I am currently workin on an Application which is able to load modules provided in other jar files by using a custom classLoader

MyModule myModule = myModuleClassLoader.loadClass(f.getPath(), 
                    moduleConfig.classpath, MyModule.class);

This works perfectly fine, the modules can use all provided methods by the core application, and they can subscribe to events. Now the issues is, that if I have two modules for example, A and B, and I load both modules, they will be loaded as intended, but when I try to access a class from module A in module B, I get a ClassNotFoundException. I don't really have an idea why this is happening, because the CoreApplication is loading both modules, and all interaction from the modules to the core application work as intended.

  • Does this answer your question? [How do I resolve ClassNotFoundException?](https://stackoverflow.com/questions/17408769/how-do-i-resolve-classnotfoundexception) – Hovercraft Full Of Eels Jul 16 '23 at 22:58
  • Did you `export` the necessary packages in the module declarations? https://www.oracle.com/corporate/features/understanding-java-9-modules.html – Jim Garrison Jul 16 '23 at 23:13

Found the solution myself. My custom ClassLoader used new UrlClassLoader() when I loaded a new Class, but you have to make sure to create One UrlClassLoader and use this one for every time when I use the loadClass method. By doing this, module A can now access the Classes from Module B an the other way arround.
