grails Basics


Example

GSP supports the usage of <% %> scriptlet blocks to embed Groovy code (this is discouraged):

<html>
   <body>
     <% out << "Hello GSP!" %>
   </body>
</html>

You can also use the <%= %> syntax to output values, like in JSP:

<html>
   <body>
     <%="Hello GSP!" %>
   </body>
</html>

GSP also supports JSP-style server-side comments too:

<html>
   <body>
     <%-- This is my comment --%>
     <%="Hello GSP!" %>
   </body>
</html>
