SocketTimeOutException

[corwin42]

I just got a SocketTimeOutException in my app while parsing a http response inputstream.

Here the exception:

weatherupdater_hc_responsesuccess (java line: 189)

In the HC_ResponseSuccess sub I just initialize the SAX parser and parse the inputstream:

Sub HC_ResponseSuccess (Response As HttpResponse, TaskId As Int)
   sax.Initialize
   sax.Parse(Response.GetInputStream, "SAX")
[...]

What happend here? Wasn't the data copletely received? A part of the XML got parsed correctly but it seems that the rest is missing.

How can I prevent such an error? Do I have to put the sax.Parse(...) into a try..catch block?

The actual stream is only downloaded during parsing. You can increase the timeout value or better do it asynchronously (you may still need to increase the timeout value).
HttpUtils can help you if you want to do it asynchronously.

Thanks for the quick answer. I think I will switch over to asynchronously processing.
