Reports the following problems in descriptors that are used to deploy your Web Module to a server:

  • References to non-instantiable classes

  • References to classes that do not extend required class

  • References to classes with inappropriate scope

  • Empty tag and attribute values

  • Tag and attribute values that do not match required pattern (for example, Java Identifiers)

Example:

<web-app> <filter-mapping> <filter-name>CustomFilter</filter-name> // Error: either servlet-name or url-pattern child tag should be defined </filter-mapping> <servlet-mapping> <servlet-name>CustomServletName</servlet-name> <url-pattern>/ baseUrl</url-pattern> // Error: URI-pattern must not contain white spaces </servlet-mapping> </web-app>
