OK, thanks (this was more or less what I was trying to avoid :) ) I thought that this is possible based on the documentation:
https://camel.apache.org/components/next/kamelet-component.html " The Kamelet Component provides support for interacting with the Camel Route Template <https://camel.apache.org/manual/route-template.html> engine using Endpoint semantic. " And later it says: "Configuring components can be done with the Component DSL <https://camel.apache.org/manual/component-dsl.html>, in a configuration file (application.properties|yaml), or directly with Java code." For me, it's not really clear what 'interacting with the Camel Route Template' and 'configuring' means? Why do I need the extra initiation step in between? I thought I configure it directly by using it in a route through endpoint semantics? Are there plans to make it possible like I described in the previous post (thus without YAML)? I am already using the Java DSL and XML DSL and I don't want to use the YAML DSL as well. My goal is to define the template through the Java API and then let users write a route and call it to use only endpoint semantic. I do not know what values the user will use (that's why I parameterized them) and the user doesn't know anything about templates. I guess I could write a preprocessor, but that's a bit beyond the purpose of avoiding the current preprocessing (I have a web application and get the route configuration as JSON and then convert it to an XML route). The goal was to make this process easier :) Raymond On Mon, Jul 25, 2022 at 7:37 AM Claus Ibsen <claus.ib...@gmail.com> wrote: > Hi > > Kamelets and route templates are not 100% the same, so what you do is not > possible. > > The kamelet component (eg to("kamelet:xxx") is for kamelets, that are yaml > files with metadata and an embedded route template (flow) > https://github.com/apache/camel-kamelets > > With route templates, you need to use the java api, to add a route from a > template, and give it some id, and parameters. > And then from your route that wants to call then use direct:xxx to call the > new route. > > > > On Sun, Jul 24, 2022 at 11:19 PM ski n <raymondmees...@gmail.com> wrote: > > > Hi, > > > > I have a Camel routeTemplate like this: > > > > public class MyRouteTemplates extends RouteBuilder { > > > > @Override > > public void configure() throws Exception { > > // create a route template with the given name > > routeTemplate("myTemplate") > > // here we define the required input parameters (can have > > default values) > > .templateParameter("name") > > .templateParameter("greeting") > > .templateParameter("myPeriod", "3s") > > // here comes the route in the template > > // notice how we use {{name}} to refer to the template > > parameters > > // we can also use {{propertyName}} to refer to property > > placeholders > > .from("timer:{{name}}?period={{myPeriod}}") > > .setBody(simple("{{greeting}} ${body}")) > > .log("${body}"); > > } > > } > > > > And I like to call it from a route as a Kamelet like this: > > > > from("direct:a") > > .to("kamelet:myTemplate?someparameters") > > > > How to make "myTemplate" available to the CamelContext? > > > > > > I saw in camel-examples that is using camel-main that you can do it like > > this: > > > > Main main = new Main(); > > main.configure().addRoutesBuilder(MyRouteTemplates.class); > > > > However I am not using main, but Camel core.
