Hi ,

I am using a third party web application with jetty 7.6 . That third party web

app needs a datasource so I need to configure datasource in context.xml , here

is its content :

 

<Configure id='wac' class="org.eclipse.jetty.webapp.WebAppContext">

I have defined the resource in web.xml too

<resource-ref>

        <description>frevvo DB Data Source</description>

        <res-ref-name>jdbc/frevvoDS</res-ref-name>

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

        <res-auth>Container</res-auth>

      </resource-ref>

 

Can you tell me where I am doing wrong step and let me know if I have missed

any step.

 

Reproducible: Always

 

Steps to Reproduce:

1.Configure datasource in context.xml

2.Start the server.

 

 

I tried to contact jetty guys , they told me Try to not specify the scope by
removing the reference to wac:
 
Change:
<Arg><Ref id="wac"/></Arg>
 
To:
<Arg></Arg>

 

 

I tried this but this haven’t resolved the problem. I am getting the same error. Please help ASAP!!!!

 

Thanks

Sandeep
