Tras estar investigando, y en vista que nadie pudo ayudarme, he logrado mi conexion.
para poder hacer uso cree un .java en el cual hice varias funciones, pero la principal es esta:
public Connection getConexion()
{
try
{
Context cont= new InitialContext();//se crea el contexto
ds = (DataSource)cont.lookup("jdbc/myDatasource"); // se agrega el jdni del datasource
con=ds.getConnection();//obtengo la conexion
return con;
}
catch(SQLException sqle)
{
return null;
}
catch(NamingException ne)
{
return null;
}
}
y el xml (que ya te lo genera el netbeans por cierto lleva esto:
<resources>
<jdbc-resource enabled="true" jndi-name="jdbc/myDatasource" object-type="user" pool-name="mysqlPool">
<description/>
</jdbc-resource>
<jdbc-connection-pool allow-non-component-callers="false" associate-with-thread="false" connection-creation-retry-attempts="0" connection-creation-retry-interval-in-seconds="10" connection-leak-reclaim="false" connection-leak-timeout-in-seconds="0" connection-validation-method="auto-commit" datasource-classname="com.mysql.jdbc.jdbc2.optional.MysqlData Source" fail-all-connections="false" idle-timeout-in-seconds="300" is-connection-validation-required="false" is-isolation-level-guaranteed="true" lazy-connection-association="false" lazy-connection-enlistment="false" match-connections="false" max-connection-usage-count="0" max-pool-size="32" max-wait-time-in-millis="60000" name="mysqlPool" non-transactional-connections="false" pool-resize-quantity="2" res-type="javax.sql.DataSource" statement-timeout-in-seconds="-1" steady-pool-size="8" validate-atmost-once-period-in-seconds="0" wrap-jdbc-objects="false">

<property name="URL" value="jdbc:mysql://localhost:3306/enviosms"/>
<property name="User" value="root"/>
<property name="Password" value="123"/>
</jdbc-connection-pool>
</resources>
