Question

设计界面时遇到的问题如下：

为了结合拖放的功能，我正在使用SWT和所有 SWT拖放类在包中定义 org.eclipse.swt.dnd。现在我的问题在于开发一个独立应用程序我已经包含了名为的外部jar swt-4.2.1-win32-win32-x86并且工作正常。但同时如果我包含该包，则开发Java EE应用程序 jsp页面中的org.eclipse.swt.dnd <%@page language="java" import="org.eclipse.swt.SWT"%>它显示以下错误：

HTTP Status 500 - Unable to compile class for JSP:
