我在java中创建了一个测验应用程序，以便在Google App Engine上托管。但是，当我尝试部署它时，它会产生无法编译JSP java类的错误。即使我尝试上传空白JSP。在本地服务器上，一切正常。 错误如下所示。
------------部署前端------------
准备部署：
在以下位置创建了临时目录： '/var/folders/2y/f99pqznd5m3g21gbjl7rgjc40000gn/T/appcfg966104224651839827.tmp'扫描jsp文件。 编译jsp文件。 com.google.appengine.tools.admin.JspCompilationException：失败 编译生成的JSP java文件。 2015年9月2日下午6:35:38 org.apache.jasper.JspC processFile INFO：内置文件：/index.jsp
可以在中找到调试信息 /private/var/folders/2y/f99pqznd5m3g21gbjl7rgjc40000gn/T/appengine-deploy2339970973769784997.log
我已经尝试过找到解决方法。但到目前为止没有成功。 JSP文件如下所示。它没有做任何事情，我仍然得到错误：

我尝试通过在Temp Directory中生成生成的Java类来解决此问题。但是，我没有看到任何错误。

最后，这是AppEngine-web.xml文件和Web.xml文件。万一它可能会派上用场。
