Hi,
Here's what I want to achieve :
I have a form (call it INPUT). Let's say the form's action is "ActionA.do".
ActionA.do is mapped to com.mycompany.myclass, which can either forward to
"success" or "failure". In struts-config.xml, "success" is mapped to
"ActionB.do", and I want "failure" to be mapped to a simple JSP error page,
call it "failure.jsp". In other words, I don't want to re-display INPUT
with errors (<html:errors>) : I want a completely different page, because it
doesn't make sense in my application to re-display the INPUT form when this
error occurs.
In failure.jsp, I want to display the error message, and have a button that,
when clicked, will return the user to some other page, mapped to
"ActionStart.do".
So, I thought I would use the following struts tag : <html:form
action="ActionStart.do"> in that error page.
When I try the application, and the failure condition is triggered, I get
the following error message :
2004-12-03 13:27:20 StandardWrapperValve[action]: Servlet.service() for
servlet action threw exception
org.apache.jasper.JasperException: Cannot retrieve definition for form bean

org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:2

at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
...
My "fix" for this error was to forget about the struts <html:form...> tag,
and just use HTML's <form...> instead.
Although this worked, I would love to have an explanation as to why I got
the error mentionned, and maybe some workaround that would let me use
<html:form>...
