I'm working to make client rest service with jasperserver to generate reports. I'm using the following code to make that:
I have problem in setting server url and report path,
for server url I put http://localhost:8081/jasperserver/
and as shown in next image I put report path rest/report/mytest/my_report
but I get 404 not found error in line
File remoteFile = resource.get(File.class);
So how can I get the proper report path from jasperserver?
public class App2 {
private final static String serverUrl = "http://localhost:8081
/jasperserver/";
private final static String serverUser = "jasperadmin";
private final static String serverPassword = "jasperadmin";

client.addFilter(new HTTPBasicAuthFilter(serverUser, serverPassword));
