Folks,
Are there any plans to tweak Drools to allow it to run in a security
constrained environment such as Google App Engine or Applets? I know some of
the other JBoss.org projects have this on the 'todo' list.
When I try to load a simple web application using drools into the Google App
Engine, I get the error below.The app itself is the sample 8 from the
following web page, but tweaked according to the Google 'howto' to get it up
and running in the app engine; http://code.google.com/p/red-piranha/
My understanding of the problem is that drools is using File access to check
if the configuration file exists the first time it is run. This is
constrained in App Engine - just like the J2EE spec says it should be
(although most other app servers allow you to get away with this!). I know
that if I tweak the source code there will be other points where similar
file access is required.
While not trivial, would it be possible to add a one-line check for that the
user has permission to do file.io before calling File.Exists (the
alternative , of catching and ignoring the AccessControlException is ugly!).
The hardest part of this is that the check would need to be added at
multiple points in the Drools source code.
Any thoughts / comments/ suggestions?

Does this File.exists() usage occur even if your DRL is a classpath
resource and fetched with getClass().getResourceAsStream()?

Geoffrey,
The stack exception below is Drools looking for the conf file *before* it
even looks for the DRL file. However *any* file IO is blocked - so even it
Drools got past the File.exists(), it's likely to throw another
SecurityException at the getClass().getResourceAsStream for the DRL file.
I say 'likely' as 3 months ago I was trying to get version 4 of Drools
running in an Applet environment (has similar security constraints), and
worked my way through the source code to resolve the security exceptions. In
that case, getClass().getResourceAsStream was blocked.
Any suggestions?
Thanks
Paul

Hi Paul,
As a temporary solution you could try to use AspectJ for this task (
http://www.eclipse.org/aspectj/). Sounds like an ideal fit for this problem.
It is a crosscutting concern after all.
You could use an around advice over the following pointcut:
call(public boolean java.io.File.Exists(..))
and simply return false. Then weave this advice to the Drools jars.
Best Regards,
Michal

I am not surprised that File.exists() fails, but why does
getClass().getResourceAsStream() fail?
In Applets, the latter should work:
http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html
chapter Using Images in a Swing Applet.
Because getClass().getResourceAsStream() only looks in the classpath,
I see not reason that Google App Engine would block it.

Geoffrey,
The stack exception below is Drools looking for the conf file *before*
it even looks for the DRL file. However *any* file IO is blocked - so
even it Drools got past the File.exists(), it's likely to throw another
SecurityException at the getClass().getResourceAsStream for the DRL file.
I say 'likely' as 3 months ago I was trying to get version 4 of Drools
running in an Applet environment (has similar security constraints), and
worked my way through the source code to resolve the security
exceptions. In that case, getClass().getResourceAsStream was blocked.
Any suggestions?
Thanks
Paul

Folks,
Are there any plans to tweak Drools to allow it to run in a
security constrained environment such as Google App Engine or
Applets? I know some of the other JBoss.org projects have this
on the 'todo' list.
When I try to load a simple web application using drools into
the Google App Engine, I get the error below.The app itself is
the sample 8 from the following web page, but tweaked according
to the Google 'howto' to get it up and running in the app
engine; http://code.google.com/p/red-piranha/
My understanding of the problem is that drools is using File
access to check if the configuration file exists the first time
it is run. This is constrained in App Engine - just like the
J2EE spec says it should be (although most other app servers
allow you to get away with this!). I know that if I tweak the
source code there will be other points where similar file access
is required.
While not trivial, would it be possible to add a one-line check
for that the user has permission to do file.io <http://file.io/>
<http://file.io <http://file.io/>> before calling File.Exists
(the alternative , of catching and ignoring the
AccessControlException is ugly!). The hardest part of this is
that the check would need to be added at multiple points in the
Drools source code.
Any thoughts / comments/ suggestions?

In Applets, the latter should work:
http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html
chapter Using Images in a Swing Applet.
Because getClass().getResourceAsStream() only looks in the classpath,
I see not reason that Google App Engine would block it.

Paul,
Have you managed to get it running? I did some changes to
ChainedProperties.java and managed to get it working but sincerely I dont
know if I broke something (that I could not detect in my humble tests).
But there is one thing that I guess will never work (unless GAE whitelists
more stuff) that is using time constraints on events cause it ends up trying
to use ScheduledThreadPoolExecutor.
best regards,
Rafael Ribeiro
I've attached my
http://old.nabble.com/file/p26283304/ChainedProperties.java
ChainedProperties.java modified file.
