Persist Code:
-----------------------------
public void insertFile(List<Fileupload> filevalues) {

try {
for (Fileupload fileupload : filevalues) {
System.out.println("-------before persist-----"+fileupload.getId());
getEntityManager().persist(fileupload);
System.out.println("persist");

}

System.out.println("-------after persist-----");
}
catch (Exception e) {
e.printStackTrace();
}
}
