OK have a look:

JSP code:

<%  if(thisCodeIsOK){ %>

I am a genius !

<% }%>

<% else { %>

JSP parser is genius !

<% } %>

Tell me are you a genius?

I don’t think so. To be genius you have to write this code as following

<%  if(thisCodeIsOK){ %>

I am a genius !

<% }else { %>

JSP parser is genius !

<% } %>
