[Folashade Adeyosoye]

How can I turn off the Database connection pool in the dao.xml        <transactionManager type="JDBC">       <property name="DataSource" value="SIMPLE"/>       <property name="JDBC.Driver" value="${driver}"/>       <property name="JDBC.ConnectionURL" value="${url}"/>       <property name="JDBC.Username" value="${username}"/>       <property name="JDBC.Password" value="${password}"/>       <property name="JDBC.DefaultAutoCommit" value="true"/>       <property name="Pool.MaximumActiveConnections" value="10"/>       <property name="Pool.MaximumIdleConnections" value="5"/>       <property name="Pool.MaximumCheckoutTime" value="120000"/>     </transactionManager>       I tried changing the       <property name="Pool.MaximumActiveConnections" value="0"/> and   <property name="Pool.MaximumIdleConnections" value="0"/>, but I got an exception     exception is thrown - java.lang.IndexOutOfBoundsException: Index: 0, Size: 0     Thanks
