 FAQ-O-Matic : Linux- and Solaris-specific : Installation :
I've installed JBuilder on Linux and my keyboard dosn't work at all! |
| Check your keyboard's NumLock key. If this key is 'on', your keyboard won't work as it usually does. This is true of all X11 applications, not just JBuilder and Java.
I don't know if XFree86 goes deaf to keypresses when NumLock is on, or if it's adding some sort of key modifier bit to the keycode which applications aren't expecting to see. | |
| If you're seeing this behavior on Red Hat 7.1, or if JBuilder seems to
work but dumps core when you click OK, the problem is likely to be the IBM JVM
bundled with JB4. It seems to be incompatible with the glibc
libraries provided with Red Hat 7.1.
Your best bet is to download a newer JVM. Sun JDK 1.3.1 is known to work okay. I haven't heard from any one who replaced it with the most recent IBM 1.3.0 release but it's worth a try if you really want to stick with the IBM JVM.
To replace the bundled JDK, download Sun's 1.3.1 and install it somewhere
on your machine. Then edit jbuilder4/bin/jdk.config and edit every
statement which references something in the original jdk, and replace
them with corresponding references to the new jdk.

| In JBuilder 5 on Mandrake 8.1, leaving the numlock key enabled has caused all of the tool bar buttons to be non-functional. IE, it seems to accept mouse focus (the button repaints to look raised) but clicking on the button does nothing.
Also, none of the F1-F12 function keys work. But oddly enough, the menu works, as do right-click context menus. Pressing the numlock key to clear it solved the problem.
Bizarre!
