RE: [OT] Using tomcat7-maven-plugin- 2.0-beta-1: java.lang.RuntimeException: Name jdbc is not bound in this Context

[Guofeng Zhang <gu...@radvision.com>]

I create a simple project using commons-dbcp and without using any query for test, the issue still occurred. I reported a bug.

Thanks!

You might want to use a simper testQuery (like "SELECT 1 FROM DUAL", for instance). Some RDBMS engines don't have great performance with "SELECT COUNT(*)" (for instance, MySQL using the InnoDB engine).

Also, does your factory generate a DataSource for which "testQuery" is a valid property? If you are using Tomcat's standard connection poll (DBCP's BasicDataSource) or Tomcat's "other" pool (jdbc-pool), then the proper configuration attribute is "validationQuery".

See
http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html#JDBC_Data_Sources

Specifically, step #4 under that heading.
