Other than in your struts form tag, I don't see anyplace in your JSP where you would be trying to set a name property. I would start by going through stack traces in the logs to see if there is a line number in either the JSP or the generated servlet code where you can go for more hints.
Since this is a Struts project and since you aren't getting any help here, I'm going to move this to our Struts forum. [ July 17, 2007: Message edited by: Ben Souther ]
I believe NetBeans uses Struts 1.2.9. In this version of struts, the name and type attributes of the <html:form> tag are deprecated. Just remove them, and your page should work fine. They aren't really necessary anyway as you've already defined this information in your struts-config.xml file.
