Jetty: How to change startup temp directory

Question

I\'m trying to deploy a vaadin application to jetty.

But when I run jetty using start.jar, it starts to a subfolder of

C:\\Users\\USERNAM

Jetty needs a working directory.

Its search order for finding a work directory is as follows:

1. If the WebAppContext has a temp directory specified, use it.
2. If the ServletContext has the javax.servlet.context.tempdir attribute set, and if directory exists, use it.
3. If a ${jetty.base}/work directory exists, use it (only valid for Jetty 9.1+)
4. If a ${jetty.home}/work directory exists, use it.
   • Note: starting with Jetty 9.1 this test is now ${jetty.base}/work
5. If a ServletContext has the org.eclipse.jetty.webapp.basetempdir attribute set, and if the directory exists, use it.
6. Use System.getProperty("java.io.tmpdir") and use it.

The easiest one is either #3 or #4, just create a work directory underneath your ${jetty.home} or ${jetty.base} and restart Jetty.

The next easiest is #6, to specify your own java.io.tmpdir when you start the JVM for Jetty.

[jetty-distribution]$ java -Djava.io.tmpdir=/var/web/work -jar start.jar

The rest require you to configure the context for that deployed webapp.

Example for Jetty 7 or Jetty 8:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN"
                           "http://jetty.mortbay.org/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath"><Property name="foo"/></Set>
  <Set name="war">/var/web/webapps/foo.war</Set>
  <Set name="tempDirectory">/var/web/work/foo</Set>
</Configure>

Example for Jetty 9 (just a dtd change):

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN"
                           "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath"><Property name="foo"/></Set>
  <Set name="war">/var/web/webapps/foo.war</Set>
  <Set name="tempDirectory">/var/web/work/foo</Set>
</Configure>
