about OGNL

[Pradeep Adibatla]

I have started using OGNL in my struts-2 application and I have been asked to clarify why it is used...

I need to know about the memory consumption in using OGNL...

what else are it's advantages??

JSTL-EL,velocity,groovy are the others i know ...

[David Newton]

OGNL is substantially more powerful than JSP EL (look at the OGNL user guide). It's also pretty slow.

I'm not sure what the current status is, but there was some talk about allowing the use of MVEL (fast) and the JSP EL implementation might even already be in--I've been out of the loop for a few months.

Are there any memory leaks in this ?? any in struts-2 as such ,some instances?

I want a look at some of the factors...please direct me to user guide! Any other inputs would be great help

[David Newton]

What other factors? What are you trying to learn?

[Pradeep Adibatla]

I mean are there any memory leaks with this? what do we mean by powerful? in what ways?

[David Newton]

Look at the OGNL documentation, then compare it to JSP EL. I have no idea if there are any memory leaks, if there are, they're not significant.
