Connection pool problem with CR XI and JRC

31 Views

Hello,

I have a problem with some reports developed using CRXI and which are exported from java into pdf (using JRC). I have introduced a connection pool in the application, and for this i did 2 things:

- i set the JNDI Name in all reports

- i commented out these lines of code which were used to generate the connection dinamycally at runtime:

// ConnectionInfo connInfo = SmartCommon.getJDBCCredentials(contextRealPath, SmartCommon.FILE_SEPARATOR);
//		ConnectionInfos connections = new ConnectionInfos();
//		connections.add(connInfo);
//
//		String userName = connInfo.getUserName();
//		String password = connInfo.getPassword();
//		String connectString = connInfo.getAttributes().getStringValue(SmartCommon.PropertyBagKeys.CONNECTION_URL);
//		String driverName = connInfo.getAttributes().getStringValue(SmartCommon.PropertyBagKeys.DATABASE_CLASS_NAME);
//		String serverName = connInfo.getAttributes().getStringValue(SmartCommon.PropertyBagKeys.SERVER_NAME);
//		String databaseName = connInfo.getAttributes().getStringValue(SmartCommon.PropertyBagKeys.DATABASE_NAME);
//		String JNDIName = null;
//
//		/* Switch all tables on the main report and sub reports */
//		JRCHelperSample.changeDataSource(reportClientDoc, reportName, null, userName, password, connectString, driverName, JNDIName, serverName, databaseName, null);
//		reportClientDoc.getDatabaseController().logon(userName, password);

All reports work fine, except for one (who has a stored procedure, but i don't think the error comes from this), which gives the following error :

What do you think can be wrong?
