我收到以下错误:

INFO:validateJarFile(C:\ dev\server\tomcat6\webapps Sempedia\WEB-INF\lib\servlet-api.jar) - jar未加载.参见Servlet Spec 2.3,sectoin 9.7.2.违规类:javax/servlet/Servlet.class

那里的现有资源说它是由于与servlet.jar的冲突或在我的情况下命名为servlet-api.jar文件.我已经从/ webapps文件夹中删除了所有其他项目,我已经获取了tomcat6/lib目录中的servlet-api.jar文件,并将其添加到项目构建路径中,所以我看不到它是怎么回事仍然是一场冲突.

当我尝试运行应用程序时,我得到以下堆栈跟踪.

org.apache.jasper.JasperException:无法为JSP编译类:

生成的java文件中的第22行发生错误方法getJspApplicationContext(ServletContext)未定义类型JspFactory

堆栈跟踪:

我想升级我的webapp以使用servlet 3.0(插入2.5).我使用的是WebLogic Server版本:12.1.1.0(12c),maven,java 7_10和NetBeans 7.3.1

由于某种原因,唯一可用的servlet-api是3.0-alpha-1而不是3.0
