BTW, the only reason I strated using the "-" minus sign in my JSP URL variable
is to follow the
convention used by Struts Annotation that uses "-" sign to map to the
corresponding Action class
name.
For example, if the actions are in a package "com.softlagos.web.struts2.action";
And I have a class called
"com.softlagos.web.struts2.action.ViewRegister.class", then,
the action name "view-register" maps to the ViewRegister class.
Therefore, the Struts 2 Annotation is using the "-" minus to map action names
to action classes.
And since my URLs map to actions, I therefore named the variables the same way.
That is,
with the "-" minus sign in it. However, I did not know that I would have
problems with OGNL in the
<s:a href="..." />. Now, that I know OGNL does not work with "-" minus sign, I
am renaming all
my variables to use the "camel" notation which is what I use throughout all my
Java code anyway.
Thanks,
Rubens.

I prefer camel case anyway for my variable names but if you like the
hyphen, I think you could do something like this:
%{#application['viewRegister']}

That fixed the problem.
The following works:
<s:a href="%{#application.viewRegister}"
title="%{getText('textTitle.account.register')}">
<s:text name="link.account.register" /></s:a>
Bottom-line: We *cannot* use "-" (minus-sign) when naming variables that
are used by the OGNL parser. Like in the case of the <s:a href="..."
/>.
Thank you very much.
Rubens.

It seems to me that the minus sign in your expression might be being
confused by the OGNL parser. You might try renaming your variable to
something that is consistent with the Java bean naming convention and
stay away from arithmetic operands.
Maybe change
<s:a href="%{#application.view-register}"
title="%{getText('textTitle.account.register')}">
to
<s:a href="%{#application.viewRegister}"
title="%{getText('textTitle.account.register')}">
