Green threads or Native threads????

[niraj l]

Hello,     I have a servlet application which is compiled using jdk1.2 . But the Jrun that I use has the java.exe variable (in jsm.properties) set to point to an executable in jdk1.2.1_02 .     When I try to run any of the servlets which are complied using jdk1.2, my Jrun blows off. It just stops running and I get "Jrun is busy . Too many concurrent users" error message.     Is it a threading issue ?     Do I have to explicitly compile my code using Jdk1.2.1_02 so as get all the threads as native rather than green_threads?   Please reply asap.... thanks, Niraj.
