hi.. i've started with one problem , but ended up spilling my guts:) i have the lest jboss tools and eclipse 3.5.1, i suddenly noticed that if my hbm is not valid by the dtd i don't get a report in the xml editor, only in the tree editor. another problem i've stubmled upon is the use of entity reference causes problems with tree editor which does not recognizes it. and one last problem attempting to generate a graphical schema fails with classNotFound of one of my enums (a real enum) even though it's in the classpath and is schemaexport function working correctly? i'm not sure what i should to do to use, because i've also have hibernate lanuch configurations.
