Mac OS Platforms

Starting with OpenJNLP 0.7, the OpenJNLP cache is in the ~/Library/Caches/OpenJNLP folder. OpenJNLP will automatically migrate older caches to the new location on startup if necessary.

Mac OS X users can 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.

Unix Platforms

OpenJNLP checks for JAVA_HOME to find the Java executable, falling back to /usr/bin/java if JAVA_HOME is not set. Most unix distributions seem to use /usr/bin/java which is what the OpenJNLP shell script assumes.

Windows Platforms

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.

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.
