Hi Dave,  saw your post and have been looking for similar facilities.  I want to consume (what would be along the lines of message enhancing) RESTful services (*not* built with RESTEasy, essentially just HTTP calls that return XML) from within my action pipeline.  I was looking for something *similar* to SOAPCLient, maybe called HTTPClient, but didn't find it.  What is the best practice for consuming RESTful services from an action pipeline, can you shed some light here?  Also, I'm curious about what happened to your HTTPRouter src, I don't really need a router but if there's nothing else perhaps I can make due.  Also, I saw posts talking about abstracting an HTTPClient and making it a parent of SOAPCLient, has anything happened on that?  Should I do it?  Sorry to pelt you with questions, I've been having a hard time finding ino on this... thx!

Hi, thanks a lot, I'll check that out and see.  So this code is an action of yours that interacts with the HTTP response to a jersey jax-rs client?  That sounds like something along the lines of what I need, I want to consume (not necessarily compliant) RESTful (or RESTlike) services from within an Action pipeline as a client and may well want to be able to route messages to RESTlike/ful endpoints too.  Anyway, I'm kind of a newbie to jboss esb, but I'll check this out, but I might have some questions if you don't mind, thanks.

Hi, Dave, so it looks like there is some stuff missing, processWADLDocRequest(), processWADLRequest(), processXSDRequest(), do I need this stuff?  Or should I chop out those branches of code and make them throw exceptions or something?  I'm not totally sure of your context as haven't done much work with JBossESB yet, but what I did was to tale your (I'm assuming this is for an Action class, right?) "process(Message msg)" method and slap it in another custom class, from simple_cbr quiclkstart.  So I'm guessing that the action that you chopped this out of does more stuff (like WADL stuff, or XSD stuff... true?) than make REST requests, so you only sent me part of it, is that right?  So, for ex., here:

if (requestInfo.getQueryParams().containsKey("doc"))
        return processWADLDocRequest(message, null);

Does it need to handle these cases?  I think there are 3 of them... or can I make them throw exceptions instead and I won't hit them?

THe other thing I wanted to ask you about was configuration of this.  I put the method fragment in one of the quickstart MyFooAction classes and renamed it WADLAction.java and slapped your process method in there (please fill me in about the missing methods above, I'm not at all familiar with Jersey).  I also put the JerseyClientSingleton class in the same package as the rest of the simple_cbr quickstart.  Do I need any configuration in jboss-esb.xml?  I think I see what your code is doing for the most part, now let's see if I can get it to work.  Thanks too, BTW!

Hi Dave, thanks for the info.  I'm trying to build the stuff now, but I'm getting an error on the HTTPClient:

[javac] /home/jack/java/jboss/jboss-soa-p.5.0.0/jboss-as/samples/quickstarts/simple_cbr/src/org/jboss/soa/esb/samples/quickstart/simplecbr/JerseyClientSingleton.java:9: package com.sun.jersey.client.apache does not exist
[javac] import com.sun.jersey.client.apache.ApacheHttpClient;

from this import in JerseyClientSingleton.java (line 9):

import com.sun.jersey.client.apache.ApacheHttpClient;

I took your advice (perhaps incorrectly) and put these 3 jars in my project lib folder but am still getting the compilation error:

asm-3.1.jar

jersey-bundle-1.3.jar

jsr311-api-1.1.jar

I put these in the lib directory of the project, which is the "simple_cbr" jboss quickstart which I'm using to test this stuff.  Am I missing a jar?  Or does it need to go in a different lib dir?  I was looking at this link for dependencies, I'm using ant (the quickstarts all use ant), so I'm following the instructions for non-maven developers:

https://jersey.dev.java.net/nonav/documentation/latest/user-guide.html#chapter_deps

Whoops, I looked through the zip file for jersey (I'm using 1.3, hope that's ok) and found the apache client jar and threw it in my project lib dir and now it built...  wooo!

OK, no need to respond here, I'm mostly posting this to help the next poor sap to come along

So the jars needed are:

asm-3.1.jar

jersey-bundle-1.3.jar

jsr311-api-1.1.jar

jersey-apache-client-1.3.jar

I'm sure I'll have more to say but thanks loads Dave, really appreciate your help!!

Hmm, some how I loaded stuff that wasn't properly compiled, I did an "ant clean" and found I don't have an import for "HttpResponse", do you have the import for that?  It doesn't seem to be in those jars, (I had assumed this to be Jersey stuff, is it?  Or maybe 3rd party?).  It's from this snippet of code:

HttpResponse httpResponse = new HttpResponse(response.getStatus());
httpResponse.setContentType(response.getType().toString());
message.getBody().add(entityResponse);
httpResponse.setResponse(message);

I also started looking at this code and it looks like it's processing an incoming request, is that true?  That's cool, but I don't want to do that at the moment., I just want to make an oiutgoing request and then probably enhance a message with the data.  Do I still use this same JerseyClientSingleton to create a brand new request I want to make from my WADLAction class?  Also, if you have a pointer to docs on this client that would be cool too, thanks.

[DIdn't see this] You had problems with Jersey 1.3 eh?  I can back off to 1.2, though, as long as they're still serving the download.

Hey, do you have the import for that HttpResponse class?  I found a class of the same name in an "spi" package for RESTEasy but it doesn't look right, it looks internal.  If you would fling me that package import for your WADLAction.java file for that I'd be muhjc obliged... thx

--j

[light goes on] This is all RESTEasy stuff?  Found several of the missing imports in resteasy packages, looks likely... pls conmfirm if you get a chance...

awesome, thanks, will sort it out, that makes it *much* easier
