Re: [xmlblaster] Fail Safe for Applets - How?

Hi Marcel,

I spent alot of time thinking about this fail safe stuff. I'm not an experienced java programmer
by any means so how would I go about writing a wrapper class that will do the reconnect? I mean,
what are the steps involved in doing this?

What I was trying to do previously is when the exception is thrown (because the connection went
down), I called a method which would go and try to do a connect. Then I would check isConnected to
see if true and if not wait a while and try again.

Am I on the right track here?
