How is JEXL used in JSP

How is JEXL used in JSP? I have encountered code like the following :

<v:set var='archive' value='jexl:archive.getArchives()' />
<v:set var='transaction' value='jexl:screen.getScreenObject("record",data)' />

But it does not make any sense to me. I understand that the code tries to retrieve archive and screen objects but how does the whole syntax work is still alien to me.

If some one can elaborate on the JEXL part!
