I am using the javax.xml.soap
API (javax.xml.soap.SOAPConnectionFactory
, javax.xml.soap.SOAPConnection
, and friends) to make a web service call to a remote server, for the most part with great success.
However, sometimes there is a problem and the program gets stuck reading forever.
To address this, I'd like to add a read timeout.
I found several ways it might be possible to achieve this, but they all seemed pretty bad.
So my question to the community is: What is the best way to implement a read timeout behaviour when using the javax.xml.soap API to make a call?
We have two timeout parameters: CONNECTION_TIMEOUT - sets max connection time to web service (milliseconds). SO_TIMEOUT - sets read\write time on web service. It is the time to complete a request and response cycle.
You need to cast your port object to a BindingProvider and then retrieve the request context, which is a Java Map of key/value pairs. Then, you set the connect and read timeout properties to whatever values you wish to use - this is specified in milliseconds.
request timeout — a time period required to process an HTTP call: from sending a request to receiving a response. connection timeout — a time period in which a client should establish a connection with a server. socket timeout — a maximum time of inactivity between two data packets when exchanging data with a server.
You have to create your own URLStreamHandler so that you can set URLConnection parameters like connection timeout and read timeout.
SOAPConnection connection = SOAPConnectionFactory.newInstance().createConnection();
URL endpoint =
new URL(new URL("http://yourserver.yourdomain.com/"),
"/path/to/webservice",
new URLStreamHandler() {
@Override
protected URLConnection openConnection(URL url) throws IOException {
URL target = new URL(url.toString());
URLConnection connection = target.openConnection();
// Connection settings
connection.setConnectTimeout(10000); // 10 sec
connection.setReadTimeout(60000); // 1 min
return(connection);
}
});
SOAPMessage result = connection.call(soapMessage, endpoint);
I have removed some try/catch for clarity.
import com.sun.xml.internal.ws.client.BindingProviderProperties
public someResponse callWebService() {
MyPort port = new Service().getPort();
Map<String, Object> requestContext = ((BindingProvider) port).getRequestContext();
requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, 10 * 1000); //10 secs
requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, 1 * 60 * 1000); //1 min
return port.someWebMethod();
}
