上传运行该程序可以返回JSP环境的一些信息. 由于各种JSP应用服务器(例如Tomcat和JRun以及Resin等)在许多方面存在差异, 因此部分信息有中英对照. 此外, 因为Context attributes信息部分与JSP应用服务器有关, 故该部分只提供英文信息.如果运行后直接显示程序源代码, 则表示不支持JSP.-upload running the program can return to the JSP environment information. Various JSP application server (such as Tomcat, and Resin and JRun) in many respects differences, some messages are bilingual. In addition, because information Context attributes part of the JSP application server, Therefore, the only part of the information available in English. If you are running after a direct indication of program source code, then not support JSP.
