I am trying to deploy an embedded tomcat
server and implement some jersey
web services. I managing to run the server correctly and access any other servlet except the ones handled by jersey. When I am trying to access the jersey services through the web browser I am getting the following error

Due to the initialization of the application the following is printed, indicating that jersey container has load correctly the servlets

INFO: Initiating Jersey application, version 'Jersey: 1.18.1 02/19/2014 03:28 AM'
The code I am using to register the resources
is the following
Wrapper a = Tomcat.addServlet(rootCtx, "rest", "com.sun.jersey.spi.container.servlet.ServletContainer");
a.addInitParameter("com.sun.jersey.config.property.packages","controllerModule.servlet");
a.setLoadOnStartup(1);
rootCtx.addServletMapping("/*", "rest");
Some things to take in mind
- The HelloWorldService
is the common testing servlet found in most Jersey tutorials
- It is essential to use jersey 1.18.x
and tomcat
, any other suggestion is acceptable but I cannot consider it as a solution, at least for the time being. I have seen many tutorials with alternatives e.g greater jersey version, using jetty, http-jersey-server etc
Update 03.12.2014
It seems like the problem was a dependency on my pom.xml file
I was using:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
Which I had to change to:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
</dependency>
Strangely that way the jersey Servlets works but not the other servlet I have, which extend HttpServlet
class
