BIRT引擎在Tomcat服務器運行報告時異常

Question

我有BIRT 4.2版本框架，同時從tomcat服務器運行應用程序我得到"org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report." 異常。但它通過RCP應用程序正常工作。在Tomcat的birt文件夾的根目錄中複製.rptdesign文件，然後將該jar文件複製到Tomcat webapps/birt/WEB-INF/lib /目錄中。 和MT堆棧跟蹤是

Answer 1

這似乎是根本原因：

Caused by: java.lang.OutOfMemoryError: Java heap space

考慮配置Tomcat的JVM來增加堆的大小。
