Is it possible to capture selected values on jsp page?
Hi,
I have two drop down lists. Once a user selects once
item for every list, she will press on submit button.
The two lists are collections. I am trying to capture
these two values after the user submission. Is there
an easy way to do that?
regards,

Thanks, very helpful...
Still one thing unclear: do I need to put my action
form
in classpath to be imported in my jsp page? Is there a
better way to do it? This sounds messy, but I will try
it out if it works.

Well, ultimately jsp IS Java.... You can always do
this:
<%
String
foo="http://myweb.com/mypage?companyid="+id+"&ssn="+ssn;
%>
<mytag:sample name="persons" uri="<%=foo%>" />
However, use of scriptlet is discouraged here. If you
switch to JSTL tags, and put foo into an ActionForm
property populated in your Action, you could:
<JSTLtag:sample name="persons" uri="${myForm.foo}" />

Thanks,
I will try that out. What I try to do is to capture
form variables as strings, and concatenate them with
a html address as request parameters. I am not sure
how to
concatenate them with the link in JSP page, and add
the
whole address to a taglib parameter like the
following:
<mytag:sample name="persons"
uri="http://myweb.com/mypage?companyid="+id+"&ssn="+ssn>
In Java, we can concatenate strings like that, in Jsp,
can we do that? Or there is another way?
regards,

Well, I don't use that taglib, so I'm not sure. In
your situation, I believe the ActionForm is available
to you, even outside the <html:form> tags. When the
<html:form> code executes, it creates an ActionForm
instance, iff one does not exist (see
http://jakarta.apache.org/struts/struts-html.html#form).
However, in your case, the ActionForm you want access
to was created and populated when processing the
request. I don't know what you wanted to do with the
selection, but it should be available using
name="myForm" and property="theSelection" in most
Struts tags. You might need to include logic not to
use them, when the ActionForm has not yet been
created.

Thanks, Michael:
I actually want to capture them outside
<html:form>...<.html:form>. I know these values
will be in my action form, should I use <jsp:usebean>
to
get their string values?

So long as both <select>s are in the same <form> as
the <input type="submit">, they will both be in the
request.
