[Q]Unable to find a value for xx in object of class xxxx using operator .
Hi there,
I am using c:out to render values on a jsp.
c:out value=${local_object.url}/ works fine,
but when using
c:out value=${jar_object.url}/ I get the ServletException:
An error occurred while evaluating custom action attribute value with
value ${jar_object.url}: Unable to find a value for url in object of
class package.jar_object using operator .
I can get the value when using scriptlet on the same jsp
%
String url = jar_object.getUrl();
%
Does anyone know what I miss in the jar_object to make it avalaible for a
EL?
Thanks in advance,
Erica

Unable to make choose to work. need some help.
Hi All,
I'm a newbi to JSTL. I'm trying to compare a value while iterating through.
I get a value from the request object, while iterating I want to compare the
values with the value from the request object and if those two values are
equal I want to display the value.
something like this:
for(int i=0; i vec.size(); i++)
{
Object obj = (Object)vec.elementAt(i);
String name = obj.getFirstName()+ +obj.getLastName();
if(request.getParameter(reqName).equals(name))
{
DISPLAY THE FULL NAME
}
}
I tried to use the choose while otherWise in the c:forEach but
couldn't make it work.
Any code snippet would be very helpful.
Thanks in advance,
Aditya.

Custom tags outputting a JSTL tag
Hello,
I have a custom tag, and I want to output a JSTL tag on it.
But this new tag is not processed.
Like this :
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
out.println(c:out value=\y\/);
}
catch (IOException ex) {
}
return EVAL_BODY_INCLUDE;
}
Any help ?

This can't easily be done because the JSP container won't interpret your
output as tags. You could walk through the various steps that the JSP
container performs to invoke c:out -- e.g., instantiate a handler, call
the accessors, call doStartTag(), and so forth -- but that's
extraordinarily tedious.
An easier solution might be to use the RequestDispatcher to include a page
that contains the tag you want to include, parameterized by request
attributes. This leads to a better design anyway, where output stays the
responsibility of JSP pages.
