If property !=null tag?

Hi,

i want a part of my JSP code to be ignored, if a property in my Actionbean
is null. 
Any idea for this in struts without too much JSP code ?

Thanks in advance,

Stefan

If property !=null tag?Hi,
I used the <ifPropertyNotEquals> tag like this:

<struts:ifPropertyNotEquals name="ViewOrderForm"
                            property="orderLI"
                            value="" >

It seems to work fine.  The property orderLI is an array which if there is no value in it returns null to the JSP.  I don't think this tag is documented for some reason.  I'm using struts version 0.5.  If there is a better way I'd like to hear about it!

If you are using Struts 1.0, have you tried?

<logic:present name="yourForm" property="yourProp" >
            Shown only when yourProp is not null
</logic:present>
