Question

I have been trying to get a basic example of a servlet endpoint to work in camel. My example is based on this:http://camel.apache.org/servlet-tomcat-example.html

When I try to run this in Jetty though I get the following exception: ‘java.lang.IllegalStateException: No resource at org.apache.camel.component.servlet.CamelHttpTransportServlet/httpRegistry’

Here is my Web.xml

    <!-- Camel servlet -->
<servlet>
    <servlet-name>CamelServlet</servlet-name>
    <servlet-class>org.apache.camel.component.servlet.CamelHttpTransportServlet</servlet-class>
    <init-param>
        <param-name>matchOnUriPrefix</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Camel servlet mapping -->
<servlet-mapping>
    <servlet-name>CamelServlet</servlet-name>
    <url-pattern>/camel/*</url-pattern>
</servlet-mapping>


<!-- the listener that kick-starts Spring -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- location of spring xml files -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

And here is my applicationContext.xml:

<bean id="route" class="com.routes.smppRoute" />
<!-- the camel context -->
<camelContext xmlns="http://camel.apache.org/schema/spring" id="camel">
    <routeBuilder ref="route" />
</camelContext>

The route simple takes the input and outputs it to the console

public class smppRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
    from("servlet:///").to("stream:out");

}

}

I am pretty sure I have all the dependencies in, here is the pom.xml:

Answer 1

Can you try to change the version to 2.8.1 instead of using the 2.7-SNAPSHOT ?
I just did some test on the camel-example-servlet-tomcat in the Camel trunk, it doesn’t throw such a error.
