SocketTimeout Exception

[Amit Madhoriya]

Hi,
I am getting this exception while calling a webservice to collect the data from the server. In my I am tryin maximum of 3 times to collect the data. But sometimes code is taking more than usual time to do the updation and throwing this exception. I am not able to find out the reasons behind this.
It would be a great help if anybody can suggest me the reasons behind this.

I would guess that you have two options:

1. Refactor the web server so it collects and sends it back faster

2. Change the duration of the timeout on the client to either 0(no timeout) or something higher than it is right now.

Hi,
This exception is stalling the processing of the application at the point it is occuring. What can I do so that my application doesn't freeze, crash or hang because of this exception. Instead application should carry on processing the next functionality. Any idea will be helpful for me.

If you don't care that the exception occurred and want to carry on, then catch it at some point after the exception is thrown, and keep going.

At whatever point in your program that makes sense, put in a try/catch. In the catch you will likely want to make a note that it failed so whatever comes next during the execution, the program won't assume that it was successful.

If you could post code it would be easier to be more specific.

Hi,
Here is the method in which I am getting this exception. Application is throwing this exception while trying again after timeout. It is trying maximum of three times.

public KitDefinitionVO[] getKitData(final Integer loc,
            final String storeNumber, final Calendar lastPollDate)
            throws ApplicationException {
 
        DefinitionType[] kitDefArray = null;
        boolean tryAgain = false;
        int attempt = 0;
 
        // Call the service to download the kit definitions.
        do {
            attempt++;
 
            try {
                kitDefArray = getWebService().getKitData(
                        new KitRequest(storeNumber, lastPollDate.getTime()));
            } catch (final RemoteException e) {
                String message =
                    "Failed to call the kit definition Web service to get kit definitions."
                        + " Kit service URL: " + webServiceUrl.toString();
                LOGGER.error(message, e);
                tryAgain = RETRY && (attempt <= RETRY_MAX_ATTEMPTS);
 
                if (!tryAgain) {
                    throw new ApplicationException(e, message);//At this line it is throwing the exception
                }
 
                LOGGER.error("Going to retry kit definition Web service in "
                        + RETRY_WAIT_TIME + " milliseconds.");
                try {
                    Thread.sleep(RETRY_WAIT_TIME);
                } catch (final InterruptedException ignore) {
                    // Ignore.
                }
            }
        } while (tryAgain);
 
        return convertServiceResults(loc, kitDefArray);
    }

Whenever this exception is occuring ... the application is freezing and its not allowing next task in the list to run. I am not able to figure out exactly at which line I should catch the exception. Any suggestions will be helpful for me.

Hi Amit,

Do you see any error/exceptions in application logs while you get this?You may get some information in there. Also try to print full stack trace using print stack trace method.

You can also want to see the server logs and see for some errors

Hi,
Please provide some suggestion to my problem ... It will be helpful for me.

I've seen it happen that a web service will run (seemingly) forever in some instances.

You might investigate using a Stub to set a timeout property so that you can control how long it takes - very useful for testing.

Assuming you are using Axis 1 1.x...

If you are using Axis 2, then you'll have to Google that yourself. I've only used Axis 1
