Ranchers,

Om page 362 of the HFSJ book, the line says <jsp:setProperty name="person" property="empID" value="<%=request.getParameter("empID")%>" Why does this fail to compile when the empID is of type int?? I'm not understanding?

the automatic type conversion will not happen for jsp expression while el expression will do the type conversion. thatz why it will give a compilation error.

Vijayakumar,

How does the EL does the implicit type conversion?? Is there any rule or is it according to the spec?

Jothi,

Just remember this. Auto-Type_Conversion WILL NOT happen in jsp:setProperty, if we use scripting in 'value' attribute.

To get rid of this problem, use EL or string literal.
