About UltraLightClient 6.2
Release 6.2 includes the following new features:
| Feature | Description |
| Test Framework | The test framework is a tool to enable functional testing of
UltraLightClient applications. It shields the test developer from all
UltraLightClient specifics.
|
| QuickTest Professional Integration | Use the popular record & replay tool to define your functional tests. The QuickTest Professional integration saves you from writing complex synchronization code and therefore enables fast and reliable functional tests for your UltraLightClient applications. |
| Support Fixes | This release contains a lot of fixes and features that were reported to the support mailing list. |
| Cell Based Pop Up Menus | Some components are built out of smaller sub-elements. These
sub-elements are usually referred to as cells. UltraLightClient
supports the following cell-based widgets: ULCList, ULCTable,
ULCTree, and ULCTableTree. For these widgets it is
now possible to define a component pop-up menu that shows different
menu items for each cell.
|
| Custom Blocking Feedback | UltraLightClient blocks the user interface during a
synchronous server round-trip. By default, UltraLightClient indicates
a blocking user interface by means of a special mouse cursor. It is
now possible to define a custom blocking feedback.
|
| Multi File Selection | UltraLightClient's file chooser dialog is now able to select more than one file at once. |
| Swing API | This release contains almost 100 new properties and methods for existing components plus one completely new component. You can find detailed information for the most important features in the next sections. |
| ULCSpinner | ULCSpinner is a new control that enables an easy
selection for numbers, dates and list elements.
|
| ComponentOrientation | All components now support left-to-right and the
right-to-left component orientation.
|
| Full Mnemonic Support | It is now possible to set mnemonics, as well as the exact
mnemonic index on labels, buttons, and tabs.
|
| L&F Window Decoration | Dialogs and frames now support look & feel window decoration.
Therefore dialogs and frames can now inherit the window decoration
from the installed look & feel and not from the underlying host
operating system, e.g. Windows.
|
| Slider Labels | The labels in ULCSlider can now be defined in detail
to show their various values.
|
| Progress Bar String | ULCProgressBar can now contain an information
string, e.g. to display the percentage completed or the time required
for an operation.
|
| Tab Layout Policy | A ULCTabbedPane with a lot of tabs can now display
scroll buttons for faster tab navigation.
|
The sections Fixed Bugs and Implemented Feature Requests give an overview of the most important differences between UltraLightClient 6.1.3 and UltraLightClient 6.2.
To migrate from UltraLightClient 6.1.3 to UltraLightClient 6.2, please see the migration notes.
Version Notes
UltraLightClient 6.2 requires the Java Runtime Environment (JRE) 1.4.2 or later on the server and on the client.
To deploy an UltraLightClient application in a J2EE server the server needs to support either at least the Servlet 2.4 specification or at least the EJB 2.1 specification.
Modules, Parts and Release Structure
The UltraLightClient release includes all components required to successfully develop and deploy UltraLightClient applications. The UltraLightClient modules, parts, packages, and the structure of the current release are described in the following sections.
Modules
The UltraLightClient release is split into modules. Each module belongs to exactly one of five categories:
- Base
The UltraLightClient core.
Always needed, for development and deployment. - Container
Server-side integrations into containers, e.g. Servlet, EJB.
Only needed for server deployment. - Environment
Client-side integrations into environments, e.g. Applet, JNLP.
Only needed for client deployment. - Addon
Utilities and extensions, e.g. test framework, QTP integration.
Only needed on demand. - Sample
Samples demonstrating the usage of UltraLightClient, e.g. Hello, ULCSet, OnlineShop.
Not needed during development or deployment.
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:
- lib
Jar files that contain the module classes.
For sample and add-on modules the required libraries. - resource
Only for sample modules: the required resources, e.g. images, property files - src
Either complete source code or source stubs.
The source stubs are used to enable code completions in IDEs. - webapp
Only for sample modules: ready to deploy web application, i.e. war files
Parts
Each of these modules can contain up to four parts:
- Client
Contains classes to be deployed on the client side.
Runs inside the sandbox. - Trusted
Contains classes to be deployed on the client side.
Does not run inside the sandbox. The additional permissions required depend on the module. - Server
Contains classes to be deployed on the server side. - Development
Contains all classes needed during development, i.e. the client, trusted, and server parts plus some additional development classes.
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.

Migration Notes
Enhancements for Client File Access
The enhancements for client file access made it necessary to change the API:
- In addition to the file path the file name is available as well. The file name is now provided as an additional parameter to the IFileChooseHandler.onSuccess(), IFileStoreHandler.onSuccess(), and IFileLoadHandler.onSuccess() methods. This is just an additional parameter that therefore can be ignored in existing code.
- The file chooser now supports multi file selection. The IFileChooseHandler.onSuccess(), and IFileLoadHandler.onSuccess() methods now provide the result as an array parameter instead of regular ones. For single file selection the corresponding information can be found in the first element of the array parameter.
Removal of deprecated ULCComponent.setPopupMenu() methods
The methods ULCComponent.setPopupMenu() / ULCComponent.getPopupMenu() have been removed. Use ULCComponent.setComponentPopupMenu() / ULCComponent.getComponentPopupMenu() instead.
