Checkboxes and Composite Keys – Friends or Foes

What do you think is the best technique in setting up the value of a checkbox if it corresponds to a database record that has a Composite Key? Should one concatenate the values representing the composite key, then, parse those values again at the server side when the form is submitted? Is there a more elegant teqhnique? Any custom...

Hibernate – passing a complete object to HQL or find()

I’m currently experimenting with Hibernate (hope I’d get back to OFBiz soon; or that OFBiz uses Hibernate sooner). Is there a way that I can retrieve (find/load) records from the database using my an object in the following manner: {% highlight java %} …myObject.setFoo(f);myObject.setBar(b);//foo and bar does not relate to the Object’s primary keys//Other properties have null or unset...

Back To Basics

It seems that I’ll be entering the debate once again. To Struts or not to Struts? I’m with. But I’m tired. I’ll try to base my next discussion on this.

Ofbiz with MaxDB

Finally! I was able to get Ofbiz running with MaxDB. First impression about MaxDB by MySQL (formerly SAP DB) that it’s quite nice. Problems are easier to locate and solve than MySQL (so far). The Database Manager GUI rocks (though I wonder if Database Administrator from MySQL can connect to MaxDB – but perhaps another day for that issue)....

Being an ofbiz admin is not easy I still have a long way to go with the design, database and architecture. A first problem is how can I upload the set of data...

ILOG – JViews Gantt

Seems like JViews Gantt is a good candidate for one of the projects that we?re currently developing. We?re interested in having an output similar to that of Microsoft Project in a thin-client environment (JViews Gantt capabilities sounds good). It still too early to decide weather it?s the right solution (JSP tags, features, ease, scalability, etc…). Does anyone have an...

OFBiz

I planned to start learning OFBiz seriously (after spending few intermittent weeks reading about its structure, architecture and capabilities). I took the decision yesterday after a discussion with an IT operations manager in one of the companies that is actually using Ofbiz to make money. I’m starting to believe that putting together these broad range of solutions with such...
