Subject Re: Jaybird With Tomcat Part II
Date Wed, 28 May 2003 22:17:24 GMT
Of course, and I wouldn't be asking the question without tons of 
research on my own. I will post the errors below for what I was 
receiving previously, yet now when  I copy the libs into common/lib, the 
webapps are inaccessible.

Here is my previous email:

Hey guys, I am hoping I could get some help with this issue. The 
research I have done online reveals this error with several databases 
although I have yet to find a actionable answer nor anything firebird 
specific. I am attempting to connect Firebird to Tomcat based on the 
MYSQL example in the Tomcat Docs and through the datasource setup in the 
administration console. I have attempted to include all relevant data to 
show the activity on my server,  including the log, the example code, 
and the relevant server.xml code.

I appreciate all help that you can offer.
Rob
