you can store json in character column (varchar, text). if want use json type may need use converter convert between , field type.

if want convert json data objects, can use jaxb eclipselink moxy this.

http://wiki.eclipse.org/eclipselink/examples/moxy#moxy.27s_json-binding

you write own converter this, or in eclipselink 2.6 dev stream there new json convert option.

see, http://wiki.eclipse.org/eclipselink/designdocs/406993
