JSP文件过大无法编译，后台抛异常Generated servlet error:The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit，建议修改web.xml加入初始化参数，应该能有所改善。

解决方案

空行的去除没有帮助，减少引用的js会有小帮助，但在jsp本身很大的时候作用有限。建议尝试修改应用服务器的web.xml文件（在tomcat下位于conf目录下，在jboss下位于server\default\deploy\jbossweb.sar目录下 ），修改如下图所示之处，加入红框内的初始化参数。
