Restful Web Service runs in Shell but not Eclipse Juno

[James Dekker]

Hello, I am using Eclipse Juno, Jersey, Maven 2.2.1, tomcat 7, and m2eclipse plug-in.

Am able to create a war file for my Web Service using both m2eclipse and maven using the command line.

Afterwards, I have a shell script which deploys the war file from my $ProjectDir/target to $CATALINA_HOME/webapps

When I start up tomcat from the command line, everything runs well in catalina.out (console output).

However, when I run tomcat using Eclipse, it gives me this error:

INFO: Deploying web application archive /home/dev01/DevTools/apache-tomcat-7.0.32/webapps/RESTfulExample.war

My web.xml file looks like this:

<web-app id="WebApp_ID" version="2.4"
	xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>jersey-serlvet</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>
</web-app>

Inside my particular web app's WEB-INF/lib dir, I have the following files (automatically packaged by maven install):

asm-3.1.jar
jersey-core-1.15.jar
jersey-server-1.15.jar

Why do I not receive this stack trace when running tomcat from the command line but I do receive it in Eclipse?

Thank you for taking the time to read this...

Look inside the file /home/dev01/DevTools/apache-tomcat-7.0.32/webapps/RESTfulExample.war and make sure that the jersey libraries are there also. I suspect that Eclipse didn't package them...
