if(strPassword.equals("boss"))
{
  <jsp:forward page="Welcome.jsp" flush="true"/>
}
else
{
  <jsp:forward page="Login.jsp" flush="true"/>
}
%>
```
Unmatched bracket in for statement
Flush attribute must be false
Keyword 'file' should be used instead of 'page' in the <jsp:forward/> action
Actions cannot be used within scriptlet blocks
What is wrong with the following code ?
```
<jsp:include page="MainMenu.jsp" flush="true"/>
<%
Cookie c = new Cookie("UserName", "Alastair Gulland");
response.addCookie(c);
%>
```
Cookie class can not take parameters in it's constructor
The request object is used for creating cookies
Although no error will be reported the use of the <jsp:include/> action means that the response object can't be used to create cookies.
The <jsp:include/> action must be placed inside the script block
