Feature	Description
Support Fixes	This release contains a lot of fixes and features that were reported to the premium support mailing list.

The sections Fixed Bugs and Implemented Feature Requests give an overview of the most important differences between UltraLightClient 6.2.1 and UltraLightClient 6.2.2

This build is based on ULC 6.2.1 Please see the ULC 6.2.1 release notes for additional information.

 

Version Notes

UltraLightClient 6.2.2 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.

UBA-7106	Drag from an ULCTableTree triggers a lot of sun.dc.pr.PRExceptions when the tree column is other than 0
UBA-7168	button 'enabled' state not properly reflected on server-side when enabler attached
UBA-7191	Memory leak with renderers in ULCTable	Setting a new model now clears associated TemplateCaches.

UBA-7278	ULC sets JCheckBox.requestFocusEnabled to false in Java 6
UBA-7280	Deleting a tab before the selected tab is broken in Java 6	The pre Java 6 behavior is now enforced by ULC => ULC keeps the selected index and not the selected component.
UBA-7282	ULCFiller.getPreferredSize() / getMinimumSize() / getMaximumSize() does not behave as in Java 6
UBA-7332	Session may still be blocked in IBlockedSessionListener.sessionUnblocked
UBA-7338	ULCSpinner client proxy updates value on server but does not fire valueChanged event when the value has changed but not committed

Implemented Feature Requests

PR	Description	Comments
UBA-916	Drag & Drop with external applications should support other data flavors than string flavor	New API: DefaultTransferable AbstractDragGestureListener.createTransferable() DefaultTransferable.addTransferData() / removeTransferData()
UBA-1075	Improve Error Message when no ULC Application Host available	Improved error message for the following cases: Unable to authorize Unable to create connection (unknown host) Unable to send request (unexpected HTTP response code)

Migration Notes

Renamed UltraLightClient specific Jemmy operators

The old namings were misleading therefore we changed them:

• LazyJTableOperator => ExtendedJTableOperator
• LazyJTreeOperator => ExtendedJTreeOperator
• LazyJListOperator => ExtendedJListOperator
