Kyle, I'm glad to hear the problem is resolved. To your question on Struts v1.2.X and DataSources, the release notes http://struts.apache.org/userGuide/release-notes.html describe the changes as:
- GenericDataSource / GenericConnection implementations removed - The datasources manager is still supported, but our own datasource implementation is not. You are welcome to plug in your own DataSource implementation, but we do not have the resources to maintain one of our own. If your container does not supply a DataSource implementation, the DBCP package from the Jakarta Commons is suggested. - I'm afraid I can't help you with Vic's suggestion about setting up a Tomcat pooled connection. I tried that when I first started using Hibernate as my O/R software and I couldn't make it work. Then again, I was also very new to Java, Hibernate, Struts, and Tomcat. I do remember reading that depending on where you specify the database connection pool in your Tomcat configuration file, the resulting JNDI object could be accessible not just to your webapp but to other webapps as well. That potentially allows you to develop many webapps while using one shared set of connections to a database. I might need that someday so if you figure it out, please wiki it or post it for all to learn. :) And don't forget to use a stable production JAR whenever possible: no long-term use of b1, b2, rc1, rc2.. releases. ;) Regards, David P.S. Thanks again for the clutter-reducing Eclipse trick "User Library". :) -----Original Message----- From: Kyle Korndoerfer [mailto:[EMAIL PROTECTED] Sent: Saturday, October 02, 2004 2:01 PM To: Struts Users Mailing List Subject: RE: Problem with PostgreSQL data source David, Thanks for the quick response... > On Tuesday you wrote that you were going to download the latest > drivers from http://jdbc.postgresql.org/download.html.

No, using newer drivers did not help matters any. I had the exact same error message(s) as before and I must have missed Paul's note note on the mailing list. I had kinda the same feeling about the 'b1' in the name which caused me to think that maybe the JAR file was the problem (even though the classes were all there). > Just to confirm, when you use pgAdmin III, are you using the exact > same username and password as your JDBC setup?

No. I had created a user account specifically for the web application with specific permissions. I thought I was using this account with pgAdmin, but it turns out I wasn't. When I attempted to make a new connection using this username & password, I got an error and realized that I had changed the username (to something more logical) in the database a while back and had forgotten to update the Data Source configuration! Doh! The error message from Struts wasn't all that helpful. It led me to think that my WAR file wasn't correct (but I double-checked it) and/or Tomcat's classpath wasn't correct. Since I was putting the PostgreSQL JAR file into my WEB-INF/lib directory, this shouldn't have been that case. > You also mentioned you are using your PostgreSQL jar as a user > library in Eclipse.

I ask because you > mention your added it to your User Library but a User Library doesn't > require the JAR to be in your webapp /WEB-INF/lib or even in a Tomcat > directory. I only mentioned that I had the PostgreSQL JAR setup as a User Libray in Eclipse and added as a libray to the project to show that all of the classes were being found correctly (so I had a 'complete', and hopefully functional, JAR file). My ant script copies the PostgreSQL JAR file into the WAR file as part of the WAR task (using the 'lib' subtask). I had verifired this several times just to make sure. > And you are still on Struts v1.1 which has the old DataSource > support, not 1.2 which I don't think has that anymore, right? At this point, I am still using Struts v1.1, as that is the only version I have any experience using, so I don't know if the DataSource element is still legal under v1.2.x. If you know of a good resource that shows me what the differnces are for v1.2.x, I like to take a look at it to see if it's worth upgrading to. > Until you pointed it out (thanks, it helps reduce display clutter), I > hadn't tried user libraries in Eclipse before.

Yeah, I found out that little gem when I was reading the release notes for one of the milestone builds. Very nice addition since you don't have to have 10+ JAR files all showing up. You can group them into a logical group, like 'Struts v1.1', and have that show up. Again, I only use Sysdeo as an easy means of launching Tomcat from within Eclipse and having the debugger automatically attached to it. I don't use any of the Wizards that come with it. Now that the problem has been resolved, Vic mentioned that this isn't the best approach to be using. He recommended that I always use the container to manage the Data Source Pooling, in particular: "... rather the DataSourcePool that comes with JDBC drivers. Connections are more for clients and PooledDataSource is for servers, so use that part of any JDBC driver." Everything that I've some across uses the 'org.apache.commons.dbcp.BasicDataSource' or 'org.apache.commons.dbcp.BasicDataSourceFactory' in Tomcat, or building the connection manually in code (not configured in an App Server). How would I use Vic's suggesstion and use the pooled connection source from the PostgreSQL JDBC drivers? Thanks for the help giving my brain a good kicking... ;) -={ Kyle }=- > -----Original Message----- > From: Kyle Korndoerfer [mailto:[EMAIL PROTECTED] > Sent: Saturday, October 02, 2004 11:20 AM > To: Struts Users Mailing List > Subject: Re: Problem with PostgreSQL data source > > > > 1.
