Examples of org.apache.catalina.deploy.WebXml

org.apache.catalina.deploy.WebXml
Representation of common elements of web.xml and web-fragment.xml. Provides a repository for parsed data before the elements are merged. Validation is spread between multiple classes: The digester checks for structural correctness (eg single login-config) This class checks for invalid duplicates (eg filter/servlet names) StandardContext will check validity of values (eg URL formats etc)
