Integrating Agrest in Tapestry app
Does anyone have experience integrating Agrest (https://agrest.io/) into
a Tapestry app? My Tapestry app uses Cayenne ORM and it looks like
Agrest works well with Cayenne to produce REST functionality. It would
be helpful to see some sample code.
Thanks in advance
Tim

Hi all
In case you want to follow the topic I posted some comments on the
issue that Tim reported on GitHub.
https://github.com/tynamo/tapestry-resteasy/issues/19
Cheers!

Thanks for your help Ben. I guess I don't need to use agrest. I can use
tapestry-resteasy with cayenne persistence.

Re: Integrating Agrest in Tapestry app
Posted by Ben Weidig <be...@netzgut.net>.
Hi Tim,
your code looks fine to me, but it seems like this is a limitation of
tapestry-resteasy.
The project wraps the configuration of RESTEasy to make it easier to use
with Tapestry.
The method
https://github.com/tynamo/tapestry-resteasy/blob/0111a37e842a67e49b47752de85d738676c179e9/src/main/java/org/tynamo/resteasy/ResteasyRequestFilter.java#L138
goes over the contributed instances and classes, but it doesn't support all
the available types RESTEasy has to offer, so it throws the exception
you're getting.
Only Resources and Providers are supported, but AgRuntime is a "Feature"
type.
The only option I see (without tapestry-resteasy adding it) is overriding
the ResteasyRequestFilter and extending the conditions for provider
detection to allow instances of Feature, too.
Features are internally registered like providers if I saw it correctly in
the RESTEasy code.
I've only read the tapestry-resteasy/RESTEasy source code and not tested it
with a running project, so it might not be that easy.

Re: Integrating Agrest in Tapestry app
Posted by D Tim Cummings <ti...@triptera.com.au.INVALID>.
Hi Ben
I followed your suggestions and was able to get rest working with
tapestry-resteasy without using persistence. However when I added agrest
tapestry resteasy threw an exception unknown class type:
io.agrest.runtime.AgRuntime. My code is as follows. I am using a simple
data model from https://github.com/agrestio/agrest-bookstore-example .
Could you please check I have implemented your suggestions correctly.
- add tapestry-resteasy to your project
<dependency>
<groupId>org.tynamo</groupId>
<artifactId>tapestry-resteasy</artifactId>
<version>0.7.0</version>
</dependency>
- write a service to setup the AgRuntime
public class AgrestServiceImpl implements AgrestService {
public AgrestServiceImpl() {
ServerRuntime runtime = ServerRuntime.builder().addConfig("cayenne-project.xml").build();
AgCayenneModule cayenneExt = AgCayenneBuilder.build(runtime);
agRuntime = new AgBuilder().module(cayenneExt).build();
}
private AgRuntime agRuntime;
public AgRuntime agRuntime() {
return agRuntime;
}
}
- write a simple resource with a single @GET method using Agrest
@Path("/category")
@Produces(MediaType.APPLICATION_JSON)
public class CategoryResource {
@Context
private Configuration config;
@GET
public DataResponse<Category> getAll(@Context UriInfo uriInfo) {
return Ag.select(Category.class, config).uri(uriInfo).get();
}
}
- contribute the AgRuntime and resource like in my previous mail.
@Contribute(javax.ws.rs.core.Application.class)
public static void configureRestProviders(Configuration<Object> singletons, AgrestService svcAgrest) {
singletons.add(svcAgrest.agRuntime());
singletons.addInstance(CategoryResource.class);
}
- test it with your browser or curl
http://localhost:8089/tapestry-agrest/rest/category
java.lang.RuntimeException: Exception constructing service
'ResteasyRequestFilter': Error invoking constructor public
org.tynamo.resteasy.ResteasyRequestFilter(java.lang.String,org.slf4j.Logger,org.apache.tapestry5.http.services.ApplicationGlobals,javax.ws.rs.core.Application,org.apache.tapestry5.ioc.services.SymbolSource,boolean,org.apache.tapestry5.ioc.services.UpdateListenerHub,long,long,boolean)
throws javax.servlet.ServletException: Application.getSingletons()
returned unknown class type: io.agrest.runtime.AgRuntime

