Question

java web问题，请帮我看一下是怎么回事，

<Context path="/jspweb" docBase="F:\lesson\jspweb">
<Manager className="org.apache.catalina.session.PersistenManager">
debug=0 saveOnRestart="true"
maxActiveSession="-1" minIdleSwap="-1"
maxIdleSwap="-1" maxIdleBackup="-1"
<Store className="org.apache.catalina.session.FileStore" directory="f:\temp"/>
</Manager>
</Context>
我在学习session时，发现一个现象，以上代码是我计划在tomcat中的server.xml中增加内容，但是在实践中，当我把以代码加进去后，tomcat就不能重新启动，把以上内容删除后，tomcat就可以重新启动。请问这是怎么回事？

我的这个可以启动，复制一下应该你的也可以了

<Context path="/jspweb" docBase="F:\lesson\jspweb">
确定 你 的 项目 的 webroot 是在 F:\lesson\jspweb ？

Answer 3

你这个是设置虚拟路径还是设置什么？
