The xml files are exactly the same. I used the 'beyond compare' file
comparison utility to view this, and there are no differences. .
What next?
This error occurs when the configuration for a vaidation method
doesn't match up with the actual method signature. So in your case the
FieldChecks's validateRequired() method has a different method
signature from what is configured in the methodParams element for the
required validator in validator-rules.xml. As I said before, typically
this occurs when people ugrade to a newer version of Struts and forget
to upgrade the validation-rules.xml - but whatever the cause the
solution is the same - ensure you have the correct
validation-rules.xml for the version of Struts you're using.
Saying "My IDE is 'MyEclipse' which uses a Struts 1.2 release." is
vague - you need to determine which 1.2 version of Struts that is
(There are four "GA" quality releases of Struts 1.2 - they are 1.2.4,
1.2.7, 1.2.8 and 1.2.9). The MANIFEST.MF file in the struts jar should
tell you what version of struts you're using - when you find that out
download that version of Struts and grab the validator-rules.xml from
it.