tapestry-resteasy is just bringing RESTEasy to Tapestry.
There's no dependency to JPA/Hibernate.
Do you mean the PersistenceService in the example on the page under "Code
your singleton resource"?
That's not a necessity, just an example for a Rest resource.
In your case, you would use Agrest instead.
You don't need to edit web.xml because tapestry-resteasy uses a Tapestry
HttpServletRequestFilter to piggyback Tapstry itself, instead of going
through the a custom servlet defined in the web.xml.
Everything that would be done in the web.xml is done with code instead.
This way, you don't need an extra Bridge to handle service injection.
https://github.com/tynamo/tapestry-resteasy/blob/master/src/main/java/org/tynamo/resteasy/ResteasyRequestFilter.java
The next steps for simple proof-of-concept would be something like this:
- add tapestry-resteasy to your project
- write a service to setup the AgRuntime
- write a simple resource with a single @GET method using Agrest
- contribute the AgRuntime and resource like in my previous mail.
- test it with your browser or curl
Hope this helps!

Thanks Thiago and Ben for your great responses. I am working through
these suggestions at the moment.
I thought I would build a fresh tapestry app based on the quickstart and
introduce tapestry-resteasy and agrest.

tapestry-resteasy doesn't rely on either Hibernate or JPA nor any other
ORM:
https://repo1.maven.org/maven2/org/tynamo/tapestry-resteasy/0.7.0/tapestry-resteasy-0.7.0.pom

I don't think it's needed either. I guess you're confusing the code
examples with requirements.

That's correct. tapestry-resteasy it takes care of telling
Tapestry-the-page-framework to not handle requests to the REST URLs while
also handling these URLs inside Tapestry (either as an RequestFilter or an
HttpServletRequestFilter). Tapestry itself is implemented as a servlet
filter receiving all requests, even though it may not actually provide the
response for all of them.

Thanks for this very detailed reply. I will work through what you have
suggested and see how I go.
I had a look at tapestry-resteasy but it seems to rely on hibernate or
jpa and I am using cayenne. I am not sure what is required for
org.tynamo.services.PersistenceService. Also tapestry-resteasy says I
don't need to edit web.xml.
Another example I am following says I do need to edit web.xml.
https://github.com/andrus/wowodc13 is an example for tapestry and
cayenne and jersey 1.x rest. It seems to rely on a JerseyTapestryBridge
[1] but the code looks specific to jersey 1.x and wouldn't work with
jersey 2.x
Cheers
Tim

Re: Integrating Agrest in Tapestry app

Hi Tim,
full disclosure: I haven't used Cayenne or Agrest, but I checked out their
documentation.
I don't think there's anything Tapestry-specific needed to get it up and
running except setting up Rest.
They say in their docs that you still have to write your JAX-RS endpoints
and do security yourself.
For JAX-RS, there's tapestry-resteasy
https://www.tynamo.org/tapestry-resteasy+guide/
There are examples how to add Rest to Tapestry and register your resources.
The AgRuntime should be contributable just like a Rest resource. RestEasy
treats many of its classes are contributable (Resources, Provider, etc.).
You could create a service to build it.
@Contribute(javax.ws.rs.core.Application.class)
public static void configureRestProviders(Configuration<Object> singletons,
YourAgRuntimeBuilder builder) {
singletons.add(builder.build());
singletons.addInstance(YourCredentialsInterceptor.class);
singletons.addInstance(YourResource.class);
}
For security, we use custom headers containing an API key/secret that are
validated by a javax.ws.rs.container.ContainerRequestFilter with
@Priority(Priorities.AUTHENTICATION) and
@Priority(Priorities.AUTHORIZATION) and plug in your security code.
But as said before, I haven't tested it, and it just looks this way to me
at first glance.
Cheers,
Ben
