+<subsection name="Will the Struts tags support other markup languages such as

+<p>
+Struts itself is markup neutral. The original Struts taglibs are only one
example of how
+presentation layer components can access the framework. The framework objects
are exposed
+through the standard application, session, and request contexts, where any
Java component in
+the application can make use of them.
+</p>
+
+<p>Markup extensions that use Struts are available for
+<a href="http://jakarta.apache.org/velocity";>Velocity</a> and
+<a href="http://www.openroad.ca/opencode/";>XLST</a>, among others.
+A new Struts tag library for

+</subsection>
+
+<a name="multiple"/>
+<subsection name="Can I use multiple HTML form elements with the same name?">
+<p>
+Yes. Define the element as an array and Struts will autopopulate it like any
other.
+</p>
+<pre>
+<code>
+private String[] id= {};
+public String[] getId() { return this.id; }
+public void setItem(String id[]) {this.id = id;}
+</code>
+</pre>
+<p>
+And so forth
+</p>
+</subsection>
+
+<a name="multipleSubmits"/>
+<subsection name="Can I have multiple submit buttons on the same form?">
+<p>
+<strong>Yes</strong>. The issue is that only one action class can be
+associated with a single form. So the real issue is how do I decode
+multiple submit types to a single <code>Action</code> class.
+There is more than one way to achieve this functionality.</p>
+<p>
+The way that is suggested by struts is right out of the javadoc for
+<a href="../api/org/apache/struts/actions/LookupDispatchAction.html">
+<code>LookupDispatchAction</code></a>.
+Basically, <code>LookupDispatchAction</code> is using the keys from
+<code>ApplicationProperties.resources</code> as keys to a map of actions
+available to your <code>Action</code> class. It uses
+<a href="http://java.sun.com/j2se/1.3/docs/guide/reflection/";>reflection</a> to
+decode the request and invoke the proper action. It also takes advantage of
+the struts <a href="../userGuide/struts-html.html#submit">
+<code><html:submit></code></a> tags and is straight forward to
implement.</p>
+<p>
+You can roll your own with JavaScript events and <code>javascript:void
+(document.forms["myform"].submit)</code> on any html element. This gives you
+control of how you want your page to look. Again you
+will have to decode the expected action in the <code>execute</code> method of
+your action form if you choose this route.</p>
+</subsection>
+
+<a name="focus"/>
+<subsection name="Why doesn't the focus feature on the <html:form> tag work
in every circumstance?">
+<p>
+Unfortunately, there is some disagreement between the various browsers, and
different versions of the same browser, as to how the focus can be set.
+The <html:form> tag provides a quick and easy JavaScript that will set the
focus on a form
+for most versions of most browsers.
+If this feature doesn't work for you, then you should set the focus using your
own JavaScript.
+The focus feature is a convenient "value-add" -- not a core requirement of the
tag.
+If you do come up with a JavaScript that provides the final solution to this
project,
+please post your patch to this <a
href="http://issues.apache.org/bugzilla/show_bug.cgi?id=13454";>Bugzilla
ticket</a>.
+</p>
+</subsection>
+
+<a name="checkbox"/>
+<subsection name="Why are my checkboxes not being set from ON to OFF?">
+<p>
+A problem with a checkbox is that the browser will only include it in the
request
+when it is checked. If it is not checked, the HTML specification suggests that
it
+not be sent (i.e. omitted from the request). If the value of the checkbox is
being
+persisted, either in a session bean or in the model, a checked box can never
+unchecked by a HTML form -- because the form can never send a signal to uncheck
+the box. The application must somehow ascertain that since the element was not
+sent that the corresponding value is unchecked.
+</p>
+<p>
+The recommended approach for Struts applications is to use the reset method in
the
+ActionForm to set all properties represented by checkboxes to null or false.
The
+checked boxes submitted by the form will then set those properties to true. The
+omitted properties will remain false. Another solution is to use radio buttons
+instead, which always submit a value.
+</p>
+<p>
+It is important to note that the HTML specification recommends this same
+behavior whenever a control is not "successful". Any blank element in a HTML
+form is not guaranteed to submitted. It is therefor very important to set the
+default values for an ActionForm correctly, and to implement the reset method
+when the ActionForm might kept in session scope.
