    <b>Print property value, using the property tag
</p>
<p>
    On the OGNL demo you learned how to access values from the Value Stack using OGNL expressions.
    The <i>property tag is used to print to the page the result of an OGNL expression. The expression
    is specified in the <i>value attribute.
</p>
<p>To print the value of the expression name to the page type:
<p>
    <i id="example0">
        <s:property value="name" />
    </i>
</p>
<p>
    on the JSP console and hit enter. <a href="#" onclick="execJSP('example0')">Do it for me
</p>
<p>
    As you saw in the OGNL demo, to print a property of an object that is not on top of the stack,
    use the <i>#object.property notation.
</p>
<p>To print the value for the key "struts.view_uri" in request to the page type:
<p>
    <i id="example1">
        <s:property value="#request['struts.view_uri']" />
    </i>
</p>
<p>
    on the JSP console and hit enter. <a href="#" onclick="execJSP('example1')">Do it for me
</p>
<p>
    <b>Print property value, using the $ operator
</p>
<p>Use the ${name} notation to print values from the Value Stack to the page.
<p>To print the value of the expression name to the page type:
<p>
    <i id="example2">
        ${name}
    </i>
</p>
<p>
    on the JSP console and hit enter. <a href="#" onclick="execJSP('example2')">Do it for me
</p>
<p>
    <a href="#" onclick="window.open('http://struts.apache.org/2.x/docs/property.html')">[More details]
