Hi all,
Tomcat 5.0.28 with Pointbase - Trying to obtain a database connection
from the DataSource.
I saw a zillion places in the web where they've discussed a problem
quite similar to the exception shown below BUT, none exactly like what I'm
experiencing. And by the way, I couldn't even find one case where they were
trying to connect with Pointbase. I followed documentation from all over the
web, but I don't see anything that I could be missing. To explain, many have
complained about null values for class and URL in the exception message that
you see below, but I don't have that problem. What could be wrong?
I have spent 5 hours trying to fix this.
(It is not even a case of the JDBC driver not being located as I get a
different error message when I remove the JDBC driver .jar files
(pbclient.jar). Pointbase is up and running on port 9092. Funny thing is the
same error message comes up whether Pointbase is running or not.)
Please HELP !!
Exception :
org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of
class 'com.pointbase.jdbc.jdbcDataSource' for connect URL
'jdbc:pointbase:server://localhost:9092/dbCompany'
