MailMan integrated with JSP/Servlet integration

[michela rossi]

Hi,
Wonder if anyone can help me. 

I have a client for whom we are building a website using J2SE & TOMCAT
4.1.7. (at clients request). The client also has an installation of
MailMan that they would like us to use to validate registered users.

All well and good, but given that the bulk of the websites code will
be written using Java, and MailMan is written in Python - this seems
to represent a problem or two : e.g. how will the Java code
interrogate the MailMan installation to find out whether a user has
validated correctly? Is there any kind of Java interface that anyone
knows about?

Any help would be most welcome,
Thanks, Michela.
