Scheduling problem

[Nick Barrett]

Hi all, 

I'm wishing to use the scheduling loveliness to run some jobs on a periodic basis, but I'm having some basic configuration trouble. 

I've followed the documentation in https://github.com/bodar/utterlyidle/wiki/24.-Scheduling and so far, my features contain these resources:

@Override
public Resources addResources(Resources resources) throws Exception {
    resources.add(annotatedClass(BatchScheduleResource.class));
    return resources;

}

and my RestApplication contains these modules:

add(bindingsModule(bindings(extensions)));
add(new PortalComplianceFeatures());
add(new ScheduleModule());
add(new JobsModule());
add(new ProfilingModule());

 

but when I call http://localhost:8000/schedules/list

I get this: com.googlecode.yadic.ContainerException: interface com.googlecode.lazyrecords.Records not found in container

Oh, my bodar dependancies are:

<dependency>
    <groupId>com.googlecode.utterlyidle</groupId>
    <artifactId>utterlyidle</artifactId>
    <version>1.52</version>
</dependency>
<dependency>
    <groupId>com.googlecode.totallylazy</groupId>
    <artifactId>totallylazy</artifactId>
    <version>1.77</version>
</dependency>
<dependency>
    <groupId>com.googlecode.lazyrecords</groupId>
    <artifactId>lazyrecords</artifactId>
    <version>2.25</version>
</dependency>

Any ideas please?

Cheers, Nick

Nick,

you need to write a custom module to stick an instance of Records
from the lazryrecords project in either request or application
scope. You can use MemoryRecords if you don't care about
persistence after process dies, or one of the other implementation
(SqlRecords) if you do care and want to persist to a database.

Take care,
Mike.

Hi Mike, long time no speak! Thanks for reply.

Yes, I began to do that by adding Records into Application scope but when I start my application I get:

Caused by: java.lang.NoClassDefFoundError: com/googlecode/totallylazy/predicates/Predicate

which sounds really strange as TL is already a project dependency….

I must be doing something really wrong here?

Cheers

No idea if it's this, but you may well be using incompatible versions of the stack.

Looks like you're using a 2. version of Lazy Records, and a 1. version of UI and TL.

I think Alex is right, for what its worth :)

Thanks Mike & Alex…

So, I adjusted the versions of the dependencies to be the latest (including pre-release). Previously I was using only the released versions and that didn’t work :-)

So now I have got over the class cast exceptions but I am still having trouble scheduling stuff  due to 400 Unsatisfiable Parameters

Scheduling seems to be configured okay as http://localhost:8000/schedules/list works okay -> {schedules=[], schedulerIsRunning=true}

But when I try and schedule something e.g. a post to this endpoint: http://localhost:8000/portal-compliance/instruction/2011788

Using http://localhost:8000/schedules/schedule/12345/1000/60/portal-compliance/instruction/2011788 -> 400 Unsatisfiable Parameters

Nearly there!….any ideas?

Cheers

Nick

Seems to be expecting your ID to be a valid UUID. Try posting to 

http://localhost:8000/schedules/schedule//de305d54-75b4-431b-adb2-eb6b9e546014/60/portal-compliance/instruction/2011788

If you run UtterlyIdle in debug mode it prints out exceptions encountered when trying to match the resources - Can be helpful in diagnosing the problem (that or debugging the binding matching).

[Alex Luker]

I messed up that URL - just replace 12345 with a uuid

[Nick Barrett]

Awesome Alex, thanks! 

Got that working now and have updated the scheduling part of the Wiki to help future people.

My remaining challenge is to be able to query the schedule and / or jobs and get JSON back. When I call:

application.handle(get("/schedules/list").contentType("application/json; charset=utf-8").build()

I seem to get HTML back which is not quite what I’m after. Can I pass my UUID job Id into some get method?

Jobs seems to give me back empty JSON array but there’s nothing in that as I’ve not created a job have I?

[Alex Luker]

It might be because you're using .contentType rather than .accepting("application/json") - You need to tell the server what you want back, rather than what you're sending.

[Nick Barrett]

Good point, but Actually that didn’t make any difference… when I print out the response to 

application.handle(get("/schedules/list").accepting("application/json").build()

I still get HTML:

[Alex Luker]

So it turned out that the JSON rendering wasn't registered for the schedules resource. What you were seeing was just the toString of a HashMap. I've pushed a fix to master, so if you upgrade to the latest it should be working. 

[Nick Barrett]

awesome Alex, I’ll give it  whirl….

Thanks again for being attentive :-)
