Spring Integration WS element <ws:inbound-gateway> available but <ws:header-enricher>

[AvinashMunaga]

This is a continuation thread to the issue in jira quoted
INT-2348.

Hi Artem,

The problem with<ws:header-enricher> is resolved as I replaced it with <header-enricher>. Going through with the example(ws-outboundgateway) the got another problem.

While sending message to the URL I am getting a Null Pointer Exception.

This is what my java class looks like:

public class SpringIntegrationDemo {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
				"blog/temperatureConversion.xml");
		ChannelResolver channelResolver = new BeanFactoryChannelResolver(
				context);

		// Compose the XML message according to the server's schema

		String requestXml = "<faernheitToCelsius xmlns=\"http://examples.csc.com\">"
				+ "	<farenheit>400</farenheit>" + "</faernheitToCelsius>";
		
                // Create the Message object
		Message<String> message = MessageBuilder.withPayload(requestXml)
				.build();

		// Send the Message to the handler's input channel
		MessageChannel channel = channelResolver
				.resolveChannelName("fahrenheitChannel");
		channel.send(message);

	}
}

This is my COnfig file

Hello
So, the main problem is here:

at org.springframework.integration.ws.DefaultSoapHead erMapper.extractUserDefinedHeaders(DefaultSoapHead erMapper.java:68)

Please, look at: https://jira.springsource.org/browse/INT-2294
The issue was fixed in the latest release - 2.1.0.RC2
Can you switch to this version?

Cheers,
Artem Bilan
