Can you tell me the difference of these output streams in Jsp?

[Alexander Sales]

whats the difference in using these different tags or scriptlets when printing Strings in jsp?
ex: String helloWorld = "Hello World";

<%= helloWorld; %> or <% out.println(helloWorld); %>
${helloWorld}
<c:out value="${helloWorld}"></c:out>

Difference(or the rule you MUST remember) is that you should not use scriptlets or scriptlet expressions in JSPs at all. Use EL with JSTL instead (as you've done).

Is it really prohibited to use scriptlets? aren't there any times that we have no other choice but to use a scriptlet?

Scriptlets are never necessary, and should never be used in modern JSPs. They have been discredited for almost 10 years now and using them is simply irresponsible at this point.

If there's something that you are doing in your JSP that cannot be done with modern techniques, it's a huge red flag that you are trying to do something that should not be done in a JSP at all, but likely in the page controller.

thanks sir bear, but it is a 'nice to have' in SCWCD right?

[Bear Bibeault]

The SCWCD is not the real world.
