HI.
You can design an extra entity that holds new fields... and references your initial system design entity...
An example of that may be looks like:
ExtraData(id, idReferencedEntity, nameReferencedEntity, fieldType, fieldName, fieldValue)
And adicionally you may be need some extra java classes to translate it to the right java data type...

hi All,
I would like to implement dynamic field functionality for my hibernate + spring based application.
- user should be able to add additional fields (not defined during initial system design)
- fields can be added without restarting server
- preferably fields could be of specific data type (String, boolean, integer, etc). Else they could all be string and front-end layer can format it.
Additional information:
- using Hibernate 3.2 with annotations (JPA).
- dynamicComponent configuration is available only with hbm.xml (old way). We would preferably like to continue with JPA.
- our domain is quite rich, approach shouldn't be too narrow.
If you know of any concrete approaches for the same, please let me know.
thanks in advance,
have a great day !
Rajeev
