Multiple Contexts - one classloader

[Shanti Suresh <sh...@umich.edu>]

All,

Is there a way to specify with Tomcat 7, one webapp-base with multiple contexts?  If I create several XML files under <tomcat-home>/conf/Catalina/localhost/ and point the docbase to outside-appbase WAR path I get multiple classloaders.  I would like one application instance to serve the different contexts.  Is that possible?  An example of three context XML files follows.  But I get three classloaders and multiple deployments:

siteA.xml:

<Context docBase="/opt/tomcat/killerApp" path="/siteA" crossContext="true"
         clearReferencesHttpClientKeepAliveThread="true"
         clearReferencesStopTimerThreads="true"
         swallowOutput="true" />


siteB.xml:

<Context docBase="/opt/tomcat/killerApp" path="/siteB" crossContext="true"
         clearReferencesHttpClientKeepAliveThread="true"
         clearReferencesStopTimerThreads="true"
         swallowOutput="true" />


siteC.xml:

<Context docBase="/opt/tomcat/killerApp" path="/siteC" crossContext="true"
         clearReferencesHttpClientKeepAliveThread="true"
         clearReferencesStopTimerThreads="true"
         swallowOutput="true" />

Thanks.

                     -Shanti

Please read the servlet spec; one application == one context.  You can play games with forwarding if you want, or simply install just one webapp as ROOT (case sensitive) and remove the three site* <Context> elements.

As you should.  Each webapp is independent of the others, by definition.

Also, take out the path attributes in the three <Context> elements; that attribute is not allowed here.

I may regret asking: why do you want do this?
