Rapid Development for WebSphere Portal

Total properties in collections

OpenXava is a framework for Rapid Development of portlet applications compatible with WebSphere Portal. It is well-suited for business and database oriented applications.
OpenXava allows you develop applications just by writing simple domain classes with Java or Groovy. The user interface is generated automatically in runtime, without code generation.

OpenXava 4.3 adds support for total properties in collections, it has a new editor for HTML_TEXT stereotype, add info and warning messages and some other useful new features.

Total properties in collections

@Stereotype("HTML_TEXT")
private String recipe;

addError("this_is_an_error");
addWarning("this_is_a_warning");
addMessage("this_is_a_message");
addInfo("this_is_an_info");

You get:
