Re: Tuscany class loading (was: Re: Using EMF with Tuscany 1.6)
On Tue, Nov 27, 2012 at 2:30 AM, Millies, Sebastian sebastian.mill...@softwareag.com wrote: Hello there, I've never been back to talk about this, so here goes. To re-iterate the problem: I want to set up my contributions, so that they can use different versions of third-party libraries than the Tuscany runtime. My original example was using recent versions of EMF (hence the subject line), another example is using Tuscany with an Apache Solr 4.0 backend, which requires different Apache Http Components. The standard recommendation is [1], but I have had great trouble to get that to work. (The reasons have to do with the use of SDOs in the application in question.) I have therefore decided to try the opposite approach of including any different versions of components used by Tuscany in nested jars in the contribution itself. Nested jars in a zip contributionget added into the contribution classpath. Here I am working under the assumption that the SCA contribution classloader would work somewhat like a webapp class loader in that it would not follow the delegation model, but would look for classes in the following order 1) inside the contribution 2) in the imports 3) in the parent classloader With this behavior, everything goes well. For example, I can make calls to Apache Solr through the solr-solrj-4.0.0.jar and its dependents, including httpclient-4.1.3.jar and httpcore-4.1.4.jar, without impacting HTTP calls made by Tuscany-generated proxies elsewhere. Here's the snag: As it turned out, org.apache.tuscany.sca.contribution.java.impl.ContributionClassLoader DID NOT work the way I expected, but rather looked in the parent classloader first, only then inside the contribution. I had to change the coding (in module contribution-java) and the associated test. A patch is attached. Would my change break anything, perhaps with respect to OSGi? Is there anything in the SCA spec that mandates a certain class loading behavior? I do feel that the alternative behavior is more natural than the one that is currently implemented. (There a very few resources on Tuscany classloading, and e. g. [2] does not seem to mention this particular issue.) Unfortunately, I cannot get all the Tuscany 1.6 tests to compile and run with maven. Please, would anyone be willing to see if Tuscany 1.6 with my patch applied would still pass all current tests?

It seems that you are posting a value to a REST resource, and receiving a

One possibility I considered was to make a new component that would have a reference to all components that implement the different API versions. But this routing component would itself need to have a generic interface that accepts all incoming requests. I'm not sure how to accomplish that.

In the HelloWorldJSONRPC example tuscany is started from the web.xml using a filter - does this serve the same purpose as the Launch.java class you have? Yes You also have some dojo included in you example but I don't see where it is used. Did I miss something? If so what? Some of the dojo details are hidden in the widget (see generated widget.js), but when i do personService.createPerson(person).addCallback... that's basically invoking a remote service via json-rpc using dojo. The sample in the distribution is very close to what I need - starting Tuscany form web.xml and not using dojo. I just need it to send objects to back end. Good luck, you should be able to identify the things your application needs from the sample I provided.

But it looks like the custom header values are not returned by the rest binding classes and there's no way right now to add a custom JAX-RS provider to parse the response. Is my understanding correct? The REST binding currently does not allow you to inject your own providers. The existing binding.rest does add two custom JAX_RS providers - DataBindingJAXRSReader and DataBindingJAXRSWriter - which hookups the Tuscany runtime's data binding framework and allows them to read and transform the request and response bodies, but there's no explicit support for parsing custom headers, right? Thanks Anuj One of the benefits of using Tuscany/SCA is the ability to abstract the actual infrastructure layer being used which allows your service to be exposed with different bindings. Based on that, having your service interface dependent directly on http specific things will make it less flexible. Having said that, if this is really a requirement, you could try using some of the JAX-RS/WINK specific resources into your service like @Context private HttpHeaders headers; or try using wink extensibility... -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/

Is there any chance of upgrading this to Apache HttpComponents HttpClient (currently 4.1.1)? Is it really necessary to have the dependency in Tuscany at all? Best, Sebastian Hi Sebastian, This dependency is necessary because HttpClient is used by the Java code in a number of Tuscany modules: binding-atom-abdera binding-feed binding-gdata-runtime binding-jsonp-runtime binding-ws-axis2 To upgrade this dependency, the pom.xml files in these modules would need to be changed to use the newer version, and the newer version would need to be verified for compatibility by doing a complete top-level build. The commons-httpclient dependency also appears in the following poms: modules/binding-rss-rome samples/simple-bigbank-spring There's no use of httpclient in the Java code for these modules, so it should be OK to remove the dependency from these poms. The 3.1 level of commons-httpclient is used by Axis2 1.4.1. It would be necessary to add explicit exclusions for this in all the Tuscany poms that have an Axis2 1.4.1 dependency, and add the newer version to these poms as an explicit dependency. It would also be necessary to verify that Axis2 1.4.1 works correctly with the newer version. This could be quite a lot of work. The binary distribution build would need to be changed to exclude the commons-httpclient-3.1 jar file (brought in as a dependency of Axis2) and add the newer HttpClient jar instead. Then the binary distribution would need to be tested fully to make sure that it still works correctly. Finally the LICENSE file in the distribution module would need to be updated. I think that's everything, but I might have missed something. Would you like to try doing this, and then create a JIRA with a patch so that someone can apply it? Simon We moved some of these HttpClient 3.1 dependencies to a more current release in 2.x and while doing that we noticed that the two APIs are incompatible, so changing in 1.x would require some code changes. I believe we can do that in all our bindings, but we need to investigate what are the side effects/hard dependency on this library. -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/

My question regards the difference between composite and default (request) scope, disregarding conversations. As I see it, either a service implementation maintains state or it does not. If it does, it must be made composite scope, so as not to lose the state between requests, and one must take care of shared access (thread issues) in one's programming. If it does not, it wouldn't matter if it were composite scope, as there would be no shared state to care about how to access anyway. So it could as well be made composite. A service being composite scope earns the additional benefit of the init() method, which can be costly, only being executed once. So I would decide to make all my services composite scope by default. Would that be wrong? In other words, is there any particular advantage associated with default scope services?

