How to test my modified OTP version?

Hi all,

I know this is probably a pretty silly question but I don't know how to proceed. I've never worked with such a big project and I'm getting lost trying to figure out how everything works by just looking at the code.

I already builded my own OSM map and I would like now to make my own modifications and see how changes take effect in the routing process. The question is that most of the stuff I want to modify are in the routing package (speeds, transportation modes, new vehicle definitions, ...). I compiled and packaged everything with maven but I don't know what files I actually need (or should deploy) in order to test my own version of OTP by using the browser, as in the examples provided. In the introductory guides only webapp and admin-webapp packages seem to be used but here is my question: how are routes computed? After having a look at those both packages I found out that the RESTful API is being used for this purpose but anyway I don't see any evidence of the routing package. What files are being used in all this process (user request, http routing responses,...). From my undersanding, once the user specifies the parameters in the UI, an http request should be triggered and the routing engine should do all the work (A* execution, result parsing), giving back an http response, which is at the end rendered back in the map to the user.

I would really appreciate your help.

Thank you in advance!

Are you building/modifying OTP in Eclipse? Have you got unmodified OTP
up and running? If you are using Eclipse WTP, any changes you make
should deploy automatically to the Eclipse-managed web servlet.

The api-webapp project contains code for a Java servlet (web server
plugin) built using Jersey. The REST endpoints defined in the servlet
create routing requests from your query parameters and pass the requests
on to the core routing code from opentripplanner-routing. The api-webapp
project has a dependency on the routing project, so Maven includes the
routing .jar in the WEB-INF/lib directory when it's assembling the
api-webapp WAR (an all-in-one zipped webapp you can deploy to a servlet
container like Tomcat).

That is right, but there is another layer: think of the api-webapp as a
REST frontend for the routing module, which does not speak HTTP itself.
Other components (like the analyst batch processor) can use the routing
code without going through the web API.

If you follow execution in the REST endpoints (subclasses of
RoutingResource.java, specifically Planner) you will reach PathService
in the routing project (via PlanGenerator).

Yes, I got it working after ignoring some Javascript errors and I set up the Tomcat server in Eclipse.

That's exactly what I wanted to know.

I will have a look. I think I'll be able to continue with my research with this info. Thanks!

Okay, my last message was deleted (maybe for attaching some files?) so I will try to sum up my current problem which I described in my last reply. I'm trying to deploy OTP in my fresh VM (Ubuntu Server 12.04 64-bit) but I'm having some problems with Tomcat. I'm getting no errors with graph building, package compilation/packaging so I assume everything is ok. I added the code mentioned in https://github.com/openplans/OpenTripPlanner/wiki/RunningTheWebappInTomcat in my Tomcat policy files so the graph file (located under /otp) should be able to be read (actually it is because if I use this graph in the 2-min example app it loads successfully). I'm using its directory in the path property in the data-sources.xml file and I didn't modify the application-context.xml file (by now, I didn't find any necessity for that). When deploying both opentripplanner-api-webapp and opentripplanner-webapp the first one can't be started. Here you are the errors displayed in the tomcat log file:
