You can have more control over the generated sequence by implementing it like this:

@Id
@GeneratedValue(generator="YourGeneratorName")
@GenericGenerator(
        name="YourGeneratorName", strategy="seqhilo",
        parameters={
                @Parameter(name="max_lo", value="1"),
                @Parameter(name="sequence", value="seq_name_of_the_sequence")
            }
)
private Long id;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;

Then, put this in front of your sequence field:

@GeneratedValue(strategy=GenerationType.SEQUENCE)

hope that was of any help...
