Java 找不到org.apache.jasper.runtime.TldScanner

在spring项目中，我将所有外部JAR导入WEB-INF/lib文件夹，之后我的项目停止编译。我不能再编译了。尝试编译时出现错误。我什么都试过了，但没有成功

这是我的日志：-

我尝试的是：-

 1.) there is no servet-api.jar in my WEB_INF/lib folder
 2.) Remove all spring jars from lib folder which i require to compile project.
 3.) Put jetty.jar in lib folder but not working.

尝试添加jetty的依赖项：

    <dependency>
        <groupId>org.eclipse.jetty.orbit</groupId>
        <artifactId>javax.servlet.jsp</artifactId>
        <version>2.2.0.v201112011158</version>
    </dependency>
    <dependency>
        <groupId>org.eclipse.jetty.orbit</groupId>
        <artifactId>org.apache.jasper.glassfish</artifactId>
        <version>2.2.2.v201112011158</version>
    </dependency>

为我工作。

我只是将整个lib文件夹移出项目， 然后给出罐子的参考。将所需的JAR移动到web inf/lib文件夹中，之后不会出现错误

这将修复错误。

您是否在eclipse平台下？是否尝试使用maven进行依赖关系管理？听起来像是你手动添加的JAR导致了这个错误。是的，我在eclipse下。是的，但是我知道，有很多JAR文件@KorhanOzturkcan我可以添加jar而不是在pom.xml中添加它们吗？当然，您可以像往常一样手动将jar添加到类路径中。不过，我并没有尝试将它们放在tomcat的lib目录中。我下载了第一个jar，并通过从下载文件夹中提供引用进行编译。但仍然不是working@RenuThakur你下载了什么罐子？javax.servlet-3.0.0.v201112011016.jar？@RenuThakur如果是，则just不包含该类。你需要的是。还有一件事，不要下载第一个jar，它只是javadocs。改为查找org.apache.jasper.glassfish-2.2.2.v201112011158.jar。
