It’s easy enough to tell JDeveloper that you want to deploy to Tomcat, it just needs the path to the webapps directory and forges on …
Tomcat Database connection pools
To get these with JDev you have to run Toplink, somehow persuade Orion (their embedded J2EE server) to run the naming service and all that jazz. I just wanted a simple thing with Tomcat, which is dead easy and does’t tie you up in Oracle knots.
After a lot of pain I eventually read the manual . Dead easy if you follow the instructions.
However you need to create a file called context.xml that lives in the META–INF directory.
Again – dead easy. Just create a META–INF directory under public_html in your JDev project folder and put it there. It just deploys.
Hope this helps the next Joe – took me most of several evenings to get to the bottom of it.
Have fun.
