How can I log into bonita engine from external java application with APIClient?

Q&A
1

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

Is there something im missing?

 

Thank you!

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 ?

4

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

 

5

Does the remote server has enabled the HTTP servlet to use the Java API in HTTP ?

6

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:

<servlet>
        <servlet-name>HttpAPIServlet</servlet-name>
        <servlet-class>org.bonitasoft.engine.api.internal.servlet.HttpAPIServlet</servlet-class>
</servlet>

 

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.
