I'm trying to set up a data source and access it from a web app. I guess I need to somehow deploy a tranql service? If there's an example somewhere it would be helpful. I think if I get the database in the global JNDI space then I can use a resource-env-ref in web.xml and a
naming:resource-env-ref in geronimo-jetty.xml and that should put it in my web app's local JNDI space.
Thanks, Aaron
There is an example system-database-plan.xml that defines a DataSource for accessing the embedded Derby database. This uses the generic JDBC connector from TranQL and can be adapted to other vendor's drivers as needed. You use the same RAR file, just different deployment plans.
To access from a web app you need a <resource-ref> not a <resource-env-ref> - the Jetty plan looks like:
<web-app xmlns="http://geronimo.apache.org/xml/ns/web/jetty"; configId="my_wars_config_id">
<context-priority-classloader>false</context-priority-classloader>
<resource-ref>
<ref-name>jdbc/myDB</ref-name>
<target-name>myDatasource</target-name>
</resource-ref>
</web-app>where <target-name> is the name of your datasource.
If you don't want an additional RAR config, I think you can actually embed its plan inside your geronimo-jetty.xml definition. Basically copy the <resource> element from the RAR plan and put it at the end of your web-app element (I know this works for app-clients).
