Re: NullPointerException at findToolsJarFile

[Dain Sundstrom]

You shouldn't... but there is a bug in my code.  I checked in a fix,  
but I'm still testing it.  It should be in the next daily build (when  
David Blevins gets the scripts upgraded to support subversion).

The wiki says:
If you use Java Server Pages then Geronimo will need to have the Java
Development Kit tools.jar file on its classpath. If you're using a Sun  
JDK
then the easiest (although cheesiest) way to make this possible is to  
copy
tools.jar from $JAVA_HOME/lib to $JAVA_HOME/jre/lib/ext.

(http://wiki.apache.org/geronimo/Running)
although I found that you need to do this just to get the server  
started.

This is a bug.  It should simply print the warning and move on.  Not
having a tools.jar is not fatal, but you will not be able to compile
jsp pages.
I'll file a bug report on this.

This problem may happen if you try to run the server via the
standalone JRE (C:\Program Files\Java\j2re1.4.2_05\bin\java.exe).  
You
need to run it either via the JDK (say,
C:\j2sdk1.4.2_05\bin\java.exe) or the JRE shipped with the JDK (say,
C:\j2sdk1.4.2_05\jre\bin\java.exe)
Almost there :) The problem is that the default jvm on Windows is
picked up from %WINDIR%/system32/bin. So, unless another jvm is in  
the
path first, that's used and brakes the run. However, you suggested  
the
fix and it works now. It's required to either specify the default jvm
in PATH or use the fully qualified path of preferred jvm.

I'd say majority of Windows users are at risk, and we need to fix it
soon.
Also, note that although the server started fine, the message from
ToolsJarHack says that the class still can't find tools.jar.
Thanks Gianny!
