I agree with you. Most of these problems are infrastructural.

Yes, I also do agree with that.

There should be direct support for this situations, like paging, in the persistence framework we are using.

Does this really makes sense? Shouldn't be the persistence framework a small set of operations and then you would create more complex operations - such as paging - around it?

E, in the example, is not an example class, it's a generic type. So you can't even do new E().

Yes, you're totally right, it seems my brain froze while writting that part. After all generics are compile time, not run time. If on runtime there's no generics you cannot make a reference to it's class. Oh well... It ~~seemed~~ a good idea to read objects using the class.
