Hi, I'm working on carrying out application on Oracle database to PostgreSQL. The server is weblogic. For Oracle we use XA connection but there isn't in PostgreSQL so I try to use XA emulate Connection taht allows weblogic. But I don't succeed to use it correctly. The connection seems correct, but at a time, the server uses the method getXAResource() and this method return null and an error is produced. I've checked the case "Emulate XA connection" on my weblogic server connection. When i create my connection I do, Connection cx = getPostgresqlDataSource().getConnection(); return new ManagedConnectionImpl(this, pwdCred, null, cx, false, false); and getPostgresqlDataSource is : private javax.sql.DataSource getPostgresqlDataSource() throws ResourceException { try { InitialContext initialContext = new InitialContext(); return (javax.sql.DataSource)initialContext.lookup(ADOCProperties.getKeyValue(ADOCProperties. FRAMEWORK_XA_DATASOURCE_DRIVER)); } catch (Exception e) { logger.severe(e.getMessage()); return null; } } Is somebody have an idea ?
