Re: [Jython-users] Jython not recognizing jars in tomcat webapps web-inf/lib

[Anthony E. <ae...@si...>]

Is your WAR packed or unpacked?  If they are unpacked then take a look 
at the PyServlet class in the Jython distribution.  This demonstrates 
how to add your libraries in the WEB-INF/lib directory to sys.

Unfortunately this won't work with packed WARs because the class loader 
only seems to support reading from the filesystem.  I am still looking 
for a way around this.  My last attempt was to replace the class loader 
with a custom class loader but I am not quite sure how Jython's class 
loading is supposed to work: my class loader implementation is actually 
trying to create a class from the package names.  Example: if I try to 
use the following class: org.foo.MyClass the classloader will first ask 
for the class org.  I am not sure what the classloader should return in 
this case.

Sincerely,
Anthony Eden
