hello, configure tomcat with mysql. BD was built correctly, but when I try to run the following example throws me the following error

try {  
final LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI();  
APISession session = loginAPI.login(“bonita”, “bpm”);  
ProcessAPI processAPI = TenantAPIAccessor.getProcessAPI(session);  
} catch (BonitaHomeNotSetException ex) {  
Logger.getLogger(ControladorIndex.class.getName()).log(Level.SEVERE, null, ex);  
} catch (ServerAPIException ex) {  
Logger.getLogger(ControladorIndex.class.getName()).log(Level.SEVERE, null, ex);  
} catch (UnknownAPITypeException ex) {  
Logger.getLogger(ControladorIndex.class.getName()).log(Level.SEVERE, null, ex);  
} catch (LoginException ex) {  
Logger.getLogger(ControladorIndex.class.getName()).log(Level.SEVERE, null, ex);  
}

I think I’ve solved the problem, place the first four lines and stop throwing error.

regards

Map\<String, String\> settings = new HashMap\<String, String\>();  
settings.put(“server.url”, “[http://localhost:8084](http://localhost:8084)”);  
settings.put(“application.name”, “bonita”);  
APITypeManager.setAPITypeAndParams(ApiAccessType.HTTP, settings);

```
    final LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI();
    APISession session = loginAPI.login("administrator", "bpm");
    ProcessAPI processAPI = TenantAPIAccessor.getProcessAPI(session);

```

Hello,  
Could you please help me understand where exactly did you have to add the above mentioned line?

I’m running into similar issue.

Thanks

TenantAPIAccessor is a Singleton that needs parameters to know how to connect to your Bonita platform before any API call can be made. Full documentation is available on this [page](https://documentation.bonitasoft.com/bonita/7.8/create-your-first-project-with-the-engine-apis-and-maven) .
