Thanks, Claus.
I should've mentioned that the body is a list of objects...
So unfortunately I can't use
exchange.getMessage().getBody().toString().length() as it's returning the full
text size of everything in the list.
I really didn't want to do any string manipulations in the processor... but
since there was an easy way to do it, I couldn't resist and did something like
the following, which now works perfectly:
.process(new Processor() {
public void process(Exchange e) throws Exception {
int num =
StringUtils.countMatches(e.getMessage().getBody().toString(), "CLASSNAME");
e.getContext().getGlobalOptions().put("NumThings",
Integer.toString(num));
}
})
BTW, if GlobalOptions isn't recommended, is there a better way to hang a value
on the CamelContext so the caller can see it?
Thanks again.
