I was getting a lot of hassle from eclipse after updating to ubuntu feisty. Finally I found the problem. I was running GNU java VM (GIJ) as default, while eclipse is build to run with the SUN java VM. The GIJ is only Java 1.4 and it therefor not working correctly.

Run the command `java -version`. And if you get the following, it’s no good:
java version “1.4.2″
gij (GNU libgcj) version 4.1.2 (Ubuntu 4.1.2-0ubuntu5)

Just install the SUN java packages (using apt) and then run `update-java-alternatives -s java-1.5.0-sun`. When you run `java -version` now, you should read:
java version “1.5.0_11″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Server VM (build 1.5.0_11-b03, mixed mode)

Now re-install eclipse and it will run like a charm.

Eclipse seems to break more often than ‘Mr glass’ in Unbreakable. But simply reinstalling isn’t a strait forward task either. When uninstalling, the tool bar breaks (k, thats fixed with a restart), but more importantly eclipse won’t start again. You get a message stating that an error is logged in ~/.eclipse/configuration/1177584905255.log (filename changes).

Running multiple instances of Apache

Life as a shared hosting provider hasn’t become easier after PHP decided that they would allow compatibility breakage between mayor versions. Some providers managed to keep there customers satisfied while only supporting PHP 4, but lots of new projects are PHP 5 only and the problem will become even bigger when PHP 6 is released.

Usually a daemon (a service for you windows folks) is started once, with only one instance running. The same goes for Apache. However when we look closely at the apache config, we see that variables which prevent apache from being started twice, the pid file, lockfile and ip/port, can be configured. When starting apache, the config file can be specified, which allows to run multiple instances of apache (on different ip’s). Continue reading »
