Hi Bharath,

which JDK and Windows OS version do you use? I do not
understand why some versions of windows require the
SystemDir environment variable. There's no reliable
way to read or set environment variables from java.=20

I have just tested on several systems, including XP
home and win98, none of these need SystemDir.  The
only system that I know of is XP, but this problem
goes away when I install network programs. =20

Maybe it is necessary to set a registry entry which
points to the correct SystemDir.  I will check this.

In JDK1.4 it is hard-coded. The code which does this
(in CGIServlet) looks like this:

try {
  var=3DSystem.getenv("SystemDir");
} catch (Throwable t){}
if(var=3D=3Dnull) var=3D"c:/winnt";

The problem is that Sun has introduced getenv() in JDK
1.2, then deprecated it in 1.4 and then un-deprecated
it in 1.5 and now recommends this to pass the
environment to the sub-process.

In other words there is no reliable way to ask for the
value of SystemDir in java.

I think it is possible to read the registry from
jdk1.4.  But this will not work either if the registry
key (which one?) is missing.

I have re-opened the ticked.


As a workaround please use Apache/Php/PhpJavaBridge
and Tomcat/mod_jk connector. This is described in the
INSTALL instructions and in the README.  This is also
much faster than calling CGI programs or native code
from java.
