I have JSP that works fine in Tomcat 7 but does not work in Tomcat 6 which I assume is the fact that you cannot call methods (other than getters/setter) from EL 2.1.
The method I need to call cannot be named as a getter.
I figured out a workaround and thought I would post the answer:
If you have Spring installed you can use Spring EL so that you can call methods on objects
For example:
<spring:eval expression="pic.thumbnailUrl()" var="thumbnail" />
