what if I add "encodeURL" to the action ?

[Artemesia Lakener]

I trid this --

<html:form action="<%= response.encodeURL("/submit") %>" >

what I get is --

The browser shows me "http 500 error", but once I hit "refresh" everything works. I was confused. So I click "internet option" / "advanced", and unmark "show friendly error msg". then I found there is unhandled exception from this line, so I change it to <html:form action="/submit" >
and then the HTTP 500 error disappeared.

Now, why did it always first show 500 error first but once I hit "refresh" everything worked since then ?

I don't know why the strange behavior, but I do know that you don't need to use the encodeURL method in any Struts tags. Struts automatically does encodeURL on all links.
