I have modified hibernate.cfg.xml, persistence.xml, testDS1.xml, jbpm-human-task-5.1.0.Final.jar and I am able to export the jbpm schema in my sql tables. 4 new tables : eventtypes, processinstanceinfo,sessioninfo, workiteminfo got created into the database named jbpm_demo within mysql. However when i try to open the console i get the above exception. I think the exception is comming due to modifications required in jbpm-human-task-5.1.0.Final.jar . Did anyone face the similar exception (Exception stack trace @ bottom) Here is the information from the modified files @ the time of exception: jbpm-human-task-5.1.0.Final.jar: persistence.xml : <properties>       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>       <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>       <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/JBPM_DEMO?useUnicode=true&amp;characterEncoding=UTF-8" />       <property name="hibernate.connection.username" value="root"/>       <property name="hibernate.connection.password" value=""/>       <property name="hibernate.connection.autocommit" value="false" />       <property name="hibernate.max_fetch_depth" value="3"/>       <property name="hibernate.hbm2ddl.auto" value="create" />       <property name="hibernate.show_sql" value="false" />     </properties> Hibernate.cfg.xml :   <session-factory>         <!-- Database connection settings -->         <property name="connection.driver_class">com.mysql.jdbc.Driver</property>         <property name="connection.url">jdbc:mysql://localhost:3306/jbpm_demo?useUnicode=true&amp;characterEncoding=UTF-8</property>         <!--property name="connection.url">jdbc:h2:file:/NotBackedUp/data/mydb</property-->         <property name="connection.username">root</property>         <property name="connection.password"></property>         <!-- JDBC connection pool (use the built-in) -->         <property name="connection.pool_size">1</property>         <!-- SQL dialect -->         <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>         <!-- Enable Hibernate's automatic session context management -->         <property name="current_session_context_class">thread</property>         <!-- Disable the second-level cache  -->         <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>         <!-- Echo all executed SQL to stdout -->         <property name="show_sql">false</property>         <!-- Drop and re-create the database schema on startup? -->         <property name="hbm2ddl.auto">create</property>         <mapping resource="AuditLog.hbm.xml"/>     </session-factory> Persistence.xml : <persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">     <provider>org.hibernate.ejb.HibernatePersistence</provider>     <jta-data-source>java:jdbc/jbpmDatasource</jta-data-source>          <mapping-file>META-INF/JBPMorm.xml</mapping-file>     <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>     <class>org.drools.persistence.info.SessionInfo</class>     <class>org.drools.persistence.info.WorkItemInfo</class>     <properties>       <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>              <property name="hibernate.max_fetch_depth" value="3"/>       <property name="hibernate.hbm2ddl.auto" value="create" />       <property name="hibernate.show_sql" value="false" />       <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />     </properties>         </persistence-unit> TestDS1.xml : <local-tx-datasource>     <jndi-name>jdbc/jbpmDatasource</jndi-name>     <connection-url>jdbc:mysql://localhost:3306/jbpm_demo?useUnicode=true&amp;characterEncoding=UTF-8</connection-url>     <!--connection-url>jdbc:h2:mem:mydb</connection-url-->     <driver-class>com.mysql.jdbc.Driver</driver-class>     <user-name>root</user-name>     <password></password>   </local-tx-datasource> EXCEPTION STACK TRACE 25.07.2011 18:56:43 INFO  [Configuration] Reading mappings from resource : META-INF/JBPMorm.xml 25.07.2011 18:56:43 INFO  [QueryBinder] Binding Named query: ProcessInstancesWaitingForEvent => select processInstanceInfo.processInstanceId from ProcessInstanceInfo processInstanceInfo where :type in elements(processInstanceInfo.eventTypes) 25.07.2011 18:56:43 INFO  [AnnotationBinder] Binding entity from annotated class: org.jbpm.persistence.processinstance.ProcessInstanceInfo 25.07.2011 18:56:43 INFO  [EntityBinder] Bind entity org.jbpm.persistence.processinstance.ProcessInstanceInfo on table ProcessInstanceInfo 25.07.2011 18:56:43 INFO  [AnnotationBinder] Binding entity from annotated class: org.drools.persistence.info.SessionInfo 25.07.2011 18:56:43 INFO  [EntityBinder] Bind entity org.drools.persistence.info.SessionInfo on table SessionInfo 25.07.2011 18:56:43 INFO  [AnnotationBinder] Binding entity from annotated class: org.drools.persistence.info.WorkItemInfo 25.07.2011 18:56:43 INFO  [EntityBinder] Bind entity org.drools.persistence.info.WorkItemInfo on table WorkItemInfo 25.07.2011 18:56:43 INFO  [HibernateSearchEventListenerRegister] Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath.
