caching - jpa hibernate and 2nd level cache -

-

my configuration follows

persitence.xml

<property name="hibernate.cache.provider_class" value="org.hibernate.cache.singletonehcacheprovider"/> <property name="hibernate.ejb.classcache.demo.entities.userid" value="read-only"/> <property name="javax.persistence.sharedcache.mode" value="all"/>

ehcache.xml

<?xml version="1.0" encoding="utf-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"          xsi:nonamespaceschemalocation="http://ehcache.org/ehcache.xsd" updatecheck="false">     <diskstore path="java.io.tmpdir/customer-portlet-cache"/>      <defaultcache eternal="false" maxelementsinmemory="1000"                   overflowtodisk="false" diskpersistent="false" timetoidleseconds="0"                   timetoliveseconds="600" memorystoreevictionpolicy="lru"/>     <cache name="usercache" eternal="true"            maxelementsinmemory="999" overflowtodisk="true"            diskpersistent="true" timetoidleseconds="0"            timetoliveseconds="300" memorystoreevictionpolicy="lru"/> </ehcache>

i have seam component annotated @create gets listing userid , stores them away cache. idea here application warm cache, when access entities application start getting lazy initialization exceptions allover (because entity not associated persistencecontext , has onetomany , manytomany relations , not load entity , if set fetchtype eager more nasty areas)

is there way or workaround getting warm cache when users accesses applications.

don't manually access 2nd level cache. if need separate caching layer, make new one, different hibernate's.

in case, can hibernate.initialize(..) entities , collections before putting/sending them anywhere

and finally, don't think 2nd level cache configured properly. newer version should this:

<property name="hibernate.cache.use_second_level_cache" value="true" /> <property name="hibernate.cache.region.factory_class"             value="net.sf.ehcache.hibernate.singletonehcacheregionfactory" />

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
