Can anyone help me ?
Answer
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.
