Re: Using CamelHttpTransportServlet

Hey Willem,

I'm using Camel 2.6 (we cannot upgrade from Java 5) and I'm having issues
with the Servlet component.
I'm getting the following exception:

2012-jun-04 10:53:26 org.springframework.web.context.ContextLoader

ALLVARLIG: Context initialization failed

	.....

I'm using the standard conf in web.xml

	<servlet>
		<servlet-name>CamelServlet</servlet-name>
	
<servlet-class>org.apache.camel.component.servlet.CamelHttpTransportServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>CamelServlet</servlet-name>
		<url-pattern>/s/*</url-pattern>
	</servlet-mapping>

	<context-param>
		<param-name>contextConfigLocation</param-name>
	
<param-value>classpath:/META-INF/spring/applicationContext.xml</param-value>
	</context-param>

	<listener>
	 
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>


Do you have an idea what could have gone wrong?
**Note:A CXF servlet is also configured in the same web.xml and works fine
when I remove the CamelServlet.
**Note:My project is a regular Eclipse web app targeting WebLogic that I
tested Tomcat.

Rgds,
Dominique.

Re: Using CamelHttpTransportServlet

Posted by domiko <do...@gmail.com>.
Hey Willem,

I've used a Spring DispatcherServlet to load the context specifying the
appropriate load-on-startup order.
Good news:
My CamelServlet now works and my CamelContext loads fine
Bad news:
My CXFServlet for SOAP services doesn't work anymore, it thinks it's loaded
outside an ApplicationContext.

Back porting camel-servlet 2.7 sounds daunting (for me at least) but it
seems it's my only option (unless there is another way to get HTTP requests
i.e. force usage of SOAP).
I'll keep you posted.

Thanks and regards,
Dominique.

As you are using Spring to load the configure, it cann't tell if the 
camel transport servlet is started or not If you are using camel 2.6.0.
I'm afraid you need to upgrade the camel version, or just back port the 
camel-servlet part to camel 2.6.0.
