I hope that iam not clear in stating why I need a direct connection from IBATIS, will correctly state is now.
My project runs in JBoss in one location and in tomcat in other places. Code base is same. There are some java EOD programs which will also run as separate process using IBATIS. Tomcat is not configured with a datasource but JBoss is. Hence I managed to define two <context> tags in the ibatis config file, and I will choose the context dynamically based on the server in which the project runs. The first context will use datasource and the other will use simple jdbc connection pool. Some of our code were using oracle tag libraries and some servlets to get oracle images and streaming media from the database. These tag libraries expect a connection to be passed to it. Hence I need to get the connection from IBATIS, where IBATIS will inturn get the connection from the configured DataSource or the connection pool, whatever it is configured to. I had done some home work to get the connection from IBATIS, but not sure whether iam doing it right. The following works when I use a SIMPLE JDBC connection pool configuration, but doesn't work when I use the datasource. Properties pCnf = new Properties(); ------------------------------ if( "direct".equals(dbCtx) ){ pCnf.put("ibatis.mapping.config","conf/sql-map-config.xml"); }else{ pCnf.put("ibatis.mapping.config","conf/sql-map-config-ds.xml"); } daoManager = DaoManagerBuilder.buildDaoManager(reader,pCnf); csafeDAO = (CsafeDAO) getDaoManager().getDao(CsafeDAO.class); ------------------------------ public Connection getConnection(){ return ( (ConnectionDaoTransaction) daoManager.getTransaction(csafeDAO) ).getConnection(); } ------------------------------ conn = getConnection(); stm = conn.createStatement(); rs = stm.executeQuery(query); // Fetch the underlying resultset from the JBoss Wrap //if the connection is from datasource if (rs instanceof org.jboss.resource.adapter.jdbc.WrappedResultSet ) { rs = ((org.jboss.resource.adapter.jdbc.WrappedResultSet) rs).getUnderlyingResultSet(); } // then cast to the OracleResultSet OracleResultSet oraRs = (OracleResultSet) rs; if(oraRs.next()){ image = (OrdImage) oraRs.getORAData("image",OrdImage.getORADataFactory()); } --------------------- If I use simple JDBC it works, but when datasource is used it throws the ClassCastException when I cast the resultset to OracleResultSet, any inputs? 06-Oct PM 5:54:02 ERROR [bl.ORDImageBO].getImageFromDB() Connection to DB failed: java.lang.ClassCastException: $Proxy64 java.lang.ClassCastException: $Proxy64 at com.bntasia.vivo.app.bl.ORDImageBO.getImageFromDB(ORDImageBO.java:254) at com.bntasia.vivo.app.bl.ORDImageBO.getImageFromDB(ORDImageBO.java:181) at com.bntasia.vivo.app.bl.ORDImageBO.getAssetTypeImageFromDB(ORDImageBO.java:1 18) -----Original Message----- From: Agilan Palani [mailto:[EMAIL PROTECTED] Sent: Thursday, October 06, 2005 10:16 PM To: user-java@ibatis.apache.org; [EMAIL PROTECTED] Subject: RE: Getting connection from ibatis Importance: High Thanks, but, do you have any answer to get the connection directly?
