Camel Routing using Java DSL in Servlet without Spring
Hi Geeks,
Outline of the task:
1. I have a simple web application with index.jsp as welcome page having one
text input box and submit button, which is used to POST the parameter from
index.jsp to Servlet
2. This servlet is invoking one method routing which has CamelContext
initialization and route to different HTTP location along with POST
parameter received from index.jsp
Method: (The method routing is configured as below)
public void routing() throws Exception
{
CamelContext context = new DefaultCamelContext();
System.out.println("Routing through camel JAVA DSL");
context.addRoutes(new RouteBuilder() {
public void configure() {
from("servlet://CamelDSLServlet").
to("http://localhost:9090/RestfulDemo/rest/hello/jsonString?bridgeEndpoint=true&throwExceptionOnFailure=false");
}
});
System.out.println("Routing done");
context.start();
Thread.sleep(1000L);
context.stop();
}
This servlet I have declared as CamelHttpTransportServlet in web.xml.
Please suggest if above setup is right?
As I am trying to execute, this System.out.println statements getting
executed but no actual routing is happening.
How to redirect from CamelContext to ServletContext to refer to other URL
from above example?
Please guide.
Thanks in advance.
Manoj

Hi,
I tried to find release date for Apache Camel 2.11 but it is nowhere
mentioned.
Also the links provided on the site
<http://www.apache.org/dyn/closer.cgi/camel/apache-camel/2.11.0/apache-camel-2.11.0.zip>
is showing HTTP 404.
I tried to download the SNAPSHOT version and build using Maven but facing
difficulties.
It would be better to have SC release.
Can please help with tentative dates for the RC?
Thanks in advance,
Manoj

Hi
See this example
http://camel.apache.org/servlet-tomcat-example.html
And from Camel 2.11 onwards you can do this without Spring, or the
likes to bootstap your app

The code above is wrong as you just keep Camel running for 1 sec.
You need to bootstrap/start Camel as part of the web application.
eg the links in the top for the examples.
