No hot deployment in Jetty 9.0.6 - jetty

Question

I have set up a Jetty context by a context.xml for using virtual hosts. So my directory structure looks like this:
webapps
--mycontext.xml
--mycontext.war
Now when i upload a new war, no hot deployment occurs any more. It only happens when i modify mycontext.xml. That was not the case when i worked without a mycontext.xml.
Here is the content of mycontext.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<!-- Required minimal context configuration : -->
<!-- + contextPath -->
<!-- + war OR resourceBase -->
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<Set name="contextPath">/</Set>
<Set name="war"><Property name="jetty.webapps" default="."/>/mycontext.war</Set>
<Set name="virtualHosts">
<Array type="String">
<Item>example.com</Item>
<Item>www.example.com</Item>
<Item>localhost</Item>
<Item>127.0.0.1</Item>
</Array>
</Set>
</Configure>
Any ideas how i regain hot deployment by updating the war file?

You need to put your mycontext.xml in the contexts directory of your server. Also you probably need to enable hot deployment in etc/jetty-deploy.xml for the war files in webapps directory as mentioned here. As you can see the configuration enables the hot deployment
......
<Set name="monitoredDirName"><Property name="jetty.home" default="." />/webapps</Set>
.....
Following is the configuration which is working for me
jetty.home/contextx/mycontext.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<!-- Required minimal context configuration : -->
<!-- + contextPath -->
<!-- + war OR resourceBase -->
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -->
<Set name="contextPath">/mycontext</Set>
<Set name="war"><SystemProperty name="jetty.home"/>/webapps/mycontext.war</Set>
<Set name="virtualHosts">
<Array type="String">
<Item>example.com</Item>
<Item>www.example.com</Item>
<Item>localhost</Item>
<Item>127.0.0.1</Item>
</Array>
</Set>
</Configure>
Please note how I have supplied the war file name and location
<Set name="war"><SystemProperty name="jetty.home"/>/webapps/mycontext.war</Set>
jetty.home/etc/jetty-deploy.xml
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

With this configuration, when I put a modified mycontext.war in webapps, jetty happily
redeploys the war.
