Working classes with JSP

Expand Post »

Hi everyone,

I am trying to use classes with JSP but I have a problem. I created a class and a method that will be used to return a specific querystring value . But I get an error while compiling the class and I can't solve the problem.

I use Apache Tomcat & J2SE on Windows XP Pro. SP2.

The class I wrote :

JSP Syntax (Toggle Plain Text)
public class pageIdentification
{
    private String process;
 
    public pageIdentification(){}
 
    public String deneme (){
        process = request.getParameter("process");
        return (process);
    }
 
}
public class pageIdentification
{
    private String process;

    public pageIdentification(){}

    public String deneme (){
        process = request.getParameter("process");
        return (process);
    }

}

and the error I get :

JSP Syntax (Toggle Plain Text)
>javac pageIdentification.java
pageIdentification.java:8: cannot find symbol
symbol  : variable request
location: class pageIdentification
                process = request.getParameter("process");
                          ^
1 error
>javac pageIdentification.java
pageIdentification.java:8: cannot find symbol
symbol  : variable request
location: class pageIdentification
                process = request.getParameter("process");
                          ^
1 error

Could anyone help me please?

Re: Working classes with JSP

The request object in a servlet is a passed in Object, not some sort of magical reference. You would have to rewrite this to either pass the request object into the called method or retrieve it from the ServletContext. But, in either case, you will also need to import a couple of further classes from the J2EE packages.
