Re: SpringBean router not discovering any routes
Give you bean an id in addition to the name.

Re: [1.1.3] Tomcat + RestletFrameworkServlet mapping SpringBeanRouter to /
Rhett,
I agree on the setAttachment semantics. I'd still like to see
something like the setDefaultAttachment method (e.g. setNoPath
attachment) without using the setAttachments method as it is a lot
simpler to configure. For all other cases the current router works fine.
Another option would be where you could specify a more regular
expresssion like pattern. You could then match this case using ^$ as
the path (i.e beginning and end of line with no content or to match /
and it would be ^/?$? Not sure how we'd get the template params in
there as java regex doesn't allow you to name groups of matches.

Thanks for the suggestion. I've added something similar in
SpringBeanRouter in trunk r4711, but I only added an attachments
property (a la SpringRouter).
Reasoning: I don't think that setAttachment makes sense as a bean
property, since it is actually adding another attachment instead of
replacing anything. Restlet's main Router class also has the concept
of a default restlet. The semantics in Router are a bit different
than what you have here (its default is the restlet that receives all
requests that don't map to something else, not the top-level resource
-- depending on the routing mode these might be different things),
so
I left it out. You should still be able to map the top-level route
using the attachments property like so:
property name=attachments
map
entry key=valuetopLevelResource/value/entry
/map
/property
I haven't tried this, though, so if it doesn't work please let me
know. (We can come up with a different property name if necessary.)
Thanks again,
Rhett

Re: [1.1.3] Tomcat + RestletFrameworkServlet mapping SpringBeanRouter to /
Jerome,
The one problem in the case I described is that it is not possible to use
as the resource path in this case as you cannot specify an empty bean alias
in the spring mapping file.
One approach around this would be to have a
SpringBeanRouter.setDefaultAttachment(String beanName) method which would
allow me to set the default restlet. Could you also have a
setAttachment(String path, String beanName) method and
setAttachments(ListString beanNames)
bean
id=router
class=...SpringBeanRouter
p:defaultAttachment=myRootResource
/
BTW setXXX methods are easier to work with in Spring than using methods such
as attach.

Re: Restlet 1.2 M2 released [throw previous email away]
Jerome, I would be happy if users can choose to either use the extensions or the mime-type where the extension is currently used. Consider a web service which is designed to be used either from a web browser when the media= parameter is used or from a Java client where the accept header can be set. In the documentation for this web service it would be useful to be able to list only the mime types. Rather than saying, if you use the media parameter use the keyword xhtml or if you use the accept header use application/xhtml+xml. Another thing to consider is if you describe your service using WADL you would be using the mime types so the client using the media= parameter would need to know the mapping to/from mime type to media type. i.e. you need a public extensions registry.

As you suggested filters do not work as they are completed before the response is sent to the client. 2. The ConnectorService also does not work as the afterSend method is only called if there was an entity and there were no IO exceptions in streaming the result to the client. The result of this that you will have dangling EntityManagers as they are not closed. What is required is an interceptor/filter which can wrap the entire call to the restlet chain which wraps the handle and commit calls. This would allow you to do setup before the restlet calls and cleanup after the response has been committed. The developer then can include a finally block so that the cleanup is also performed after any exceptions.

Re: Restlet WADL samples
Here is an example of adding parameters
protected void describePost(MethodInfo info) {
super.describePost(info);
info.addRequestRepresentation(new
Variant(MediaType.MULTIPART_FORM_DATA));
info.addRequestParameter(numRequests, false, xsd:long,
ParameterStyle.QUERY,
The number of requests to be processed in this Batch Job);
info.addRequestParameter(
inputDataContentType,
true,
xsd:string,
ParameterStyle.QUERY,
The MIME type of the input data specified by an inputData or
inputDataUrl parameter);
info.addRequestParameter(inputDataUrl, false, xsd:anyURI,
ParameterStyle.QUERY, The URL to the input data);
info.addRequestParameter(inputData, false, xsd:base64Binary,
ParameterStyle.QUERY, The inline input data);
}
So basically you override the method, call the super class version of the
method and then modify the object with your extensions.

For example, if I have a resource that can return HTML messages for errors

I've confirmed that this only occurs when using the built-in server

StringRepresentation the warning does not occur. When I switch to
Jetty the warning does not occur. And again, this only occurs for the
first request. Subsequent requests do not cause a warning to occur.
Here's the Groovy test case I've got it boiled down to:
class HelloNameRestlet extends Restlet
{
public void handle(Request request, Response response)
{
def data = [name:world]
response.entity = new
TemplateRepresentation('hello_name.txt.fm', new Configuration(), data,
MediaType.TEXT_PLAIN)
}
}
new Server(Protocol.HTTP, 3000, new HelloNameRestlet()).start()
Not sure if it matters, but I'm running my tests on an Intel Mac
running OS X 10.5.6 and all updates. I've duplicated this issue with
Java 1.5/32 and 1.6/64, and with Groovy 1.5.6 and 1.6.0.
I'm thinking this might be pointing to a minor bug somewhere, but I
couldn't begin to pinpoint where. I'm hoping someone else can!

