RE: gwt compiler can

[Tomasz Kaczynski]

Hmm, 
the error was generated from my misguided attempt to use the FormDtaSet class 
in the client. The GWT compiler properly reported error and the .html package 
didn't provide to be inherited in GWT because it was meant for Server. The code 
in question runs on Server just fine.

RE: UriBuilder encoding

[Thomas Mortagne]

From what I understood this method is supposed to add a new segment and not
replace the {somevar}.

RE: Re: reg TokenBuffer

[Domnic]

Hello Thierry and Tim,
thanks you for your support. The example works like a gem. Yes Tim is right, 
When I include the Jackson 1.5 it is better. I am not getting this error.
thanks

AWS and Freemaker + Restlet

[Domnic]

Hi there,
I am trying to use a Freemaker template with a restlet Resource. this runs fine 
on local host i.e. on a standalone java. But when I try to export a WAR out of 
it.I get the following error while deployment.

Re: AWS and Freemaker + Restlet

[Tim Peierls]

The AbstractMethodError suggests that somehow you're getting a stub
ConverterHelper that doesn't implement the abstract score method. Make sure
you're using the Restlet J2EE edition and the servlet extension. Make sure
the Freemarker extension jar (and the Freemarker jar) are on your servlet's
classpath. (Make sure you're using the correct version of Freemarker for
the extension, too, but I don't think that's the problem.)

I wrote a blog entry about writing Restlet components that can be run both
standalone and as servlets. It's specifically geared to Elastic Beanstalk
deployments, and it depends on Guice heavily, but the ideas are applicable
in general.

RE: Re: AWS and Freemaker + Restlet

[Domnic]

Hello Tim,
Thanks for your reply. I have to learn Guice and follow up your code.. I will 
try that ASAP. meanwhile I tried the manual way... when I export a standalone 
restlet application into a war..and deploy in aws, it works.. but the moment I 
try to use the freemaker.. I get the errors. I rechecked the jars...and 
imported them in the WEB/lib folder and referenced it in the class path. Now I 
get a different error..

at 
org.restlet.engine.converter.ConverterUtils.getBestHelper(ConverterUtils.java:137)
at 
org.restlet.service.ConverterService.toRepresentation(ConverterService.java:208)

it is at the converterUtils. do you think it is still the jars.or I am missing 
something on my web.xml..?

thanks

Re: Re: AWS and Freemaker + Restlet

[Tim Peierls]

You could try instrumenting getBestHelper so that it dumps the concrete
type of the ConverterHelper, ch, just before it tries to call the score
method.

It certainly sounds as though the Restlet Engine is not finding the
Freemarker extension in the classpath, but I don't know why that might be
happening.
