JDO Datanucleus: Annotator @Column(jdbcType="") not working

I noticed that this type of annotation does not work. In my example I had set:

      @Column(jdbcType="VARCHAR(5)")
      private String id;

but in the db saves me how: VARCHAR(255).

How can I fix?

Solution

You should use:

@Column(jdbcType="VARCHAR", length=5)
private String id;
