Hi I use a JBoss4.0.5 with clustering and EJB3.0 profile. I have defined the following Oracle datasource: <datasources> | <local-tx-datasource> | <jndi-name>idmDS</jndi-name> | <connection-url>jdbc:oracle:oci:@myDatabase</connection-url> | <!-- | | Here are a couple of the possible OCI configurations. | For more information, see http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/java.92... | tm | | <connection-url>jdbc:oracle:oci:@youroracle-tns-name</connection-url> | or | <connection-url>jdbc:oracle:oci:@(description=(address=(host=youroraclehost)(protocol=tcp)(port=1521))(connect_data=(SERV | ICE_NAME=yourservicename)))</connection-url> | | Clearly, its better to have TNS set up properly. | --> | <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> | <user-name>user</user-name> | <password>password</password> | <min-pool-size>1</min-pool-size> | <max-pool-size>20</max-pool-size> | <idle-timeout-minutes>40</idle-timeout-minutes> | <!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool --> | <!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection | -checker-class-name--> | <!-- Checks the Oracle error codes and messages for fatal errors --> | <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> | <!-- sql to call when connection is created | <new-connection-sql>some arbitrary sql</new-connection-sql> | --> | | <!-- sql to call on an existing pooled connection when it is obtained from pool - the OracleValidConnectionChecker is pre | fered | <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql> | --> | | <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> | <metadata> | <type-mapping>Oracle10i</type-mapping> | </metadata> | </local-tx-datasource> | | </datasources> | The datasource is injected in a stateful session bean. @Stateful | @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) | @org.jboss.annotation.ejb.cache.tree.CacheConfig(idleTimeoutSeconds = 3000) | @org.jboss.annotation.ejb.cache.simple.CacheConfig(idleTimeoutSeconds = 3000) | public class SDOCIBusinessServiceImpl implements SDOCIBusinessService { | | @Resource(mappedName = "java:idmDS") | private DataSource idmDataSource; | The datasource is used in the following method: public RolesDO login(String username, String password) throws SDOCIBusinessException { | _logger.info("login for user:" + username + " started... "); | OracleCallableStatement cstmt = null; | OracleConnection connection=null; | | try { | Connection conn = idmDataSource.getConnection(); | connection = (OracleConnection) ((WrappedConnection) conn).getUnderlyingConnection(); | Everytime this method is executed JBoss reuses a connection which is already in use by another instance of the staeful session bean. How can I make sure that JBoss pulls a new connection out of the ConnectionPool for every new instance of the stateful session bean? Any help?
