OGNL validation question
Is there a way to check if a String is valid OGNL?
Continuing work on my custom parser. right now it performs the Perl
expression checks for
things like property names. Also, it can try to resolve fully qualified
classnames for class attributes in tags like component-specification and
service.
Wouldn't be hard to add OGNL checks if the its framework has an API for
that.

Hi Geoff,
The ongl class has a parseExpression class that takes the string
expression and either returns an "abstract syntax tree" or throws
"ExpressionSyntaxException". It also has a bunch of static methods you can
use after you get the tree like "isSimpleProperty",
"isSimpleNavagationchain" etc.
Take care,
John
