Re: Need input on accessing http servlet

[David Parker]

As a work-around, you might create a class that invokes a HTTPClient or
other URL-friendly utility.

Invoke that logic in your route to retrieve data and then process it.

Hi,
You cannot use the Servlet component to connect to a third party servlet on
your server context.
The "servlet:" endpoint is only to offer a servlet interface to your camel
routes. See documentation at http://camel.apache.org/servlet.html:

So the HTTP-Component (http://camel.apache.org/http.html) or the
Jetty-Component (http://camel.apache.org/jetty.html) should do the trick.

Best regards,
Joerg

Need input on accessing http servlet

[ibrahimis]

Hi, I have created servlet which will return a JSON object. I am trying to
connect the servlet using Camel and put it in a buffer. But my servlet
didn't invoked at all and not throwing any error. I am currently in the
beginning stage on using camel. 

Please help.

I have used the following code.

package com.test.camel;

import java.io.IOException;
import java.io.OutputStream;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.RouteBuilder;

public class TestRouteBuilder extends RouteBuilder {

@Override
public void configure() throws Exception {


from("servlet:localhost:9078/ThirdPartyApplication/MaintainCases")
.setHeader("stream", constant(mystream))
.process(new Processor() {
public void process(Exchange exchange) 
throws Exception {
String contentType = 
exchange.getIn().getHeader(

Exchange.CONTENT_TYPE, String.class);
String path = 
exchange.getIn().getHeader(

Exchange.HTTP_URI, String.class);
path = 
path.substring(path.lastIndexOf("/"));


exchange.getOut().setHeader(Exchange.CONTENT_TYPE,
contentType + 
"; charset=UTF-8");

exchange.getOut().setHeader("PATH", path);

exchange.getOut().setBody("*Hello World*");
}
}).to("stream:header");


}

private OutputStream mystream = new MyOutputStream();
private StringBuilder sb = new StringBuilder();

private class MyOutputStream extends OutputStream {

public void write(int b) throws IOException {
sb.append((char) b);
}
}

}
