Hello Luis,
I think I may have a very similar problem to yours. Have you found a way to solve it?
I use Netbeans
IDE v7.1 + Struts 2/XWork plugin with Struts 2.2.3 Libraries
Netbeans Plugin page
I have also tried to integrate Struts2-Jquery plugin from here:
http://code.google.com/p/struts2-jquery/wiki/DatePickerTag
The file I downloaded was named: struts2-jquery-plugin-3.3.0.jar
First of all, I added it to the project as JAR/Folder Library.
Next, I copied the example code in a JSP page, with the following structure:
The start page as configured in web.xml is of course
calendars/calendarDemo.jsp
Netbeans doesn't detect any errors, as the Datepicker tag is correctly detected and checked.
On the other hand, after getting deployed it gives only an Error 500 Page with the following notice:
Is there anything I am missing to configure this plugin? ANY HELP WILL BE MUCH APPRECIATED !
I paste here the complete error log:
