Subject Re: DataSource from Context files - doesn't work
Date Wed, 01 Apr 2009 10:17:14 GMT
I have the following files in the logs directory:

admin.2009-04-01.log
catalina.out
localhost.2009-04-01.log
catalina.2009-04-01.log
host-manager.2009-04-01.log
manager.2009-04-01.log

Which one of them should I VI or LESS to find the complete stack trace for
the exception?

Also, is there something obviously wrong with my context definition or
reference? I followed the Tomcat online tutorial to define them.
Also, previously a regular JDBC code with the same parameters was able to
access the DB and retrieve the data correctly.

Thank you all.
