Can anyone help me ?

Answer 1

Solution:

Only add the dependency in pom.xml:

 <dependency>       <groupId>com.sun.jersey</groupId>       <artifactId>jersey-servlet</artifactId>       <version>1.13</version>  </dependency> 

Now your application will have the class com.sun.jersey.spi.container.servlet.ServletContainer

ps: Remember to check if the libraries are being sent to the tomcat deploy.

To check:

Right-click on your project -> Properties -> Deployment Assembler and make sure the Source tab contains Maven Dependecies.

Otherwise:

Click on button Add -> Java Build Path -> Maven Dependecies -> Finish.

Ready whenever you run the application all the libs will be imported in the deploy.

ps: Where the Maven project is updated, you must remake these steps.
