HI, I want to install OpenFlow so that I can generate & add workflows in my project. Thanks for Your valuable suggestion.But I am specifically told to download & install ‘OpenFlow’ product of zope. Also a file named ‘expression.py’ does not exist in my OpenFlow-1.0.0 folder. My OpenFlow folder shows the following files & directories after installation – [test@test openflow-1.0.0]$ pwd /opt/zope/lib/python/Products/openflow-1.0.0 [test@test openflow-1.0.0]$ ls acinclude.m4 build-aux config.status udatapath debian m4 aclocal.m4 configure doc README.kernel autom4te.cache README.hwtables Makefile.am config.h configure.ac include bin config.h.in stamp-h1 controller INSTALL var boot.sh Makefile.in ChangeLog config.log sbin soexpand.pl COPYING tests utilities Lib share regress README third-party secchan Makefile I have downloaded openflow from http://www.openflowswitch.org/wp/downloads/. I think I have downloaded the wrong ‘OpenFlow’ software.

From where should I download ‘Openflow-1.1.0’ product that ships well with Zope2.11??

Thanks a lot!!
