Hello All,
In page 447 of Head First
Servlets and
JSP, the authors have mentioned that default scope for <c:set> is page scope. Further, in the section "there are no dumb questions" , the authors have mentioned in the second answer that if you do not use scope in the tag, the container will search scope in the following order - page, request, session and then application/context. Only after not finding an attibute in any of the four scopes, the container will create a new attribute in the page(default) scope.
Ok, after that in a
thread I looked up to clear my understanding(
http://www.coderanch.com/forums/), Kathy has said that the container will look ONLY in the page scope. If it does not find an attribute, in the page scope only, then it will create a new attribute.
So, if i have
request.setAttribute("name", "abc")
and use
<c:set var="name" value="def"/>
and use
${pageScope.name}
Assuming, these are the only attributes,Will I get null(the container searched through all the scopes) or "def" (the container looks in page scope only and creates a new attribute in page scope finding no attribute matching name in page scope).
I am a little confused. Where am I going wrong?
Thanks in advance.
