Well, here's how you'd do this with WebWork
(sourceforge.net/projects/webwork). First make a form JavaBean with the
field:
public class CourseForm
{
String course001 = "No";
public void setCourse001(String str)
{
course001 = str;
}
public String getCourse001()
{
return course001;
}
public Map getCourseTypes()
{
// You can of course put this in a separate
// JavaBean if you want to (recommended)
Map types = new HashMap();
types.put("No","No");
types.put("Basic","Basic");
types.put("Advanced","Advanced");
return types;
}
}
And in the JSP's form you'd do:
<webwork:include page="/template/standard/radiomap.jsp">
<webwork:param name="label" value="Course type:"/>
<webwork:param name="name" value="course001"/>
<webwork:param name="list" value="courseTypes"/>
<webwork:param name="key" value="key"/>
<webwork:param name="value" value="value"/>
</webwork:include>

Done. To customize this you can either change radiomap.jsp (which prints
out the radio button), or you can change a CSS stylesheet which is used
by the template JSP's (recommended).
WebWork also gives you per-field error messages that you can use. See
this example for more info:
Form JavaBean:
http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/webwork/src/main/webwork/test/FormTestForm.java?rev=1.2&content-type=text/x-cvsweb-markup&cvsroot=webwork
Validation of above form:
http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/webwork/src/main/webwork/test/FormTest.java?rev=1.3&content-type=text/x-cvsweb-markup&cvsroot=webwork
JSP used to view this form:
http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/webwork/src/resources/formtest.jsp?rev=1.6&content-type=text/x-cvsweb-markup&cvsroot=webwork
To run this example download the latest WebWork file release and deploy
webwork.war.
Hope this helps.
