Re: [vtp-dev] Database access via the VTP
Title: Re: [vtp-dev] Database access via the VTP
The JNDI connection mechanism in the exported webapp is designed to access resources configured at the server level or at the application level via the server.xml configuration file.  Since the our exported applications are archived into .war files, the per-application configuration in the WEB-INF/web.xml approach is not applicable.  The how-to located at:

    http://tomcat.apache.org/tomcat-5.5-doc/jndi-resources-howto.html

should be able to guide you to the correct location for your resource definitions.  This way your  configuration will survive updates and can also be shared across several applications if necessary.

I am finding the database access in the VTP to be hard to work with.
 
I am using the current baseline and Eclipse 3.4.2 and it seems that when I want to use JNDI to connect to my database that I have to deploy the application, then manually update the web.xml file for my application to insert a <resource-ref> entry. Then I have to create a context file for my application with the required “Resource” entry down inside the Tomcat folders on my application server. Once all that is done I can connect to my database and it works OK from there on.
 
I can see that I can add my web.xml entries to the org.eclipse.vtp.desktop.projects.core/resources/web.xml file and then they will appear in my deployed application. However Tomcat is destroying my context file which I then have to recreate every time I deploy my application. I’m guessing that I can stop this file deletion from happening by taking Tomcat off of auto-deploy – but that is a guess.
 
Is someone working on getting this database action to work so that it is more ‘wizard-like’ and does not require so much manual intervention?
 
Thanks,
Tom
