Does RemoteApiOption method useServiceAccountCredential works with P12 file? - service-accounts

Question

Does useServiceAccountCredential works with P12 file. I am trying to use it in Java and get error com.google.appengine.repackaged.com.google.api.client.http.HttpResponseException‌​: 302 Found

Yes it does. You need to have an AppEngine app serving the remote API. E.g., you would have a python app, with the following lines in app.yaml:
- url: /remoteapi.*
script: google.appengine.ext.remote_api.handler.application
Or java app with the following in web.xml:
<servlet>
<display-name>Remote API Servlet</display-name>
<servlet-name>RemoteApiServlet</servlet-name>
<servlet-class>com.google.apphosting.utils.remoteapi.RemoteApiServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RemoteApiServlet</servlet-name>
<url-pattern>/remote_api</url-pattern>
</servlet-mapping>
Please note that depending on your client, it might call a bit different url, e.g. /remote_api
Also, if you have deployed the AppEngine app in a module, take that into account in the client code, you would have:
RemoteApiOptions raoptions = new RemoteApiOptions()
.server("my-module-dot-my-project.appspot.com", 443)
.useServiceAccountCredential("my-service-account-id", "my-p12-file.p12");
RemoteApiInstaller installer = new RemoteApiInstaller();
installer.install(raoptions);
Hope that helps!
