Я настроил файлы web.xml и context.xml и скопировал файл ojdbc14.jar в папку webapps\birt\WEB-INF\platform\plugins\org.eclipse.birt.report.data.oda.jdbc_2.6.2.r262_v20110127\drivers.
После запуска отчета через браузер я получаю эту проблему.Первоначально это показывает индикатор выполнения.Но через некоторое время (30 минут) он показывает пустой отчет.
Мой запрос может занять один час.Но отчет показывает пустой с 30 минут.В чем проблема?
