"Re: how to install the jbpm5 to work on mysql database" To view the discussion, visit: http://community.jboss.org/message/617735#617735 -------------------------------------------------------------- Hello Everyone, I am getting an exception when configuring jbpm 5.1 on jboss 5.1 with mysql 5.1. 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&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&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&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.
