I have a class with its key of type Long
when i using jdo query to select the key and want to detach a copy, an error
occur that Long is not persistable.
The class "The class "java.lang.Long" is not persistable. This means that
it either hasnt been enhanced, or that the enhanced version of the file is not
in the CLASSPATH (or is hidden by an unenhanced version), or the
Meta-Data/annotations for the class are not found." is not persistable. This
means that it either hasnt been enhanced, or that the enhanced version of the
file is not in the CLASSPATH (or is hidden by an unenhanced version), or the
Meta-Data for the class is not found.
Is anyone has some idea?
