JSP Declaration

The JSP declaration scripting begin with <%! and end with %>. Variables declared in JSP declaration may be used in expressions orscriptlets.

The XMP syntax for declaration is <jsp:declaration>…</jsp:declaration>

The example below illustrates a few variants of JSP declarations.


<%! int i; %>
<%! String str=”hello world”; int y=0; %>
<%! boolean flag=true; %>
<%! Boolean flagClass=new Boolean(true); %>

All examples above declare variables. They do not print any thing on the web page. A scriptlet or an expression can be used to access variables declared in JSP expression.

Similar to variable declaration, method declaration may also be included within JSP declarations.
