Multiple Kars Install
Hi, Karaf kar install code offers the option of installing kars without bundles being installed and started. All required kar bundles can then be installed and started together. Is this a technique the system is designed to use? Paul Fraser
Re: Karaf 5
Hi
No sure, it’s only class loader issue. I remember this issue in pure spring
boot with JDK11.
Let me check.

RE: Karaf 5
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?

Re: How to detect Feature or Kar install is complete
Hi, You can use the verify goal on the feature, you will be able to see the requirements of a feature (including required services). Is it what you mean ?

Re: Karaf 5
Hi Jaap,
First, maybe I was not clean in my presentation: Karaf 5 is still under
development and so, everything is not yet ready.
As said, I will “move” the code to Apache Karaf repo as soon as I consider I
have something clean and running.
Anyway, about your email, I will check. Today my focus is on the
OsgiApplicationManager to be Karaf 4 compliant.
I also have to improve the Karaf Config service.
By the way, you don’t need your own Main, just use the repackage with regular
provided Main (you can take a look on the K4 assembly repackage as an example).
I will create a gradle/maven plugin with repackage.
Regarding your issue, as you are running with JDK11, I guess you have to add
--add-modules java.security.jgss to avoid the NoClassDefFoundException.
Thanks anyway for your feedback, much appreciated.

RE: Karaf 5
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);
}

How to detect Feature or Kar install is complete
Hi, What methods are available to detect Feature or Kar install is complete if a system needs to wait for completion of a previous feature or kar? OpenHAB inspects the list returned from FeatureService or KarService to find if the required addon is in the list. Any other method suggestions? Paul Fraser
