Jetty is really nice, amongst the amazing things you can do some of my favorites are:
- Change java.io.tmpdir default value
- override params define in the web.xml embedded in a war file
java.io.tmpdir
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
<Set name="contextPath">/test</Set>
...
<!-- change java.io.tmpdir default value -->
<Call class="java.lang.System" name="setProperty">
<Arg>java.io.tmpdir</Arg>
<Arg>/some/where</Arg>
</Call>
</Configure>
Change default values in web.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
<Set name="contextPath">/test</Set>
...
<Set name="overrideDescriptor">
<SystemProperty name="jetty.home"
default="."/>/contexts/test.d/override-web.xml</Set>
</Configure>
Create an 'override-web.xml'
<?xml version="1.0" encoding="UTF-8"?>
<web-app ...>
<!-- Add or override context init parameter -->
<context-param>
<param-name>my.param/param-name>
<param-value>on</param-value>
</context-param>
</web-app>

The web.xml override feature originates from Joost: an idea of mine, written by Torsten and contributed back by Pier :-)
I knew it was heavily used at Joost.
I knew Pier contributed to Jetty.
But I didn't know it was your idea ;)
Well done :)
It would be great to have a little bit more descriptive override-web.xml file
Nice hint, thank you :)
We at jvmhost.com also use TMPDIR environment variable to set the directory Jetty wide.
I need to override a filter mapping on the original web.xml.. that can be done with this override feature ?
Supposedly yes ;)
