The cmp-field-mapping element associates a field with one or more columns to which it maps. The column can be from a bean’s primary table or any defined secondary table. If a field is mapped to multiple columns, the column listed first in this element is used as a source for getting the value from the database. The columns are updated in the order they appear. There is one cmp-field-mapping element for each cmp-field element defined in the ejb-jar.xml file.
The following table describes subelements for the cmp-field-mapping element.
