Paul,

         At least one other OpenCMS (OC) user has reported problems when 
using Tomcat (TC) 5.0.19 and the 1.4.2 JDK. He solved the problem by 
upgrading TC. See this email:

1.  From Claus Priisholm, 31 Jan. 2005, "Re: 5.0.1 and Java 1.4.2 - with TC 
4.1."

         On the other hand (OTOH), another user has reported success with 
TC 5.0.19, at least when his TC was linked to Apache using mod_jk (but I 
cannot understand why such linkage would make any difference). See this email:

2.  From Kaffamanesh, 30 Nov. 2004, "HowTo: Apache2-Tomcat5-OpenCMS 
Integrating on SLES9."

         A third user apparently had problems with the combination of JDK 
1.4.2 and TC 5.0.16 and recommended that OC users avoid the 1.4.2 JDK. See 
this email:

3.  From Mariano Barcia, 9 Feb. 2004, "Tomcat 5.0.16 usage."

         What conclusions can we draw from these users' varied experiences? 
Well, these experiences suggest that, if you are  having problems with an 
OC installation, sometimes you can solve your problems simply by changing 
your version of TC or the JDK. None of the users above indicated which JDK 
they were using, so it was probably Sun's JDK, rather than that of another 
JDK maker (e.g., IBM). BTW, you can still download the 1.4.1 JDK from Sun's 
website.

         It would not hurt to restart TC -- perhaps that will solve your 
problem.

         Finally, if you need more help, please remember that, when 
requesting help, you should supply the information below. You are more 
likely to get help if we do not have to prod you for information.

A. The most recent contents of these log files:

         1. opencms.log
         2. catalina.out -- if you are using Tomcat
         3. The MySQL log file -- on Debian Linux, it is <hostname>.log

B. Your environment and configuration:

-- OpenCMS (OC) version number, for example (e.g.), ver. 5 or ver. 6.
-- Servlet container and its version number, e.g., Tomcat (ver. 4 or 5.x), 
Jetty, or Resin.
-- RDBMS and its version number, e.g., MySQL (ver 3.2x or 4.x), Oracle, or 
MS SQL Server.
-- JDK, including both: (a) compiler and its version (e.g., Sun, Blackdown, 
IBM's Jikes, or GCJ), and (b) JVM and its version, e.g., Kaffe.
-- Operating system and its version, and, if using Linux, the distribution 
and its version number, too. For example:

                 -- Red Hat Enterprise Linux, ver. 3
                 -- SuSe Linux, ver. 9
                 -- Debian Woody or Debian Sarge ("Testing")

-- If you are using Linux, state whether you installed the software 
packages above using a package management system (e.g., RPM, dpkg, Stow, 
emerge, or "Apt for RPM") or manually instead.
-- The version of the JDBC driver is probably not necessary unless you have 
replaced the JDBC driver that the OC setup wizard installs during the OC 
installation.

Sincerely,
Paul Bain
