About Canoo RIA Suite ULC - Update 5

Canoo RIA Suite ULC includes the following new features:

Feature Description
ULCWorker: Widget to facilitate long running asynchronous tasks To spawn threads to handle long running and non-(GUI-)blocking (hence asynchronous) tasks is a delicate task to server-side programmers but still it has to be done from time to time.

So far the only support was ULCPollingTimer, which allows to poll for the asynchronous task's completeness.

With ULCWorker an API shall be provided that can take the same place in ULC programming as SwingWorker in Swing programming.

Support for property change events Using a custom event in ULC extensions is somewhat cumbersome. It is easier to use an already existing event like ActionEvent.

However none of the supported events offers the possibility to pass a single property value. This means that as soon as you have an event that contains a value you are forced to implement a custom event.

PropertyChangeEvents are events that hold a single value. See com.ulcjava.base.shared.event for more details.

Client proxies sent to server When we transport a server proxy (aka ULCProxy) from server to client, the serialization engine converts it into an Oid. But the same did not happen when a client proxy (aka UIProxy) were transported from client to server (see UBA-7066). This is now possible.

This change has been triggered by a critical bug in ULCLoad (see UBA-8508) and forces us to make some changes in the API. See migration notes for more details.

Please see the Canoo RIA Suite Update 4 release notes for previous release notes.

The sections Fixed Bugs and Implemented Feature Requests give an overview of the most important differences between Canoo RIA Suite ULC Update 4 and Canoo RIA Suite ULC Update 5.

To migrate from Canoo RIA Suite Update 4 to Canoo RIA Suite ULC Update 5, please see the migration notes.

 

Version Notes

Canoo RIA Suite ULC Update 5 requires the Java Runtime Environment (JRE) 1.5 or later on the server and on the client.

The deployment of a Canoo RIA Suite ULC application requires a JEE server that supports at least the Servlet 2.4 specification.

 

Packages, Modules, Parts and Release Structure

UltraLightClient is part of the Canoo RIA Suite. It consist of the ULC Core that includes all components required to successfully develop and deploy UltraLightClient applications. Additionally there are several extension packages that provide extended functionalities. The UltraLightClient modules, parts, packages, and the structure of the current release are described in the following sections.

 

Package ULC Core

ULC Core contains everything that was in previous version of ULC enhanced with the new features: extended visual Effects, Charts, Animations and export to Google App engine.

Modules

The UltraLightClient release is split into modules. Each module belongs to exactly one of five categories:

The category and module names are reflected in the directory structure of the release, e.g. environment/applet for the applet module that belongs to the environement category.

A module directory contains subdirectories with the following contents:

 

Parts

Each of these modules can contain up to four parts:

The part names are reflected in the filename of the jar files in the lib and src directory of the corresponding module, e.g. ulc-applet-client.jar and ulc-applet-client-src.jar for the classes and source stubs of the applet module that have to be deployed on the client side.

 

Package ULC Table Plus 1.0.4 (JIDE Grids v3.1.1)

ULC Table Plus integrates the JIDE grids library that provides a table with various extended features.

 

Package ULC Web Integration 1.0.3 (JxBrowser v2.9.1)

ULC Web-Integration integrates the JxBrowser library. With this package you can integrate any web page directly into your ULC Application.

 

Package ULC Enterprise Portal Integration 1.0.2

With this package you can integrate an ULC Application into your enterprise web applications or your enterprise portal server.

 

Package ULC Office Integration 1.0.1

This package bundles Apache POI and iText to produce PDF and MS Office documents integrated into your ULC Application.
