The answer to your question is YES...

Spring can do your use case very easily. Please visit my blog if interested at: http://pragmatikroo.blogspot.com/.

I believe this article I wrote recently, might be relevant to your question...

In the article I used Spring Roo for its implementation, however I refer to another implementaion using regular Spring too.

Here is the link: http://viralpatel.net/blogs/2011/02/spring-roo-save-read-blob-object-spring-roo-tutorial.html.

I hope it helps you

I have worked with both rads...
Personally, I think that at this point Spring Roo has much more to offer to the developer.


1) Project definition based on an effective and elegant shell -ide and standalone.
2) It uses Modular Jave via an OSGI container so it is straight forward to extend if required.
3) It scaffolds ready-to-run web apps easy to customize to your requirements all the way to production.
4) Powerful database reverse engineering for directly creating entities.
5) At the end it is pure Java so you don't need to learn anything to start using it.

And much more...

Here there are some links if you decide to learn more on SR: http://viralpatel.net/blogs/author/jose-delgado,

Hello James,

I am using Hibernate...
Some context: I am creating java-based web app using RAD new paradigms. I created an app named Grids-and-Charts (gnc).
GNC using a bunch of global indexes like: GNP, Education expenditure, Inflation, etc to create grids and charts with the data.
You can visit the app at gnc. The index data as originally defined is as a country/year pair.
The data have different years ranges. Creating the index grid and chart per country was straightforward. Next I wanted to provide some analytical
capabilities to gnc that requires operate the indexes of the countries all together. In other to do that I had to pivot the data to a have a country/y1/y2/y3/... view.

The sql for creating the pivot view was straightforward too. At that point JPA just would -only- need to know/register about the new entities -on the fly- to start operating on them.
That brought me to the search on JPA entities on the fly thing. I accomplished my goal using mostly oop. I wanted to know if there is a more automatic way for doing it.

Thank you

Hi friends,

I faced the following situation with JPA on a recent project:
I need to create new entities on the fly based on already existent entities.

As expected the new entities are not registered on initialization, there are no classes or tables on the db that represent them.
The new entities should be fully operational i.e navigation-able, search-able, etc. on the same User session that create them.

I wonder how can I handle this use case with JPA?

Thank you in advance

Hi there,

It is not bad at all...
When I started on this project; I was -as well- regretting having to use it.

After a short period of adjustment I started to like it.

Is this only wrinkle that I need somehow to iron it

I wonder why jasper is yanking the comments from the page??

Any idea?

Thanks again

Hi,

I am currently working in a project that uses jsp documents on tomcat 6.026. In other words jspx type of jsp.

I would like the to use "conditional comments" as stated by MS to handle its browsers . The referred cc uses
<!-- --> coding to enable the conditionals in a page. However this the the same syntax for enabling
comments in an xml document. For some reason jasper compiler is not preserving the comments when the document is
translated into a servlet. Consequently the cc are not making in to the final page.

I wonder if there is way to deal with the situation that I just previously described

Thanks in advance
