I am having more problems with the Axis stockquote code. The previous timeout settings worked for a while.

What did you set them to?


I get <no instance available> back at the browser page due to a timeout caused by the line of code
Float ret = (Float) call.invoke( new Object[] { symbol } );
not responding.


That sounds like the woadaptor Receive timeout is less than the java.net.whatever timeout you set before. The Java one should be less.


If you refresh the page I will trap the exception
<java.net.SocketTimeoutException>
and calmly inform the user that the stock quote service is currently unavailable.


How can I trap the first problem <no instance available> in the java code without the user having to force a refresh?

You can't. The first problem is reported by the woadaptor (e.g. the CGI or mod_webobjects). You can't have any control over that from your application. The thing to do is to adjust the timeouts relative to each other so that the socket timeout happens before the receive timeout.
