Context (webapp) configuration in GlassFish

Posted by amyroh on May 23, 2007 at 01:33 PM | Comments (6)

Deployment specific web application configuration using context.xml in GlassFish was added a couple of months ago but related questions keep coming up on mailing lists and forum so I've decided to blog about it so it's easy to point out. ;-)

Similar to Tomcat you can define your context.xml as follows.

1. Global context.xml glassfish/domains/domain1/config/context.xml which will be loaded by *all* webapps.

For example, global context.xml can define global environment entry to be shared across all webapps as follows.


<Context>

  <Environment name="global_environment" type="java.lang.String" value="global_environment_value"/>

</Context>

2. Virtual server context.xml specified by virtual-server property "contextXmlDefault" in domain.xml will be loaded by all webapps of this virtual server.

For examples, you can define contextXmlDefault for a virtual server in your domain.xml as follows.


<virtual-server id="server" ... >

<property name="contextXmlDefault"
value="config/context.xml.default"/>

</virtual-server>

3. Webapp specific context.xml will be loaded by this webapp only.

You can define /META-INF/context.xml in a WAR file for this webapp specific environment and resource definitions.


<Context>

  <Environment name="webapp-env" type="java.lang.String" value="webapp-env-value"/>

  <Resource name="jdbc/__default" auth="Container"
            type="javax.sql.DataSource"
     description="Default Database"/>

</Context>

GlassFish V2 Beta 2 or later should have this feature.

Cheers,
Amy

Would that work also using a "deployed" application or does that just work with war files?

I have not tried GF yet, but we don't use war files so that would be nice to have also.

You can put context.xml in your deployed webapp (META-INF/context.xml). You'll need to restart GlassFish for changes to take effect.

Thanks,
Amy

Fair enough, but how do I use it in my Java code??? I thought this goes into java/env but it doesn't work for me :-(
