I have App Engine application with several modules. And trying to send request from one module to another. For this purpose I'm using code described here.
The problem is that next code returns only one current module.
ModulesServiceFactory.getModulesService().getModules();
And when I'm trying to get module hostname, like this
ModulesServiceFactory.getModulesService().getVersionHostname(moduleName, moduleVersion)
I'm getting exception com.google.appengine.api.labs.modules.InvalidModuleException: Given module is not known.
All modules I'm launching with command
mvn appengine:devserver
Also there is pom.xml in root folder, which describes all modules:
<?xml version="1.0" encoding="UTF-8"?>

I was programming a Discord Bot using JDA (I was using the 5.0.0-alpha.22).
Now I wanted to use the latest version due to some incompatibilities. As far as I know you only need to change the version in the .xml file but it says that the dependency could not be found.

Does anyone know a good tutorial for writing camel bundles?
Thanks,

You should use the Camel version that ServiceMix is using (ships with out of the box). ServiceMix does NOT support Camel 3.
Also I wonder suggest to look at just using Apache Karaf or alternative runtimes for Camel (Spring Boot, Quarkus, Tomcat, Standalone Camel via Camel Main) as ServiceMix is not so active anymore.
Replace your property with this:
<properties>
<camel.version>2.16.5</camel.version>
</properties>
I have a camel route fronted with a CXF Web Service consumer (from). I'm deploying in Glassfish 4.0 and this works fine when using the servlet spec 2.4. I now need to enhance the route by adding some persistence along the way which is being done with JPA. Doing this requires an upgrade to servlet spec 2.5+ (I've gone to 3.0)
When the servlet spec is changed to 2.5+ the following error occurs on deployment: java.lang.IllegalStateException: The lifecycle method [finalizeConfig] must not throw a checked exception. Most solutions to this say to remove cxf-rt-transports-http-jetty-2.7.11.jar.
When the jetty jar is removed, the deployment error becomes: java.io.IOException: Could not find destination factory for transport http://schemas.xmlsoap.org/soap/http
Solutions to this, such as CXF BusException No DestinationFactory for namespace http://cxf.apache.org/transports/http OR org.apache.cxf.BusException: No DestinationFactory was found for the namespace http://schemas.xmlsoap.org/soap/http/ say to import the cxf-servlet.xml file which then requires the inclusion of the jar cxf-rt-transports-http-2.7.11.jar (I removed this when I removed the jetty jar). Including these files then gives the following deployment error: java.io.IOException: Cannot find any registered HttpDestinationFactory from the Bus.
The solutions for this error all say to include the jar cxf-rt-transports-http-jetty-2.7.11.jar. This puts me back where I started having to remove it due to the servlet spec upgrade.
I've been able to create a small project to demonstrate this and have included the contents below. I've also tried deploying on Glassfish 4.1 and various combinations of different jar versions (CXF 3.0 excluding the 2.7 jars from camel etc) but I'm still unable to deploy the app in Glassfish.
I'm able to run this with the maven camel plugin 'mvm camel:run' (this requires de-scoping the cxf-rt-transports-http*.jar files from test. Of course this works because I'm outside the glassfish container.
Any help would be greatly appreciated.

As you are using address="http://0.0.0.0:9000/HelloWS/", not the relative path, cxf-rt-transports-http-jetty-2.7.11.jar is need. If you want to use the servlet transport you need to deploy the CXFServlet in you web.xml first, and setup the address of to be relative path, then you should be able to access the CXF endpoint there.

Based on the PlayN Getting Started wiki page I created a skeleton project (called GuiPoc) in eclipse. I managed to make the guipoc-html project compile successfully (with Google -> GWT Compile), and eventually Run as -> Web Application. I tried using mvn gae:run from the guipoc/html directory (in cygwin) as per the wiki, and got the following output:

Actual Question:
I don't understand why it's looking for the dependency in the system repository instead of the local directory. What am I doing wrong? Do I need to change something in my pom.xml files? Create a settings.xml in my C:\Users\MyName.m2 directory and set something there?

Unfortunately, Maven is not too smart about multimodule projects. A standard PlayN project (including yours) has the following module structure:
top
+- core
+- html (depends on core)
+- java (depends on core)
+- android, flash, etc.
When you are in the top directory, and you invoke Maven, it reads all of the submodule POMs and "knows" about all of them and will properly set up classpaths so that they see the appropriate classes directory when compiling and running.
But if you go into, say, the html directory and invoke Maven there, it no longer "knows" about all of the submodules. All it knows about is the html POM and when it sees a dependency for anything else (like the core module in this case) it goes through the standard dependency resolution process, which is:
Check the local Maven repository ~/.m2/repository.
Check the repositories explicitly specified in the POMs.
Check Maven Central.
When you have a situation where you want to run a command in one of your submodule projects, you have to arrange to do it from the top-level project. This is why testing from the command line involves running mvn test -P test-java or mvn test -P test-html from the top-level directory, rather than just cd-ing into the java or html directory and running mvn test.
Unfortunately, the tricks that we use to make it possible to test the Java or HTML submodule from the command line don't work with gae:run. So in this case, you have to work around Maven's limitations by first installing your project artifacts into your local Maven repository before invoking gae:run (and indeed, doing this every time you want to test using gae:run. This is accomplished like so:
cd top
mvn install
cd html
mvn gae:run
It would be great if Maven were smart enough to detect that it was being run in a submodule directory and automatically resolve sibling dependencies in the same way it would if you invoked Maven from the top-level project directory. Alas, smart is an adjective that's rarely applicable when talking about Maven.
