Current status:
As for now, I did come as far, as deploy is ok, and all classes seem
to exist. However my current problem is, that no injection seems to
work out:
ServiceImpl:
@EJB(mappedName = "sung/app/kylintv/product" )
private Product product;
// public void setProduct(Product product)
// {
// this.product = product;
// }
public DatabaseBuilderServiceImpl()
{}
@Override
public boolean createDefaultDatabaseEntries()
{
return product.createTestEntry();
}
When the function is called, product is NULL and therefore this error
is shown:
13:59:12,099 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].
[localhost].[/kylintv.gwt]] Exception while dispatching incoming RPC
