Open Source Document Management System | OpenKM

Dear Community,

I am trying to get the following REST API call to work using the documentation (http://localhost:8080/OpenKM/services/r ... ment?_wadl) but am only getting a "415 Unsupported Media Type error", has anyone encountered the same problem or has a fix? Any help is highly appreciated!
Result:
* getaddrinfo(3) failed for Content-Type: application:80
* Couldn't resolve host 'Content-Type: application'
* Closing connection #0
curl: (6) Couldn't resolve host 'Content-Type: application'
* About to connect() to localhost port 8080

Here is the class what implements the webservice https://sourceforge.net/p/openkm/code/H ... rvice.java That means rename in this case should be simple url with query params http://localhost:8080/OpenKM/services/r ... mename.doc ( all parameters must be url encoded ).

"Content-Type: application/x-www-form-urlencoded" is not applicable to this call only comsumes xml or json, nothing else.
