[Zope-dev] Zope and java

Hello, I've just discovered Zope, and would like to get more information about it as it seems quite interesting . But I'm not sure I could use it for the web project I'm working on. First, I'd need to stock XML files in an object database like the one provided with Zope. What kind of requesting language may I use ? XQL ? Xpath ? XML-QC ? OQL ? XOQL ? Second question, is there a java API integrated in Zope ? If not, is it possible to interface Zope with others java products as Resine, servlet engines, EJB server...? Thanks in advance Bruno Faure
