struts form bean

[Daniel Wang]

How do I access the form bean in struts?

For example, the bean called formBean has a method called isError(String
param).

Suppose the user enters information in Form.jsp and gets redirected to the
action, and then because he missed some required fields, is sent back to
Form.jsp. How would I get the formBean, and how would I call the above
method?




Thanks.

From your JSP page you use the Struts HTML tags. Look here:
http://jakarta.apache.org/struts/userGuide/struts-html.html

If you need to make a decision based on the isError property, you can
query it with the Struts Logic tags:
http://jakarta.apache.org/struts/userGuide/struts-logic.html

But it's often easier to query bean properties and make decisions by
using the JSTL tags:
