Notes on Usage

New Features

• Will now use Main-class attribute of main jar manifest if no main-class specified in <application-desc> tag of JNLP file.

Bug Fixes

• Properties were being parsed but not passed on to launched app; now handled correctly.
• Fixed problem with URLs containing certain characters like '&'.
• On Mac OS X the main window was opening twice in certain situations. This problem has been resolved.

Notes on Usage

New Features

• JNLP Applets now supported.
• OpenJNLP can be run via Java Web Start (JNLP distribution).

Changes

• OpenJNLP library (parser, launcher, cache) re-engineered to truly be embeddable in apps other than OpenJNLP. Now available to developers as a separate distribution.
• Changed external launcher to be inside OpenJNLP cache, allowing for better cross- platform behavior and self-updating of the external launcher.
• Simplified packaging of classes into fewer jars, making components more manageable.
• Now using latest version of SAX (SAX2 r2).
• Now using NanoXML 2.2.
• Improved javadoc.

Bug Fixes

• Fixed downloading of resources every time an app is launched, now properly uses the cached version if up-to-date.
• Fixed problem where resources were downloaded more than once in some cases involving nativelib resources.
• Fixed ability to get/launch JNLP descriptors that have no href defined in the <jnlp> tag.
• Many small error checking changes to improve handling of unexpected situations.
• Changed openjnlp.sh script on unix to check for JAVA_HOME to find java binary.
• Fixed double-line problem with messages in OpenJNLP console window.
• Paste now works on Mac OS X in dialog for entering JNLP URL.

Notes on Usage

New Features

• Improved info window.
• Console window for viewing output of launched apps.
• Native library support in app launching.
• Locale and platform (OS and architecture) support.

Changes

• Cache API has been revamped. This lays the groundwork for version-based resources.
• Lots of javadoc comments added in OpenJNLP library.

Bug Fixes

• Minor performance increase when starting up.

Bug Fixes

• When getting a new JNLP app, the app list is now updated immediately.
• Properties are now parsed from the JNLP file and set when a JNLP app is launched.
• JNLP parsing no longer fails when encountering unknown tag.
• Version info now shows in Mac OS X Finder.
• Internal changes to parsing and caching that better support the notion of multiple caches.

Notes on Usage

• In order to provide a better experience for all Java users, the development of the Java2 is now separate from the JDK 1.1 version. This branching means that releases for each Java platform are not tied to other platforms and functionality can be tailored for the best-possible implementation.
• Mac OS X users can now assign OpenJNLP to be the handler for JNLP documents which allows double-clicking of documents and web-link launching possible. Due to known problems with Mac OS X and Java, document-opening may only work properly if OpenJNLP is already running.
• The Windows implementation requires that Java is properly installed and part of the PATH when running programs. Basically if you can invoke Java directly from the Run command, OpenJNLP should work fine.
• OpenJNLP on Unix uses a shell script to find the java executable, and it may need to be tweaked depending on the system it is running on. Most unix distributions seem to use /usr/bin/java, which is what the OpenJNLP shell script assumes.
• All platforms: cache converts itself to new structure if it detects an old-style cache. When converted all resources are considered out of date and will be downloaded when necessary. If an app fails to launch it may be necessary to delete it from the cache.

New Features

• Feedback! Users are now presented with activity feedback during an app launch.
• A launch can be canceled while in progress.
• Resources (such as jars) are updated when out of date. This is implemented via JNLP "basic" updating using Last-Modified timestamps.

Changes

• Cache layout simplified. Cache will automatically convert old-style caches.
• Resources now manage themselves within the cache using the new CachedResource class.
• Packaging is simplified. There are now two jars: openjnlp-app.jar and openjnlp-lib.jar. SAX2 and NanoXML are still required.
• ClassLoader is now based on the Java2 java.net.ClassLoader.
• OpenJNLP "cache:" URL has been removed, no longer used.
• Descriptors (JNLP files) are now cached according to the JNLP specification. This means if the jnlp tag has an href it is added to the cache, otherwise it is not.
• JNLP Descriptors that aren't cached can not be launched via OpenJNLP without entering the URL although the resources are cached.
• OpenJNLP now has a registered creator code for Mac OS platforms, allowing JNLP documents to be associated with the application.

Bug Fixes

• Big changes have altered the bug landscape, all aspects of launching and caching have been significantly modified.
• Process streams (stdout and stderr of externally-launched apps) are now being captured and sent to the console (System.out and System.err).

Notes on Usage

• On Mac OS X, Java apps don't seem to properly get open document notification, so an ugly hack has been implemented to get around this problem. Also, the Dock seems to get confused at times by the multiple appearance of OpenJNLP in the Dock.
• For Mac OS Classic, some undocumented behavior of MRJ is being used to get separate JVM launching working. Essentially all of the activity takes place in a hidden folder on the System disk, but it is unclear if that folder's name remains constant across localized versions of Mac OS.
• The Windows implementation requires that Java is properly installed and part of the PATH when running programs. Basically if you can invoke Java directly from the Run command, OpenJNLP should work fine.
• OpenJNLP on Unix uses a shell script to find the java executable, and it may need to be tweaked depending on the system it is running on. Most unix distributions seem to use /usr/bin/java, which is what the OpenJNLP shell script assumes.

New Features

• Apps are launched in external virtual machines.

Notes on Usage

• Previous OpenJNLP users should remove their existing cache directory, since this version of OpenJNLP implements a somewhat-improved caching structure. Anything cached by previous versions of OpenJNLP will be invisible to the new cache architecture and will needlessly waste disk space.

New Features

• All-new user interface! Shows list of previously-parsed JNLP apps and allows running by selecting from the list.
• SAX2-compatible XML parsing.
• Source code distribution and javadoc are now available.

Changes

• Cache restructured to provide better layout of resources.
• Improved ClassLoader. It is a simpler implementation and has some performance improvements.
• The OpenJNLP "cache:" URL format has changed.
• SAX2 XML parsing has been implemented. Still using NanoXML as the XML parser.
• The OpenJNLP distribution has been split into multiple jars. The JNLP processing and caching classes are in openjnlp.jar while the OpenJNLP application is comprised of openjnlp-app.jar and desktop.jar.

Bug Fixes

• Jar files in the cache are no longer held open by the cache: URLStreamHandler or the ClassLoader.
• JNLP resource MIME-typing is handled by JNLPParser instead of the GUI.
• Success/failure checking of HTTP access to JNLP files added.

Changes

• The wretchedly slow ClassLoader has been replaced with a spiffy new ClassLoader that is way faster.
• Gracefully detects missing Swing.

Bug Fixes

• Fixed memory leak in DefaultCache.establishEntry().
• Fixed cache URL handler, all resources should now be loaded properly from jars.
• getResourceAsStream() now works properly.
• Clarified security warning message.

New Features

• Now launches parsed JNLP apps in same JVM.
• Caches JNLP apps and resources locally.

Changes

• JNLP file and icon are now looked for in cache before network.
• Detail window now lets users launch app.
• Now performs permissive parsing, will attempt to parse any URL ending with .jnlp extension.

Bug Fixes

• Fixed background color of debug info on Windows.

New Features

• Can now view JNLP source of retrieved file.

Changes

• Extensive enhancement of Detail window.

New Features

• Initial release.
• Can enter URL and view JNLP information.
• Can select local JNLP file using file chooser.
