    • populateParams

      protected void populateParams()
      Description copied from class: ComponentTagSupport
      Define method to populate component state based on the Tag attributes. Descendants should override this method for custom behaviour, but should always call the ancestor method when doing so.
      Overrides:
      populateParams in class ContextBeanTag

      Must declare the setter at the descendant Tag class level in order for the tag handler to locate the method.
      Overrides:
      setPerformClearTagStateForTagPoolingServers in class ContextBeanTag
      Parameters:
      performClearTagStateForTagPoolingServers - true if tag state should be cleared, false otherwise.
    • clearTagStateForTagPoolingServers

      protected void clearTagStateForTagPoolingServers()
      Description copied from class: StrutsBodyTagSupport
      Provide a mechanism to clear tag state, to handle servlet container JSP tag pooling behaviour with some servers, such as Glassfish.

      Usage: Override this method in descendant classes to clear any state that might cause issues should the servlet container re-use a cached instance of the tag object. If the descendant class does not declare any new field members then it should not be strictly necessary to call this method there. Typically that means calling the ancestor's ComponentTagSupport.clearTagStateForTagPoolingServers() method first, then resetting instance variables at the current level to their default state.

      Note: If the descendant overrides StrutsBodyTagSupport.doEndTag(), and does not call super.doEndTag(), then the descendant should call this method in the descendant doEndTag() method to ensure consistent clearing of tag state.

      Overrides:
      clearTagStateForTagPoolingServers in class ContextBeanTag
