENT line longer 
that 80 characters in a DTD, Xerces 2.2.x thrown the misleading 
exception everybody have seen.

In our case, file web-app_2_3.dtd included with Struts 1.0.2 is causing 
the problem (Strangely, this is not the same as the web-app_2_3.dtd 
included in jakarta-servletapi). Struts 1.1 have a 80 characters format.

We have 3 solutions:

(1) Bundles Struts 1.1 latest build with Tomcat 4.1.x
(2) Compile Struts 1.0.2 with our version of web-app_2_3.xml and commit 
the jar file in the webapp WEB-INF/lib folder.
(3) Wait for a new release of Xerces (or when the fix will be available).

The bugzilla bug: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13282

This bug was difficult to isolate :-)

Great ! (Craig saves the day again :) )

Ok, the following is just IMO.

I would rather not.

I don't like it either.

I would choose that one.

I haven't updated my set of binaries at all to build 4.1.15 (the 
rationale is: why upgrade when everything works fine ?). I plan to do 
some conservative upgrading for the next build, including:
- Xerces 2.2.2 (if out by then)
- MX4J 1.1.1
- Beanutils 1.5
- Collections 2.1

I suppose. The reported error was Microsoftian ;-)

The pragmatic way should be to ask for a struts 1.0.2a release including 
the correct web-app_2_3.xml ;)
