  <info>
  <p>This tag library contains tags that are useful in managing conditional
  generation of output text, looping over object collections for
  repetitive generation of output text, and application flow management.</p>

  <p>For tags that do value comparisons (<code>equal</code>,
  <code>greaterEqual</code>, <code>greaterThan</code>, <code>lessEqual</code>,
  <code>lessThan</code>, <code>notEqual</code>), the following rules apply:</p>
  <ul>
  <li>The specified value is examined.  If it can be converted successfully
      to a <code>double</code> or a <code>long</code>, it is assumed that the
      ultimate comparison will be numeric (either floating point or integer).
      Otherwise, a String comparison will be performed.</li>
  <li>The variable to be compared to is retrieved, based on the selector
      attribute(s) (<code>cookie</code>, <code>header</code>,
      <code>name</code>, <code>parameter</code>, <code>property</code>)
      present on this tag.  It will be converted to the appropriate type
      for the comparison, as determined above.</li>
  <li>If the specified variable or property returns null, it will be
      coerced to a zero-length string before the comparison occurs.</li>
  <li>The specific comparison for this tag will be performed, and the nested
      body content of this tag will be evaluated if the comparison returns
      a <code>true</code> result.</li>
  </ul>

  <p>For tags that do substring matching (<code>match</code>,
  <code>notMatch</code>), the following rules apply:</p>
  <ul>
  <li>The specified variable is retrieved, based on the selector attribute(s)
      (<code>cookie</code>, <code>header</code>, <code>name</code>,
      <code>parameter</code>, <code>property</code>) present on this tag.
      The variable is converted to a String, if necessary.</li>
  <li>A request time exception will be thrown if the specified variable
      cannot be retrieved, or has a null value.</li>
  <li>The specified value is checked for existence as a substring of the
      variable, in the position specified by the <code>location</code>
      attribute, as follows:  at the beginning (if location is set to
      <code>start</code>), at the end (if location is set to
      <code>end</code>), or anywhere (if location is not specified).</li>
  </ul>

  <p>Many of the tags in this tag library will throw a
  <code>JspException</code> at runtime when they are utilized incorrectly
  (such as when you specify an invalid combination of tag attributes).  JSP
  allows you to declare an "error page" in the <code>&lt;%@ page %&gt;</code>
  directive.  If you wish to process the actual exception that caused the
  problem, it is passed to the error page as a request attribute under key
  <code>org.apache.struts.action.EXCEPTION</code>.</p>

    <summary>
    Evaluate the nested body content of this tag if the requested variable is
    either <code>null</code> or an empty string.

    <tagclass>org.apache.struts.taglib.logic.EmptyTag</tagclass>
    <bodycontent>JSP</bodycontent>
    <since>Struts 1.1</since>
    <info>
    <p>This tag evaluates its nested body content only if the specified value
    is either absent (i.e. <code>null</code>), an empty string (i.e. a
    <code>java.lang.String</code> with a length of zero), or an empty
    <code>java.util.Collection</code> or <code>java.util.Map</code> (tested by
    the .isEmpty() method on the respective interface).</p>
    
    <p>
    <strong>JSTL</strong>:  The equivalent JSTL tag is &lt;c:if&gt; using the 
    <code>empty</code> operator.  For example,
    <br/>
    <code>
    	&lt;c:if test="${empty sessionScope.myBean.myProperty}"&gt;
    	  do something
    	&lt;/c:if&gt;

    <name>iterate</name>
    <summary>
    Repeat the nested body content of this tag over a specified collection.

    <tagclass>org.apache.struts.taglib.logic.IterateTag</tagclass>
    <teiclass>org.apache.struts.taglib.logic.IterateTei</teiclass>
    <bodycontent>JSP</bodycontent>
    <info>
    <p>Repeats the nested body content of this tag once for every element
    of the specified collection, which must be an <code>Iterator</code>,
    a <code>Collection</code>, a <code>Map</code> (whose values are to be
    iterated over), or an array.  The collection to be iterated over must be
    specified in one of the following ways:</p>
    <ul>
    <li>As a runtime expression specified as the value of the
        <code>collection</code> attribute.</li>
    <li>As a JSP bean specified by the <code>name</code> attribute.</li>
    <li>As the property, specified by the <code>property</code>, of the
        JSP bean specified by the <code>name</code> attribute.</li>
    </ul>

    <p>The collection to be iterated over MUST conform to one of the following
    requirements in order for iteration to be successful:</p>
    <ul>
    <li>An array of Java objects or primitives.</li>

