Hi Jerome,
As you said, there are sevral ways to solve the problem with Restlet and I
found another way to make it works (maybe not the easiest). Basically I
created a class extending from ServerResource and an application. In the
application, I use a certain configuration of the router :
router.attachDefault(FtpResource.class).setMatchingMode(Template.MODE_STARTS_WITH);
In the resource, I parse the representation returned by the FTP server using
a pattern ( private static final Pattern pattern =
Pattern.compile("[drwxs-]{10}");).
When my response matches with the pattern, it means that my response is a
contain of a FTP directory otherwise the response is a file.
In the case where the response is a contain of a FTP directory, I build a
referenceList. From this referenceList, I apply some representations (HTML,
text/uri-list).
In the case where the response is a file, I return the file.
It will be nice that the directory class can support the browse through a
FTP site.
Best regards,
J-Christophe
