JDOQL query for none empty


 Anybody knows if it is possible to query for none_empty values with JDOQL?


	    @javax.jdo.annotations.Query(

	            name = "allDemandProfiles", language = "JDOQL",

	            value = "SELECT "

	                    + "FROM info.matchingservice.dom.Profile.Profile "

	                    + "WHERE demandProfileOwner != Null")  

	Does not work...

Hi Johan,

should it not be simply "==null"  (lowercase) ?