    <li>An implementation of <code>java.util.Collection</code>, including
        <code>ArrayList</code> and <code>Vector</code>.</li>
    <li>An implementation of <code>java.util.Enumeration</code>.</li>
    <li>An implementation of <code>java.util.Iterator</code>.</li>
    <li>An implementation of <code>java.util.Map</code>, including
        <code>HashMap</code>, <code>Hashtable</code>, and
        <code>TreeMap</code>.  <strong>NOTE</strong> - See below for
        additional information about accessing Maps.</li>
    </ul>

    <p>Normally, each object exposed by the iterate tag is an element
    of the underlying collection you are iterating over.  However, if you
    iterate over a <code>Map</code>, the exposed object is of type
    <code>Map.Entry</code> that has two properties:</p>
    <ul>
    <li><code>key</code> - The key under which this item is stored in the
        underlying Map.</li>
    <li><code>value</code> - The value that corresponds to this key.</li>
    </ul>

    <p>So, if you wish to iterate over the values of a Hashtable, you would
    implement code like the following:</p>
    <code>
    &lt;logic:iterate id="element" name="myhashtable"&gt;<br/>
      Next element is &lt;bean:write name="element" property="value"/&gt;<br/>
    &lt;/logic:iterate&gt;
    </code>

    <p>If the collection you are iterating over can contain <code>null</code>
    values, the loop will still be performed but no page scope attribute
    (named by the <code>id</code> attribute) will be created for that loop
    iteration.  You can use the <code>&lt;logic:present&gt;</code> and
    <code>&lt;logic:notPresent&gt;</code> tags to test for this case.</p>

                <summary>Render an HTTP Redirect</summary>
                <tagclass>org.apache.struts.taglib.logic.RedirectTag</tagclass>
                <body-content>empty</body-content>
                <info>

                <p>Performs an <code>HttpServletResponse.sendRedirect()</code>
                call to the hyperlink specified by the attributes to this
                tag.  URL rewriting will be applied automatically, to
                maintain session state in the absence of cookies.</p>

                <p>The base URL for this redirect is calculated based on
                which of the following attributes you specify (you must
                specify exactly one of them):</p>
                <ul>
                <li><em>forward</em> - Use the value of this attribute as the
                    name of a global <code>ActionForward</code> to be looked
                    up, and use the application-relative or context-relative
                    URI found there.</li>
                <li><em>href</em> - Use the value of this attribute unchanged.
                    </li>
                <li><em>page</em> - Use the value of this attribute as an
                    application-relative URI, and generate a server-relative
                    URI by including the context path.</li>
                </ul>

                <p>Normally, the redirect you specify with one of the
                attributes described in the previous paragraph will be left
                unchanged (other than URL rewriting if necessary).  However,
                there are two ways you can append one or more dynamically
                defined query parameters to the hyperlink -- specify a single
                parameter with the <code>paramId</code> attribute (and its
                associated attributes to select the value), or specify the
                <code>name</code> (and optional <code>property</code>)
                attributes to select a <code>java.util.Map</code> bean that
                contains one or more parameter ids and corresponding values.
                </p>

                <p>To specify a single parameter, use the <code>paramId</code>
                attribute to define the name of the request parameter to be
                submitted.  To specify the corresponding value, use one of the
                following approaches:</p>
                <ul>
                <li><em>Specify only the <code>paramName</code> attribute</em>
                    - The named JSP bean (optionally scoped by the value of the
                    <code>paramScope</code> attribute) must identify a value
                    that can be converted to a String.</li>
                <li><em>Specify both the <code>paramName</code> and
                    <code>paramProperty</code> attributes</em> - The specified
                    property getter method will be called on the JSP bean
                    identified by the <code>paramName</code> (and optional
                    <code>paramScope</code>) attributes, in order to select
                    a value that can be converted to a String.</li>
                </ul>

                <p>If you prefer to specify a <code>java.util.Map</code> that
                contains all of the request parameters to be added to the
                hyperlink, use one of the following techniques:</p>
                <ul>
                <li><em>Specify only the <code>name</code> attribute</em> -
                    The named JSP bean (optionally scoped by the value of
                    the <code>scope</code> attribute) must identify a
                    <code>java.util.Map</code> containing the parameters.</li>
                <li><em>Specify both <code>name</code> and
                    <code>property</code> attributes</em> - The specified
                    property getter method will be called on the bean
                    identified by the <code>name</code> (and optional
                    <code>scope</code>) attributes, in order to return the
                    <code>java.util.Map</code> containing the parameters.</li>
                </ul>

                <p>As the <code>Map</code> is processed, the keys are assumed
                to be the names of query parameters to be appended to the
                hyperlink.  The value associated with each key must be either
                a String or a String array representing the parameter value(s).
                If a String array is specified, more than one value for the
                same query parameter name will be created.</p>
                </info>

                  <name>anchor</name>
