Donald Kwakkel commented on TOMEE-2458:
---------------------------------------
When adding above line to MyClassLoader [^myclassloader.jar.withtccl] :
{code}
package test;
import java.net.URL;
import java.net.URLClassLoader;
import org.apache.catalina.loader.WebappClassLoader;
public class MyClassLoader extends WebappClassLoader {
public MyClassLoader(ClassLoader parent) throws
java.net.MalformedURLException {
super(parent);
addURL(java.nio.file.Paths.get(System.getProperty("catalina.home"),
"myexception.jar").toUri().toURL());
org.apache.openejb.loader.SystemInstance.get().setComponent(org.apache.openejb.core.ParentClassLoaderFinder.class,
fallback -> java.lang.Thread.currentThread().getContextClassLoader());
}
private static URL[] getURLss(){
try {
return new URL[]{new
URL("file:///C:/Program%20Files/TomEE/myexception.jar")};
}
catch(Exception e) { throw new RuntimeException(e); }
}
}
{code}
and adding a bean to the myexception.jar which is loaded through this
classloader [^myexception.jar.withbean]:
{code}
package test;
import static javax.ejb.TransactionAttributeType.SUPPORTS;
import java.util.function.Supplier;
import javax.ejb.LocalBean;
import javax.ejb.Singleton;
import javax.ejb.TransactionAttribute;
import javax.xml.ws.Provider;
@Singleton(name = "PlatformContextBean")
@LocalBean
public class PlatformContextBean<T extends Supplier<?>> implements Provider<T>
{
@SuppressWarnings("unchecked")
@Override
@TransactionAttribute(SUPPORTS)
public T invoke(T request) {
Object result = request.get();
return (T) (Supplier<?>) () -> result;
}
}
{code}
I get the following exception from Micro Profile:
