I found no javac with the Nokia install disk. I installed j2sdk1.4.1_01 (J2SE) from java.sun.com. When using pjava.exe to test the Hello World app pjava fails not finding the class definition. When I test that pjava works with PowerMonitor it works. When I recompile PowerMonitor with j2sdk1.4.1_01/bin/javac PowerMonitor fails. What version, and where to get it, of javac must be used with pjava.exe?
