Request.getParameter("blah") from within a class?

Question

Hi Everyone,
Not sure if I'm missing something...
I'm trying to create a class that will examine and parse information from a form, and then pass it to another class that knows how to handle the input.
A request in the form of http://www.domain.com/stuff.jsp?1=param1&2=param2&4=param4
stuff.jsp only has this:
UrlRequestGetter params = new UrlRequestGetter();
out.println(params.getTheParams());and the general idea for the UrlRequestGetter class is this:
public classUrlRequestGetter {
     public String getTheParams(){
          String request1 = request.getParameter("1");
                String request2 = request.getParameter("2");
                String request3 = request.getParameter("3");
                String request4 = request.getParameter("4");
}Within that class, there will be various actions to check whether or not fields are empty, etc. The big point is that i'm trying to do a request.getparameter from within a class. When i try to compile, I get:
cannot find symbol
symbol:variable request
Any thoughts?
Thanks!

Answer 1

Take a step back from all that, and read the error message: cannot find symbol: symbol:variable request
Is "request" a variable you have declared or passed into your method getTheParams() ?
Where is it supposed to get the request from?
"request" is an implicit variable to your JSP. If you want to use it in your bean, you have to pass it as a parameter.
I'm trying to create a class that will examine and parse information from a form, and then pass it to another class that knows how to handle the input.You might consider using the <jsp:setProperty> tag to map parameters to bean attributes automagically.
Or the BeanUtils.populate method provided by Jakarta Commons BeanUtils.
Or any framework like struts, jsf, spring, stripes....
