[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-579?page=co... ] Olaf Bigalk commented on HHH-579: --------------------------------- We have the same issue with JBoss 4.0.5 and Hibernate 3.2.1.ga. We get a ClassCastException in getTables. We are using Oracle 9i JDBC Driver (9.2.0.8). java.lang.ClassCastException at $Proxy60.getTables(null:-1) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.getTableMetadata(DatabaseMetadata.java:67) at org.hibernate.cfg.Configuration.validateSchema(Configuration.java:1071) at org.hibernate.tool.hbm2ddl.SchemaValidator.validate(SchemaValidator.java:116) I checked out the above link but I didn't find any hint how to configure either Hibernate or JBoss to prevent this problem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
