Exception while communicating with Nuxeo Automation Server
I have nuxeo DM 5.5 up and running at http://localhost:8080/nuxeo/site/automation I am trying to access Nuxeo EP 5.5 Automation server from Nuxeo Java automation client as under:
public static void main(String[] args) throws Exception {
HttpAutomationClient client = new HttpAutomationClient(
"http://localhost:8080/nuxeo/site/automation");
Session session = client.getSession("Administrator", "Administrator");
Documents docs = (Documents) session.newRequest("Document.Query").set(
"query", "SELECT * FROM Document").execute();
System.out.println(docs);
client.shutdown();
}
But, the above code giving me the following exception:
java.lang.RuntimeException: Cannot execute {Content-Type=application/json+nxrequest, Accept=application/json+nxentity, */*, Authorization=Basic QWRtaW5pc3RyYXRvcjpBZG1pbmlzdHJhdG9y}

I just took the same example (modified slightly) and ran without issue against an existing 5.5 repository using Administrator credentials. If you paste the Automation server URL into a browser command line, enter credentials, can you then download and open the resulting JSON? Is there any chance it's a rights issue? Do you have all the required libraries on the build path? Here are the versions I used: httpclient-4.1.1, httpcore-4.1, nuxeo-automation-client-5.5-SNAPSHOT, ezmorph-1.0.4, json-lib-2.2.1-jdk15, mail-1.4.jar, jackson-mapper-asl-1.81, and jackson-core-asl-1.8.1 (actually the last two aren't mentioned in Nuxeo docs as dependencies but i did need them to get my example to work).
Anywhere here's the code I just created and used…
import org.nuxeo.ecm.automation.client.Session;
import org.nuxeo.ecm.automation.client.jaxrs.impl.HttpAutomationClient;
import org.nuxeo.ecm.automation.client.model.Documents;
public class testautomation {
public static void main(String[] args) {
String url = "http://192.168.5.115:8080/nuxeo/site/automation";
HttpAutomationClient client = new HttpAutomationClient(url);
Session session = client.getSession("Administrator", "Administrator");
Documents docs = null;
try {
docs = (Documents) session.newRequest("Document.Query").set(
"query", "SELECT * FROM Document").execute();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (docs != null)
System.out.println(docs);
else
System.out.println("No documents found");
client.shutdown();

Further, I had different lib versions as compared to yours, so I tried my example with your lib versions and it gave me this on my console:
The java class could not be loaded. java.lang.UnsupportedClassVersionError: (org/nuxeo/ecm/automation/client/jaxrs/impl/HttpAutomationClient) bad major version at offset=6
I think there must be some java version conflict. Bruce can you tell me which Java version are you using?
