Hi,
I'm integrating Camel into my application, or better say, application
platform, that may run different arbitrary Camel routes for integration,
and I'd like to provide an ability for a developer who makes
applications for this platform to edit the routes during the
development. I'm already monitoring the filesystem for other artifact
edits, so If there is an API to reload an individual route taken from a
file I might use that.
I've considered to use a separate Camel standalone or as a containerized
service that I've noticed the project is encouraging now, but this would
require me to develop some protocol to interact with my platform during
its lifecycle. For Camel 2 I managed to instantiate xml snippets to
custom Processors but the API has changed and this Main load-reload
function seemed to do what I want for Camel 3.

Hi
What is your goal with this?
The reload stuff is for development and not a production app server to
"redeploy apps" or any sort of that.
The intention is that you work on a single application.
The reload is using Java APIs for "change file events" and this does not
support an ANT style way and whatnot.

I'm sorry please disregard my previous ramblings, moving the "deploy"
directory to the working directory of the java app did the "include"
trick. It worked without the "file:" prefix because it was looking into
the "target" directry which was the classpath.. My fault.
However, the additional question remains: how do I make it _reload_ what
it loaded previosly, without catching the extra *.yaml files that may be
located in the wrong directories?
I'm trying this,
Main main = new Main();
main.configure().withRoutesIncludePattern("file:deploy/**/PRIVATE/EXCHANGE/*.yaml");
main.configure().withRoutesReloadEnabled(true);
main.configure().withRoutesReloadDirectory("deploy");
main.configure().withRoutesReloadDirectoryRecursive(true);
// main.configure().withRoutesReloadPattern("**/PRIVATE/EXCHANGE/*.yaml");
// main.configure().withRoutesReloadPattern("PRIVATE/EXCHANGE/*.yaml");
main.configure().withRoutesReloadPattern("*.yaml");
main.configure().withRoutesReloadRemoveAllRoutes(true);
main.run();
but this will catch and load any .yaml file under the "deploy"
directory, event those that wasn't loaded at startup, when I touch any
of the yamls.
Any tips on reloading patterns?
Thank you!

Hi, thanks but this

Netbeans uses the following command to run the program:
cd /home/fedd/NetBeansProjects/camelmaintry;
JAVA_HOME=/home/fedd/Programs/graalvm-ce-java19-22.3.0
/snap/netbeans/76/netbeans/java/maven/bin/mvn -Dexec.vmArgs=
"-Dexec.args=${exec.vmArgs} -classpath %classpath ${exec.mainClass}
${exec.appArgs}" -Dexec.appArgs=
-Dexec.mainClass=camelmaintry.CamelMainTry
-Dexec.executable=/home/fedd/Programs/graalvm-ce-java19-22.3.0/bin/java
org.codehaus.mojo:exec-maven-plugin:3.1.0:exec
(nothing special in the "exec.mainClass" and other placeholders there)
I can't grasp how to make it look into this pattern:
deploy/**/PRIVATE/EXCHANGE/*.yaml
Thanks!

Hi
Okay for file system, you should favour prefixing with file:
main.configure().withRoutesIncludePattern("file:deploy/customer/PRIVATE/EXCHANGE/*.yaml");

Hi,
I'm trying to load the routes from the file system directly, it's Camel
3.20.4, and it's java 19 from the GraalVM distribution running on
Ubuntu
22.04. The fact it sees the file when no wildcard is present tells me
that I'm missing something in the wildcards and the docs.
Thank you!

Hi
Are you loading these files from classpath or file system directly.
And what Camel version do you use

Hello,
in my little test I'm trying the following,
public class CamelMainTry {
public static void main(String[] args) throws Exception {
Main main = new Main();
// this works but I need to catch more
//
main.configure().withRoutesIncludePattern("deploy/customer/PRIVATE/EXCHANGE/*.yaml");
// these don't work:'
//
main.configure().withRoutesIncludePattern("deploy/**/PRIVATE/EXCHANGE/*.yaml");
main.configure().withRoutesIncludePattern("deploy/*/PRIVATE/EXCHANGE/*.yaml");
main.run();
}
}
my files are located:
deploy/customer/PRIVATE/EXCHANGE/cust.yaml
deploy/register/bank/PRIVATE/EXCHANGE/reg.yaml
So there could be more directories in the middle; however it doesn't
substitute even one.
The Ant-style (or what I'm thinking the Ant style) pattern doesn't
seem
to catch multiple directories. If I specify the directory
explicitly it
works, but I need it to locate the routes in dozens of directories.
How do I fix it?
(While we're at it I would also like to make it reload on the fly for
the testing purposes, not all of the .yaml files but restricting
it to
my directory structure)
Thanks!
