comparision in jsp

right now i m using

<% if (request.getAttribute("Error1") != null) { %>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp
<font color = "red"><%= request.getAttribute("Error1") %>
<% } %>

now i want to complare request.getAttribute("Error1") with a value 303,
which i got from setAttribute("Error1","303")).

i want, if(request.getAttribute("Error1") is equal to 303)

can anybody tell me the correct syntax for it in jsp.
