I don't know how helpful this will be but I have tried to work around
the sas-java problem for weeks until I found a solution that worked;
but it's tedious, doesn't work everytime, and is a general headache to
get what you want, so take this solution lightly until sas-java figure
out a better solution.

What I did was follow Ronald Fehd's advice in trying to edit the sas
configuration file (here is his link: http://www.sascommunity.org/wiki/Java_JRE_1.5
). Unfortunately, this wasn't working at all. My problem was that I
had sas-java working on one machine at home, but not in the office. My
IT department is a pain to deal with, so what I tried was copying the
sas configuration file from home and replacing it over the one at
work. The only difference was in the part that Fehd mentions on the
JREOPTIONS.

So then what I did next was try to copy/paste the java folder from
home (it contained three JRE versions: 12, 22, and JRE6). When I
pointed the JREOPTIONS to the JRE6\bin\client\jvm.dll file, sas would
recognize JVM but then I got the same error you did when I tried to
actually use it for something important (like creating ROC curves
through PROC logistic).

So what I tried next was pointing the JREOPTIONS to the JRE1.5.0_12\bin
\client\jvm.dll file but then sas would return to giving me the same
java virtual machine could not be loaded error.

Finally, I tried this:

close SAS.
edit sas configuration file in nls\en\sasv9.cfg file
point JREoptions to java1.5.0_12\bin\client\jvm.dll
save configuration file
open sas
create new script > test per Fehd's method: %put
%sysfunc(getoption(JREOPTIONS));
make sure that the result is the same JREOPTIONS I edited (particular
w.r.t. location of the jvm.dll file)
test java > "proc javainfo; run;"
IF THIS WORKED, I OPEN MY SAS CODE I WANT TO RUN
RUN CODE
GET RESULTS!! YESSSSS!!

Unfortunately, once I close sas, the problem goes back to jvm could
not be loaded. So.... I have to do that process above everytime I want
to use jvm. :*(

If you can figure out a better solution, please post it.
