Re: how to redirect to another resource?
Hello renfeng, did you try to call the following methods on the request object? - request.getResourceRef().getBaseRef() - request.getHostRef() - request.getRootRef() Otherwise, you can get the servletContext by casting the context: ServletContextAdapter c = (ServletContextAdapter) context; c.getServletContext(); But this method creates a strong coupling between your Restlet application and the Servlet container environment, and thus is not encouraged. best regards, Thierry Boileau I couldn't find a method to get the base url of ServerServlet. So it is hardcoded. Any clue how to retrieve it from the runtime environment? Thanks. String baseUrl = /context-root/restlet-root; router.attach(res1, new Redirector( getContext(), baseUrl + res2, Redirector.MODE_CLIENT_SEE_OTHER)); -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=989754

Re: how to Redirect...
Yes, i used redirectPermanent(...) to redirect to a resource. i tried to search for the difference between different redirect methods, can you please tell me how those 3 (permament, seeother,Temporary) are different. any resource URL also will be fine.

RE: How to redirect to a resource?
Hi Rob,
I've added the Reference constructor taking two refs as parameter (the
baseRef and the uriRef).
Concerning the redirection to relative URIs, we already have some logic in
place. See the current code:
public void setLocationRef(String locationUri) {
Reference baseRef = (getRequest().getResourceRef() != null) ?
getRequest()
.getResourceRef().getBaseRef()
: null;
setLocationRef(new Reference(baseRef, locationUri).getTargetRef());
}
I've made sure that this logic is invoked by the redirect*() methods taking
a String-based URI parameter.
Changes in SVN trunk. Thanks for the suggestions!
Best regards,
Jerome

Objet : Re: How to redirect to a resource?
I left out a step in the first example I typed. You have to
explicitly getTargetRef() ... I did this in the second block
of code but omitted it in the first. So, that example, corrected is:
response.redirectTemporary (
new Reference(
request.getResourceRef ().getParentRef().getParentRef(),
group/ + groupId
).getTargetRef()
);
your test case code would then be:
final String baseHref = http://localhost:8080/app/api;;
final String path = group/1;
final Reference ref = new Reference(new
Reference(baseHref), path) .getTargetRef();
System.out.println(ref);
... and that would yield the information you want.
For what you are doing, getRootRef() may be much easier than
trying to process relative references, which would require
you to know where you are in the hierarchy.
I still think it would be helpful if the Response redirect*
methods handled relative references more transparently ... it
is an extremely common use case to need to do this inside a
Resource, and I feel it shouldn't be necessary to master the
Reference API to do it correctly.
Cheers,

How to redirect to a resource?
Hi all,
I have a problem redirecting to a resource in my app if the app is
mapped to non-root URL. The setup is as follows:
I have a restlet application deployed in Tomcat under the /app
context. The restlet ServerServlet is mapped to /api/*, so to root
restlet of my application is actually mapped to
http://localhost:8080/app/api.
The restlets and resources are mapped as follows:
/item/{item} - ItemResource
/group/{group} - GroupResource (group is actually a collection of items)
/item{item}/group - ItemInGroupRedirectingRestlet
As the names may suggest, I want the ItemInGroupRedirectingRestlet to
redirect to the URI of a group where the item {item} belongs to.
However, if I call
response.redirectTemporary(/group/ + groupId);
it redirects to http://localhost:8080/group/groupId while I want it to
redirect to http://localhost:8080/app/api/group/groupId (as I have
written, http://localhost:8080/app/api is the root URL of my REST
application).
Can you please someone tell me what's the most appropriate way get it
redirected to the proper URL? Do I have to construct the target URL
manually by digging the necessary information from some Context
object, or is there a more elegant way?
thanks,
Pavel
Re: How to redirect to a resource?
Hi Pavel,
I'd start with the resource reference exposed by Request, and use the
methods of the Reference object to do what you want, e.g.
response.redirectTemporary(
new Reference(
request.getResourceRef().getParentRef().getParentRef(),
group/ + groupId
)
);
But Jerome and friends,
Now that I say it out loud, though, I can't think of a good reason why the
response.redirect* methods couldn't attempt this internally if they are
passed a relative URI string or reference, e.g. in o.r.d.Response:
public void setRedirectRef(Reference redirectRef){
if(redirectRef.isRelative()){ // relative redirects not legal in HTTP/1.1,
resolve
newRedirectRef = new Reference(
getRequest().getResourceRef(),
redirectRef.getFragment()
).getTargetRef();
// how come there isn't a Reference(Reference, Reference) constructor
anyway?
this.redirectRef = newRedirectRef;
} else {
this.redirectRef = redirectRef;
}
}
I would have to imagine this is *always* what the user would want when
passing a relative Reference or String into one of these redirects.
Thoughts, anybody?

Re: How to redirect to a resource?
Thank Rob, but the constructor Reference(Reference, String) does not seem to work, it actually produces a Reference instance that seem to completely ignore the first argument. More exactly, the following code: final String baseHref = http://localhost:8080/app/api;; final String path = group/1; final Reference ref = new Reference(new Reference(baseHref), path); System.out.println(ref); prints group/1 instead of http://localhost:8080/app/api/group/1;. However, I've realized I can get the URL of the root restlet by request.getRootRef(), so I'm able to construct the URL I need by simply calling request.getRootRef() + /group/1 thanks Pavel On 16/12/2007, Rob Heittman [EMAIL PROTECTED] wrote: Hi Pavel, I'd start with the resource reference exposed by Request, and use the methods of the Reference object to do what you want, e.g. response.redirectTemporary( new Reference( request.getResourceRef().getParentRef().getParentRef(), group/ + groupId )
