Not sure what the difference is, but I'm using the validationQuery property
to check the connection;
<property name="validationQuery" value=" select top 1 'niks' from DUAL "/>

The second thing I noticed is that 'select 1 from DUAL' will return all rows
in DUAL, shouldn't you use 'select top 1 * from DUAL'

hi

18/11/2009 03:18:49 ERROR Connection:19 - Error calling
Connection.setAutoCommit:
com.mysql.jdbc.CommunicationsException: Communications link failure due to
underlying exception:

** BEGIN NESTED EXCEPTION **

java.io.EOFException

STACKTRACE:

java.io.EOFException
       at com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1934)

my configuration file is:
<environments default="development">
                <environment id="development">
                        <transactionManager type="JDBC" />
                        <dataSource type="POOLED">
                                <property name="driver" value="${driver}" />
                                <property name="url" value="${url}" />
                                <property name="username"
value="${username}" />
                                <property name="password"
value="${password}" />
                                <property name="poolPingQuery" value="select
1 from DUAL" />
                                <property name="poolPingEnabled"
value="true" />
                        </dataSource>
                </environment>
