While OGNL operates under +the assumption there is only one ârootâ, Strutsâs ValueStack concept requires there be many ârootsâ.</p> + +<p>For example, suppose we are using standard OGNL (not using Struts) and there are two objects in the OgnlContext map: +âfooâ -> foo and âbarâ -> bar and that the foo object is also configured to be the single <strong>root</strong> object. +The following code illustrates how OGNL deals with these three situations:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>#foo.blah // returns foo.getBlah() +#bar.blah // returns bar.getBlah() +blah // returns foo.getBlah() because foo is the root +</code></pre> +</div> + +<p>What this means is that OGNL allows many objects in the context, but unless the object you are trying to access is the root, +it must be prepended with a namespaces such as @bar. Now letâs talk about how Struts is a little differentâ¦</p> + +<blockquote> + <p>In Struts, the entire ValueStack is the root object in the context. Rather than having your expressions get the object +you want from the stack and then get properties from that (ie: peek().blah), Struts has a special OGNL PropertyAccessor +that will automatically look at the all entries in the stack (from the top down) until it finds an object with the property +you are looking for.</p> +</blockquote> + +<p>For example, suppose the stack contains two objects: Animal and Person. Both objects have a ânameâ property, Animal has +a âspeciesâ property, and Person has a âsalaryâ property. Animal is on the top of the stack, and Person is below it. +The follow code fragments help you get an idea of what is going on here:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>species // call to animal.getSpecies() +salary // call to person.getSalary() +name // call to animal.getName() because animal is on the top +</code></pre> +</div> + +<p>In the last example, there was a tie and so the animalâs name was returned. Usually this is the desired effect, but +sometimes you want the property of a lower-level object. To do this, XWork has added support for indexes on the ValueStack. +All you have to do is:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>[0].name // call to animal.getName() +[1].name // call to person.getName() +</code></pre> +</div> + +<p>With expression like <code class="highlighter-rouge">[0] ... [3]</code> etc. Struts will cut the stack and still return back a CompoundRoot object. To get +the top of that particular stack cut, use <code class="highlighter-rouge">[0].top</code></p> + +<table> + <thead> + <tr> + <th>ognl expression</th> + <th>description</th> + </tr> + </thead> + <tbody> + <tr> + <td><code class="highlighter-rouge">[0].top</code></td> + <td>would get the top of the stack cut starting from element 0 in the stack (similar to top in this case)</td> + </tr> + <tr> + <td><code class="highlighter-rouge">[1].top</code></td> + <td>would get the top of the stack cut starting from element 1 in the stack</td> + </tr> + </tbody> +</table> + +<h3 id="accessing-static-properties">Accessing static properties</h3> + +<p>OGNL supports accessing static properties as well as static methods.</p> + +<p>By default, Struts 2 is configured to disallow this - to enable OGNLâs static member support you must set the +<code class="highlighter-rouge">struts.ognl.allowStaticMethodAccess</code> constant to <code class="highlighter-rouge">true</code> via any of the <a href="../core-developers/constant-configuration.html">Constant Configuration</a> methods.</p> + +<p>OGNLâs static access looks like this:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>@some.package.ClassName@FOO_PROPERTY +@some.package.ClassName@someMethod() +</code></pre> +</div> + +<p>However, Struts allows you to avoid having to specify the full package name and call static properties and methods of your +action classes using the âvsâ prefix:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code><at:var at:name="vs" />FOO_PROPERTY +<at:var at:name="vs" />someMethod() + +<at:var at:name="vs1" />FOO_PROPERTY +<at:var at:name="vs1" />someMethod() + +<at:var at:name="vs2" />BAR_PROPERTY +<at:var at:name="vs2" />someOtherMethod() +</code></pre> +</div> + +<p>âvsâ stands for âvalue stackâ. The important thing to note here is that if the class name you specify is just âvsâ, +the class for the object on the top of the stack is used. If you specify a number after the âvsâ string, an objectâs +class deeper in the stack is used instead.</p> + +<h3 id="differences-from-the-webwork-1x-el">Differences from the WebWork 1.x EL</h3> + +<p>Besides the examples and descriptions given above, there are a few major changes in the EL since WebWork 1.x. The biggest +one is that properties are no longer accessed with a forward slash (/) but with a dot (.). Also, rather than using â..â +to traverse down the stack, we now use â[n]â where n is some positive number. Lastly, in WebWork 1.x one could access +special named objects (the request scope attributes to be exact) by using â@fooâ, but now special variables are accessed +using â#fooâ. However, it is important to note that â#fooâ does NOT access the request attributes. Because XWork is not +built only for the web, there is no concept of ârequest attributesâ, and thus â#fooâ is merely a request to another +object in the OgnlContext other than the root.</p> + +<table> + <thead> + <tr> + <th>Old Expression</th> + <th>New Expression</th> + </tr> + </thead> + <tbody> + <tr> + <td>foo/blah</td> + <td>foo.blah</td> + </tr> + <tr> + <td>foo/someMethod()</td> + <td>foo.someMethod()</td> + </tr> + <tr> + <td>../bar/blah</td> + <td>[1].bar.blah</td> + </tr> + <tr> + <td>@baz</td> + <td>not directly supported, but #baz is similar</td> + </tr> + <tr> + <td>.</td> + <td>âtopâ or [0]</td> + </tr> + </tbody> +</table> + +<h3 id="struts-2-named-objects">Struts 2 Named Objects</h3> + +<p>Struts 2 places request parameters and request, session, and application attributes on the OGNL stack.
