How to use spring-loaded project with jboss 4. As far as I've found that we need to interact with java agent in order to hot swap *.class but how to use it for jboss or how to interact with jboss java-agent?

I'm using:
Wildfly 21
Java 11
I've just went through the pain of modularizing (with Java 9 modules) an Jakarta EE EAR application of mine that runs on Wildfly 21. This application has a war jar, ejb jars, utility jars (all have a module-info.java now) and other third party libraries. The whole application compiles well, without errors.
But I noticed that when I run it in Wildfly, althought it runs without problems as before when it wasn't modular, it seems that the application server is not considering that it is now a modular application and is not using the modulepath to run the application, but the classpath. So, at runtime, the modular nature of the application is being ignored.
Is there a way to instruct the application server to run the application as a modular one, using the modulepath instead of the classpath?
It's a pity that we have to be locked by application servers like Wildfly blocking us from using such an important Java feature (modules) at runtime in our applications.
While Wildfly doesn't support running modular wars, you can take a look at Piranha Cloud.
The Piranha Server itself can run in the module path and can deploy WARs in a new JPMS layer, respecting the module-info.class provided.

I am a Siemens Teamcenter Implementation consultant and have limited knowledge of JBOSS.
I have a question-related to JBOSS module dependencies.
Before asking a question, I will quickly give the background.
Background
JBoss version is EAP 6.1.0 installed in Linux.
For one of the POC in the Teamcenter application, we need to deploy the EAR file in JBOSS.
The company provided the shared JBOSS where other applications from the different departments also using the JBOSS.
JBOSS is used in domain mode.
Problem
For deploying the EAR file for Teamcenter application, I need to update the module.xml with JMX dependency. Since the JBOSS is shared by many applications of different departments, we need to get permission from each of them to restart the JBOSS. ( This restart point I want to confirm)
Question
Is it required to restart the JBOSS for module.xml update?
or
Is there another way to add the dependency in classpath without restarting the JBOSS.
If you edit the module.xml of a module that's been loaded you'll need to restart the server.
I'm attempting to upgrade our environment to Eclipse Luna w/ JBoss Tools from our current Indigo instance. Most things are sorted well enough, but I'm running into a wall when deploying our application to a JBoss server within Eclipse.
As far as I can see, the lib/ directory of the .ear file generated contains none of the transitive dependencies from maven that we would normally expect to see, and as a result the application does not deploy or run correctly on the server. For clarity, we use the 'use workspace metadata' deployment option on the JBoss server within Eclipse.
By contrast, if I right click on the relevant project within Eclipse and say Export... .ear file, the resulting .ear contains all the .jars that I'd expect inside the lib/ folder (there's over 50 of these things, so it's pretty easy to spot the difference). Subsequently dropping the .ear into the deploy directory of JBoss and starting a server manually has the application working fine.
Has anyone ever encountered this sort of issue within JBoss Tools / Luna, and if so what steps were taken to try and remediate it?
Cheers for any help.
Dave.
EDIT: For what it's worth, this is a JBoss Enterprise Application Platform 5.x server instance, and we're using JBoss EAP 5.2
I would like to use a custom version of the HSQL DB in an application that I am deploying in JBoss. However, JBoss already contains an HSQLDB.jar. The JBoss jar is being resolved by my application instead of the custom jar in my ear.
How can I use a different version of HSQL in my web application from the one that JBoss uses internally?
Can I remove the HSQLDB.jar included with JBoss without negatively impacting the Application Server?
The custom version it's just a newer version? If it's that the case than you can simply replace the jar in the Jboss lib folder. Jboss uses HSQLDB as far as I know for queue persistence.
I am learning EJB3 from last few days. I have many questions regarding EJB, application servers and deployment of EJB.
To start with, I have created one simple helloworld stateless session bean but I don't know how to deploy it on server. It has single bean class, bean interface and one servlet client. I have used eclipse to develop this project.
None of the books that I read gives step by step details about how to put EJB on server and how to access those beans.
I have JBoss 6 server and I also have Java EE budle downloaded from sun website. Does this Java EE bundle contains Glassfish server? or do I need to download it separately?
Can anyone please give me step by step details of how to put my bean and its client on server (JBoss or Java EE)?
And why do we need to include bean interface class in EJB client code? I mean either we need to keep client and bean in same package or if we keep them in seperate packages we need to import bean interfaces in client code. Am I right?
With Java EE 6, you can package your Servlet and your EJB in a WAR (either package your EJB in a JAR and put it in WEB-INF/lib or simply put all classes in WEB-INF/classes). And to deploy this WAR, copy it to:
$GLASSFISH_HOME/domains/<domain1>/autodeploy for GlassFish v3*
$JBOSS_HOME/server/default/deploy for JBoss 6
With Java EE 5, you'll have to package your code in a EAR.
And if you want to deploy your application from Eclipse (using the Eclipse WTP), you'll have to install the appropriate server adapter. For Eclipse Galileo and GlassFish (there is currently no adapter for JBoss 6 AFAIK), right-click the server view, select New > Server, click on Download additional server adapters and select the GlassFish adapter. Finish to define your new GlassFish v3 Java EE 6 server and deploy your application on it (right-click on your application then Run As > Run on Server). For Eclipse Helios and GlassFish, you can follow the link given by #VonC (manual install) or check this answer (install via the Update Site).
You need to add GlassFish to your Eclipse installation (see GlassFish plugin for Eclipse).
The full process is described here (with the latest Eclipse Helios 3.6M6)
You should export as EJB into your jboss<version>\server/default/deploy folder and then add the build path for it on the servlet's web project. You can "Run on Server" and choose an application server just like you would in any project, no need to export the WAR although if you do that, you're gonna have to re-export your WAR every time you modify your code
AFAIK there's no Eclipse plugin for JBoss 6 but Eclipse provides one for 5.1