Re: Managing a JPA/Hibernate session
Below is my solution which is based on a similar ServletFilter from the

this. I normall have that configured in spring and get a reference to this
filter bean from the context.

import org.restlet.data.Response;
import org.springframework.dao.DataAccessResourceFailureException;
import org.springframework.orm.jpa.EntityManagerFactoryUtils;
import org.springframework.orm.jpa.EntityManagerHolder;
import
org.springframework.transaction.support.TransactionSynchronizationManager;
public class OpenEntityManagerFilter extends Filter {
private static final Logger logger =
Logger.getLogger(OpenEntityManagerFilter.class);
private EntityManagerFactory entityManagerFactory;
protected int beforeHandle(Request request, Response response) {
if (TransactionSynchronizationManager.hasResource(entityManagerFactory))
{
request.getAttributes().put(this.toString(), Boolean.TRUE);
} else {
logger.debug(Opening JPA EntityManager in OpenEntityManagerFilter);
try {
EntityManager em = entityManagerFactory.createEntityManager();
TransactionSynchronizationManager.bindResource(entityManagerFactory,
new EntityManagerHolder(em));
} catch (PersistenceException ex) {
throw new DataAccessResourceFailureException(
Could not create JPA EntityManager, ex);
}
}
return super.beforeHandle(request, response);
}
protected void afterHandle(Request request, Response response) {
MapString, Object attributes = request.getAttributes();
if (attributes.get(this.toString()) != Boolean.TRUE) {
EntityManagerHolder emHolder =
(EntityManagerHolder)TransactionSynchronizationManager.unbindResource(entityManagerFactory);
logger.debug(Closing JPA EntityManager in OpenEntityManagerFilter);
EntityManagerFactoryUtils.closeEntityManager(emHolder.getEntityManager());

}

That works reasonably well, but unfortunately I haven't found a way to

}
public EntityManager getEntityManager() {
// we lazily initialize in case the entity manager is not actually
needed
// by a request
EntityManager entityManager = entityManagerTL.get();
if(entityManager ==
[Restlet] ?media= only available for registered types
I've been looking at the TunnerlFilter and have noticed that the ?media=mediaType query string extension only works if the media type is registered as a MetadataExtension with the the MetadataService. Is this by design?Or would it be possible if a metadata entry was not found to set the mediaType based on the value passed in?

The desire was to have something like errors error code999/code messagestart date is before end date/message /error /errors There was totally some desire to have the easiest and most verbose way to manage errors for the user as these 'restful' requests are going to have many many many optional params and some might conflict with eachother so the messages have to have some easy and quick visual rep to the user.

Plugable JAXBContext
Would it be possible to modify the JaxbRepresentation to support passing the a JAXB_CONTEXT_FACTORY property with the name of the factory to create the context. That class must have the following method. public static JAXBContext createContext(String, ClassLoader) throws JAXBException; This way you can easily plug-in say Jersey's JSONJAXContext to get Object-JSON mapping. Behind the scenes you would need to modify the getContext methods to maintain a separate cache for each context factory. Another alternate method would be to modify the class to have a static method to set the context factory to be used for a specific MIME type. With this approach when you use the MimeType, Object constructor it would use the appropriate JaxbContext factory for that mime type.

Re: Restlet vs other 'rest' frameworks questions/views
Matt, You can use JAX-RS on top of Restlet, so you get similar functionality as Jersey but with the benefit of being able to write a Restlet for any unusual cases. In terms of selecting different response formats you can use the accept HTTP header to allow users to specify the MIME type (e.g. text/ plain) and the Restlet or JAX-RS can do content negotiation. I think there is a way where the accept can be specified as a query string parameter for clients who can't set HTTP headers. I'd personally avoid using a wrapper, if there is an error return a HTTP error response. For the terms of use add that to a WADL document describing the resources and then just include the body direct in the response.

I.e. our first one. I am pushing hard for restlet but we also have some people who want to try jersey or even write some layer on top of spring mvc or look at struts 2... Here are my requirements. 1) All our responses will have some 'envelope' in terms of the response data. I.e. if we serve xml all responses would have a simliar format. e.g. company tos TERM OF SERVICE FOR ALL RESPONSES /tos error codes Here would be error codes like 'param not found' error codes response // concrete data here based on java object type /response /company I did this quite easily by creating a 'template' resources that handles a lot of the uniform plumbing (error catching, creating response object) and subclassed with concrete resources that would return the 'real data' via some template method. This worked lovely. I also used spring which was great as I could have state in my resources... Another desire is to parse the return type based on some uri param. i.e. //mywsite/cars/123 - return xml default //mywsite/cars/123?format=txt - return txt if supported by resource.. and NOT //mywsite/cars/123.xml Once again this shined with the great tunnel service.. I also used jibx on my domain models and once again used the Jibx Representation and it shined. The one down side my co-workers see is the lack of binding url params to some kind of bean element (like Struts, spring mvc etc) and that we would have to write our own. They are also curious about the 'scale' of restlet (if for example as a stand alone app) and the number of concurrent requests we can take at any given time. I will poke around at the code too see if i can dig up anything. Anyways.. This was a long rant but if anybody has some thoughts about how to convince my work to use RESTLET over others that would be great.
