  • 1.  WattEvaluationException when calling soapHTTP

    Posted Wed June 11, 2008 03:25 PM

    First: what is the default timeout value when invoking pub.client.soapHTTP?

    Second: I currently have a service executing every night making 30 back-to-back soapHTTP calls. Recently (for the past 2 consecutive nights), my service has failed on at least 1 or 2 of the outgoing soapHTTP calls.

    Day 1 - java.io.InterruptedIOException. Unrecoverable timeout!.
    Day 2 - [ISC.0088.0001E] SOAPException: [ISS.0088.9136] A WattEvaluationException was thrown by the XQL Query engine

    both of these were not true errors, because when i retried the same soapcall with the same data 10 minutes later, it submitted successfully. Nothing has changed in my code, nor on the target server.

    I realize I should have added Retry logic to the code now, on the soapHTTP call itself (perhaps retry every 5 minutes for a max of 3 times). But I’m also curious about the two different errors I received.

    What is a WattEvaluationException?

    Have you searched Advantage or the IS Errors document (can’t remember the exact name)?

    Too bad it doesn’t make much sense :frowning:
    Meanwhile, further research leads me to believe it indicates a ‘network connection hiccup’. I don’t understand why suddenly this is happening every night randomly on just one of my soapHTTP calls… but ok.

    Is my resolution to the code itself a wise strategy? To place the soapHTTP call within a Repeat-until-Success-with-maximum-of-3-tries-every-5-minutes?

    i appreciate the insight

    Putting your soapHTTP calls (or any other call to a remote application) inside a repeat block is a good practice.

    Any chance that a new backup job or other network intensive thing (on your side or the service provider’s) might be causing this?
