Geronimo M5 JNDI resources
I would like to create some JNDI resources that can be configured as part
of a configuration file. Using Tomcat this can be achieved by configuring
the resource factory in the server.xml file (as shown below). How is it
recommended that this be achieved with Geronimo? I initially had two
thoughts, either this could be hosted by the embedded Tomcat and configured
using the geronimo-web.xml file it could be hosted as part of the openejb
component and configured using the openejb-jar.xml. Can anyone share some
advise?
<Context ...>
...
<Resource name="bean/MyBeanFactory" auth="Container"
type="com.mycompany.MyBean"/>
<ResourceParams name="bean/MyBeanFactory">
<parameter>
<name>factory</name>
<value>org.apache.naming.factory.BeanFactory</value>
</parameter>
<parameter>
<name>bar</name>
<value>23</value>
</parameter>
</ResourceParams>
...
</Context>
Thanks in Advance,

On first look, I would say this is not a use of jndi supported by the
j2ee spec, and that there is no direct support in geronimo for it at
this time. I'd be interested in knowing more about what you are trying
to do here and what the result of the jndi lookup is supposed to be.
It looks like you are trying to expose a javabean in jndi, each lookup
returning a new instance? The configuration of the javabean factory
could be done easily as a gbean, but there would be no direct way to
access it in jndi. We've discussed possible ways of exposing arbitrary
gbeans through jndi but due to lack of clear use cases and time nothing
is implemented at the moment.
As workarounds you might be able to use env-entries to let your j2ee
component construct the javabean itself or you might possibly be able
to do something by registering a custom URL handler that would create
the javabean for you.
