jsp method declarations

Is there a way of  using jsp custom tag in a jsp declaration such as:

<%!
public void pumpOutChildren(IItem currentItem)
{       
%>
<ms:bindings name="currentItem" id="boundItem">
<%=  
   boundItem.getFullName();
%>
</ms:bindings>
<%
}
%>

as this does not appear to work

I don't think so, as the <ms:bindings bit is outside the <%! bit, and therefore it is invalid in the generated servlet :-(

<%!
public void pumpOutChildren(IItem currentItem)
{      
%>

opens a new method in the generated Servlet, but it has no closing tags...so the JSP won't compile :-(

I hope you see what I mean...

The answer to your question is NO!
because :
The tag needs other environment support that you don't have it in your declared method.
And you cannot mix <%! with <%.

Most of jsp processor will extract all <%! and process first, then the rest.

Hmmmm...

You can do:

<%!
public void pumpOutChildren( IItem currentItem )
{      
    out.println( currentItem.getFullName ) ;
}
%>

Not sure that "out" will be valid though...  you might need to do:

<%!
public void pumpOutChildren( IItem currentItem, PrintWriter out )
{      
    out.println( currentItem.getFullName ) ;
}
%>

Then you can call the method from your JSP code:

<%
  pumpOutChildren( item ) ;
%>

or

<%
  pumpOutChildren( item, out ) ;
%>

NO, not custom tag in a jsp declaration.

But you might be able to something similar with <jsp:include>
you put you custom tag in an included jsp page, and in the main page use <jsp:include> when you need to call it.
