Hi, I've been developed a JEE application and used a JBoss AS version 4.2.1 default configuration to deploy it. This application access SQL-Server database through persistence unit and datasource configuration that uses Hibernate Entity Manager(default JBoss Configuration) and have worked fine. Now I need to access Teradata database, but is ok, I simply add a new datasource configuration file and adjusted persistence unit what worked perfectly with one problem, deploy work and application to but the console of Jboss AS stopped whith these two last lines console message: 09:26:23,640 INFO [ConnectionProviderFactory] Initializing connection provider: org.hibernate.ejb.connection.InjectedDataSourceConnectionProvider 09:26:23,656 INFO [InjectedDataSourceConnectionProvider] Using provided datasource And after these messages I "lost" the running application log. For example, when a error happened on application the console log don't show any log message after these messages. There are the configuration files: --> mssql-ds.xml | <?xml version="1.0" encoding="UTF-8"?> | <datasources> | <local-tx-datasource> | <jndi-name>jdbc/SQLServerDS</jndi-name> | <connection-url>jdbc:sqlserver://SQL_SERVER;DatabaseName=soa_new</connection-url> | <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class> | <user-name>user</user-name> | <password>pass</password> | </local-tx-datasource> | </datasources> | --> teradata-ds.xml | <?xml version="1.0" encoding="UTF-8"?> | <datasources> | <local-tx-datasource> | <jndi-name>jdbc/TeradataDS</jndi-name> | <connection-url>jdbc:teradata://TERADATA/database=DB_SOA</connection-url> | <driver-class>com.ncr.teradata.TeraDriver</driver-class> | <user-name>user</user-name> | <password>pass</password> | </local-tx-datasource> | </datasources> | --> persistence.xml | <?xml version="1.0" encoding="UTF-8"?> | <persistence> | <persistence-unit name="TeradataPU"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:jdbc/TeradataDS</jta-data-source> | <class> OMITTED CLASSES </class> | <exclude-unlisted-classes /> | <properties> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.dialect" value="org.hibernate.dialect.TeradataDialect"/> | </properties> | </persistence-unit> | <persistence-unit name="SqlServerPU"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:jdbc/SQLServerDS</jta-data-source> | <class> OMITTED CLASSES </class> | <exclude-unlisted-classes /> | <properties> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/> | </properties> | </persistence-unit> | </persistence> | I Thank you indeed in advance.
