I have the standard validation working just fine. I have attempted to
branch out to use a custom validator for making sure that passwords follow a
certain set of rules. The custom validation method does not get called. I
set the logging to debug, but the output only confirmed that my method isn't
being called. Suggestions for how to debug further would be greatly
appreciated.
[log when standard validations fail]
DEBUG Date = 2003-05-27 12:22:54,543 [Thread-5]
org.apache.struts.action.RequestProcessor Line = 942 - Validation failed,
returning to '/gotochangepassword.do'
[log when standard validations pass - should call my validator]
DEBUG Date = 2003-05-27 12:19:14,939 [Thread-4]
org.apache.struts.action.RequestProcessor Line = 915 - No errors detected,
accepting input
Following are the relevant snippets of code:

Validation method
--------------------
public static boolean validateComplexPassword(

{

{

}
if (Character.isUpperCase(value.charAt(i)))
{

}
}
// verify that the new password has the requisite combination of
elements (1, A, a)
if (!(upperCase && lowerCase && digit))
{
errors.add(
field.getKey(),
Resources.getActionError(request, va, field));
return false;
}
return true;
