TestLink integration for test automation (Java, XML-RPC, Eclipse) - testing

Question

I am currently writting Java Program to execute tests and push the results on a testlink. I am using TestLink 1.9.14 and following site like :
http://ursshivy.blogspot.fr/2014/03/selenium-automation-testlink-api.html.
So I would like to do :
TestLinkAPIClient apiClient = new TestLinkAPIClient(ACCESS_KEY,TESTLINK_SERVER_URL);
apiClient.reportTestCaseResult(TESTLINK_PROJECT_NAME, TESTLINK_TESTPLAN_NAME,testCaseID, BUILD_RELEASE_NAME, executionNotes, result);
With theses packages :
testlink-api-client-2.0.jar
commons-logging-1.1.jar
junit.jar
ws-commons-util-1.0.2.jar
xmlrpc-client-3.1.jar
xmlrpc-client-3.1-sources.jar
xmlrpc-common-3.1.jar
xmlrpc-common-3.1-sources.jar
TestLink seems to be not really available (API for exemple, so I tried already 3 different version of the API).
I google for a long time and tried something. So I tried to modify the xml-rpc file in the TestLink folder, I tried different .JAR and another version of TestLink (1.9.12). For the moment, I get this message :
Exception in thread "main" testlink.api.java.client.TestLinkAPIException: The call to the xml-rpc client failed.
