Examples with ValidationMessage javax.servlet.jsp.tagext.ValidationMessage used on opensource projects

Example 1 with ValidationMessage

use of javax.servlet.jsp.tagext.ValidationMessage in project sling by apache.

the class Validator method validateXmlView.

// *********************************************************************
// Private (utility) methods
/**
     * Validate XML view against the TagLibraryValidator classes of all imported
     * tag libraries.
