JSP文件過大無法編譯，後臺拋異常Generated servlet error:The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit，建議修改web.xml加入初始化參數，應該能有所改善。
問題描述
項目中使用SCE表單，字段很多，使用的控件多，造成JSP文件過大，在表單預覽時後臺拋異常The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit。

解決方案
空行的去除沒有幫助，減少引用的js會有小幫助，但在jsp本身很大的時候作用有限。建議嘗試修改應用服務器的web.xml文件（在tomcat下位於conf目錄下，在jboss下位於server\default\deploy\jbossweb.sar目錄下 ），修改如下圖所示之處，加入紅框內的初始化參數。
