• Had trouble getting Oracle SQL Developer (version 1.5.5) to run. First it told me I needed to install the Java SDK. So I did. Then it told me it couldn’t find the Java Virtual Machine. I tried a few tricks suggested on various message boards involving modifying sqldeveloper.conf and changing the SetJavaHome variable, but no luck. Finally, I got some advice that sql developer doesn’t support 64-bit Java. So I installed the 32-bit version (jdk-1_5_0_22-windows-i586-p.exe) and that did the trick
• I had a little trouble with sendto, believe it or not. My C:\Users\myid\SendTo was locked. Finally found a tip that I needed to get to my roaming profile via %APPDATA%\Microsoft\Windows\SendTo

So I’m able to work for now. But after my temporary admin privileges expire, God knows what will happen.

Apparently there’s an issue running aptitude or synaptic (using Xubuntu Gutsy) on a secured wireless network. It just doesn’t seem to work. I’m sure there’s a fix for it and if I had hours of spare time, I’d find it.

Meanwhile, I took my laptop to a wireless network with a unsecure guest connection and was able to run

sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

(Thanks to ubuntugeek for that one) Then I did the same thing for sun-java6-jdk.

Then I used mousepad to write up a standard helloworld.java example. I went to my terminal and did

sudo javac helloworld.java -d /home

Without the -d I had no idea where the class file was going. Without the sudo I got permission errors.

then I ran

java helloworld

and it worked!
