Re: [jetty-users] Question for JDBC JNDI look up issue

[Joakim Erdfelt <joakim@xxxxxxxxxxx>]

org.eclipse.jetty.util.annotation.ManagedObject is for JMX MBean support.

Using Server.addManaged(MyAbstractLifeCycle) will just start your bean after the other beans in the Server.

Perhaps you want to just start your server services anyway, completely outside of the Server instance lifecycle.

If you have no need to access anything from your server services, then there's no need to include them as a bean (or an attribute) on the Server.

Just start them before Server.start() is called.

Hi Team,

 

I’m not sure if I’m mailing the correct alias but I’ve a question about Jetty usage.

 

I’m currently trying to build up applications based on standalone Jetty and have a requirement that, some of the server services need be started before the war applications are deployed and started to provide general services for the deployed applications.

 

I tried to create a class which inherits “org.eclipse.jetty.util.component.AbstractLifeCycle” with annotation “@ManagedObject”, and also, it is injected by adding definitions into jetty.xml like below:

 

    <Call name="addManaged">

      <Arg>

        <New class="oraclel.ocsg.jetty.trial.MyAbstractLifeCycle"/>

      </Arg>

    </Call>

 

And, within the class, I need get access to the JDBC connection data source. I checked the document and found that, for applications, it is required to add the jdbc resource reference into the web.xml. While for my case, I don’t know how to get the data source. I tried to lookup JNDI in the MyAbstractLifeCycle class I created, but it failed.

 

Below is my JDBC connection pool definition in the jetty.xml:

 

    <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">

     <Arg></Arg>

     <Arg>jdbc/DSTest</Arg>

     <Arg>

        <New class="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource">

           <Set name="Url">jdbc:mysql://10.182.12.146:3306/linren</Set>

           <Set name="User">ocsgtest</Set>

           <Set name="Password">123456</Set>

        </New>

     </Arg>

    </New>

 

Can anyone tell me how to get the JDBC connection from the inherited class MyAbstractLifeCycle?

 

Thanks!

 

Lin
