For some reason, our jdbc connection is no longer coming back up, and I have no idea why. I get the following in catalina.out:

Starting service Tomcat-Standalone Apache Tomcat/4.0.3 ConnectionPool: JDBCDriver = org.gjt.mm.mysql.Driver ConnectionPool: JDBCConnectionURL = "jdbc:mysql://localhost/arc" ConnectionPool: ConnectionPoolSize = 5 ConnectionPool: ConnectionPoolMax = 100 ConnectionPool: ConnectionUseCount = 5 ConnectionPool: ConnectionTimeout = 100 seconds ConnectionPool: (JDBC Property) Password = dbpassword ConnectionPool: (JDBC Property) User = dbadmin ConnectionPool: Registering org.gjt.mm.mysql.Driver java.sql.SQLException: No suitable driver at java.sql.DriverManager.getConnection(DriverManager.java:532) at java.sql.DriverManager.getConnection(DriverManager.java:171) at db.ConnectionPool.fillPool(Unknown Source) at db.ConnectionPool.createPool(Unknown Source) at db.ConnectionPool.initialize(Unknown Source) at db.ConnectionPool.initialize(Unknown Source) at db.ConnectionServlet.init(Unknown Source) at

I've gone through several interations on different $CLASSPATH combinations but haven't found anything to be useful. Here's the $CLASSPATH that is being passed to tomcat:

Jun 6 12:14:57 myserver su(pam_unix)[870]: session closed for user tomcat4 Jun 6 12:14:57 myserver su: dtomcat4:

What's most strange is this particular server was working fine the other day, but when when we shutdown and started tomcat again, the jdbc connection would not come back up. I've got 2.0.8 installed in the servlet lib directory as well as 2.0.14 in $JAVA_HOME/jre/lib/ext/ as described in the README. I am all out of ideas as to why the jdbc connection will not come back up. Tomcat runs fine. The servlet runs fine, except the module that requires the jdbc connection. Any help would be greatly appreciated.
