Terracotta Discussion Forums

Hi, I followed the docs on the express setup, but I can't get it working.

I've started the terracotta server with defaults (start-tc-server.bat)

I've bundled into my ear file all the required jars

Here's my persistence.xml:

Code:

 <?xml version="1.0" encoding="UTF-8" ?>
 <persistence version="2.0"
 	xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
 	<persistence-unit name="pciPU" >
 		<provider>org.hibernate.ejb.HibernatePersistence</provider>
 		<jta-data-source>java:/pciDS</jta-data-source>
 		<properties>
 			<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>			
 			<property name="hibernate.show_sql" value="true" />
 			<property name="hibernate.format_sql" value="true" />
 			<property name="hibernate.cache.region.factory_class" value="net.sf.ehcache.hibernate.EhCacheRegionFactory" />
 			<property name="hibernate.cache.use_second_level_cache" value="true" />
 			
 		</properties>
 	</persistence-unit>
 </persistence>

And here's my ehcache config:

Code:

<?xml version="1.0" encoding="UTF-8"?>
 <ehcache name="pciCache">
 <terracottaConfig url="localhost:9510" />
 	<defaultCache
       maxElementsInMemory="1000"
       eternal="false"
       timeToIdleSeconds="120"
       timeToLiveSeconds="120">
       <terracotta/>
     </defaultCache>
 	<cache name="com.ericsson.oss.one.pci.model.Cell"
 		maxElementsInMemory="10000" eternal="true">
 	<terracotta/>
 	</cache>
 	<cache name="com.ericsson.oss.one.pci.model.Cell.outgoingRelations"
 		maxElementsInMemory="100000" eternal="true" >
 	<terracotta/>
 	</cache>
 	<cache name="com.ericsson.oss.one.pci.model.Cell.incomingRelations"
 		maxElementsInMemory="100000" eternal="true" >
 	<terracotta/>
 	</cache>
 </ehcache>

I've put the license file inside my ejbjar so it can be loaded by the classloader

When I deploy the application I get this error:

Can't find what I'm missing here. From what I read, bootjar should not be needed for the express setup (without DSO) right? All I need is a distributed cache, I think I would not need DSO right?

We are evaluating terracotta vs gemfire vs coherence. Any help would be great.

It seems to be cross post of the same issue here http://forums.terracotta.org/forums/posts/list/0/6203.page#31661.

We suggest trying with out nightly kit for the upcoming release. Support for Jboss6.x was added to it. JBoss 7 is not officially supported yet but might work if there's no major change in JBoss API.

Please try again with this kit http://tcnightly.s3.amazonaws.com/terracotta-3.6.0-2011-11-07_08-00-20.tar.gz
