Yes ... I have done the following things .... 1. I have all the user,group and membership tables popluated properly in mysql db as in the default hsqldb. (this seems to be fine for me) 2. I have configured tomcat to use the mysql db. In the file ... WEB-INF\classes\hibernate.cfg.xml ... following modifications were made. <!-- hibernate dialect --> org.hibernate.dialect.MySQLInnoDBDialect <!-- JDBC connection properties (begin) --> com.mysql.jdbc.Driver jdbc:mysql://localhost:3306/jbpm32test root admin <!-- JDBC connection properties (end) --> org.hibernate.cache.HashtableCacheProvider <!-- DataSource properties (begin) --> java:/JbpmDS <!-- DataSource properties (end) --> Pls let me know if the hibernate properties are configured properly. Do I need a Datasource as mentioned above?(wan not there for jbpm 3.1.4) AND KINDLY LET ME KNOW THE RIGHT MINIMAL LIST OF THE JAR FILES NEEDED TO GET THIS WORKING.
