java - Caches of all versions of a webapp deployed in parallel are shutdowned -


i use ehcache in webapp versions deployed in parallel on tomcat instance. handy way deploy new versions without stopping application.

i have problem way proceed : if give cache , disk store different names, depending on versions of webapp, all caches stopped when stopping one instance.

my config :

<?xml version="1.0" encoding="utf-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:nonamespaceschemalocation="ehcache.xsd" name="mywebapp-${project.version}_build_${buildnumber}"> <defaultcache     maxelementsinmemory="1000"     maxelementsondisk="10000"     eternal="false"     timetoliveseconds="300"     timetoidleseconds="300"     overflowtodisk="true"     diskpersistent="false"     memorystoreevictionpolicy="lru"     statistics="true" />  <cache     maxelementsinmemory="1000"     maxelementsondisk="10000"     name="org.hibernate.cache.internal.standardquerycache"     eternal="false"     timetoliveseconds="300"     timetoidleseconds="300"     overflowtodisk="true"     diskpersistent="false"     statistics="true"/>  <cache     name="org.hibernate.cache.spi.updatetimestampscache"     maxelementsinmemory="10000"     maxelementsondisk="100000"     timetoliveseconds="300"     timetoidleseconds="300"     eternal="false"     overflowtodisk="true"     diskpersistent="false"     statistics="true"/>  <cache     name="query.presences"     maxelementsinmemory="100"     maxelementsondisk="1000"     eternal="false"     timetoliveseconds="300"     timetoidleseconds="300"     overflowtodisk="true"     diskpersistent="false"     statistics="true"/>  <diskstore path="java.io.tmpdir/mywebapp-${project.version}_build_${buildnumber}"/>   </ehcache>

${project.version} , ${buildnumber}

being replaced maven during build process.

does know how avoid unwanted behaviour ?

i using ehcache-core-2.4.3 , hibernate-ehcache-4.3.8.

the way net.sf.ehcache.constructs.web.shutdownlistener works shutting down all cache managers.

so way work making sure cache managers end in different class loaders, ehcache loaded web application class loader , not container one.

do provide ehcache jar in app's web-inf/lib? if yes, sure there not ehcache in tomcat's classpath?

if solution still not work, may better off creating own servletcontextlistener shutdown cache manager containing application.