+</p>
+</subsection>
+
+<a name="javascript.submit"/>
+<subsection name="Can I use JavaScript to submit a form?">
+<p>
+ You can submit a form with a link as below.
+ BTW, the examples below assume you are in an <html:form> block and
'myForm'
+ is picked up from the struts-config.xml name field of the action.
+</p>
+<source>
+ <a href='javascript:void(document.forms["myForm"].submit()>My
Link</a>
+</source>
+<p>
+ Now the trick in the action is to decode what action you intend to perform.
+ Since you are using JavaScript, you could set a field value and look for
it in
+ the request or in the form.
+</p>
+<p>
+ ... html/javascript part ...
+</p>
+<source>
+ <input type='hidden' value='myAction' />
+ <input type='button' value='Save Meeeee'
+ onclick='document.forms["myForm"].myAction.value="save";
+ document.forms["myForm"].submit();' />
+ <input type='button' value='Delete Meeeee'
+ onclick='document.forms["myForm"].myAction.value="delete";
+ document.forms["myForm"].submit();' />
+</source>
+<p>
+ ... the java part ...
+</p>
+<source>
+ class MyAction extends ActionForm implements Serializable {
+
+ public ActionForward execute (ActionMapping map, ActionForm form,
+ HttpServletRequest req, HttpServletResponse) {
+
+ String myAction = req.getParameter("myAction");
+
+ if (myAction.equals("save") {
+ // ... save action ...
+ } else if (myAction.equals("delete") {
+ // ... delete action ...
+ }
+ }
+ }
+ }
+</source>
+<p>
+ This is just one of many ways to achieve submitting a form and decoding the
+ intended action. Once you get used to the framework you will find other
ways
+ that make more sense for your coding style and requirements. Just remember
+ this example is completely non-functional without JavaScript.
+</p>
+<p>
+ Here is a link
+ which utilizes the LookupDispatch action to submit forms with multiple
actions
+ without javascript: <a

+
+</subsection>
+
+<a name="javascript"/>
+<subsection name="How do I use JavaScript to ...">
+
+ <p>
+ Struts is mainly a server-side technology.
+ We bundled in some JSP tags to expose the framework components to your
+ presentation page, but past that, the usual development process applies.
+ </p>
+
+ <p>
+ Interactive pages require the use of JavaScript.
+ (That's why it was invented.)
+ If you want things popping up or doing this when they click that,
+ you are outside the scope of Struts and back into the web
+ development mainstream.
+ </p>
+
+ <p>
+ You use JavaScript with Struts the same way you use with any presentation
+ page.
+ Since JavaScript is a client-side technology, you can use simple relative
+ references to your scripts.
+ If you need to fire a JavaScript from a HTML control, the Struts HTML tags
+ have properties for the JavaScript events.
+ </p>
+
+ <p>
+ A very good JavaScript resource is Matt Kruse's site at
+ <a href="http://www.mattkruse.com/javascript/";>
+ http://www.mattkruse.com/javascript/</a>
+ </p>
+
+</subsection>
+
+<a name="reset"/>
+<subsection name="Do I need to implement reset and set all my form properties
to their initial values?">
+<p>
+No.
+You need to set checkbox properties to false if the ActionForm is being
retained in session scope.
+This is because an unchecked box does not submit an attribute.
+Only checked boxes submit attributes.
+If the form is in session scope, and the checkbox was checked, there is no way
to turn it back off without the reset method.
+Resetting the properties for other controls, or for a request scope form, is
pointless.
+If the form is in request scope, everything already just started at the
initial value.
+</p>
+</subsection>
+
+<a name="scriptlets"/>
+<subsection name="Can't I just create some of my JavaBeans in the JSP using a
scriptlet?">
+<p>
+Struts is designed to encourage a
+<a href="http://www.javaworld.com/javaworld/jw-12-1999/jw-12-ssj-jspmvc.html";>
+Model 2/MVC architecture</a>. But there is nothing that prevents you from
using Model 1
+techniques in your JavaServer Pages, so the answer to the question is "Yes,
you can".
+</p>
+<p>
+Though, using Model 1 techniques in a Struts application does go against the
grain.
+The approach recommended by most Struts developers is to create and populate
whatever
+objects the view may need in the Action, and then forward these through the
request.
