package canyin;

import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;

public class checkSessionBean
{

private boolean bolCheckPass=false;
private HttpServletRequest request = null;

public boolean checkSessionBean(HttpServletRequest request,String strSessionName,String strCheckValue)
{
public boolean checkSessionBean(HttpServletRequest request)
{
HttpSession session = request.getSession(false);
return(bolCheckPass);

if (strSessionName==null || strCheckValue==null)
{
return(bolCheckPass);
}
else
{
if (session!=null && session.getValue(strSessionName)!=null)
{
bolCheckPass=session.getValue(strSessionName).equals(strCheckValue);
}

return(bolCheckPass);
}
}
}
}
编译时总出现错误，请大家指正，多谢!
