Diff. bet. JSP String ( %! String) and Java String.

Question

Hi all,
Think this is one of the basic Questions.
I want to know the basic diff. between <%!String a=10; %> and <%String a=10; %> programmatically,
with an example.

Answer 1

<%! ... %> are called jsp declarations, and are inserted into the generated servlet class.
<% ... %> are called jsp scriptlets, and are inserted into the _jspService method.
For example, the following jsp :
<%! String a = "10"; %>
<%!
  public void helloWorld() {
     System.out.println("Hello world");
%>
<% String b = "10"; %>Might be translated to the following servlet code :
String a = "10";
public void helloWorld() {
   System.out.println("Hello world");
public void _jspService(...) ... {
  String b = "10";
}
