Hi,
I am trying to change my the JDBC Persistence in JBoss 4.0.2 from the default hsqldb to
mysql.
For this it says that i need to deploy the relevant datasource. So i am tryin to change
the datasource from hsql to mysql.
The procedure which I followed for it is as follows:
1. To use JBoss 4.0 with MySQL, we first need to put the MySQL driver classes into the
CLASSPATH.
2. Copy the .jar file mysql-connector-java-3.0.9-stable-bin.jar to the
/server/default/lib directory.
3. To use the MySQL data source, copy /docs/examples/jca/mysql-ds.xml to the
/server/default/deploy directory.
4. Modify the mysql-ds.xml configuration file by setting <driver-class/> to
com.mysql.jdbc.Driver and <connection-url/> to jdbc:mysql:///, where is the MySQL
host server and is the MySQL database.
5. Next, we need to set the and <type-mapping> elements in the standardjaws.xml or
jaws.xml file: (standardjaws.xml or jaws.xml file, i can't find in JBoss 4.0.2)
java:/MySqlDS
<type-mapping>mySQL</type-mapping>
6. We also need to set the and <datasource-mapping> elements in the
standardjbosscmp-jdbc.xml or jbosscmp-jdbc.xml file:
<jbosscmp-jdbc>
java:/MySqlDS
<datasource-mapping>mySQL</datasource-mapping>
</jbosscmp-jdbc>
7. Finally, we modify login-config.xml with MySQL database settings. Add the following
<application-policy/> element to login-config.xml:
<application-policy name = "MySqlDbRealm">
<login-module code =
"org.jboss.resource.security.ConfiguredIdentityLoginModule"
flag = "required">
<module-option name ="principal">sa</module-option>
<module-option name ="userName">root</module-option>
<module-option name ="password">root</module-option>
<module-option name ="managedConnectionFactoryName">
jboss.jca:service=LocalTxCM,name=MySqlDS
</module-option>
</login-module>
</application-policy>
8.By modifying the mysql-ds.xml, standardjaws.xml(which i never got),
standardjbosscmp-jdbc.xml, and login-config.xml files, the JBoss 4.0 server is configured
to be used with a MySQL database.
I have removed the hsqldb-jdbc2-service.xml and hsqldb-jdbc-state-service.xml from
JBOSS_HOME\server\default\deploy\jmsn and replaced it with mysql-jdbc2-service.xml file.
Now the exceptions I am getting on running the server (dufault configuration) are:
08:59:09,281 INFO [ConnectionFactoryBindingService] Bound ConnectionManager
