提问by DJ-
I read through plenty of posts related to this issue but couldn't get any help .
我阅读了大量与此问题相关的帖子，但没有得到任何帮助。
ERROR Appreciate if someone can help me out.
错误感谢有人可以帮助我。
This is how my POM and web looks like . I have tried copying the required war file to C:\appache tomcat 7 but no luck. Even deploying it within the eclipse also gives me the same error.
这就是我的 POM 和 web 的样子。我曾尝试将所需的War文件复制到 C:\appache tomcat 7，但没有成功。即使在 eclipse 中部署它也会给我同样的错误。

By the exception, it looks like the com.sun.jersey.spi.container.servlet.ServletContainerclass is not available in your classpath.
作为例外，看起来com.sun.jersey.spi.container.servlet.ServletContainer该类在您的类路径中不可用。
Note that Jersey 1.xand Jersey 2.xuse different package names:
请注意Jersey 1.x和Jersey 2.x使用不同的包名称：
- Jersey 1.x:
com.sun.jersey - Jersey 2.x:
org.glassfish.jersey
- 球衣 1.x：
com.sun.jersey - 泽西岛 2.x：
org.glassfish.jersey
So, I understand you are using Jersey 1.x.
所以，我知道您正在使用Jersey 1.x。
Jersey 1.x depencency
Jersey 1.x 依赖
To use Jersey 1.x, you need the following dependecy in your pom.xml:
要使用Jersey 1.x，您需要在您的以下依赖项pom.xml：
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.19</version>
</dependency>
To read more about Jersey 1.x dependencies, have a look at the documentation.
要阅读有关 Jersey 1.x 依赖项的更多信息，请查看文档。
You can check the latest version of the jersey-serverartifactIdin the Maven Repository.
您可以jersey-serverartifactId在Maven Repository 中查看最新版本的。
Jersey 2.x depencency
Jersey 2.x 依赖
If you want to use Jersey 2.x, you have to add the following dependency to your pom.xml:
如果要使用Jersey 2.x，则必须将以下依赖项添加到您的pom.xml:
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<!-- if your container implements Servlet API older than 3.0,
use "jersey-container-servlet-core" -->
<artifactId>jersey-container-servlet</artifactId>
<version>2.22.1</version>
</dependency>
You can check the latest version of the jersey-container-servletartifactIdin the Maven Repository.
您可以jersey-container-servletartifactId在Maven Repository 中查看最新版本的。
Read more about Jersey 2.x dependencies in the documentation.
在文档中阅读有关 Jersey 2.x 依赖项的更多信息。
UPDATE
更新
If you can, I do recommend using Jersey 2.xrather than Jersey 1.x.
如果可以，我建议您使用Jersey 2.x而不是Jersey 1.x。
To do it, use the following pom.xml:
为此，请使用以下命令pom.xml：
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And the following web.xml:
以及以下内容web.xml：
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
</web-app>

If you are trying to make a Web application to provide web service using Jersey library in Tomcat and Eclipse and still getting problem after adding jersey-server.jar in the classpath. You can follow these steps to add dependency on deployment assembly.
如果您尝试使用 Tomcat 和 Eclipse 中的 Jersey 库制作 Web 应用程序以提供 Web 服务，并且在类路径中添加 jersey-server.jar 后仍然遇到问题。您可以按照以下步骤添加对部署程序集的依赖。
Project -> properties -> development assembly -> add -> java build path entries -> maven dependency
项目->属性->开发程序集->添加->java构建路径条目->maven依赖
This should work.
这应该有效。
