Connect JBOSS to MySQL using datasource,both servers are on different machi

Question

HI,
In my application, I use JBOSS server and MySQL database.JBOSS and MySQL server are on two different machines.I am using mysql datasource,not driver manager to get the connection. i configured mysql-ds.xml and put it in %JBOSS_HOME%\server\default\deploy directory.
I have also put the mysql connector jar in the %JBOSS_HOME%\server\default\lib directory.
mysql-ds.xml file
<?xml version="1.0" encoding="UTF-8"?>
<!-- $Id: mysql-ds.xml 41016 2006-02-07 14:23:00Z acoliver $ -->
<!-- Datasource config for MySQL using 3.0.9 available from:
http://www.mysql.com/downloads/api-jdbc-stable.html
-->
<datasources>
<local-tx-datasource>
<jndi-name>JBossAtWorkDS</jndi-name>
<connection-url>jdbc:mysql://192.168.1.3:3306/JBossAtWorkDS</connection-url>

<!-- should only be used on drivers after 3.22.1 with "ping" support
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-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 - MySQLValidConnectionChecker is preferred for newer drivers

-->
<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>
code to make the connection is as follows...
public class JDBCCarDAO implements CarDAO
private List carList;
private static final String DATA_SOURCE="java:comp/env/jdbc/JBossAtWorkDS";
public JDBCCarDAO()
public List findAll()
List carList = new ArrayList();
DataSource dataSource = null;
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try
dataSource = ServiceLocator.getDataSource(DATA_SOURCE);
conn = dataSource.getConnection();
stmt = conn.createStatement();
stmt.execute("select * from CAR");
     rs = stmt.getResultSet();
while(rs.next())
CarDTO car = new CarDTO();
car.setMake(rs.getString("MAKE"));
car.setModel(rs.getString("MODEL"));
car.setModelYear(rs.getString("MODEL_YEAR"));
carList.add(car);
catch (Exception e)
System.out.println("No SQL connection is made"+e);
finally
try
if(rs != null){rs.close();}
if(stmt != null){stmt.close();}
if(conn != null){conn.close();}
catch(Exception e)
System.out.println(e);
return carList;
I am getting an error as follows...
No SQL connection is made.
org.Jboss.util.NestedSQLException:Could not create connection; -nested throwable: (java.sql.SQLException:Unable to connect to any host due to exception:java.net.ConnectException:Connection Time out:connect......
how to get rid of this problem????plz...someone help me....

If you have access to a copy of TimesTen 6.0 you can look in the AppServer Configuration Guide (appsrv.pdf) that was shipped with that release. This guide is currently being rewritten and so is not yet available for 7.0.
If you can't get hold of a copy, e-mail me at [email protected] and I'll send it to you.
