Make toolkit-based application runnable in an distributed environment

[dll]

Toolkit-based application fails to run in a distributed environment, e.g. when you set the <distributable/> tag in the web.xml deployment descriptor. This is actually happens, because violation of the web app spec - class WebApplicationContext? is used as a object that is put into http session, however, it does not implements the Serializable interface, causing web container or application server to fail. Ability to make web applications distributable is imprtant thing, as this allows to use load balancers and failover switches without duplicating http sessions as when <distributable/> tag is set, applicaiton server takes care of replicating the single HttpSesion? instance and its contents across cluster nodes.

I tried to fix ticket on my locl working copy by adding "Serializable" to the WebApplicationContext? class. I'll make a number of runs in our clustered environment, to ensure this is enough or to find out more places for fix. So I hope I'll be able to provide a patch for this issue on Monday.

P.S. Pardon for a lot of mistypes, it is kind a coldy day here in StPetersburg?, our dev team office is located on the sub-ground floor and my fingers got frozen a bit. %)

This issue ( #695 ) have been around for ages, but somehow we have always had more urgent things to look at. Patch would be great and will be integrated to trunk asap.
