Web Application that shows this behavior
This occurs with 6.0 Trunk, built from SVN yesterday (2009-11-16):
I have a Servlet that's loaded on
startup and does following in its init() method:
try
{
Class.forName( driver );
}
catch( ClassNotFoundException x )
{
log( x.toString(), x );
}
Connection con = null;
try
{
con = DriverManager.getConnection( url, user, pass );
log( "connection established: " + con.toString() );
}
catch( SQLException x )
{
log( x.toString(), x );
throw new ServletException( x.toString(), x );
}
After starting Tomcat, I get the following expected output:
Nov 16, 2009 1:56:11 PM org.apache.catalina.core.ApplicationContext log
INFO: DBTestServlet: connection established:
org.postgresql.jdbc4.jdbc4connect...@17ec9f7
Nov 16, 2009 1:56:12 PM org.apache.catalina.core.ApplicationContext log
INFO: ContextListener: contextInitialized()
But when reloading the context, I get the following
exception:
Nov 16, 2009 1:56:32 PM org.apache.catalina.core.ApplicationContext log
SEVERE: DBTestServlet: java.sql.SQLException: No suitable driver found for
jdbc:postgresql://127.0.0.1/inxmail
java.sql.SQLException: No suitable driver found for
jdbc:postgresql://127.0.0.1/inxmail
at java.sql.DriverManager.getConnection(DriverManager.java:602)
at java.sql.DriverManager.getConnection(DriverManager.java:185)
at com.inxmail.test.DBTestServlet.init(DBTestServlet.java:49)
at javax.servlet.GenericServlet.init(GenericServlet.java:212)
I tested with Java 6 (1.6.0_17) and JDBC 3 and 4 Drivers for Oracle
(ojdbc1.4.jar from Oracle 10, ojdbc6 from Oracle 11) as well as PostgreSQL.
Attached is a minimal webapp that exhibits this behavior. DB connection
configuration is in /META-INF/context.xml. Also attached is the full source of
the servlet.
This webapp works in 6.0.20.
