I have an application that works in Jboss 4.2.3.GA, but doesn't work in Jboss5GA. This is the stacktrace (cleaned for readability: anonymous wrote : | WARN [EhCacheProvider] Could not find configuration [persistence.unit:unitName=foo.ear/bar-ejb.jar#foo-PU.be.foo.bar.domain.user]; using defaults. | ERROR [AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=foo.ear/bar-ejb.jar#foo-PU state=Create | java.lang.IllegalArgumentException: Cache name cannot contain '/' characters. | at net.sf.ehcache.config.CacheConfiguration.setName(CacheConfiguration.java:163) | at net.sf.ehcache.Cache.setName(Cache.java:1721) | at net.sf.ehcache.CacheManager.addCache(CacheManager.java:632) | at org.hibernate.cache.EhCacheProvider.buildCache(EhCacheProvider.java:94) I think this is caused by the not working of the jboss.entity.manager.factory.jndi.name this is the persistence.xml: | <?xml version="1.0" encoding="UTF-8" standalone="no"?> | <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | version="1.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> | <persistence-unit name="foo-PU" transaction-type="JTA"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:fooDS</jta-data-source> | <properties> | <property name="jboss.entity.manager.factory.jndi.name" value="java:foo-PU" /> | <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" /> | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.EhCacheProvider" /> | <property name="hibernate.cache.use_query_cache" value="true" /> | <property name="hibernate.cache.use_second_level_cache" value="true" /> | <property name="hibernate.generate_statistics" value="false" /> | <property name="hibernate.cache.provider_configuration_file_resource_path" value="ehcache.xml"/> | </properties> | </persistence-unit> | </persistence> I'm using Spring 2.5.6 in the applicationContext I simply use: | <jee:jndi-lookup id="emf" jndi-name="java:foo-PU"/> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205784#...
