Hi, first of all, I'm wondering if your approach is really a good one. Wouldn't it be easier/more sensible if the agent either ignores further messages after the first one or return an error to the TestV3EnvironmentActionAgent1? If the service is removed, it may be difficult for the TestV3EnvironmentActionAgent1 to determine if the call did not succeed because the service was intentionally removed or e.g. connectivity was lost. Regardless, in the code you provided: IServiceIdentifier sid3 = ((IService)agent.getProvidedService(INotifyService1.class)).getServiceId();...

Hi! Sure, you can dynamically add and remove services at any time in the respective agent, e.g. inject internal access first: @Agent protected IInternalAccess agent; Then use one of the addService() or removeService() methods anywhere in the agent (instead of @ProvidedService): agent.addService("chatservices", new ChatServiceF1()); This also automatically updates the service registry infrastructure as needed in the background. However, given your description, I suspect there could be better solutions....

Hi Kevin, sorry I was only able to have a cursory look at your sourced but apparently you are using the getAvatars()-Method to check if the avatar was created. Generally there are two ways how the environment auto-creates avatars: The environment notices the new component or the component accesses its avatar through the getAvatar() (singular, not getAvatars()) method. The environment ensures there is only one avatar created. There is a bit of asynchronous behavior between the environment and agent...

Hi, your assumption is correct, in fact, this is the default so it ought to work: https://github.com/actoron/jadex/blob/96079a9f50f08f256bf22b136c70b12bb10eda6e/docs/guides/env/04%20Component%20Interaction.md Could you please provide a minimal example project so we can look into it? Kai

Yes, this is an alternative way which adds task during initialization. Unfortunately, I do not think we have an example of this, but basically you can add tasks to <env:object></env:object> in the <configuration></configuration> section by including lines like <env:task type="move_train"></env:task>. In general, be aware that EnvSupport is an older part of the Jadex codebase, hence the quirky API. If this does not bother you, you are, of course, free to use it. Edit: The .application.xml has an XML-Schema,...

Hi, your application.xml, which only defines the task type. The avatar/object has to actually instantiate the task using the IEnvironmentSpace.createObjectTask() method for the give space object (identified by objectid). Kai

Hi Kevin, thank you for trying Jadex. We are currently in a bit of a transition, so things may appear a bit confusing. Yes, our download page currently show version 3 of Jadex as the current one, however, we often recommend version 4 of Jadex, with the biggest remaining item being updated documentation for version 4. Version 3 is, unfortunately, not compatible with Java 11, however, version 4 should be working. Could you please elaborate on the problem you had using the combination of Jadex 4 and...

Hi, the way the scheduling works is as follows: Whenever a step is schedule (whether by scheduleStep or waitFor[Delay]), it gets added to a queue and executed in order of addition. Steps that are prevented from executing (e.g. having a delay) are only executed when they become due, but secondarily also preserve order of addition (so two waitForDelay() steps with exact the same delay should be executed in order of addition after the delay has passed. However, please note, mostly due to limitations...

Sure, this is possible, you would have to disable all transports: rootconfig.setRelayTransport(false); rootconfig.setNioTcpTransport(false); rootconfig.setTcpTransport(false); rootconfig.setSslTcpTransport(false); This will isolate the platform and it will then be unable to communicate with any other platform.

Hi Steve, in addition to disabling the Awareness (at least relay awareness), you also have to disable inter-platform communication via relays: rootconfig.setRelayTransport(false); Note that this will restrict the platforms to communicate only via direct connection (e.g. TCP connections), which may be an issue if there are firewalls,NAT routers etc. Kai

Hi, it appears like the Grizzly-based REST publishing in the current version has a bug that triggers the problem you've mentioned. We will into this. As a workaround, you can try using the Jetty-based publishing. Also, it is important to include all of the following artifacts for publishing to work: 'org.activecomponents.jadex:jadex-platform-extension-webservice:3.0.95' 'org.activecomponents.jadex:jadex-platform-extension-webservice-desktop:3.0.95' 'org.activecomponents.jadex:jadex-platform-extension-webservice-desktop-jetty:3.0.95'...
-
Hi, you don't have to deal with Grizzly directly, so "GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI)" etc. should be unnecessary. However, in your code snippet it says //config.setRsPublish(true); but it is commented out. Could you try again with that line being enabled? With kind regards Kai

Hi jobi, Declared required service (@RequireService) are not the only way to find services, you can also acquire them programmatically / dynamically using the SServiceProvider class, which contain a number of static methods to use (there are plans to move the functionality up into the required service feature in version 4). Using SServiceProvider has the disadvantage of somewhat obscuring component dependencies, but it can be useful such as in your case. In particular, you should have a look at this...

Hi Vinodh, we have found a solution for you. The problem is a classloader problem related to the following Spring Boot issue: https://github.com/spring-projects/spring-boot/issues/3316 The solution (based on your example) is as follows: Create a directory "META-INF" in src/main/resources. Add a file called "spring-devtools.properties" to that directory. Add the line "restart.include.jadexlibs=/jadex-.+.jar" to that file. This will force Spring Boot to include the Jadex .jar-files in the RestartClassLoader...

Hi jobi23, it should work as you expect it to work: Service A provided with platform scope on platform X should not be found by a global search from platform Y. Of course, if you do a global seach on on the same platform as the platform-scope provided service, it will be found. Could you provide us with a test case? If this does not work, it might be a bug. Regarding version 3.1: We do not expect significant changes on the API level / semantics, only the underlying communication layer. In practice...

Hi Sandra, once you got the OS and Java VM running on the Pi, there is nothing special about the Java on the Pi, it's just a Java VM (unlike Android), so you would export .jar file as you would for any other system. Just be sure that you include all your dependencies in the .jar file you export. Kai
