删除web-inf/lib/下的jsp-api.jar和servlet-api.jar  试试

kaker

删除后仍不起作用，我的在tomcat7下也跟楼主是一样的毛病，删除web-inf/lib/下的jsp-api.jar和servlet-api.jar后依然无法解决

不好意思，问题已经解决了，我删除后没有重启tomcat；现在可以正常显示了，但是在谷歌浏览器下页面显示有问题，就是打印控件的高占据了挣个页面的1/4；另外请教下我不需要打印控件，我怎么才能把打印控件删除啊？

icssxsr

...\webapps\jor\jatoolsPrinter文件下，有个 jatoolsPrinter.cab。删除这个cab文件应该就可以去掉打印控件。
不知楼主是问的这个否？

jennifer

删除 tools\defaultviewer.jsp 里的 object标签即可，是以下加粗部分.

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>简表 5.0</title>
<OBJECT ID="_jatoolsPrinter" CLASSID="CLSID:B43D3361-D975-4BE2-87FE-057188254255" codebase="jatoolsPrinter/jatoolsPrinter.cab#version=5,0,0,0"></OBJECT><script src="js/jquery.js"></script>
<script src="js/toolsbar.js"></script>
</head>

但是我的项目中本身就要用到web-inf/lib/下的jsp-api.jar和servlet-api.jar 这两个jar，不删除能否解决报错问题。
