Re: Using krysalis with Tomcat to output PDF barcodes

Hello Alexandre,

I've quickly done the same under JDK 1.4.2_03 on WinXP Pro using Tomcat
5.0.28 and it worked here. From what you write I can tell that you did
everything right. Unfortunately, I don't have time right now to install
JDK 1.3 and Tomcat 4.x on my notebook. I'll do that this evening (CEST)
and will report back to you.

It is probably a classpath problem. Maybe your Tomcat doesn't properly
set up the classloader hierarchy for the service lookup mechanism to
work. Would you please give me the exact version number of your Tomcat?
