question from jsp spec

[Anonymous]

The next lines are all legal quotations.
• <%= "Joe said %/>" %>
but the above looks illegal..I think it should be....<%= "Joe said %\>" %>
please coorect me...

I have problems with nested stuff , like nested scripting, nested actions, ...
Could anyone tell me about the principle there?

[Madhav Lakkapragada]

For all such doubts, the best approach, IMO, is implementation.

Implementing for yourself is a good idea. It took me now 3 minutes to paste your code in a jsp of my test app in Tomcat -- start tomcat -- and search for generated code in the work-directory. So it might be time-saving for you too.
Here's the result. The <%= "Joe said %/>" %> is perfectly legal. The result in the generated java-file in the work-directory is:
out.print( "Joe said %/>" );
Why?
Because <%= "Joe said %/>" %> is like:
JspWriter out;
// lots of other code
//..
out.println ("Joe said %/>".toString());
This nested stuff is a very common feature in all flavours of web-development.
(With lotus-domino I have a technique where one has to write a lotus-formula-language which creates JavaScript and that generated JavaScript generates Html. Nice feature . But its no rocket science, if one time grasped the principles)

Beware though -- trying something out is no replacement for careful exegesis of the spec. In my experience many application servers have their idiosyncrasies. They either refuse a perfectly legal JSP, or they manage to digest the most horribly invalid markup.
