Karaf 5

[jgfrm <fr...@gordijn.org>]

Hi,

I have two questions about Karaf 5:
- is the presentation by Onofre at ApacheConf online somewhere?
- is it possible to explore Karaf 5 (or: what is there right now)? I am in
particular interested in the Spring Boot functionality, as I have a Spring
Boot application that I want to port to Karaf to support dynamic loading of
components. I have found the github repo of Onofre, but it is unclear to me
how e.g. to start Karaf.

Best,

-- Jaap

Hi Jaap,

RE: Karaf 5

Hi JB,

That sounds interesting!
Is it possible to share what you developed?

Best,

|Hi Jaap,
|
|so, yes, we are talking about the same thing ;)
|
|There are actually two parts:
|
|- registering Spring bean in the K5 service registry and use it in another apps
|running in K5
|- registering "generic" services (like the json-config-loader, extractor, etc) that
|provide shared resources (like HTTP handler)
|
|Regards

Re: Karaf 5

[Jean-Baptiste Onofré <jb...@nanthrax.net>]

Hi Jaap,

so, yes, we are talking about the same thing ;)

There are actually two parts:

- registering Spring bean in the K5 service registry and use it in 
another apps running in K5
- registering "generic" services (like the json-config-loader, 
extractor, etc) that provide shared resources (like HTTP handler)

Regards
JB

RE: Karaf 5

[jgfrm <fr...@gordijn.org>]

Perhaps.

I want to be able to use a bean in other Spring module.

What is also an issue it that two (or more) modules obviously result in two sockets to be opened, in my case both 8400.
A solution could be to open a different socket per module, e.g. negotiated with a module for that purpose that also routes traffic for a particular endpoint to the socket of the module handling that endpoint.

In https://github.com/hank-cp/sbp (based on pf4j) they have a different strategy; there they have one socket for REST calls, and specific endpoints are forwarded to the appropriate plugin.

Best,

-- Jaap

|I started a service bridge allowing to implicit push some spring bean to the k5

|
|Is it what you are looking for ?

Re: Karaf 5

[JB Onofré <jb...@nanthrax.net>]

I started a service bridge allowing to implicit push some spring bean to the k5 registry and so that can be used from other modules running in k5. It’s a local branch for now but I can push it on main. 

Is it what you are looking for ?

Regards 
JB

Re: Karaf 5

[Jean-Baptiste Onofré <jb...@nanthrax.net>]

Thanks for the update.

I'm happy to say you are the first one to "use/launch" Karaf 5 ;)

About the TomcatURLStreamHandlerFactory is known "issue":

https://github.com/jbonofre/karaf5/blob/main/services/spring-boot-application-manager/src/main/java/org/apache/karaf/springboot/SpringBootApplicationManagerService.java#L110

I have to improve this ;)

Regards
JB

RE: Karaf 5

[jgfrm <fr...@gordijn.org>]

The following works:

Karaf.json:
====
{
  "applications": [
    {
      "name": "e3web",
      "url": "file:///home/jaap/Karaf5Test/e3web-dev.jar",
      "type": "spring-boot",
      "properties": {
        "enableHttp": true,
        "enablePrometheus": true
      }
    }
  ]
}
====

Add to Spring boot application:
====
@SpringBootApplication
@ComponentScan
public class E3webApplication {

 ...
    public static void main(String[] args) {
        TomcatURLStreamHandlerFactory.disable();  // see https://github.com/spring-projects/spring-boot/issues/21535
        SpringApplication.run(E3webApplication.class, args);
    }
====

Start with 
java --add-modules jdk.security.jgss -cp ../karaf5/assemblies/k4/target/k4-5.0-SNAPSHOT.jar:target/e3web-test-1.0-SNAPSHOT.jar:../karaf5/services/spring-boot-application-manager/target/spring-boot-application-manager-5.0-SNAPSHOT.jar -Dkaraf.config=src/main/resources/karaf.json org.apache.karaf.boot.Main

Re: Karaf 5

[JB Onofré <jb...@nanthrax.net>]

Hi

No it’s not this because k5 don’t use OSGi for the spring boot launcher. I still think it’s a missing add modules as Jvm arg. I will check today.

JB

RE: Karaf 5

[jgfrm <fr...@gordijn.org>]

Hi JB,

Fully understand that it is still work in progress.

Regarding the .NoClassDefFoundError: org/ietf/jgss/GSSException
--add-modules java.security.jgss does not solve it?
Is it a class loader problem?

Best,

-- Jaap

RE: Karaf 5

[jgfrm <fr...@gordijn.org>]

Hi Jean-Baptiste,

I managed to start (well not completely) my spring application.
However, while starting up, I get an exception:

11:43:03.148 [main] ERROR o.s.boot.SpringApplication:837 - Application run failed
org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is java.lang.NoClassDefFoundError: org/ietf/jgss/GSSException

Any ideas?

Also, I had to make modifications in SpringBootApplicationManagerService/start:

try {
            Thread.currentThread().setContextClassLoader(classLoader);
            // disable tomcat stream handler
            /* There is no TomcatURLStreamHandlerFactory in my spring jar
            final Method tomcat = classLoader.loadClass("org.apache.catalina.webresources.TomcatURLStreamHandlerFactory").getMethod("disable");
            if (!tomcat.isBridge()) {
                tomcat.setAccessible(true);
            }
            tomcat.invoke(null, null);
             */
            // invoke spring boot main
            final Method main = classLoader.loadClass("org.springframework.boot.loader.JarLauncher").getMethod("main", String[].class);
            main.setAccessible(true);
            log.info("Call JarLauncher");
            if (properties.get("args") != null) {
                log.info("Call JarLauncher with args");
                main.invoke(null, new Object[]{ properties.get("args") });
            } else {
                log.info("Call JarLauncher without args");
                main.invoke(null, new Object[]{new String[0]}); // the original invoke did not work for me
            }
        } finally {
            Thread.currentThread().setContextClassLoader(original);
        }

Further details:
