NoClassDefFoundError OSGi ServiceBuilder MVCPortlet

[Phill Pover, modificado hace 7 años.]

Hi all,

I'm struggling with trying to include an OSGi service builder module in an MVCPortlet. I've built both with Maven artifacts, and all seems to compile and install correctly, but no matter what, I get a NoClassDefFoundError when trying to create an object.

I can use the objects created in Service Builder on the script console within Liferay, so I'm pretty confident that the service builder part is working, but whenever I try to load the page with my portlet on it, it give the NoClassDefFoundError.

Excerpts of code, if it helps:

@Override
	public void doView(RenderRequest request, RenderResponse response)
		throws PortletException, IOException {
		
		...
			
			Subscription s = getSubscriptionLocalService().createSubscription((long) 1);
			s.setName("test subscription");
			s.isNew();
			getSubscriptionLocalService().addSubscription(s);
                ...
                }

@Reference
	private volatile SubscriptionLocalService _subscriptionLocalService;
	
	public SubscriptionLocalService getSubscriptionLocalService() {
		return _subscriptionLocalService;
	}

What am I missing?

Thanks,
-Phill

So I’ve figured out the issue. I had a package in my portlet with the same package name as one generated by the service builder project. The dependency analyser was seeing the internal package and labelling it as private, which caused the one from service builder to be considered in the same way.

Renamed the package in my project and all is working fine now.

Thanks anyway.
