OAuth2: How to resolve "Unable to get the template authorize.html."
I am working through the oAuth2 sample code and have hit a Restlet issue that
has stymied me for a while. Following the sample code, I have:
HttpOAuthHelper.setAuthPageTemplate("authorize.html", getContext());
However, when AuthPageServerResource.getPage() is called the following code
is unable to find "authorize.html":
Configuration config = new Configuration();
ContextTemplateLoader ctl = new ContextTemplateLoader(getContext(),
"clap:///");
config.setTemplateLoader(ctl);
getLogger().fine("loading: " + authPage);
TemplateRepresentation result = new TemplateRepresentation(authPage,
config, MediaType.TEXT_HTML);
Specifically, result.template is null. The message that I see is:
WARNING: Unable to get the template authorize.html. Error message: Template
authorize.html not found.
The first problem I fixed was adding the CLAP protocol. My web.xml file
had:
org.restlet.clients
HTTP HTTPS CLAP
but that didn't seem to be enough, so in MyOauthServer.createInboundRoot()
method, I added:
this.getConnectorService().getClientProtocols().add(Protocol.CLAP); //
For Freemarker
this.getContext().getClientDispatcher().getProtocols().add(Protocol.CLAP);
// For Freemarker another attempt
This fixed the error message "FINE: The protocol used by this request is not
declared in the application's connector service. Please update the list of
client connectors used by your application and restart it." but did not
solve the null template problem.
It seems that the getPage() is trying to load a "class" of type "html" from
the top-level directory of my war file. And that is where I have
authorize.html. I also put it in the WEB-INF directory. In addition, since
MyOauthServer is setup in my web.xml file as:
AuthServer
org.restlet.ext.servlet.ServerServlet
org.restlet.application
com.fourspires.oauth.server.MyOauthServer
AuthServer
/oauth/*
I also put an authorize.html at "war"/oauth/authorize.html and
"war"/web-inf/oauth/authorize.html.
But alas, none of these work. Where do I have to place the authorize.html
file so that it can be loaded by the ContextTemplateLoader?
Note: I am running 2.2 GAE Edition.
Thanks so much!

RE: No buffer space available (maximum connections reached?)
Hi Arjohn, Thanks for reporting this issue, it should now be fixed in 2.1 RC5 and in the master branch. We now try to properly close the Pipe when an exception occurs and by default we now relay calls made on write(OutputStream) to write(WritableByteChannel) using a blocking channel, almost like you suggested.

Hi Thierry, FYI: We've tested this solution using a custom WritableRepresentation subclass for a couple of weeks now. We haven't seen this issue anymore since then.

Re: How to measure the performance of an app using Restlet 2.1
I already tried both JMeter and LoadUI and no output is shown i mean as for LoadUI there is no graph plotted its an empty graph thats why I am asking.. Although I have tried the tools on either URLs as google.com and it worked out. So my question is has anyone faced these errors or do anyone tried those tools and they were working normally with him/her ??

Yes both run under OSX IIRC. JMeter definitely, LoadUI probably.

Re: Restlet Framework 2.1 RC5 and 2.0.14 released
Hi Dalia, Please do not hijack the release thread. The problem you have with ab has nothing to do with Restlet, as I've already explained to you in an earlier post. Use an alternative load tool like LoadUI or Apache JMeter On 23 May 2012, at 23:21, Dalia Sobhy wrote: > Hiii Jerome, > > I have a problem with restlet 2.0.12, > > When I type this cmd $ab -n 10 -c 5 > http://localhost:8182/test/1235/retrievepatient > This is ApacheBench, Version 2.3 <$Revision: 655654 $> > Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ > Licensed to The Apache Software Foundation, http://www.apache.org/ > > Benchmarking localhost (be patient)...apr_poll: The timeout specified has > expired (70007) > > $ curl http://localhost:8182/test/1235/retrievepatient > info:address => > 6 Elfanan Ahmed Osman zizenia; info:bloodGroup => > O; info:dateOfBirth => > Sat Nov 10 00:00:00 EET 3860; info:fullname => > Nadia Badawi; info:gender => > male; info:maritalStatus => > MARRIED; > > So any info plzz because this is so critical to me, I want to test the > performance of my restlet web app... > > -- > View this message in context: > http://restlet-discuss.1400322.n2.nabble.com/Restlet-Framework-2-1-RC5-and-2-0-14-released-tp7574149p7574251.html > Sent from the Restlet Discuss mailing list archive at Nabble.com. > > -- > http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2964701 -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2964784
