graph reload without restart

[Nawaz Khursid]

Hi,
I have a running instance of otp in singleton context. I have generated a new graph.obj file with some changes in gtfs feed.
I would like to test the multi-graph feature with a single router context to use the dynamic reload feature.

In order to do so I followed the tutorial [1]. I modified the data-source.xml and application-context.xml accordingly and
my directory structure contain the correct place holder for Graph.obj file.

I am facing an issue on startup of otp[2] about JsonCallBackFilter bean initialization.

Kindly please let me know what is missing. I am update to master branch.

regards


Attached herewith are the configuration/context files.

Hello Nawaz,

Unfortunately that documentation on multi-graph feature is out of date,
and things work very differently now. I will update the wiki.
You don't need any special Spring configuration now, you can just
configure the graphService in data-souces as follows:

<bean id="graphService"
class="org.opentripplanner.routing.impl.GraphServiceImpl">
<property name="path" value="/var/otp/graphs/{}/" />
<property name="defaultRouterId" value="arbor" />
</bean>

the {} placeholder will be replaced with the routerId from the query
string, or the specified defaultRouterId if there isn't one provided in
the query string.

Dynamic reloading of graphs is not currently implemented, though there
are some provisions for it.
