Dear gurus ;)
I've just started playing around with SmartGWT 2.4, SmartGWTEE 2.4, Hibernate 3.6.2 and GWT 2.3.0, using Eclipse.
I am trying to program a very basic web app, where I can take out all my objects in a ListGrid. So far I am getting this error:
My files are as follows:
HibernateSmartGWTIlian.gwt.xml
HibernateSmartGWTIlian.java
server.properties
person.ds.xml
web.xml
My Hibernate are correct, I've already tested them on another project.
I can't seem to find the information that suits me and I'm quite a novice in the J2EE world. Could someone please direct me through the task and tell me where I'm messed up?
Thank you in advance,
Ilian
