我想在Eclipse中使用Servlet进行开发,但它说javax.servlet无法解析包.如何将javax.servlet包添加到Eclipse项目中？

我在jsp页面中看到以下错误 -

javax.servlet.jsp.PageContext cannot be resolved to a type
javax.servlet.jsp.JspException cannot be resolved to a type

我看过一篇关于此的帖子,并尝试了一些建议的事情.BalusC提供了很好的输入 - JSTL1.2和Standard.jar不能一起使用.我做了这个,它解决了一段时间的问题 - 但它再次出现.我不确定我是否还有罐头碰撞.我已经将所有jar定义为Maven中的依赖项.以下是我指定pom.xml的依赖项 -

这是我在尝试运行JSP文件时在浏览器屏幕上看到的内容.

对于JspFactory类型,方法getJspApplicationContext(ServletContext)是未定义的

堆栈跟踪:

org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:92)org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:330)org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler. java:439)org.apache.jasper.compiler.Compiler.compile(Compiler.java:334)org.apache.jasper.compiler.Compiler.compile(Compiler.java:312)org.apache.jasper.compiler.Compiler. compile(Compiler.java:299)org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:586)org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317)org.apache.jasper.servlet. JspServlet.serviceJspFile(JspServlet.java:342)org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267)javax.servlet.http.HttpServlet.service(httpServlet.java:856)

当我运行它时,在Tomcat窗口上抛出了jasper异常.

我正面临着这里描述的问题.我找到了一个依赖jsp-api.jar,实际上来自对Joda-Time的依赖:

<dependency>
    <groupId>joda-time</groupId>
    <artifactId>joda-time-jsptags</artifactId>
    <version>1.0.1</version>
    <exclusions>
        <exclusion>
            <artifactId>jsp-api</artifactId>
            <groupId>javax.servlet</groupId>
        </exclusion>
    </exclusions>
</dependency>

我试图排除它(见上文),但应用程序将无法编译.我怎样才能确保jsp-api没有发货.war？
