The Detail Info in below: [WrappedConnection] WARN Closing a statement you left open, please do your own housekeeping. I got connection from the DataSource. this is my sybase-ds.xml configuration <local-tx-datasource> <jndi-name>jdbc/eusr</jndi-name> <connection-url>jdbc:sybase:Tds:127.0.0.1:2638?ServiceName=eusr</connection-url> <driver-class>com.sybase.jdbc2.jdbc.SybDataSource</driver-class> <user-name>TTT</user-name> TTT <idle-timeout-minutes>5000</idle-timeout-minutes> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.SybaseExceptionSorter</exception-sorter-class-name> <min-pool-size>5</min-pool-size> <max-pool-size>30</max-pool-size> <type-mapping>Sybase</type-mapping> </local-tx-datasource> <local-tx-datasource> <jndi-name>jdbc/esys</jndi-name> <connection-url>jdbc:sybase:Tds:127.0.0.1:2638?ServiceName=esys</connection-url> <driver-class>com.sybase.jdbc2.jdbc.SybDataSource</driver-class> <user-name>TTT</user-name> TTT <idle-timeout-minutes>5000</idle-timeout-minutes> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.SybaseExceptionSorter</exception-sorter-class-name> <min-pool-size>5</min-pool-size> <max-pool-size>30</max-pool-size> <type-mapping>Sybase</type-mapping> </local-tx-datasource> Call the Connection code below: InitialContext initial = new InitialContext(); DataSource dataSource=null; if(name.indexOf("usr")!=-1) dataSource =(DataSource) initial.lookup("java:/jdbc/eusr"); else{ dataSource =(DataSource) initial.lookup("java:/jdbc/esys"); } Connection con = dataSource.getConnection(); return con; BTW, I got another WARN [TxConnectionManager$LocalXAResource] Prepare called on a local tx. Use of local transactions on a jta transaction with more than one branch may result in inconsistent data in some cases of failure. Maybe the solution that is to configure a tx DataSource I wonder ,did Sybase has tx Datasouce , my sybase version is 12.5.0 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4108740#...
