WebServiceTemplate has a bad way to createConnection

[honnom]

When using WebServiceTemplate to send soapmessage to a same uri,every time it creates a new WebServiceConnection .
So if i send 10000 times soap message to a same uri 'http://localhost:8080/echo/echoService',the method createConnection() is invoked 10000 times.
But i want it just invokes the method createConnection() one time ,not 10000 times.
Is this the WebServiceTemplate bug ?

the WebServiceTemplate code is :
connection = createConnection(URI.create(uriString));

	public Object sendAndReceive(String uriString, WebServiceMessageCallback requestCallback,
			WebServiceMessageExtractor responseExtractor) {
		Assert.notNull(responseExtractor, "'responseExtractor' must not be null");
		Assert.hasLength(uriString, "'uri' must not be empty");
		TransportContext previousTransportContext = TransportContextHolder.getTransportContext();
		WebServiceConnection connection = null;
		try {
			connection = createConnection(URI.create(uriString));// <--- this is here
			TransportContextHolder.setTransportContext(new DefaultTransportContext(connection));
			MessageContext messageContext = new DefaultMessageContext(getMessageFactory());
			
			return doSendAndReceive(messageContext, connection, requestCallback, responseExtractor);
		} catch (TransportException ex) {
			throw new WebServiceTransportException("Could not use transport: " + ex.getMessage(), ex);
		} catch (IOException ex) {
			throw new WebServiceIOException("I/O error: " + ex.getMessage(), ex);
		} finally {
			TransportUtils.closeConnection(connection);
			TransportContextHolder.setTransportContext(previousTransportContext);
		}
	}

This is maybe a bug.

Hi

If you trace down the execution, you'll see what exactly createConnection() does. In case of commons-httpclient it will you this library's infrastructure (e.g. org.apache.commons.httpclient.MultiThreadedHttpCon nectionManager class) which you can find great documentation about at http://hc.apache.org/httpclient-3.x/performance.html).

Generally connections are reused and configured in Spring XML for commons-httpclient beans.
