ksoap2 issue java.net.ConnectException

问题

I am using kSoap2 for accessing soap web services. I am getting java.net.connectException while executing the below line

androidHttpTransport.call(Constants.SOAP_ACTION_GET_METHOD_NAME, envelope)

This is not happening always, but some of the times. Is this the problem with connection time out to the server? How to increase the connection time out in kSoap ? I googled, but can't find out the solution . Can anyone suggest me the solution to fix this error.

Logcat details follows:

How to increase the connection time out in kSoap ?

There still seems to be an open issue with HttpTransportSE ignoring the timeout value in some situations. See this related link.

However, a solution for this involved modification of the existing ksoap2 API.

Thanks to the developers at Lightsoftai you can now add timeout to HttpTransportSE using the following code:

Note : You can use ksoap2 API version 2.5.2 or greater for this

       /**
       * Creates instance of HttpTransportSE with set url
       *
       * @param url 
       *             the destination to POST SOAP data
       */
         public HttpTransportSE(String url) {
         super(url);
         }

       /**
      * Creates instance of HttpTransportSE with set url
      *
      * @param url
      *            the destination to POST SOAP data
      * @param timeout
      *               timeout for connection and Read Timeouts (milliseconds)
       */
       public HttpTransportSE(String url, int timeout) {
       super(url, timeout);
          }

You can download the jar file for the same from here.

Also refer ksoap never timeout.

Hope it helps.
