i have the same problem too.
I try run Apache Roller 3.1 on SAP WebAs 7.
My hibernate config:
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- You can override this via the jdbc.XXX properties in roller-custom.properties --> <property name="connection.url">jdbc:mysql://localhost:3306/rollerdb</property> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.username">scott</property> <property name="connection.password">tiger</property> <!-- You can override this via the hibernate.dialect property in roller-custom.properties --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">false</property> <!-- use thread local Session context --> <property name="hibernate.current_session_context_class">thread</property> <!-- Hibernate L2 Caching --> <property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property> <property name="hibernate.generate_statistics">true</property> <property name="hibernate.cache.use_structured_entries">true</property> <!-- Delegate Hibernate?s transactions to the J2EE-Engine?s JTA --> <property name="transaction.factory_class"> org.hibernate.transaction.JTATransactionFactory </property> <property name="transaction.manager_lookup_class"> org.hibernate.transaction.SAPWebASTransactionManagerLookup </property> <!-- Map Roller pojo classes --> <mapping resource="org/apache/roller/pojos/RollerPropertyData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/UserData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/RoleData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/RollerConfigData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WebsiteData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/PermissionsData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/BookmarkData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/CommentData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/FolderAssoc.hbm.xml" /> <mapping resource="org/apache/roller/pojos/FolderData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogTemplate.hbm.xml" /> <mapping resource="org/apache/roller/pojos/PingCategoryRestrictionData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/AutoPingData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/PingQueueEntryData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/PingTargetData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/RefererData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/TaskLockData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/HitCountData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogEntryData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogEntryTagData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogEntryTagAggregateData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/EntryAttributeData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogCategoryData.hbm.xml" /> <mapping resource="org/apache/roller/pojos/WeblogCategoryAssoc.hbm.xml" /> <mapping resource="org/apache/roller/planet/pojos/PlanetConfigData.hbm.xml" /> <mapping resource="org/apache/roller/planet/pojos/PlanetGroupData.hbm.xml" /> <mapping resource="org/apache/roller/planet/pojos/PlanetEntryData.hbm.xml" /> <mapping resource="org/apache/roller/planet/pojos/PlanetSubscriptionData.hbm.xml" /> </session-factory> </hibernate-configuration>

Also, i have message in roller log:
