用spring tools suit开发一web程序,用sts自带的tomcat调试,工程结构是从一老工程考过来的,新建一jsp,报错如下:
?
java.lang.NullPointerException at org.apache.jsp.index_jsp._jspInit(index_jsp.java:22) at org.apache.jasper.runtime.HttpJspBase.init(HttpJspBase.java:52) at org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:159) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:329) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:337) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
?Google一下,原来是jsp-api.jar重复了,在WEB-INF/lib下删除之 解决。由于原有项目是正常工作的,所以此问题笔记一下,下次出现好解决。
