Hawtio unable to detect Camel routes when added via a JAR.

[HARSHITHARSH]

I am integrating hawtio with our spring boot app (3.2.2) with Camel 4.4.0, and we are importing a JAR in the app that also has camel routes in it, although all the routes are starting properly, in hawtio console I see a blank screen.

Removing the JAR the hawtio screen shows the routes.
To sum up:

For Example

1. If APP has 2 routes(without JAR import) : Two routes are shown in hawtio console
2. If APP has 2 routes & JAR has 2 routes : None of the routes are shown in hawtio console

Hi @HARSHITHARSH, thanks for the reporting.

I tested the same setup at my end, but couldn't reproduce the issue. Hawtio works just fine with 2 app routes & 1 route from an external jar.

I used the following route in a jar:

package com.example.hello;

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;

@Component
public class Hello extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        // Write your routes here, for example:
        from("timer:java?period={{time:1000}}")
            .setBody()
                .simple("Hello Camel from ${routeId}")
            .log("${body}");
    }
}

then using the example project springboot imported the above project com.example:hello:1.0.0 and loaded the component from the startup application as follows:

@SpringBootApplication(scanBasePackages = {"io.hawt.example.spring.boot", "com.example"})
public class SampleSpringBootService {

So, maybe it's related to the way you build the jar and import it into the main app. Can you provide us with a reproducer?

Can we try with spring dsl routes in both application and jar.

[tadayosi]

@HARSHITHARSH What does "spring dsl routes" mean? Does it mean Spring XML DSL routes?

[HARSHITHARSH]

Yes sir.

@HARSHITHARSH Tried Spring XML DSL but nothing has changed. It works.

I suspect it's related to the way you've made the JAR. Can you show us the output of the following command?

$ jar -tf <name-of-the-jar>.jar
