javaweb的项目，公司买的框架，现在项目下所有的jsp都报错Unable to compile class for JSP，求大神解惑

遇到异常，求大神解惑：
本地环境里，java或者别的都是没问题的，只有jsp不能运行。环境是从别人那里copy过来的，别人那里是正常的，外部jar也都导入了。
以下面的页面为例，项目中这个页面运行正常，里面的包也已正常导入：<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<jsp:useBean id="subCompanyComInfo" class="weaver.hrm.company.SubCompanyComInfo" scope="page" />
<jsp:useBean id="departmentComInfo" class="weaver.hrm.company.DepartmentComInfo"></jsp:useBean>
<jsp:useBean id="jobTitlesComInfo" class="weaver.hrm.job.JobTitlesComInfo"></jsp:useBean>
<jsp:useBean id="resourceComInfo" class="weaver.hrm.resource.ResourceComInfo"></jsp:useBean>

解决方案 »

  1.   

    嗯，你提到：jar包都引入了，环境也配置好了。如果是tomcat发布的， tomcat版本和项目运行的jdk版本是多少呢？ 如果不对应也是不行的。
    还有检查下 项目引入的jdk版本 和 编译版本。
      

  2.   

    这个问题就是jdk版本、tomcat版本不一致导致的，参考https://www.cnblogs.com/ygj0930/p/6383192.html
    https://blog.csdn.net/levae1024/article/details/80764218
      

  3.   

    JDK=1.8 , tomcat试过7、8、9七八个版本
      

  4.   


    并没有用maven管理……
    jdk跟服务器一个版本，项目使用的是resin3.1，我试过tomcat789
    引入的servlet-api包等也删掉了
    使用maven建立过项目了，还是不行
      

  5.   

    你是直接把项目扔到tomcat里启动还是导入到开发工具里启动？ 如果是开发工具你检查下是不是没有配置全，比如用IDEA，有好几个地方控制JDK版本，你得配置统一才能正常运行
      

  6.   

    eclipse的开发环境，网上说是包依赖冲突，但是jar是直接从别人那里考过来的，并没有改动过。eclipse的jdk也都检查过了，跟别人的环境也是一样的啊，这是什么情况
