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

Question

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

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

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

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.

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.

<br />
<a href="<c:url value="/logout.do" />">Log Out</a>

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

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

Welcome ${USERNAME}!<br />

The error message continues and didn't change any.

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

Answer 1

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>

from my pom.xml

Answer 2

Alternatively, if removing javax.servlet breaks your app and you're inheriting it from another source (a common project that your team puts shared resources in, for example), try adding

<scope>provided</scope> 

in the dependency tag for javax.servlet.
