By default, dcm4chee 2 accepts associations from any source (promiscuous mode). You can change this behavior and many other things from the jmx-console.
If you want to store images to dcm4chee, simply use a tool that implements DICOM StoreSCU.

DCM4CHEE is the default AETitle, 11112 is the default port. If your PACS is running, it should be listening there.
You will need a couple of test DICOM files, be aware that some of the ones that you can find on line lack a patient Id and DCM4CHEE fails to accept images without a patient ID by default. Some samples:
