Hi Trying to write a simple rest webservice. And following the tutorial below:
http://www.tutorialspoint.com/restful/index.htm
But i am getting
HTTP Status 500 - Error instantiating servlet class org.glassfish.jersey.servlet.ServletContainer
Exception:

I was just not placing the jars in proper way. Instead of placing the required jar in webapps\MyRestPrjct\WEB-INF\lib, I was placing it in webapps\MyRestPrjct\WEB-INF\lib\libs.
It is working fine after I the moved the jars from libs to lib.
Placing all the jars in WEB-INF/lib folder resolved the issue for me.
i too faced similar issue when i did the same tutorial, the problem i found out was the servelt class specified in the web.xml is
org.glassfish.jersey.servlet.ServletContainer
but when i checked in the jars there is no package in the libraries with the above path so i change it to the existing one
com.sun.jersey.spi.container.servlet.ServletContainer
and it solved the issue.
I too got the same exception when trying to run the same module from tutorialspoint. All I did is to download the below jars and added to project. It worked fine.
jersey-common-2.0-m03.jar
jersey-server-2.0-m03.jar
jersey-container-servlet-core-2.28.jar
In my case worked by adding maven dependencies in deployment assembly.(For Maven Project*)
Right click project name (in eclipse) > configure build path > Deployment Assembly (in Left bar) > Add > java build Path Entries > Maven Dependencies > Finish

Please help I am doing this in eclipse jee mars and tried several options but could not execute it.I have attached all code. plz help.
If you changed the url mapping of a servlet in your web.xml file during runtime of the server, (depending on your server) it will not pick up on the changes. Try cleaning, rebuilding and restarting the server.
I have a simple jersey based REST Web service where i'm trying to do a test GET run..
Using Jersey 2.7 & Servlet 3.0 container, I have tried configuring the application using the jersey doc ( JAX-RS application without an Application subclass
I have defined a resource
#Path("/bolt")
public class SpringRequestResource extends BaseResource {
#GET
#Produces("text/plain")
public String getHello() {
return "Hello World!";
}
And my deployment descriptor web.xml as
<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

</servlet>
<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>

</servlet-mapping>

However, upon throwing a GET request via browser through a url http://myName.xyz.com:6080/[projectName]/myService/bolt
It throws the following exception -

Can't seem to figure out the problem here.
I cannot reproduce the issue with Jersey 2.9. You can try to migrate to Jersey 2.9. If it does not help you can create an new issue in https://java.net/jira/browse/JERSEY as this is probably a bug and not your fault. It would be good if you could attach a simple reproducible test case (simple executable maven project that reproduces the problem).
The workaround would be to use extension of Application class or ResourceConfig to configure the application.
I just made my first REST api based on this http://www.vogella.com/articles/REST/article.html
I am using eclipse kepler, tomcat7, and Jersey
when I try to "Run on server" I get this error:

You are getting
com.sun.jersey.spi.container.servlet.ServletContainer
That means you are using different version of jar. You added jersey-server.jar this jar is upgrade to jersey-servlet-1.17.jar.
So add jersey-servlet-1.17.jar to your project.
We get this error because of build path issue. You should add "Server Runtime" libraries in Build Path.
"java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer"
Please follow below steps to resolve class not found exception.
Right click on project --> Build Path --> Java Build Path --> Add Library --> Server Runtime --> Apache Tomcat v7.0
Thanks,
Sachin G N
You need to add the following jar files to your web-inf/lib folder, also you need to configure build path -- Right click your project--Build path -- configure build path -- libraries -- add external jars (add all the below jar files). And restart server
I've read through a number of posts, but just can't seem to solve my problem. You'll also see tons of posts very similar to this one, even the same tutorial. Even following them, I can't seem to get to the answer.
Essentially, I'm trying to follow the simple tutorial at: http://www.vogella.com/articles/REST/
I've made a few changes to make it compatible with Jersey 2.x
I'm using:
Eclipse
Tomcat 6 (Deployed/Run as within Eclipse)
jaxrs-ri-2.0
I've enabled the JAX-RS Facet in Eclipse
Everything builds fine
Tomcat starts fine within Eclipse
I can get to a static page content via:
http://localhost:8080/RestTEST2/index.html
However, when I try to access my service via:
http://localhost:8080/RestTEST2/jaxrs/hello
I receive a 404 with "message not found" and "The requested resource (Not Found) is not available."
Here is my web.xml which is located at /WebContent/WEB-INF/web.xml

import javax.ws.rs.core.MediaType;
// Plain old Java Object it does not extend as class or implements

public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}
I also have a JAX-RS User Library configured and referenced that includes all the JAX-RS jars.
Thoughts on what would cause the web service to not be found?
Jersey 2.0 does not recognize init-param with name com.sun.jersey.config.property.packages (web.xml). Try to change it to jersey.config.server.provider.packages as described in ServerProperties.PROVIDER_PACKAGES.
UPDATE (2020): try this link for current apidocs ServerProperties.PROVIDER_PACKAGES:
Thanks a lot.. i've been fighting for it as well.
This combination worked for me:
Tomcat 7.0.55
Eclipse Luna
Java 1.6
Jersey 1.7

I would like to add one answer in this post.I was struggling with same problem for two days and couldn't find the solution.
I tried all the possible solutions provided here but later on I realized that server was giving error of
org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException
This link answers gives the solution if somebody is stuck like me..
org.glassfish.jersey.servlet.ServletContainer ClassNotFoundException
Actually first answer given in this post suggest the solution which is for jersey 2.x bundle and if you are using jersey 1.x then it will keep on giving error.
Kindly refer to link given in answer for further reference
Simply by modifying the configuration of Apache Tomcat v7.0 while creating Dynamic Web Project, to include REST, I solved my problem. It is not enabled by default.
Recently I found myself stuck in this problem. I have got it resolved by following these two points as the solution:
By making the src/main/java as the source directory, and keeping the Project Structure as shown below:
Changing com.sun.jersey.config.property.packages to jersey.config.server.provider.packages in the web.xml
I am trying to build a website using JBoss 7.1.1 and RESTeasy. I have managed to constructed and deploy and EAR with a both a WAR and an EJB-JAR contained within:
voyager-app.ear
META-INF/MANIFEST.MF
META-INF/application.xml
META-INF/jboss-app.xml
lib/voyager-lib.jar
voyager-adm.war
voyager-ejb.jar
voyager-web.war
So far things are very simple. voyager-adm.war & voyager-lib.jar are empty (just the manifest file) but I know that I'm going to have code for them shortly. There is just one Stateful EJB - HarbourMasterBean (with just a local interface) and a few Database Entity Beans in the EJB jar file:
voyager-ejb.jar
META-INF/MANIFEST.MF
META-INF/persistence.xml
com/nutrastat/voyager/db/HarbourMasterBean.class
com/nutrastat/voyager/db/HarbourMasterLocal.class
com/nutrastat/voyager/db/PortEntity.class
com/nutrastat/voyager/db/ShipEntity.class
As far as I can tell the EJBs deploy correctly because the database units are created and the log shows that the publication of some HarbourMaster references:
java:global/voyager-app/voyager-ejb/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal
java:app/voyager-ejb/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal
java:module/harbour-master!com.nutrastat.voyager.db.HarbourMasterLocal
java:global/voyager-app/voyager-ejb/harbour-master
java:app/voyager-ejb/harbour-master
java:module/harbour-master
The problem lies in getting the HarbourMaster EJB injected into my web bean. The reference to it is alway NULL no matter what I try.
voyager-web.war
META-INF/MANIFEST.MF
WEB-INF/web.xml
WEB-INF/classes/com/nutrastat/voyager/web/
WEB-INF/classes/com/nutrastat/voyager/web/Ships.class
WEB-INF/classes/com/nutrastat/voyager/web/VoyagerApplication.class
Ships.java:
#Path("fleet")
public class Ships {
protected transient final Logger log;
#EJB
private HarbourMasterLocal harbourMaster;
public Ships() {
log = LoggerFactory.getLogger(getClass());
}
#GET
#Path("ships")
#Produces({"text/plain"})
public String listShips() {
if (log.isDebugEnabled())
log.debug("Harbour master value: " + harbourMaster);
return "Harbour Master: " + harbourMaster;
}
}

I have been searching the web for an answer and read a number of places, both on StackOverflow and elsewhere that suggests is can be done, and that the problems lies with configuration. But they post only snippets and I'm never sure if I'm doing things correctly.
Many thanks for any help you can provide.

What happens if you do:
#Path("fleet")
#Singleton
public class Ships {
