The method of setting up MySQL data source under Jboss4.0

How to use MySQL's data source in JBOSS4:

A MySQL-driven JDBC driver is placed in the classpath. Again, copy it to the/server/default/lib directory.

Two copies of the/docs/examples/jca/mysql-ds.xml to the/server/default/deploy directory. Modify Mysql-ds.xml file, set <driver-class/> to Com.mysql.jdbc.Driver <connection-url/> set to jdbc:mysql://< Mysqlhost>/<database>, where <mysqlhost> is the database host name <database> is the database name.

Three to replace the Docexamplesdocsexamplesjmsmysql-jdbc2-service D:javaonejboss4.0serverdefaultdeployjmshsqldb-jdbc2-service

Four then you need to set the <datasource> and <type-mapping> elements of the Defaultconfstandardjaws.xml file:

<jaws>
<datasource>java:/MySqlDS</datasource>
<type-mapping>mySql</type-mapping>
</jaws>

It is also necessary to set the <datasource> and <datasource-mapping> elements of the Standardjbosscmp-jdbc.xml file to the following:

<jbosscmp-jdbc>
<defaults>
<datasource>java:/MySqlDS</datasource>
<datasource-mapping>mySql</datasource-mapping>
</defaults>
</jbosscmp-jdbc>

Five more to modify the Login-config.xml file to use MySQL:

<application-policy name = "MySqlDbRealm">
<authentication>
<login-module code =
"org.jboss.resource.security.ConfiguredIdentityLoginModule"
flag = "required">
<module-option name ="principal">sa</module-option>
<module-option name ="userName">sa</module-option>
<module-option name ="password"></module-option>
<module-option name ="managedConnectionFactoryName">
jboss.jca:service=LocalTxCM,name=MySqlDS
</module-option>
</login-module>
</authentication>
</application-policy>

Six Serverdefaultdeployejb-deployer.xml in the file

create table TIMERS (
　　　　　 TIMERID varchar(50) not null,
　　　　　 TARGETID varchar(50) not null,
　　　　　 INITIALDATE timestamp not null,
　　　　　 INTERVAL bigint,
　　　　　 INSTANCEPK other,
　　　　　 INFO other,
　　　　　 constraint timers_pk primary key (TIMERID)

Change other type to Bolb type

After this configuration, the default data source for JBoss is changed to MySQL.
