Context (webapp) configuration in GlassFish

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.

&lt;Context&gt;<br>
  &lt;Environment name="global_environment" type="java.lang.String" value="global_environment_value"/&gt;<br>
&lt;/Context&gt;

&lt;virtual-server id="server" ... &gt;<br>
&lt;property name="<strong>contextXmlDefault</strong>"
value="config/context.xml.default"/&gt;<br>
&lt;/virtual-server&gt;

&lt;Context&gt;<br>
  &lt;Environment name="webapp-env" type="java.lang.String" value="webapp-env-value"/&gt;<br>
  &lt;Resource name="jdbc/__default" auth="Container"
            type="javax.sql.DataSource"
     description="Default Database"/&gt;<br>
&lt;/Context&gt;
