| | 15 | = 如何讓 Servlet 執行 shell 或其他指令 = |
| | 16 | servlet 就是 java ，因此呼叫shell 或指令用同一個語法 |
| | 17 | {{{ |
| | 18 | #!java |
| | 19 | Runtime.getRuntime().exec( "/path/my_shell.sh"); |
| | 20 | }}} |
| | 21 | |
| | 22 | = 如何編譯 Servlet 與執行 = |
| | 23 | |
| | 24 | 需要額外引入 servlet-api.jar 與 jsp-api.jar （此兩個檔可以到 tomcat_home/lib/） |
