Subject: databases and JNDI resource problem
From: guido schnider <[EMAIL PROTECTED]>
===
While trying to connect a mysql DB with Tomcat 4.0.4-b1 ant struts 1.x
as described in the Tomcat manual under JNDI Resources HOW-TO
I get the following error. It looks like that he is still looking for
the HypersonicDriver as in the example, but i changed it.
Any ideas or working examples?
Thanks!
TyrexDataSourceFactory: Cannot create DataSource, Exception
java.lang.ClassNotFoundException: org.hsql.jdbcDriver
PS: What is the smartest way working with Db's and tomcat/struts?
