Dialects cannot use the Thread Context ClassLoader with AS7, please change to use the -------------------------------------------------------------------------------------- Key: HHH-6073 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6073 Project: Hibernate Core Issue Type: Task Reporter: Scott Marlow Assignee: Steve Ebersole Priority: Blocker Fix For: 4.0.0.Alpha2 We can no longer rely on TCCL because AS7 is following a modular class loading approach. The AS7 "org.hibernate" module isn't setup to access the JDBC classes. We discussed changing the dialects to not use the TCCL as a workaround. Or perhaps passing in a ClassLoaderService. The following warning shows what we currently see with Hibernate 3.6.1 and the DerbyDialect (TCCL is null). 08:45:27,597 INFO [org.hibernate.dialect.Dialect] (MSC service thread 1-6) Using dialect: org.hibernate.dialect.DerbyDialect 08:45:27,603 INFO [org.hibernate.dialect.Dialect] (MSC service thread 1-2) Using dialect: org.hibernate.dialect.DerbyDialect 08:45:27,614 WARN [org.hibernate.dialect.DerbyDialect] (MSC service thread 1-6) Unable to load/access derby driver class sysinfo to check versions : java.lang.ClassNotFoundException: org.apache.derby.tools.sysinfo from [Module "org.hibernate:main" from local module loader @fee4648 (roots: /work/as7-dev/jboss-as/build/target/jboss-7.0.0.Beta2/modules)] 08:45:27,616 WARN [org.hibernate.dialect.DerbyDialect] (MSC service thread 1-2) Unable to load/access derby driver class sysinfo to check versions : java.lang.ClassNotFoundException: org.apache.derby.tools.sysinfo from [Module "org.hibernate:main" from local module loader @fee4648 (roots: /work/as7-dev/jboss-as/build/target/jboss-7.0.0.Beta2/modules)]
