The method signature in the FieldChecks class doesn't match what you
have specified in the validator-rules.xml config file.
Usually this happens when you upgrade to a later version of Struts,
but don't upgrade the validator-rules.xml file - make sure you upgrade
to the validator-rules.xml thats shipped with the version of Struts
you're using.

Subject: Re: Commons validator
When your struts application starts up it parses the validation xml
files you specify for Struts's validator plugin and creates the
configuration objects needed by Commons Validator and stores them in
application scope. These are the "resources" its referring to.
When your ActionForm's validate method is called it tries to retrieve
those "resources" from application scope to get the configured
validation rules to use for the form.
If it can't find the "resources" then it looks like something has gone
wrong at startup - first place to check the configuration you have in
struts for validator - and the logs to see if there are any
errors/warnings at startup time.
You'll probably get more help asking Struts related questions for
validator on the Struts user list.

However, I must not have set it up properly. After going through the setup I am
