I'm working in Camel 2.9.1 and I'm having an issue with complex expressions.
I have an FTP endpoint that is working just fine. Dumps the file right where
I need it to be (mostly). The only problem is that it puts it into a
directory that is named ${header.externalID}, obviously because it's not
evaluating the complex expression and getting the value from the header.
I've tried almost every way I can could think of, but I always get the same
result:
to("ftp://{{placeholder}}/${header.externalID}";);
to("ftp://{{placeholder}}/${in.header.externalID}";);
to("ftp://{{placeholder}}/"; + header("${header.externalID}") );
to("ftp://{{placeholder}}/"; + header("externalID") );
to("ftp://{{placeholder}}/"; + simple("${header.externalID}") );
to("ftp://{{placeholder}}/"; + simple("${header.externalID}", String.class)
);
to("ftp://{{placeholder}}/"; + simple("${header.externalID}").getText() );
None of it works. I always end up getting the literal string. And in the
case of one of the simple cases, I even get a "Simple: " in the text. I've
checked and the externalID variable is definitely in the header. And just to
be 100% sure, I tried using a ${date:...} expression as well, and it didn't
evaluate that either. I asked my partner who's been working in Camel a bit
longer and he had no ideas either.
Is there something that I'm missing? I'm also not opposed to workarounds.
There's a processor() right before the to() that puts the value in the
header. If I could insert something in between the processor() and to() that
would help me out with this, I would definitely do it. I just want some way
to use the Camel FTP component and not create an entirely separate bean to
do the FTP work.
Thanks in advance.
