Issue2860

For some imports like this
from javax.xml.parsers import *
not all names are imported.
With jython 2.7.1 it worked and 
DocumentBuilderFactory
was available.
With jython2.7.2 it is not in my context.
I will try to add code to reproduce since on the REPL this works fine in 2.7.2

The fact it works in the REPL suggest we may still be dealing with a publication problem, at least if concurrency is involved.
Is this 2.7.2b3?
The other reason for missing classes might be a bug in the package cache. Giving one or more -v options to org.python.util.jython will tell you where it is looking for things, and if different in the REPL from the script, would provide perhaps the best clue.

Unfortunately the issue is not limited to "*"-imports.
Now I got some errors (Web-portal using Tomcat) like this:
from datetime import datetime
print datetime.now()
-> Attribute-Error datetime has no attribute "now"
I am using jython 2.7.2b2

I'm not able to reproduce this.
PS 272b2-trial> inst\bin\jython -V
Jython 2.7.2b2
PS 272b2-trial> inst\bin\jython -c "from javax.xml.parsers import *; print DocumentBuilderFactory"
<type 'javax.xml.parsers.DocumentBuilderFactory'>
PS 272b2-trial> inst\bin\jython -c "from datetime import datetime; print datetime.now()"

PS 272b2-trial> inst\bin\jython -c "from datetime import datetime; print len(dir(datetime))"
79
This last is the same as in the REPL. But it sounds like #2834, especially if we are in a servlet context (therefore possibly concurrent).
Could you try on 2.7.2b3 ?
