是什么的错误呢?不明白哦

解决方案 »

  1.   

    org.apache.jasper.JasperException: An exception occurred processing JSP page /index.jsp at line 5<c:set value="${fun:getSysArgument('head_merchant','col_sysargument','webName_cn').objectMap}" var="webName"/>javax.el.ELException: Problems calling function 'fun:getSysArgument'java.lang.NullPointerException标签没配对吧？？自己这标签怎么配的仔细检查检查
      

  2.   

    是js的function没配出来,有人知道吗?
      

  3.   

    net.xinshi.isone.modules.sysargument.SysArgumentUtil.getSysArgument(SysArgumentUtil.java:102)空指针异常
      

  4.   

    SysArgumentUtil.java
    102行代码处
      

  5.   

    5: <c:set value="${fun:getSysArgument('head_merchant','col_sysargument','webName_cn').objectMap}" var="webName"/>
     把第5行删了，看看还有错吗？
