New release of Java 1.5

Sun released Java 1.5.0_17 today. This release fixes (among other things) the regression bug of Java 1.5.0_16 which made it impossible to view and edit metadata in Conzilla. I wrote about this in a previous blog post.

Generally I recommend to use Java 1.6, but if you have to use 1.5 for some reason you can get the new version directly from Sun.

Recent problems with launching Conzilla

I got several emails these days from people who were not able to launch Conzilla anymore. The reason was an exception (“java.net.MalformedURLException: no !/ in spec”) during start up.

I investigated the problem (which is caused by a regression bug of Sun’s most recent Java 5.0, i.e. 1.5.0_16) and tried to work around it, but came to the conclusion – as many other developers who tried to solve the very same problem – that it is best to wait for a fix from Sun.

The reason is that it would require too many changes in the code and even some major refactoring. Apart from that, even third-party libraries as e.g. log4j are affected. Conzilla is not the only application which has been broken, basically all applications making use of Java Web Start are affected.

Bugs have been reported to Sun:

http://bugs.sun.com/view_bug.do?bug_id=6746185
http://bugs.sun.com/view_bug.do?bug_id=6753651

Let’s hope that Sun fixes this bug very soon, until then my recommendation is: Do not use JRE/JDK 1.5.0_16, and if you happen to use it, downgrade to an earlier release, or upgrade to 6.0/1.6.

I will keep you informed regarding this issue.

Conzilla 2.2.5 released

Two bug fixes:

  • Corrected SHAME ULM formlets. because of a typo some URIs were invalid upon automatic generation.
  • Fixed an error related to serialization to RDF/XML. in some rare cases just N-TRIPLE worked. Saving to RDF/XML and RDF/XML-ABBREV works again.

Conzilla should update itself through Java Web Start when you start it next time.

Conzilla 2.2.4 released

Two bug fixes:

  • Non-ASCII URIs could not be properly published to Collaborilla (this bug made this quick bug fix release necessary)
  • The reload button did not take the threaded/unthreaded setting into consideration

As usual, Conzilla should update itself through Java Web Start. Have fun.

Conzilla 2.2.3 released

This is a maintenance release, fixing the following bugs:

  • “Contexts” context menu was disabled when clicking for the first time
  • Shortcut and menu for closing a tab/context-map did not work
  • “Window”-view could not be closed via X-button in the window frame
  • “Save” button was always enabled
  • HTTP implementation of RemoteStorage did not timeout properly
  • Multithreaded loading of maps caused problems; it is optional now and deactivated it by default
  • Sindice client did not time out
  • Metadata popup sometimes showed up beneath map elements
  • Added menu to manually clear the container and metadata caches
  • Content URLs did not open in a browser on newer MacOS systems

Conzilla 2.2 requires a Java Runtime Environment in version 1.5 or newer and can be installed via the download page. If you already have an installation of Conzilla 2.1 it should be sufficient to launch Conzilla via the shortcuts. Java Web Start will then take care of the upgrade.

If you have comments or suggestions you can send them directly to the Conzilla mailing lists.

Conzilla and Collaborilla go REST

I just released Conzilla 2.2.2 together with Collaborilla 1.1. The biggest improvement of these versions is the switch to RESTful web services, which makes it finally possible to access Collaborilla even in very restrictive networks – the new services use standard HTTP port 80 which shouldn’t be a problem anymore. To make the picture complete, I also added support for HTTP proxies, so there is no excuse anymore for not being able to use Conzilla.

The noteworthy changes since version 2.2.1:

  • Support for Collaborilla 1.1 and the new RESTful web services
  • Support for connections through HTTP proxies
  • Possibility to conditionally empty the disk caches
  • Fix for problem on MacOS which prevented to open URLs in web browsers
  • Fixed some NullPointerExceptions

Go and get it. Or if you already have an older version: just launch it via Java Web Start, the upgrade should then take place automatically.
