Hello Friends,

The presence of an distributable element indicates that a web application is "programmed" appropriately to be deployed into a distributable web container.

I did not understand the significance of the word programmed here. Does it mean the developer has ensured that all his session attributes implement the serializable interface, so that the container can safely migrate them.

If my web app's web.xml does not have this optional element present what does that mean in the above context. Does it mean it is not programmed appropriately to be deployed into a distributable web container.

Thanks,
Yogesh.

No. It may be appropriate to be deployed into a distributed environment, if you've been careful enough about concurrency issues. If you don't set the element in web.xml, it simply means that you're not releasing your application into a distributed environment.

Thanks Satou,

Could you throw some light on what type of concurrent issues you mean.

Thanks,
Yogesh

Threading issues, like using static members in servlets.
