This is the web.xml entry:always perform such a lookup successfully, but when I try from a
ContextListener contextInitialized method it fails: the same code WILL
NOT FAIL contextDestroyed !!!
Hmmm, odd. This is *exactly* what I do pretty much. I have a LifeCycleListener specified in the webapps/<app>/WEB-INF/web.xml like this:
<listener> <listener-class><my.foo.bar.package>.LifeCycleListener</listener-class> </listener>
and then in the contextInitialized method of the LifeCycleListener I do a bunch of calls to jndiContext.lookup().
Hmm, hmmm, hmmm. You are correctly specifying the listener in web.xml?
<listener>
<listener-class>it.masterhouse.termopoli.web.startup.Init</listener-class>
</listener>
<resource-ref>
<description>

<res-type>
javax.sql.Datasource
</res-type>

</res-auth>
</resource-ref>and this is the context:

I can list the JNDI datasource like this:

but then:

I think the problem is that I cannot get the ResourceParameters: look at a succesfull call:

This is in accordance with the fact that when I tried to deploy the application from webapps putting termopoli.xml and termopoli.war in CATALINA_HOME\webapps, server.xml was modified to include the <Resource> tag but the <ResourceParams> where left out:
<Context className="org.apache.catalina.core.StandardContext" cachingAllowed="true" charsetMapperClass="org.apache.catalina.util.CharsetMapper" cookies="true" crossContext="false" debug="0" displayName="Termopoli" docBase="C:\java\jakarta-tomcat-4.1.24\webapps\termopoli" mapperClass="org.apache.catalina.core.StandardContextMapper" path="/termopoli" privileged="false" reloadable="false" swallowOutput="false" useNaming="true" wrapperClass="org.apache.catalina.core.StandardWrapper">
<Resource auth="Container" description="JNDI resource reference to a factory for java.sql.Connection
instances that may be used for talking to Babele
database (configured in the server.xml file)." name="jdbc/Babele" scope="Shareable" type="javax.sql.Datasource"/>
</Context>
I'm surely missing some point ...
Thank you very much, Federico
