Can't retrive message body

[mvackel]

Hello,

I'm trying my initial steps with Jboss ESB doing the Getting Started guide examples, but I couldn't change the basic action to retrieve the message body.

I've made a very basic action with this method:


public Message process(Message msg) {
System.out.println("Here 1..");
String aNames[] = msg.getBody().getNames();

System.out.println("Here 2..");
for ( String str : aNames )
System.out.println(str);

System.out.println("Here 3..");
System.out.println("=> " + msg.getBody().get("org.jboss.soa.esb.message.defaultEntry"));
System.out.println("=> " + msg.getBody().get("org.jboss.soa.esb.message.body.content.TextBody"));

System.out.println("Here 4..");
System.out.println("Body: " + new String((byte[]) msg.getBody().get(BytesBody.BYTES_LOCATION)));

Object body = msg.getBody().get();

System.out.println("Here 5..");
String sBody = new String((String) body);

System.out.println("Here 6..");
System.out.println("String Body: "+ sBody);

return null;
}

The output is the following:

13:40:11,725 INFO [STDOUT] Here 1..
13:40:11,725 INFO [STDOUT] Here 2..
13:40:11,725 INFO [STDOUT] org.jboss.soa.esb.message.defaultEntry
13:40:11,725 INFO [STDOUT] org.jboss.soa.esb.message.defaultEntry-set-stack
13:40:11,725 INFO [STDOUT] Here 3..
13:40:11,725 INFO [STDOUT] => [B@b0a165
13:40:11,725 INFO [STDOUT] => null
13:40:11,725 INFO [STDOUT] Here 4..
13:40:11,725 WARN [ActionProcessingPipeline] No fault address defined for fault message!
......

The main question is: How can I retrive the message body?

The process was interrupted at "Here 4.." but how can I get the error message, if any?

Thanks in advance,

This problem happens if the provider is a FileSystem (FS Provider). If so, to retrive the message, use something like:

System.out.println("Body: "+ new String( (byte[]) msg.getBody().get() ) );


BUT, if the provider is a JMS provider, use something like this:

System.out.println("Body: " + new String((String) msg.getBody().get()));

in this last case, if you use the former version, it issues an exception. WHY are the message bodies differente?

The default composer for the filesystem retrieves the contents and stores them in the message as a byte[]. This can easily be changed however, if you know that the contents are string rather than binary.

The default composer is LocalFileMessageComposer but you can add a property within the fs-listener element to override it.

<fs-listener ...>
 <property name="composer-class" value="XXX"/>
</fs-listener>
