Yes, I'm waiting for 3 of the 5 teams to provide permission to post their code (2 have already done so).

To tide you over while we wait for them, here's a link to the antichess tournament writeup:

Hi,

Will this year's website list the awards/teams and provide links to all the projects? Previous years have done that and I have really liked it. I would love to be able to play to some other people's implementations of Gizmoball.

Thanks,
Aseem

No, there will not.  The quality of most of the student tests for ps6, along with the time they required, made it infeasible to perform full cross-checking and to separate out incorrect tests from incorrect implementations for this pset.  In future terms we hope to improve this situation.

Will there be cross checker results for PS6?

The Properties object only has String keys and String values.
Note that
http://antichess.csail.mit.edu/api/net/antichess/ai/AiPlayerFactory.html#PROPERTY_TIMED_GAME
specifies string values.

How do you extract non-string objects/values from a Properties class?
For instance, how do we get the boolean timedGame from the gameProperties?

The exception trace is very clear: access was denied to a Property that JAXBContext was trying to read.  You can either add a '<security>' section in your JAWS file which asks for this permission, or else sign your applet and give it all permissions.

There seems to be some discussion of this at google "jnlp jaxb site:sun.com".

Did anyone else use JAXB?

We get the following error when we try to run Webstart:

Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.util.PropertyPermission javax.xml.bind.JAXBContext read)
   at java.security.AccessControlContext.checkPermission(Unknown Source)
   at java.security.AccessController.checkPermission(Unknown Source)
   at java.lang.SecurityManager.checkPermission(Unknown Source)
   at java.lang.SecurityManager.checkPropertyAccess(Unknown Source)
   at java.lang.System.getProperty(Unknown Source)
   at javax.xml.bind.ContextFinder.find(ContextFinder.java:269)
   at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:358)
   at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:323)
   at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:244)

It seems that JAWS has some issues with JAXB.  Any ideas why?  Is this because we didn't sign?

Thanks!

Jon
