Sure, I can provide those steps.
Before start, I have uninstall all the jres and java sdks(64bit/32bit) to
have clean installation.
1 ) go to this link:
http://www.oracle.com/technetwork/java/ ... index.html
and there is 4 big icons like, Java, JavaFx, Netbeans, JavaEE
under the Java, click "JDK".
On the Platform, select windows.
!!!make sure you don't click windows x64 or anything else!!!
and click continue. (you don't have to sign up for Oracle to download)
2 ) On the next page, by clicking
"jdk-6uXX-windows-i586.exe", the download will be started.
3 ) Once download is finshed, install the Java SDK with default setting*.
4 ) After the installation, make sure go to your Environment Variables
and check the setting.
If it's not done by installer, set the JAVA_HOME,
and set the path to your java jdk bin.
(I believe most java users know this by now.)
5 ) make sure java and javac command works in cmd.
6 ) Install the mindstorm CD software came with NXT, and that will install
the driver for your NXT.(I ran the mindstorm software to make sure it's
installed correctly...) Some people say to download the most updated
driver from the lego website, but mine seems the CD software(driver
included) that came with NXT did just fine. However, if you don't have the
CD please, go to the link below to get the most updated driver.
http://mindstorms.lego.com/en-us/suppor ... spx#Driver
7 ) Now install the lejos. I downloaded Lejos_nxj_0.8.5-Setup.exe from the link....
and installed it with default setting*.
During the NXT lejos firmware installing,
even though you tried reset/taking out battery,
if you keep hearing ticking noise, please use the
CD software(Mindstorm, If I'm right) to go back to factory setting,
and try to reinstall the lejos and refresh the NXT head with lejos.
I had to try two times, and in the second trial,
I have mine refreshed as expected.
ALSO, if your computer doesn't see the NXT using mindstorm software
on the same computer that have lejos, find other computer that
don't have lejos to refresh and put it back to factory setting.
(To upload the mindstrom firmware
in the mindstorm program...do the following steps..
tools>update NXT firmware>Download)
8 ) test nxjc nxj command and if you don't see error good to go!
*default setting installation : by clicking Next> multiple times
during installation without changing anything.
Thank you for suggestions Andy.
