<div class="content wysiwyg-content">
I have a java constant defined as follows:<br />
public static final String ACCESS_ROLE=&quot;accessRole&quot;.<br />
<br />
In a struts action class I set this attribute in a session sesssion.setAttribute(Cons<wbr />tants.ACCE<wbr />SS_ROLE, &quot;adminrole&quot;);<br />
<br />
In my JSP I am using JSTL. How could I use JSTL to check that the attribute exists in the session, i know how to do it using the actual string value such as <br />
<br />
&lt;c:if test=&quot;${(sessionScope.acce<wbr />ssRole == 'true') }&quot; &gt;&nbsp;but how would I use Constant.ACCESS_ROLE in the if expression?<br />

How to refer to a constant using JSTL

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.