+Some objects may also be created and stored in the session or context,
+depending on how they are used.
+</p>
+<p>
+Likewise, there is nothing to prevent you from using scriptlets along with JSP
+tags in your pages. Though, many Struts developers report writing very complex
+scriplet-free applications and recommend the JSP tag approach to others.
+</p>
+<p>
+For help with Model 1 techniques and scriptlets, you might consider joining the
+<a href="http://archives.java.sun.com/jsp-interest.html";>Javasoft JSP-interest
+mailing list</a>, where there are more people still using these approaches.
+</p>
+</subsection>
+
+<a name="link"/>
+<subsection name="Why does the <html:link> tag URL-encode javascript and
mailto links?">
+<p>
+The <html:link> tag is not intended for use with client-side references
like those used to launch Javascripts or email clients.
+The purpose of link tag is to interject the context (or module) path into the
URI so that your server-side links are not dependent on your context (or
module) name.
+It also encodes the link, as needed, to maintain the client's session on the
server.
+Neither feature applies to client-side links, so there is no reason to use the
<html:link> tag.
+Simply markup the client-side links using the standard <a/> tag.
+</p>
+</subsection>
+
+<a name="pager"/>
+<subsection name="How can I scroll through list of pages like the search
results in google?">
+<p>Many Struts developers use the Pager from the JSPTags site.</p>
+<p><a
href="http://jsptags.com/tags/navigation/pager/";>http://jsptags.com/tags/navigation/pager/</a></p>
+</subsection>
+
+<a name="minimization"/>
+<subsection name="Why does the option tag render selected=selected instead of
just selected?">
+<p>
+Attribute minimization (that is, specifying an attribute with no value) is
+a place where HTML violates standard XML syntax rules. This matters a lot
+for people writing to browsers that support XHTML, where doing so makes
+the page invalid.It's much better for Struts to use the expanded syntax,
+which works the same on existing browsers interpreting HTML, and newer
+browsers that expect XHTML-compliant syntax. Struts is following the
+behavior recommended by the <a href="http://www.w3.org/TR/xhtml1/#h-4.5";>
+XHTML specification</a></p>
+</subsection>
+
+<a name="tags"/>
+<subsection name="Why does Struts Taglib provide for so little formatting?">
+<p>
+<em>The Struts tags seem to provide only the most rudimentary functionality.
+Why is there not better support for date formatting and advanced string
handling?</em>
+</p>
+<p>
+Three reasons:
+</p>
+<p>
+First, work started on the JSTL and we didn't want to duplicate the effort.
+</p>
+<p>
+Second, work started on Java Server Faces, and we didn't want to duplicate
that effort either.
+</p>
+<p>
+Third, in a Model 2 application, most of the formatting can be handled in the
ActionForms (or in the business tier),
+so all the tag has to do is spit out a string.
+This leads to better reuse since the same "how to format" code does not need
to be repeated in every instance.
+You can "say it once" in a JavaBean and be done with it.
+</p>
+</subsection>
+
+<a name="layout"/>
+<subsection name="Why doesn't Struts Taglib offer more layout options?">
+<p>
+For more flexible placement of error messages,
+try the <a href="http://www.rabago.net/struts/html2/";><html2></a> Tag
Library for Struts.
+</p>
+<p>
+Since the Struts tags are open source, you can extend them to provide whatever
additional formatting you may need.
+If you are interested in a pre-written taglib that offers more layout options,
see the
+<a href="http://struts.application-servers.com";>struts-layout taglib</a>.
+</p>
+<p>
+In the same arena, there is a well regarded contributor taglib that can help
you create
+<a href="http://sourceforge.net/projects/struts-menu/";>Menus for your Struts
applications</a>.
+</p>
+<p>
+Another very popular tag library is <a
href="http://displaytag.sourceforge.net";>DisplayTag</a>.
+DisplayTag is an excellent choice when you have tabular data to present.
+</p>
+</subsection>
+
+<a name="undocumented"/>
+<subsection
+ name="If you would like to contribute, here is a list of
+ popular but undocumented questions">
+
+ <ul>
+
+
+ <li>Why do my option lists disappear when validation fails?</li>
+
+ <li>Why can't I disable URL-encoding in the Struts taglibs?</li>
+
