我制作了一个加密Web应用程序并在本地试用，效果很好。但是当我在WSO2云上尝试它时，它会给出这个异常报告：

HTTP Status 500 - PWC6033: Error in Javac compilation for JSP

message PWC6033: Error in Javac compilation for JSP

description The server encountered an internal error that prevented it from fulfilling this request.

exception

等错误，请问如何解决这些异常？
