Sun, JDK, PATH:A few years later...

I worked in Java as it came out and, back then, you needed to change the PATH variable manually (at least when programming on Windows). Now I made a loooong break and have only read about what's happening in the Java world (to stay in touch with that world) while I worked in VB/VC++. Now I installed JDK 1.4.2_01 (the latest!) to try it and maybe use it in the future (for a project).

Guess what? You still need to manually change the Windows PATH variable and add the path where your latest JDK is to it! I mean... that can't be that hard (JDK is installed using InstallShield - ie. full access to the OS) or am I missing something?

Gotta love changing that PATH variable. Of course, its easier in Win 2K/Xp now that you can access environment variables from the control panel - back in Win 98 I believe this had to be done in autoexec.bat if you wanted the variable to be set everytime. Not to mention the CLASSPATH variable too...

For what it's worth, you have to adjust your path in *nix to get to all the fun stuff. Equal opportunity challenging install.

Messing with the PATH... what more do you expect from Sun.  :)

What's annoying is that it seems that the version of the JRE in the registry takes precedence over JAVA_HOME environment variable.    Has anyone else had this problem?

I have 1.4.2 and somehow java.exe ended up in the windows\system32 directory after install...

TBH it frustrates me more when installations do these things for me.

I always thought it would be nice for NT/2000/XP to support symbolic links in the filesystem so the PATH doesn't need to be changed like this, just do a: 'ln -s c:/java/j2sdk-1.4.2/bin/java c:/windows/system32' or something...

NTFS does support 'junction points' which look like sym links.

You can create them using the junction utility from http://sysinternals.net/ntw2k/source/misc.shtml

Actually you don't need the junction point bit, I've done it here by adding a partion then joining into the normal tree.
Useful to know about if you want to expand say a database directory without too much messing around, create a new partition, stop the service, copy \program files\SQL to the new drive , rename the old SQL directory, then add the mapping (It's under Control panel / Computer management / Storage / Disk manager / Change drive letter and paths on Win2K), restart the service.
Works well as an easy way to add more space without having to reinstall or change drive letters.
