Nathan, The thing is, there IS a framework for what you are trying to do (i.e. represent a data structure without being tied to implementation). It's called Java. If you're looking for the ability to quickly add fields to customer's data structures, that's dependent on low coupling and

With SmartGWT you can represent a data structure as a DataSource. A DataSource can be tied to any kind of data provider - not just different JPA implementers but also WSDL web services, REST services, non-JPA persistence systems like Ibatis, etc. The persistence engine is pluggable, so you can

It apparently can be tied to a backend datasource, although all of these examples have setClientOnly(true) There are no examples that I know of actually showing a connection, for example with a sample mysql database or really anything else. Please correct me if I'm wrong. On Tue, Aug 4, 2009 at

Hi John, For live connections to SQL, Hibernate and other data providers see the SmartGWT Pro/EE showcase: http://www.smartclient.com/smartgwtee/showcase/ As well as Sanjiv's blog on SmartGWT Pro/EE, which is the link I meant to post before:

Sweet!!! I noticed that you have Oracle support. Do you have a way to support the Oracle XMLType, at least a way that is more direct than the way that I have done this before, where I kludged Hibernate to be able to store XML in the database? On Tue, Aug 4, 2009 at 4:38 PM, ckendrick

We do give you the ability get in and override any part of the generated SQL as a Velocity template. Simple example: http://www.smartclient.com/smartgwtee/showcase/#large_valuemap_sql Tour de force (dynamic reporting with filter, sort and data paging, no server code required):

I'm with Chad here... Dynamic Data structures sound cool and even a little sexy, but they are by definition contradictory. Your data structure is like the foundation of your application: you want it to be as solid as possible. Allowing for extensibility for future improvements is one thing. A

Hi Kaspar, I found some javascript +XML libraries out there. My issue was that none of them really modeled the questionnaire I was asked to build. I rolled my own using GWT+XML. It isn't that difficult. Once I had the DTD, the survey designer could use that DTD in an XML aware editor to create

Kaspar, While you probably can find the kind of tool you are looking for (I don't know of any since I don't have a need for them), I would question your data design. You should be able to design your data so that users can add questions without changing the data structure, just the data content.
