Configuring the manager application for Tomcat 6

[Peter Stavrinides <p....@albourne.com>]

Hi all,

This may be a trivial problem for most, but here goes... I am upgrading 
my Tomcat 5 server to Tomcat 6, which has gone pretty smoothly except 
for one problem with the manager application.

A copy of the manager application is running on my server instance, I am 
also using a JDBC realm with basic authentication to authenticate for 
the manager application. The caveat is that I require the postgres 
driver on my classpath, so I placed it in $CATALINA_BASE/lib but the 
manager app  still can't authenticate and I get JDBC related errors in 
the logs (it can't find the driver?), but when I place the driver in 
$CATALINA_HOME/lib instead everything works.

Ideally I don't want to mix proprietary libraries with the Tomcat 
libraries in $CATALINA_HOME/lib, I would like to leave the default 
binaries alone to simplify upgrades, everything should be run in my 
instance. So I need to find out how to configure the manager application 
to look in the correct place for the driver. I realize that there have 
been major changes to the classloader, and I have also seen the 
documentation for configuring <GlobalNamingResources> and realize this 
might be what I need, is it? If so how do I configure a <Resource> for 
my JDBC realm and driver. Why is it that placing the library in 
$CATALINA_HOME/lib just works? and the manager app knows how to find it 
there.

Thanks a lot for your help,
Peter

Thanks for the heads up. Trunk has been fixed. Patch proposed for 6.0.x

The documentation in RUNNING.txt is incorrect for Tomcat 6.  In
particular, there is no $CATALINA_BASE/lib, as you can tell by looking
in the conf/catalina.properties file.  The common.loader is defined to
use ${catalina.home}/lib.

You might want to enable the shared.loader in conf/catalina.properties,
targeting ${catalina.base}/lib, and put your JDBC driver there.

Note that RUNNING.txt claims that *every* Tomcat directory can be under
$CATALINA_BASE, which, of course, makes no sense, since that would leave
nothing under $CATALINA_HOME.  Looks like this file wasn't updated for
the revised directory structure.
