[Mapserver-users] java mapscript getPoints is already defined error

[Mario Basa]

Hello,

Has anybody had any success with JavaMapScript in a servlet/tomcat 
environment. I made a simple servlet and did some tests on it using 
JMeter, and the application usually dies when around 5 concurrent 
threads try to access it. I tried synchronizing the class that contains 
the MapScript and also the SingleThreadModel but the application still dies.

Regards.

mario.
