generic DAO giving error... why?

[Sanjit Kumar]

hi everyone,
Help me out, i got the error while writting generic dao class, saying jre5 is needed(i have jre6).
Has java 6 excluded parametrized type collection???

public interface GenericDAO<T, ID extends Serializable> {

T findById(ID id, boolean lock);
List<T> findAll();
T makePersistent(T entity);
void makeTransient(T entity);
void flush();
void clear();
}

You need 5.0 or greater for the JDK to compile and the JRE to run.

So one of those two, I am guessing is less than 5.0

Do you have any Oracle installed, they tend to want to put their stuff first in the path var, and they use a really old JRE version and it really messes with your machine.

Go to a command prompt and type

javac -version

and

java -version

What numbers do you see?
