JNDI-Context on Tomcat 5.5 [message #115942]

Hi,

I want to deploy my RAP app on an external server (Tomcat 5.5) using the
equinox servlet bridge. I need to instantiate the quartz scheduler and
have it to be communicating with a derby database, but I'm not able to
initialize the context (see the exception beneath).

Here is what I've already tried (without success):
- adding a folder "META-INF" to server-directory on the same level as my
project's WEB-INF-folder; this contains a "context.xml" where the context
is defined
- same context.xml renamed as myproject.xml copied into
jakarta-tomcat-5.5.9\conf\Catalina\localhost
- jakarta-tomcat-5.5.9\conf\server.xml: adding a resource with the
connection properties under "<GlobalNamingResources>"
- adding following code to my project's web.xml:
<resource-ref>
<description>Supplycare DB</description>
<res-ref-name>jdbc/quartz</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

here the jndi url that is given to the quartz-constructor with a few other
properties:
org.quartz.jobStore.dataSource = quartzDS1
org.quartz.dataSource.quartzDS1.jndiURL = java:comp/env/jdbc/quartz

The database is working fine in other (non-RAP) projects. Is it possible,
that the context is overwritten by any RAP-feature?

Thanks for your help.

Regards, Alex

This is doable albeit a bit complicated.

In most (if not all) of the JNDI implementations I'm aware of your context
is scoped by whatever your context class loader is.
In addition another thing to be aware of is that some app servers will only
permit JNDI lookup on the thread that originated the request. (If you're
curious, this is normally enforced by a security token store in a
thread-local).

To get at the various things you've set you need to set up a try/finally
block that:
1) saves the current context class loader
2) set the context class loader to the web app class loader (The approach I
suggest is to get it from org.eclipse.equinox.servletbridge.BridgeServlet --
something like BridgeServlet.class.getClassLoader())
3) Do your JNDI calls
4) reset the context class loader saved in step 1.
