JDBC connection through JNDI

["Hehl, Thomas" <Th...@acs-inc.com>]

I wish to create a JDBC connection and store it in a JNDI tree for use by a
spring configuration file that usually runs my tomcat webapp. I'm trying to
figure out how tomcat creates the connection pool from my config file and
stores it in JNDI, but it is absolutely beyond me.

 

I've googled and looked through the source code and am nearly lost.

 

Thanks.

Do you want to configure this, or understand how it works? Those are very 
different aims.

Hello,

here's one document for you to read - unless you've already seen it:
http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html#Adding%20Custom%20Resource%20Factories

That tells one part of JNDI resource construction. In the most cases you wouldn't
even need your own resource factory, but can rely on those supplied with Tomcat,

For JDBC resources, the documentation looks like it uses some heuristics to
choose org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory as the resource
factory to use (perhaps by looking at the "type" attribute of the resource
definition) and the other attributes from the resource definition are passed to the
factory class, which uses them to set properties on the resource to be created.

Perhaps, if you could elaborate on what exact information you're looking for (and
for what purpose), you might get more on-spot answers.
