Jython saying "No visible constructors for class"

I have a jython servlet as part of a large application running in tomcat5. I 开发者_JS百科tested a few Spring Framework classes and create the objects in the Jython servlet. When I try to create objects of classes in the application I catch an Exception message "No visible constructors for class". These java classes do have a public constructor class, such as:

public SchoolImpl() { }

I create the object in python:

from com.dc.sports.entity import SchoolImpl

...

school = SchoolImpl()

What am I doing wrong?

doublep / cluch answered the question :-) in the comment

adding just a little info:

From the Jython FAQ :

3.3 Why can't I execute a 'protected' or 'private' Java instance method or access a 'protected' or 'private' attribute in a Java package?

By default, as in Java, these methods are protected from external access. Access to all Java fields and methods can be enabled with the python.security.respectJavaAccessibility registry setting:

# Setting this to false will allow Jython to provide access to
# non-public fields, methods, and constructors of Java objects.
python.security.respectJavaAccessibility = false
