Integration

I am new to the world of SOA, ESB, and BPEL and am starting with something simple such as reading a file from one directory performing a data transformation and writing the file to a different directory. I understand that Oracle's ESB and BPEL are very similar in functionality. I have successfully been able to read files in using a file adapter and listener in BPEL. When I try to set up a new ESB application with a file adapter and listener in ESB, I register the project with the Integration Server without any problems, and am able to see all components in the ESB Control. When I drop a new file into the directory that the adapter is attached and listening to, nothing happens. The file is not picked up and there are no new instances of any ESB services. Am I missing something? Is there a log that could be checked to see if the service is even checking the directory?

Along the same lines, I am wondering if there is an easy way to update the directory that is being listened to once the service has been registered/deployed (with either ESB or BPEL). Is there a config file that someone other than a developer could update without having to redeploy the service again.

Any help would be greatly appreciated. Thanks.
