How to access static fields using OGNL in Struts 2

[Andrei Antonescu]

Hello,

I am having a class that contains the "public static final x" variable. How can I use it into a OGNL expression in a web page using Struts 2 tags?
I would like to achieve smth like this:

  <s:if test="variableExpression==x">
            ...
           </s:if>  

Thank you in advance.

Your class will still need to have a getter method for the variable and the getter method cannot be static.

So if we have the following in our class:

  
   public static final String tstFinal = "string";

      //our getter
	public String getTstFinal() {
		return tstFinal;
	}

In our JSP we would test this way:

  
<s:if test="tstFinal == 'string'">
In here.
</s:if>

That is not correct; static variables are accessible just fine.

What David said is correct.

Doh! Your right!

Actually, it doesn't say anything about not being able to access static variables on that page. What it *does* say is that the *method* can't be static, but I don't think that's correct either: if you're configured to allow static access and use the OGNL static access syntax, it'll work. It's okay if you don't believe me, though.

Also, when linking to the online docs, make sure you link to (a) the most recent version (or version-specific when the version is known), and (b) not the cwiki.apache.org site, but rather the struts.apache.org site. Thanks.
