我這里的配置分為以下幾步：
第一步：從jboss-4.0.2\docs\examples\jca目錄下的mysql-ds.xml復(fù)制文件到D:\jboss-4.0.2\server\default\deploy目錄下并編輯如下：
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/test</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>
<password>root</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
<!-- sql to call when connection is created
<new-connection-sql>some arbitrary sql</new-connection-sql>
-->
<!-- sql to call on an existing pooled connection when it is obtained from pool
<check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
-->
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>
第二步：編輯jboss-4.0.2\server\default\conf下的三個(gè)文件：standardjbosscmp-jdbc.xml，standardjaws.xml，login-config.xml
standardjbosscmp-jdbc.xml修改部分：
<datasource>java:/MySqltDS</datasource>
<datasource-mapping>mySQL</datasource-mapping>
standardjaws.xml修改部分：
<datasource>java:/MySqltDS</datasource>
<type-mapping>mySQL</type-mapping>
login-config.xml修改部分：（可以添加這一段，復(fù)制一段進(jìn)行修改）
<application-policy name = "MySqlDbRealm">
<authentication>
<login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule"
flag = "required">
<module-option name = "principal">test</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>
</authentication>
</application-policy>
第三步：重啟jboss沒(méi)有出現(xiàn)異常，就會(huì)有如下顯示，證明配置正確：
第四步：如果你還步放心，現(xiàn)在寫(xiě)個(gè)servlet試試吧：
response.setContentType("text/html;charset=gb2312");
PrintWriter out = response.getWriter();
try {
// Put your code here
Context cx = new InitialContext();
Object obj = cx.lookup("java:/MySqlDS");
DataSource ds = (DataSource)obj;
Connection connect = ds.getConnection();
Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery("select * from customers");
while(rs.next()){
out.println(rs.getString("name"));
}
} catch (NamingException e) {
e.printStackTrace();
} catch(SQLException e1){
e1.printStackTrace();
}
out.flush();
out.close();
