Subject [jira] [Created] (BVAL-135) Using bval-guice in OSGi
Date Wed, 04 Mar 2015 15:45:04 GMT
Florian Pirchner created BVAL-135:

             Summary: Using bval-guice in OSGi
                 Key: BVAL-135
             Project: BVal
          Issue Type: Bug
            Reporter: Florian Pirchner


tried to use bval-guice in OSGi environments. Added @org.apache.bval.guice.Validate to an
OSGi service method. But getting class loader problems.

Sample code:
public class RepositoryService implements IRepositoryService {

	@Validate(validateReturnedValue = true)
	public void addToRepository(@NotNull String name) {
		System.out.println("Called with " + name);


While the service method is invoked, the class org.apache.bval.jsr303.ClassValidator#unwrap(Class<T>
type) tries to load the class org.apache.bval.jsr303.extensions.MethodValidatorImpl. It is
contained in the same bundle, so OSGi should not have a problem loading it.

But the impl delegates the loading to ClassUtils.getClass(type.getName() + "Impl"). Since
ClassUtils is part of the bundle commons-lang3, the class can not be loaded and an Exception
is thrown.

Maybe you could change the call to ClassUtils.getClass(getClass().getClassLoader(), type.getName()
+ "Impl") and everything should be fine.

Thanks, Florian
