Hello everyone,
I am trying to run a very simple application using GWT (1.6.4) and Hibernate (3.3.1) together.
I keep getting this error
:
Initial SessionFactory creation failed.
java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
I get the exception at this point in my simple HibernateUtil after an RPC call is made to the server and the server tries to create a SessionFactory to handle the transaction:
I get the exception at this line ---> Configuration config =new Configuration().configure();
I use the following xml:
YES, I have both the slf4j api and the slf4j-simple jar in my classpath. (tried NOP and slf4j-log4j instead of simple as well)
YES, I have tried both slf4j 1.5.6 and 1.5.2
Even though the LoggerFactory is right there in the api I get the ClassDefNotFound error.
I am guessing there is a clash with some other library...
My classpath contains :
gwt-user.jar
c3p0-0.8.5.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
ejb3-persistence.jar
hibernate3.jar
