Ant: [Php-java-bridge-users] Adding a "null" session variable value

[Jost B. <jos...@ya...>]

Hi Jonathan,

Thank you very much for the bug report.  The non-j2ee
Session (please see
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/server/php/java/bridge/Session.java?rev=1.10&view=markup)
is currently backed by a Hashtable.  That must be a
HashMap, of course[1].

If you have the JavaBridge backend running in eclipse,
please change the line

    protected Hashtable map;

to

    protected HashMap map;

I will fix this bug for the official 2.0.8 release.

Please use $session->remove($var).  Please see
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/server/php/java/bridge/ISession.java?view=markup

The java_get_session() invokes JavaBridge.getSession()
which returns an ISession (see above).

The actual implementation is either the servlet's
HttpSessionFacade or our own Session.java, when the
backend runs outside of a standard j2ee environment.

Please see the interface ISession.java above.

That would be great. If you want to document the 10
ISession methods, we can give you CVS write account.

That's also a good idea.  But then we need someone to
maintain it.

[1] When we change from Hashtable to Hashmap, we must
do the synchronization ourselfs.  I guess that was the
reason why I've used a Hashtable...
