The Weblogic servers we are using have been configured to allow JNDI datasource names

  • 0

The Weblogic servers we are using have been configured to allow JNDI datasource names like ‘appds’.

For development (localhost), we might be running Tomcat and when declared in the <context> section of server.xml, Tomcat will hang JNDI datasources on ‘java:comp/env/jdbc/*’ in the JNDI tree.

Problem: in Weblogic, the JNDI lookup is ‘appds’ whilst in Tomcat, it seems that that I must provide the formal ‘java:comp/env/jdbc/appds’. I’m afraid the Tomcat version is an implicit standard but unfortunately, I can’t change Weblogic’s config … so that means we end up with two different spring config files (we’re using spring 2.5) to facilitate the different environments.

Is there an elegant way to address this. Can I look JNDI names up directly in Tomcat? Can Spring take a name and look in both places? Google searches or suggestions would be great.

  1. JndiLocatorSupport has a property resourceRef. When setting this true, ‘java:comp/env/’ prefix will be prepended automatically. So I believe it would be correct to differentiate this parameter when moving from Tomcat to Weblogic.
