Configuration details: JBoss Server 5.1 (4 node cluster) Mysql 5.5 Heres what i did to migrate from HSQLDB to Mysql: 1. Copied the Mysql JDBC driver (mysql-connector-java-5.1.1.4-bin) to the lib folder of the nodes in JBoss. 2. Replacde the file hsqldb-ds.xml with mysql-ds.xml in the deploy folder in JBoss. 3. Replaced the file hsqldb-persistence-service.xml with mysqldb-persistence-service.xml in the messaging folder under deploy in JBoss. 4. Updated the file mysql-ds.xml to have the following:                              <local-tx-datasource> <jndi-name>defaultDS</jndi-name> <connection-url>jdbc:mysql://mysql-hostname:3306/jbossdb</connection-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <user-name>icdt</user-name> <password>icdt</password> <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation> <min-pool-size>20</min-pool-size>   <max-pool-size>100</max-pool-size> <security-domain>MySqlDbRealm</security-domain>         5.   Uncommented the "guest=guest" entry in the messaging-users file.    6.  Added the following in the login-config file present in jboss/conf folder:                <application-policy name = "MySqlDbRealm"> <authentication> <login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" flag = "required"> <module-option name = "principal">uname</module-option> <module-option name = "userName">uname</module-option> <module-option name ="password">pwd</module-option> <module-option name ="managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=DefaultDS</module-option> </login-module> </authentication> </application-policy>   7.  Added a reference to the MySqlDbRealm in the mysql-ds file by adding the following:                 +<security-domain>MySqlDbRealm</security-domain>+ +  8. + Ensured that the <type-mapping>mySQL</type-mapping> property vale present in mysql-ds.xml file is the same as the <type-mapping>              property in standardjbosscmp-jdbc.xml file. I am guessing, i am missing some configuration which is causing the issue. Could someone educate me on what needs to be updated to fix this issue. I see a few people have the same issue, but was not able to find a concrete solution or a pointer to the root cause of the issue.
