Re: Jaybird With Tomcat Part II
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.

Jaybird With Tomcat Part II
Just to clarify: I am using Windows 2000 Pro Tomcat 4.1.18 Firebird Version 1 FirebirdSQL-1.0.0 (Jaybird) I just want Tomcat to connect to a Firebird database on a windows 2k system using the Jaybird Type 4 driver from Firebird. Simple as that. Just a .jsp to test it and the Tomcat configurations. I have been work deligently on this for about a week now - could someone offer some insight? As indicated in my previous post, I have followed all documentation (what there is), search for answers on the firebird site, google, and submitted a paid question to google answers. Any help would be greatly appreciated. -- Thanks, Robert Casteen TEST ADVANTAGE, Inc.

Jaybird With Tomcat?
Has anyone got this to work? I have gone over all the Tomcat/Firebird documents and have yet to find a comprensive guide for this setup. When I copy the libs over to common/lib, Tomcat stops running. Could someone please shine some light onto this for me. I am desperate. I have searched google, offered to pay for the answer in google answers, posted to firebird groups and here a few times. If someone has got this to work, please explain in detail how. Your help is greatly appreciated. -- Thanks, Robert Casteen TEST ADVANTAGE, Inc.

Re: Firebird|Tomcat "java.sql.SQLException: Cannot load JDBC driver class 'null'"
Thank you Chong for your reply, Perhaps I need to clarify, I have downloaded the FirebirdSQL-1.0.0 (Jaybird) driver and am following the directions in the FAQ file, with modifications to the connection url for the fact that I am on a windows system. As far as the type 4 driver that is included (that you mentioned), I do not see any info other than release notes (which seem to indicate the driver I downloaded and installed are same as the one included) the information in the release are very general in nature and not help in the way of installation and testing. The Jaybird driver is the one I wish to use due to the connection pooling feature, I am following the information in the Tomcat "jndi-datasource" howto in the Tomcat docs, although as indicated in my previous email, I am having little luck. In addition, I want to confirm that I have placed all relevant .jars in the commom/lib directory. Again thank you for your previous response - any additional assistance will be very helpful. Thank you, Rob Chong Yu Meng wrote: Hello Rob ! I'm not sure if you are aware : the Firebird database comes with 2 JDBC "flavors", a Type 4 JDBC driver (which is a separate download) and Interclient (which is really more of a JDBC mediation component). The configuration for Interclient is covered in this link : http://www.kpi.com.au/interbase/index.jsp while the configuration for the Type 4 JDBC driver is in the README file that comes with the driver download. Depending on which driver you use, the configuration is *very* different! If you are following the MySQL examples, you should use the Type 4 driver. Second, make sure that your JDBC driver is in your CLASSPATH and that Tomcat can "see" it. That is, either point to it explicitly in your CLASSPATH, or save the jar file into $TOMCAT_HOME/common/lib.
