I do struggle with the following situation:

I have an Equinox based server, running OSGI Jetty hosting a webapp employing spring. The Equinox server already uses gemini naming to provide the non-jta-data-source to eclipselink, which works perfectly.

Now I want to pass this DataSource to the spring application. My research so far brought me to the following steps:

* Register the datasource with JNDI
** Employ gemini naming for this
* Register a reference within web.xml for the web-application
** Activate JNDI initialization for jetty via jetty-web.xml
		<Item>org.eclipse.jetty.plus.webapp.EnvConfiguration</Item>
<Item>org.eclipse.jetty.plus.webapp.PlusConfiguration</Item>

** Add the resource in web.xml
<resource-ref>
		<description>Elexis DB Connection</description>
		<res-ref-name>osgi:service/jdbc/poolable</res-ref-name>
		<res-type>javax.sql.DataSource</res-type>
		<res-auth>Container</res-auth>
	</resource-ref>

* Reference the DataSource out of the spring-application
<bean id="dataSourceElexis" class="org.springframework.jndi.JndiObjectFactoryBean">
		<property name="jndiName" value="jdbc/poolable">
		</property>
	</bean>



This all does not look to bad - but I can't seem to figure out the following: Why does gemini naming not care for "java:comp"?

I get the following exception when initializing org.eclipse.jetty.plus.webapp.EnvConfiguration.createEnvContext
