    • doStartTag

      public int doStartTag() throws jakarta.servlet.jsp.JspException
      doStart tag handler required to fulfill the Tag interface defined in the JSP specification.

      This method determines whether this request has come via the struts framework, by checking the value of the 'isStrutsRequest' request attribute. This is set on every request by the

      invalid reference 
      com.randomnoun.common.webapp.struts.RequestProcessor
      class. This tag is always empty, and therefore must always return BodyTag.SKIP_BODY
      Specified by:
      doStartTag in interface jakarta.servlet.jsp.tagext.Tag
      Overrides:
      doStartTag in class jakarta.servlet.jsp.tagext.BodyTagSupport
      Returns:
      BodyTag.SKIP_BODY
      Throws:
      jakarta.servlet.jsp.JspException

    • doEndTag

      public int doEndTag() throws jakarta.servlet.jsp.JspException
      doEnd tag handler required to fulfill the Tag interface defined in the JSP specification.

      This method enforces the presence of the 'isStrutsRequest' request attribute. If the attribute is present, then processing continues normally, otherwise an error message is given to the user, and the requested URL is sent to the logger of this class.

      Note that the output of this tag is *not* internationalised.

      Specified by:
      doEndTag in interface jakarta.servlet.jsp.tagext.Tag
      Overrides:
      doEndTag in class jakarta.servlet.jsp.tagext.BodyTagSupport
      Returns:
      BodyTag.SKIP_BODY or BodyTag.SKIP_PAGE
      Throws:
      jakarta.servlet.jsp.JspException
