Testing environment: netbeans7.11 + glassfish 3.11
here is the jsp, class code:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<jsp:useBean id="gb" class="GameBean" scope="session" />
<jsp:setProperty name="gb" property="operation" value="OOOOOOOOO" />
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1><jsp:getProperty name="gb" property="operation" /></h1>
    </body>
</html>



public class GameBean {
    private String operation; //operation

    public void setOperation (String operation) {
        this.operation = operation;
    }

    public String getOperation () {
       return this.operation;
    }

}


Error message: org.apache.jasper.JasperException: PWC6054: Cannot find any information  on property 'operation' in a bean of type 'GameBean'
C:\Users\ray\Desktop\OU\COMPS311\tma02\web\nbproject\build-impl.xml:612: Java returned: 1 BUILD FAILED (total time: 1 second)

    Make your getOperation() and setOperation(...) methods public.

    After your updates the new issue seems to be that your GameBean is defined in some package which you are not importing (or using the fully qualified name) in JSP.
