SV: Global DataSource
Hi again. I just solved my problem with global datasources in Tomcat. Instead of putting my and in (which gave me lot's of trouble and exceptions) I put it in the and removed from my web.xml. I don't know if this is a neat solution but hey, it works. :-) /Fredrik -Ursprungligt meddelande----- Från: Fredrik Larsson [mailto:[EMAIL PROTECTED] Skickat: den 11 mars 2003 14:39 Till: [EMAIL PROTECTED] Ämne: Global DataSource Hi all. I'm trying to set up a global DataSource on my Tomcat 4.1.18 standalone to be available to all of my applications installed on the server. But... I just can't get this to work. I've been following the instructions in the tomcat documentation but it doesn't help. I can start the server without any problems and view the global datasource in the Administration Tool but as soon as I'm trying to access the datasource from a servlet i get the following exception: java.sql.SQLException: Cannot load JDBC driver class 'null'. I've tried to set up the datasource for just one application context and that works... but that's not what I want. Another thing is that when I'm trying to view the datasources for one specific application-context that should use this global datasource I get this exception: org.apache.jasper.JasperException: Exception retrieving attribute 'driverClassName' Has anyone got a clue? Thanks! /Fredrik This is what my conf-files look like: SERVER.XML factory org.apache.commons.dbcp.BasicDataSourceFactory maxActive 100 maxIdle 30 maxWait 1 username myusername password driverClassName org.gjt.mm.mysql.Driver url jdbc:mysql://localhost:3306/mydb WEB.XML DB Connection jdbc/MyDB javax.sql.DataSource Container - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I just tried to install the 4.1.21 beta but it didn't help.

I had lots of trouble with JNDI datasources too; it seems there's been done some work on this: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16316 I'd try the 4.1.21 beta to see if it still gives trouble...
