Accessing public static final constants from JXTemplate

Hi All,


I have a class called Constants, that is like this:

public final class Constants {
	public static final String FAILURE = "Failed";
	public static final String CANCEL_ACTION = "Cancelled";
	// etc.
}

I wish to share this between my Java 'biz logic', my FlowScripts and 
the View Layer.

  I have the first two working as expected, the third I cannot work out 
.....

Is it possible to pass the Constants class to the JXTemplate view layer 
in such a way that I can extract their values?

I have tried several ways of sending the Constants class to the view 
layer, and using #{CANCEL_ACTION} (etc.) in my template, without 
success.

Any suggestions?

thanks

regards Jeremy

I am running Cocoon2.1RC1, so I will update the server and try again.

Many thanks

This should work:

${Packages.org.iniva.util.Contstants.CANCEL_ACTION}

But make sure you update to the latest cvs. I only recently added a fix 
for this.

I have tried the following expressions in JXTemplate :

#{org/iniva/util/Constants/CANCEL_ACTION}                 : No pointer 
for xpath Exception
#{Packages/org/iniva/util/Constants/CANCEL_ACTION} : No pointer for 
xpath Exception
#{org.iniva.util.Constants.CANCEL_ACTION}                   : no output
#{Packages.org.iniva.util.Constants. CANCEL_ACTION}   : no output
#{java.org.iniva.util.Constants. CANCEL_ACTION}            : no output
${org.iniva.util.Constants.CANCEL_ACTION}                    : no output
${Packages.org.iniva.util.Constants. CANCEL_ACTION}    : no output
${java.org.iniva.util.Constants. CANCEL_ACTION}            :
			outputs "[JavaPackage java.org.iniva.util.Constants. CANCEL_ACTION]"


So I am not any closer ......

Any suggestions?

Thanks
