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)....

Any hints or pointers on what might be missing from the template project and/or configuration?

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... --hoped to use it again)

Thanks for any help! :-)

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

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

1. create a new Fuse Integration Project - Standalone, Karaf / Fuse on Karaf, CBR - Java DSL


2. create a new folders and file "src/main/resources/OSGI-INF/blueprint/blueprint.xml
   


3. 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>


4. 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

Check the folder permissions for C: and also use the uri as mentioned below:

from("file://C:/AAAInput/?autoCreate=true&noop=true")

Looks like your route didn't start at all. Try to use direct ref to route builder instead of package scan like this:

<camel:camelContext id="aaa.bbb.ccc.jar" xmlns="http://camel.apache.org/schema/blueprint">

    <camel:routeBuilder ref="routeBuilder"/>

</camel:camelContext>

<bean id="routeBuilder" class="aaa.bbb.ccc.jar.CamelRoute" />
