I am learning to use ruby on rail to replace our old php based web
application.
I have one question: originally we have some web services developed in
java, and they are running on the jSoapServer (java based). If we
still want to use our java code at teh back-end. how to do it in ruby
on rail. or are there info in detail for them.
Look for information on the ActionWebServices plugin for Rails. This
plugin used to be built into Rails for interacting with SOAP web
services, but with the decision to promote REST as an alternative to
SOAP it was pulled out into a plugin and ActiveResource (REST client)
was added to the Rails core.
