I have a program in a different server but i need to acces some of the API-s of the bonita engine. How can i do that?
I already tried:
parameters.put("server.url", "http://URL:PORT");
parameters.put("application.name", "bonita");
APITypeManager.setAPITypeAndParams(ApiAccessType.HTTP, parameters);
org.bonitasoft.engine.api.APIClient apiClient = new APIClient();
apiClient.login("user", "password");
But I always get some error like:
[org.apache.juli.logging.DirectJDKLog] [http-nio-8888-exec-1] [175] [ERROR] Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.reflect.UndeclaredThrowableException] with root cause

I already modified the code a little:
parameters.put("server.url", "http://localhost:1664");
parameters.put("application.name", "bonita");
APITypeManager.setAPITypeAndParams(ApiAccessType.HTTP, parameters);
LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI();
if (loginAPI == null) System.err.println("A login null");
else System.err.println("van login api");
//System.err.println(loginAPI.);
APISession apiSession = loginAPI.login("walter.bates", "bpm");
org.bonitasoft.engine.api.APIClient apiClient = new APIClient(apiSession);
System.err.println(apiClient.getIdentityAPI().getNumberOfUsers());
This works fine, however if i try another (working bonita) url I get this error:
java.lang.reflect.UndeclaredThrowableException

Are the client and the server using the same Bonita version ?

To be honest i didnt check the code that uses the API (my coworker wrote it) , but the installed bonita with the studio, that i can access with localhost has the same version as the one on the server.
In localhost i can access the APIs with the code, but if it is on a remote server, then i get the exception.
We are using version 7.9

Does the remote server has enabled the[HTTP servlet](https://documentation.bonitasoft.com/bonita/7.10/configure-client-of-bonita-bpm-engine#toc4) to use the Java API in HTTP ?

Well, if i remember correctly 2-3 days ago we tried to enable it, this was commented in web.xml in the bonita folder of the servers webapps:
\
\HttpAPIServlet\
\org.bonitasoft.engine.api.internal.servlet.HttpAPIServlet\
\
Now it is not but still get the error.
It is not that urgent, because we used a different aproach but it would be nice if this could work.
