Hi Jan,
That section is a lot easier to help standard "official" eclipse
distribution users get up and running with JNDI!
Originally thought the start.ini OPTIONS=plus, etc would load the JNDI
support, and because the distribution start.ini configuration options
didn't have that /etc/jetty-plus line present at all (unlike other
commented out config files) I wasn't aware that I needed to add it to
activate the jars that were put on the OPTIONS line.
I come from using primarily Tomcat, and had a bit of a time navigating
through the Wiki and examples on the net.
Some of them reporting having to use jetty-web.xml not the jetty-env.xml
probably because of a similar configuration issue, so this should help
people just starting out with Jetty.
The only other suggestions I would make for the Wiki is to give a
concrete example for the <resource-ref> under "Configuring DataSources"
for instance after:
> If you have the appropriate |<resource-ref>| setup in your |web.xml|,
> then it is available from application lookups as
> |java:comp/env/jdbc/myds|.
It would be nice to give a simple code example:
<resource-ref>
<description>Example Datasource reference</description>
<res-ref-name>jdbc/myds</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
(I was a bit confused by the <Arg><Ref id="wac"/></Arg> in the example,
I didn't know where/if I needed to reference this in
the web.xml <resource-ref>)
On a side note, I noticed in the "Configuring Links" section it seems
like the the example for the jetty-env.xml section got mangled in with
the context.xml file example.
See the second code block section above "Setting JNDI Entries as Global
or Scoped" section
it looks like the "in a <code>jetty-env.xm</code>l file: .." got mashed
in with the context xml file.
Thanks,
Jamie
