I am trying to port a sturts 1.0 app from weblogic to jboss 4.2.2. when loading the first page of the app I get the following error:

The line causing the problem looks like this:
<html:submit styleClass="normalButton" styleId="save" property="action" value="Save" onClick="return validateAllForCust(document.customerForm)"/>

Thanks for any help.
