I just want to know if I put three attribute with the the name "attr" respectively in the request, session, servletcontext, how can I output all of them using EL in the JSP.

Hi

While you have got the answer for your second question, let me answer your first question.

${attribute1} uses findAttribute() by default. Thus it first searches for a variable named 'attribute1' in page scope, followed by request, session and application scopes.

That is why values get printed in that manner.
