Jsp help
Hi,
I have an .html, and this .html has two checkboxes.,
<input type="checkbox" name="oop" value="circle" />
<input type="checkbox" name="oop" value="cilinder" />
and is "connected" to work with a .jsp.
<form action="2.jsp" method="post" >
What I want is that when i choose, for example the "circle" checkbox,
a result/output will be displayed in the 2.jsp.
But if I choose "cilinder" checkbox, another diferent result will be displayed in the 2.jsp.
How can I do this?
thanks for any response...

Which part of the coding don't you understand or can't you achieve? Please ask specific questions.
Firstnext step is to read the [url=http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/http/HttpServletRequest.html]HttpServletRequest API documentation[/url] and then especially the getParameterValues() method.
By the way, if you actually want single selections and not multiple selections, then use input type="radio" instead. As far I understand you likely want single selections.

Ok, look at this:
in .html:
<input type="checkbox" name="circle" />
in .jsp:
if(request.getParameter("circle").equals("on") )
{
<input name="name1" type="text">
<input type=submitvalue=Execute>
}
This obviously sends me an error, but is what I am trying to achieve:
If the checkbox is selected("on"), then, display a "text", and a submit Button.
how can I do that?

With scriptlet code, you need to embed the java stuff in <% %>, ant the html template text outside of it.
<%
if (request.getParameter("circle") != null){
%>
<input type="test" name="name1" >
<input type="submit" value="Execute">
<% } %>
With JSTL
<c:if test="${not empty param.circle}">
<input type="test" name="name1" >
<input type="submit" value="Execute">
</c:if>
