问题 Before installing Eclipse, I had OpenJDK as the default JVM. Recently I changed it to Sun Java. I did this because Eclipse Helios was running really slow. Unfortunately, it is still slow...

问题 I'm new to PHP and the whole LAMP stack but I've managed to get it up and running on my Ubuntu 10.10 system. Everything seems to be working with the exception of error reposting in the browser which I just can't seem to get working (and which I can't work without!). I've read a number of article and other threads which indicate that the following values should be applied in the file /etc/php5/apache2/php.ini : display_errors = On display_startup_errors = On I've restarted apache2 and even
