Red Hat Fuse Quickstart app "Content Based Router - Java DSL" does not create "work" folder

Problem

Red Hat Fuse Quickstart app "Content Based Router - Java DSL" template does not work. i.e., when built, run and deployed (to "Red Hat Fuse 7.1") the "work" folder is never created.

Here is the Java code:

package com.mycompany.camel;

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        from("file:work/cbr/input")  //<== "work" folder not created...
            .log("Receiving order ${file:name}")
            .choice()
                .when().xpath("//order/customer/country[text() = 'UK']")
                    .log("Sending order ${file:name} to the UK")
                    .to("file:work/cbr/output/uk")
                .when().xpath("//order/customer/country[text() = 'US']")
                    .log("Sending order ${file:name} to the US")
                    .to("file:work/cbr/output/us")
                .otherwise()
                    .log("Sending order ${file:name} to another country")
                    .to("file:work/cbr/output/others")
            .log("Done processing ${file:name}");
    }

}

Note that the "Content Based Router - Blueprint DSL" does work (i.e., it uses blueprint.xml file to define route, rather than Java code).

I'm using the "quickstart" template found in "Red Hat Developer Studio".

i.e. File-->New-->Fuse Integration Project-->[create project name]-->choose "Standalone" platform, choose "Karaf/Fuse on Karaf"--> under "Beginner" choose "Content Based Router - Java DSL" --> Finish--> etc.

Built and hot deployed. The Java DSL quickstart project starts and runs - but, it stops short of creating the parent "work" folder (much less the other subfolders).

What might be missing from the template project and/or configuration?

I am wondering: Is Java DSL going by the wayside in favor of Spring DSL and/or Blueprint DSL? (I had used Java DSL with old Jboss Fuse 6.3 and liked it).

Red Hat Developer Studio, Version: 12.9.0.GA

fuse-karaf-7.1.0.fuse-710023-redhat-00001

jdk1.8.0_121

C:\apache-maven-3.6.0

Using Quickstart projects are referred to in Red Hat Fuse Tooling User Guide - PDF

Solution

I did the following steps to make it work with Fuse runtime:

create a new Fuse Integration Project - Standalone, Karaf / Fuse on Karaf, CBR - Java DSL
create a new folders and file "src/main/resources/OSGI-INF/blueprint/blueprint.xml
blueprint.xml file content:

<?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd"> <bean class="com.mycompany.camel.CamelRoute" id="myRouteBuilder"/> <camelContext id="cbr-example-context" xmlns="http://camel.apache.org/schema/blueprint"> <routeBuilder ref="myRouteBuilder"/> </camelContext> </blueprint>

deploy the project via Servers view in Red Hat Developer Studio

Because the file is in the OSGI-INF/blueprint directory inside our JAR, it will be automatically activated as soon as the bundle is installed. This is possible because Red Hat Fuse uses Apache Karaf with Blueprint deployer - see Deploying into Apache Karaf - OSGi Services

Anyway, provided templates should work out-of-the-box. Therefore I raised an issue for the developers of Fuse Tooling - https://issues.jboss.org/browse/FUSETOOLS-3178
