Unable to write String from Web form to a file

[anuapmd]

I created a simple text box

<form action="write">
	Input a String <input type="text" name="data" />
	<br/><input type="submit">
</form>

This is the integration.xml

<int:channel id="input">
		<int:interceptors>
			<int:wire-tap channel="logger"/>
		</int:interceptors>
	</int:channel>
	
	<int:logging-channel-adapter id="logger" level="DEBUG"></int:logging-channel-adapter>
	<int-file:outbound-channel-adapter auto-create-directory="true" directory="file:/output" channel="input"></int-file:outbound-channel-adapter>

and this is my controller

@RequestMapping("write")
	public void write(@RequestParam("data") String data){
		ApplicationContext ctx=new ClassPathXmlApplicationContext("integration.xml");
		MessageChannel channel= ctx.getBean("input",MessageChannel.class);
		channel.send(MessageBuilder.withPayload(data).setHeader(FileHeaders.FILENAME, "myfile.txt").build());
	}

but no directory is being created. Where am i wrong?

Thanks

I suggest you run with DEBUG logging and follow the message through your app.
