Thank you all for your replies.
Here's a snippet of the code:
*This is my class and my constructor. If you notice the first line of the
constructor calls the super method.*
public class ELODaoImpl extends AbstractJcrDAO<CmsELOImpl<IMetadataKey>> {
private static final String[] MIXIN_TYPES = { "mix:versionable" };
public ELODaoImpl( Session session, Jcrom jcrom ) {
super(<CmsELOImpl<IMetadataKey>> ,session , jcrom, MIXIN_TYPES);
}
My problem is that on the first parameter of super I have to send the Class
object for CmsELOImpl<IMetadada> and I don't know how.
Here's the signature of AbstractJcrDAO's constructor
public abstract class AbstractJcrDAO<T> implements JcrDAO<T> {
/**
* Constructor.
*
* @param entityClass the class handled by this DAO implementation
* @param session the current JCR session
* @param jcrom the Jcrom instance to use for object mapping
* @param mixinTypes an array of mixin types to apply to new nodes
*/
public AbstractJcrDAO( Class<T> entityClass, Session session, Jcrom
jcrom, String[] mixinTypes ) {
Thank you in advance,
Rokham
