newbie question...please help re:image processing servlet with tomcat

[Adam Jenkins <ad...@hotmail.com>]

Hi,

I'm relatively new to tomcat 3.1...I'm having a problem with a simple image 
create servlet from jason hunters java servlet programming page 161...the 
servlet returns a hello world gif by using g.drawString where g = 
image.getGraphics() then encodes using Acme GifEncoder...the code works fine 
stand alone and applet but as a servlet in tomcat I keep getting an 
UnsatisfiedLinkError no fontmanager found in java.library.path   I have set 
LD_LIBRARY_PATH to point to the directory that contains fontmanager.dll and 
even set java.library.path to point to it in runtime, but I still get the 
same error.  I'm using tomcat on win32

is there something I'm missing here?  Has anyone come across this kind of 
thing before.

thanks in advance
adam

Hi!

Some sharing in Linux platform might give you some insight.
AWT as well as image stuff use X (you may think it is the console window). If
tomcat is run as background without login (start as service or whatever), X is
not accessible. It may be similar in Windows. To test for it, simply start
tomcat manually in command prompt instead of service.

Hope this help.
