Hi,
My problem is solved. I followed the steps mentioned below

1.Replace jboss-4.0.0/server/standard/deploy/hsqldb-ds.xml by a file named mysql-ds.xml with the following content:
<datasources>
<local-tx-datasource>
<jndi-name>DefaultDS</jndi-name>
<connection-url>jdbc:mysql://localhost/test</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>jboss</user-name>
<security-domain>MySqlDbRealm</security-domain>
</local-tx-datasource>
</datasources>
2.Edit jboss-4.0.0/server/standard/conf/standardjaws.xml with the following parameters:
<datasource>java:/DefaultDS</datasource>
<type-mapping>mySQL</type-mapping>

3.Edit jboss-4.0.0/server/standard/conf/standardjbosscmp-jdbc.xml with the following parameters:
<datasource-mapping>mySQL</datasource-mapping>
…
<fk-constraint>true</fk-constraint>

4.Replace file jboss-4.0.0/server/standard/deploy/jms/hsql-jdbc2-service.xml by file jboss-4.0.0/docs/examples/jms/mysql-jdbc2-service.xml and change MySqlDs to DefaultDS (line 47) in that file.
