'/left.do'中的ServletException：java.lang.ClassNotFoundException：org.apache.jsp.WEB_002dINF.tiles.leftlogged_jsp [英] ServletException in '/left.do': java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.tiles.leftlogged_jsp

问题描述

在将ESAPI集成到登录表单后，我遇到一个渲染问题，并在成功登录后出现错误。

After integrating ESAPI into a login form I am getting a rendering issue and an error after a successful login.

浏览器中生成的错误指出：

The error generated in the browser states:

   javax.servlet.ServletException: org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: ServletException in '/left.do': java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.tiles.leftlogged_jsp

服务器的调试日志说明如下：

And the server's debug log states the following:

SEVERE: Servlet.service() for servlet [ActionServlet] in context with path [/FIXED] 
threw exception [javax.servlet.ServletException: org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: ServletException in '/left.do': java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.tiles.leftlogged_jsp] with root cause
java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.tiles.leftlogged_jsp

奇怪的是，我在整合时甚至没有碰到任何jsp页面esapi，它在手之前工作。我只修改了几个java页面，但是在成功登录后我现在得到了这个。

The weird thing is, I haven't even touched any jsp pages when integrating esapi, and it worked before hand. I've only modified a couple java pages yet I get this now after a successful login.

如果这将有所帮助，我可以包括两个错误消息。因为我没有修改leftlogged.jsp，而是一个给我的问题，我以为我会包括它，它可能是有帮助的。

There is more to both error messages I can include if it will be helpful. Since I haven't modified the leftlogged.jsp, yet it is the one giving the problems I thought I'd include it as well as it may be helpful.

有人可以向我解释什么是Eclipse不喜欢，因为现在我不知道什么我应该检查一下？

Could someone explain to me what exactly Eclipse is not liking because of right now I'm not sure what I should check out?

更新：我从代码中删除了欢迎和taglibs以外的所有内容，以便leftlogged.jsp如下所示：

UPDATE: I removed everything except the Welcome and taglibs from the code so that the leftlogged.jsp looks as follows:

Welcome ${USERNAME}!<br />

错误消息继续，没有更改。

The error message continues and didn't change any.

任何进一步的想法可能意味着什么错误？

Any further thoughts on what that could possibly mean is wrong?

推荐答案

我有同样的问题（ClassNotFound。 .. WEB_002dINF ...）
我通过删除

I had a same problem (ClassNotFound ... WEB_002dINF ...) I fix it by deleting

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
</dependency>

从我的pom.xml
