我不知道在“网页”和“WEB-INF”文件夹下给出哪个路径..

我试图在WEB-INF下给出路径“tomcat/webapps/roots/WEB-INF”

在源代码下，我给出了保存在 nutch1.4 源文件夹中的“src”文件夹的路径...

而对于lib，给出的路径是nutch1.4 bin文件夹下的“lib”文件夹......

构建成功但是当我运行它时......它显示以下异常！

javax.servlet.ServletException: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()   [Lorg/eclipse/jdt/core/compiler/IProblem;

 org.apache.jasper.servlet.JspServlet.service(JspServlet.java:272)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)

根本原因在哪里
