FomatDateTag in JSTL not working

[cboyd]

I'm getting the following exception when trying to use the <fmt:formatDate/> tag included in the JSTL version 1.0.3 in my JSP:

tartDate}"; - nested throwable: (java.text.ParseException: Unparseable date: "${

Here is the tag as it appears in my JSP:

<fmt:formatDate dateStyle="short" pattern="MM/dd/yyyy" value="${policy.startDate}"/>

It doesn't even appear to be calling the FormatDateTag, but the DateEditor class instead. The ${policy.startDate} is a property in a JavaBean that is of type java.util.Date. Has anyone had any luck using this tag in their JSP under JBOSS 3.0.8/Jetty bundle? I've had luck getting other JSTL tags to work, just not this one.

Thanks.

A very simple neural network can learn load statistics
(in basic - which node is faster) and therefore it would be able to balance tasks more optimal than RoundRobin or Random policy.

I am working on it, and I am sure it'll work.

For example, if I have two nodes in cluster, where one is two times faster than other then RoundRobin isn't the best, is it.

However there are some minor practical problems, for instance, neural net will have to maintain the information it has learned (weights of neuron connections) somehow

so... practical meaning of it may not be very big.
But still interesting research topic.

BTW I have read that next version of WS is going to have
some kind of dynamic load balancing "based on server statistics".

I'll post my results in this forum.
