Now i want to integrate jbpm and seam on tomcat6 and i have the jbpm 3.2.7. and i have configured the hibernate.cfg.xml like:     <!-- hibernate dialect -->     <property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>     <!-- JDBC connection properties (begin) -->    <!--      <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>     <property name="hibernate.connection.url">jdbc:oracle:thin:@132.10.18.248:1521:siga</property>     <property name="hibernate.connection.username">seamt</property>     <property name="hibernate.connection.password">seamt</property> -->     <!-- JDBC connection properties (end) -->     <!-- DataSource properties (begin) -->     <property name="hibernate.connection.datasource">java:comp/env/jdbc/SigaDS</property>     <!--  DataSource properties (end) --> jbpm.cfg.xml like: <jbpm-configuration>   <jbpm-context>     <service name="persistence">        <factory>           <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">              <field name="isTransactionEnabled"><false/></field>           </bean>        </factory>     </service>     <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />     <service name="message"
