Re: [jetty-users] Getting JNDI/ db connection pool to work
By the way, I notice the 'Jetty dependencies site' is broken, and the jndi intro page that mentions it looks out of date.
Why isn't the source for jetty-jndi.jar in the distribution? It would be easier to debug. I found the jar on maven and got it via my build.gradle:

    compile group: 'org.eclipse.jetty', name: 'jetty-jndi', version: '9.3.0.v20150612'

But now it gives me this on lookup:

09:25:46.627 [qtp1963387170-11] ERROR com.priot.servlet.GetSession - Naming
javax.naming.NameNotFoundException

I wonder if this I got from the doc is right, since it defines the name - what about the empty first arg?
Hm - it uses jetty.plus but jetty-plus.jar seems to be a thing of the past (see note on out of date page above - jetty-plus.jar seems to have ended w/ v7 in maven central). Another odd thing is that the name is in the Arg, not in the id, which is normally what I'd expect to use to look up an object:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <New id="prDataSource" class="org.eclipse.jetty.plus.jndi.Resource">
   <Arg></Arg>
   <Arg>jdbc/pr</Arg>
   <Arg>
    <New class="com.mchange.v2.c3p0.ComboPooledDataSource">
       <Set name="driverClass">com.mysql.jdbc.Driver</Set>
       <Set name="jdbcUrl">jdbc:mysql://localhost:3306/pr</Set>
       <Set name="user">user</Set>
       <Set name="password">pwd</Set>
    </New>
   </Arg>
  </New>
</Configure>
Thanks,
Bill

Looks to me that you don't have jetty-jndi.jar on the classpath - it
contains the jndi impl.

It's as if my jetty-env.xml isn't being seen? But it is there in the war
file (along with the .swp).

Am I missing something obvious?

Thanks,
Bill
