RE: OGNL expression help
> Extending String? String is final so it isn't doable ;-) I did not check that. I see someone posted a better solution than this but I guess if someone wanted to have a getLength() for a String, they could write a container class that holds a String and then implement all the methods to call the corresponding String methods. That would be really be a pain! Anyway, thanks for the clarification, Neil -- Neil Aggarwal, (281)846-8957, http://UnmeteredVPS.net Host your struts app on a CentOS VPS for only $25/month!

Re: OGNL expression help
Like Neil suggested, use "attrib.length()" The extra parens cause OGNL to
call getAttrib().length() rather than getAttrib().getLength().

You could create your own MyString class that
extends String and then have a getLength() method
that calls super.length().
It's a pain, but should work.

LOL :) I suspect that my difficulties in trying to use OGNL to insert the
length are related to the fact that the method call on a string is
String.length() not String.getLength and when I use size="%{attrib.length}"
OGNL is trying to call getAttrib().getLength() on my action -which won't
work.
So, rephrasing slighly, how do I/can I use OGNL to call methods on
attributes in my actions that do not follow the Bean pattern.

Also, what if the myString is null or an empty string. The code would throw a null pointer or the field size would be zero.
