Thank You Jeffrey, but I did as u told me but anything changed.... Here is the DS definition: *<local-tx-datasource> <jndi-name>jdbc_XA/Drools_Rep</jndi-name> <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <connection-url>jdbc:oracle:thin:@localhost:1521:xe</connection-url> <user-name>...</user-name> <password>...</password> <exception-sorter-class-name> org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter </exception-sorter-class-name> <metadata> <type-mapping>Oracle9i</type-mapping> </metadata> <use-java-context>false</use-java-context> </local-tx-datasource>* ... I got back the same exception even with the local-tx Datasource!! *17:35:33,430 INFO [STDOUT] PackageName: com.spyd.rules.Scoring* *17:35:33,430 INFO [STDOUT] PackageVersion: Scoring* *17:35:33,430 INFO [STDOUT] PackageIsLatest: false* *----* *(I THINK THIS ONE DOES NOT REALLY MATTER)* *17:35:43,559 INFO [STDOUT] ERROR 22-02 17:35:43,558 (** Contexts.java:flushAndDestroyContexts:335**) could not discover transaction status* *----* *17:35:43,560 INFO [CachedConnectionManager] Closing a connection for you.

So... Why do I get this kind of issues once I use the Datasource???? Can You advise me any way to (at least) reduce the exception waiting time? Let me know. Thank again Massi
