Jersey REST Web Service with Tomcat, Eclipse and 404's - Need another set of eyes please - eclipse

Question

This should be so simple, but its blowing my mind... I have read through hundreds of the questions here, and so far none of the responses has made a difference in what I have tried. It is obviously time for another set of eyes..
I am getting a 404 error when trying to do the most simple of rest tests.
My Tomcat 7.0 Servers starts up just fine. No errors.
My project name in Eclipse is: atomic_services_poc
The Context in Tomcat is set to: /atomic_services_poc
I can successfully return static pages with: http://localhost:8080/atomic_services_poc/index.html
Here is my web.xml:
<servlet>
<servlet-name>workflowmanagerserlvet</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.tp.wfm.webservice</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>workflowmanagerserlvet</servlet-name>
<url-pattern>/workflowmanager/*</url-pattern>
</servlet-mapping>
Here is the java code for WorkFlowManagerRestService.java
package com.tp.wfm.webservice;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("/workflow")
public class WorkFlowManagerRestService {
#GET
#Produces(MediaType.TEXT_XML)
public String sayXMLHello()
{
return "Data Return";
}
}
I am using SoapUI to test the GET method of the restful request. I have tried numerous variations of the following and they all result in a 404 error.
GET host:8080/atomic_services_poc/workflowmanager/workflow
Help please before I throw this laptop...

Answer 1

I don't see anything wrong in your setup, from what you show. You don't mention which Jersey version you are using but I guess is bigger than 2. (I believe in Jersey < 2 the name of the property in the web.xml was different).
I would suggest the following to try to debug:
(1) For the moment remove the
#Produces(MediaType.TEXT_XML)
as suggested by #braunpet, and just test it with your web browser
(2) Add a ResourceConfig class so that you can at least debug what the server is doing in startup. This is pretty simple, you define a class like this:
package com.tp.wfm.application;
import org.glassfish.jersey.server.ResourceConfig;
public class MyApplication extends ResourceConfig {
public MyApplication() {
super();
packages("com.tp.wfm.webservice");
}
}
And change your web.xml like this:
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>com.tp.wfm.application.MyApplication</param-value>
</init-param>
Then you add a breakpoint in Eclipse to make sure your resources are loading.
I hope it helps!

Answer 2

Ok, so this morning I went back to basics. I created a brand new workspace with eclipse on my laptop from the vogella tutorial. I got this one to work on my laptop in all of 10 minutes. I then went to my problem work area and added the same items step by step. It worked...
I then started adding in my components and slowly one by one, I was able to get them working. I must have had some type of spelling or something wrong, but I feel better that no one here could see it either.
The good news it is now working. (Even after I removed the vogella stuff)..
:)
Thanks all that helped!

Answer 3

well I had the same problem. I was looking for a solution for about 2 weeks. After having passed 20 tutorials it drived me crazy why my tomcat is still showing the 404 response. I just wanted to get a helloworld-example working but the server was showing the 404 every time when I tried to open a ResourcePATH (e.g. #Path("/hello")). My Web.xml was "setupped" for jersey 2.x and the url param was declared as "/rest/*". The URL was called correctly by localhost:PORT/PROJECT/rest/hello.. but no Chance.
Finally I found a solution for myself that may help someone else who is troubling with this (like the author of this question):
Create a .WAR file of your Project and put it into your "apache_tomcat/webapps" directory
(Eclipse: Right Click on the Project-> Export-> as .WAR file)
Restart the Tomcat-Server
Run the Application on the restarted Server
After that, it worked for me, I was able to connect to any #Path("") I implemented. And if I want to implement a new #Path I have to reprocess the 3 steps. Hope this can be helpful!
