Hello everyone,

I have been using Jersey 1.0.2 with the tomcat, and everything had been working great so far. Then I switched over to using the SpringContainer from ServletContainer (replacing the <servlet class> in web.xml)
from :

com.sun.jersey.spi.container.servlet.ServletContainer

 to :

com.sun.jersey.spi.spring.container.servlet.SpringServlet

and I'm getting the following error when I start tomcat. :

Apr 7, 2009 6:14:53 PM com.sun.jersey.spi.spring.container.servlet.SpringServlet initiate
SEVERE: Exception occurred when intialization

I do not have any beans defined in my spring-applicationContext.xml, since I'm not using anything spring related yet. Here's my web.xml and spring-applicationContext.xml, for posterity.


web.xml

<web-app>
  <display-name>JSR311 Test Web Application</display-name>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring-*.xml</param-value>
  </context-param>
  <listener>
    <listener-class>
      org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>
  <servlet>
    <servlet-name>JSR311Handler</servlet-name>
    <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>JSR311Handler</servlet-name>
    <url-pattern>/api/*</url-pattern>
  </servlet-mapping>
</web-app>

spring-applicationContext.xml

My HelloWorldResource:


package com.clickbank.api;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("/test")
public class TestURL
{
    @GET
    public String testMe()
    {
        return "Hello There!";
    }
}


I'd really appreciate if somebody could help me getting this resolved. Once I can get spring working with jersey then I can start using other aspects of my projects with jersey, but this issue has been hampering my progress. I apologize if I'm doing something stupid, as I'm just getting started with jersey.

If you guys want, I can post this in the wiki - but somebody mentioned that I should first try sending to this email first.


Thanks,

Jalpesh
