specific other language to JSP

JSP can specific other language to write script by use language attribute in page directive.

Is all language can use? Is any restriction? How does it compile to Servlet when it not java?

It's a vendor specific option really.


Just as m$ IIS app server can use vbscript, jscript, and now C# as scripting language. Certain Java application servers can use languages other than Java.

The JSP specification allows for JSP's to be made in other languages besides Java.


But it's up to the vendors to make engines that can run JSPs written in other languages. For example Resin allows you to make JavaScript JSPs.


I for one would love for someone to make an app server than can make JSPs in Python, Jython, and Perl.
