Welcome to the Ranch James.

but a recive an error( i'm using out.println)...how can i do that?


You can begin by giving us more information. What is the line of code that is causing the error, and what is the exact wording and nature of the error.
Otherwise, it's just guesswork.

Post your code. Post your error. Then maybe someone might be able to spot what's wrong.

Try passing the response object to the class and then do response.getWriter().
This should give you a printwriter reference. You can use this to write to the web page.
To be more precise, you have to post your code.

You can call a method such as this from your JSP:

On your JSP page, you would have something like:

I am not sure whether i've understood ur question correctly but leme try .
1) make a class wth a function . e.g:
public class test
{
public String getStr()
{
String str = new String();
str = "JAMES";
return str;
}
}
2) call this class in the jsp and using the class object, call this function. E.g :
Test t = new Test();
String str = t.getStr();
out.println(str);
3) run the jsp file and see the output . If it doesn't print "JAMES" then there is something wrong in your calling the class file.
Hope this helps
