AWS-Component (S3) => Best way to set the CamelAwsS3Key Header?

[megachucky <me...@googlemail.com>]

Hello.

Again a question about the AWS component (S3). What is the best way to set
the CamelAwsS3Key header?

I did it this way:
from("file:files/inbox").setHeader(S3Constants.KEY, simple("Static
Key")).......

The test in the source code does this:

        Exchange exchange = template.send("direct:start",
ExchangePattern.InOut, new Processor() {
            public void process(Exchange exchange) throws Exception {
                exchange.getIn().setHeader(S3Constants.KEY,
"CamelUnitTest");
                exchange.getIn().setBody("This is my bucket content.");
            }

If the key is null, then the following is called in the camel aws code:
throw new IllegalArgumentException("AWS S3 Key header missing.");

Thus, I have to set a key (of course it must not be null due to the S3
service!). 
Nevertheless, I also managed to do it automatically: In my first try, the
key was message1.xml and message2.xml -> I did not set a header. The name of
the files was used.

Unfortunately, I cannot reproduce this. Italways get the exception, if  I do
not set the header. Can you please help me out? What is the configuration
that the header is set automatically?

Thank you...

Best regards,
Kai

It doesn't look like there is an automatic way of setting the S3 key, so
I'm not sure why it worked the first time.

I think what you're trying to do would be this:

Message in = exchange.getIn();
in.setHeader(S3Constants.KEY, in.getHeader(Exchange.FILE_NAME));
