you need use structureid field when query journalarticles , passing structurekey value way

dynamicquery dynamicquerystructure = dynamicqueryfactoryutil.forclass(                 ddmstructure.class).add(propertyfactoryutil.forname("name").like(                 "%>empresa</name>%"));          list<ddmstructure> structures = ddmstructurelocalserviceutil.dynamicquery(dynamicquerystructure, 0, 1);         if(!structures.isempty()) {             string structurekey = structures.get(0).getstructurekey();             classloader cl = portalclassloaderutil.getclassloader();             dynamicquery dynamicquery = dynamicqueryfactoryutil.forclass(journalarticle.class, cl)                     .add(propertyfactoryutil.forname("structureid").eq(structurekey));             list<journalarticle> journalarticles = journalarticlelocalserviceutil.dynamicquery(dynamicquery);          }
