Subject Re: Problem configuring JNDI DataSource for Oracle
Date Thu, 22 Jun 2006 19:54:22 GMT
Ashvini,

I have faced a similar problem. Instance of the JNDI resource is not being created. In my
case, the solution was to remove any spaces tomcat's path. I moved Tomcat directory from c:\Program
Files\Apache Software Foundation\Tomcat to c:\Tomcat. JDK has a bug that it cannot find JNDI
resource when there is a space in the path. See if that works for you.

Regards,

Sourabh

Nope, with that it only gives a proper error message,
Invalid connection string format, a valid format is: "host:port:sid"