Tuscany related sessions at JavaOne 2010
Some of us will be at JavaOne this year, and we will be presenting two Tuscany related sessions : Session ID: S314011 Session Title: Developing composite applications for the Cloud using Apache Tuscany Wednesday, September 22, 11:30AM Today's cloud environments pose new challenges for application developers: hiding cloud infrastructure from business logic, assembling components on heterogeneous and distributed cloud environments, and optimizing the provisioning of the required cloud resources. This session will demonstrate how to use Apache Tuscany and the Service Component Architecture (SCA) to develop, build, and run an application composed of several service components in a distributed cloud environment. We'll illustrate how to encapsulate cloud infrastructure services as SCA components to simplify the construction and assembly of the application and how to move components around and rewire the application to adjust to new business and cloud deployment conditions. Session ID: S313731 Session Title: Databinding Unleashed for Composite Applications Tuesday, September 21, 8:00AM Data bindings such as JAXB, SDO, DOM, and JSON denote how business data is represented. Collaborating components in a composite application often need to use different data bindings as required by the business logic or protocol stacks. Apache Tuscany provides a framework that allows mixing and matching of data bindings so that application developers can have the freedom to choose their preferred data binding technology without worrying about complex data transformations. This session is for developers looking for flexibility of data bindings in the enterprise. Attendees will learn about: * Decoupling data bindings between service consumers and providers * Tuscany?s approach to transform data without the intervention from application code If you are going to be around, stop by and introduce yourself... -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/

Re: Tuscany 1.6 vs. 2.0
On Thu, Sep 2, 2010 at 3:39 PM, Millies, Sebastian sebastian.mill...@ids-scheer.com wrote: I am not sure about moving up to Tuscany 2.0. Can anyone comment on the state of the 2.0 code to help me decide? You should definitely move to 2.x, and in the case that you might be using some extensions not yet migrated to 2.x let us know, or let us migrate it. A few things come to mind: Have the specifications on which 2.0 is based even been finalized by OASIS? How stable is the code? There are many bugs in JIRA for 2.0, but much fewer for 1.6 - is it because 2.0 is in a state of flux, or because no one bothers with 1.6 anyway? 2.x has been in more active development, and we are also tracking compliance fixes/todos via jira, that's probably why. What about the sad lack of documentation for 2.0? A lot of 1.x documentation still applies to 2.x. We have also started a wiki to migrate 2.x specific documentation at http://tuscany.apache.org/documentation-2x/ The very fine book Tuscany SCA in Action is based on 1.4 - how much of that will survive for 2.0? How much work would it be to migrate to 2.0 later on? What constructs should be avoided now to make such migration easier (conversational interfaces etc.)? A lot of the concepts haven't changed, samples might change a little, but people have started porting the Travel Sample to 2.x as well, which is the sample used in the book. When developing a business application, with a team that does not have much SCA experience, at the moment I'd feel slightly safer with 1.6. Do you think I should overcome that feeling? Yes, and if you find issues, you will definitely get a quicker fix if this is in the 2.x code stream. Well, these are my personal view.. others feel free to jump with your thoughts. -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/

Re: SCA/Tuscany x Portlet JSR 268
Ola Paulo, comments inline On Mon, Jul 5, 2010 at 12:17 PM, Paulo Alvim al...@powerlogic.com.br wrote: Hi Folks, I`m starting with SCA/Tuscany and I have a few conceptual questions: I need to build some kind of “Dashboard/Portal” application composed by a “Dashboard View” (a dynamic layout) and various dynamic Dashboard Gadgets that I’d like to develop in a component model like SCA. In fact, I could use “Portlet JSR 268” but I would need a traditional “server centric” Portal product – and my impression is that the portlet model is old fashioned (although I’m not completely sure). I’d like to have only one SCA (Java) component that should be able to: - FIRST: Serve “Web Static Content” (HTML5, CSS3 and Javascript files) to be rendered in a dashboard panel/gadget area (this would probably be persisted locally by using HTML5 Local Persistence) - SECOND: To keep RESTful Ajax interations with the client My questions are: 1. I didn't find examples of SCA components serving client content (HTML) directly. The HTML/CSS/JS files are normally deployed in the client application. But it’s a reasonable architecture? Is there any problems to do that that I can't see (as a begginer)? Here is an example of a service returning images, should be same scenario as the one you are describing, where you want to basically send resources back to client. http://svn.apache.org/repos/asf/incubator/photark/trunk/photark-jcr/src/main/java/org/apache/photark/jcr/services/JCRImageCollectionImpl.java !-- Component responsible for providing REST access to images -- component name=ImageServiceComponent implementation.java class=org.apache.photark.jcr.services.JCRImageCollectionImpl/ service name=ImageCollection tuscany:binding.http uri=/gallery/ /service reference name=repositoryManager target=RepositoryManager/ /component You also mentioned you want to have a AJAX iterations between the client and the services, and you could also see an example of a in-progress REST API at http://svn.apache.org/repos/asf/incubator/photark/branches/photark-rest/ Some other examples are available in the binding-rest-runtime test scenarios https://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/modules/binding-rest-runtime/ 2. If it's reasonable: Must I deliver this component as a regular JAR or is there another more appropriate format in SCA/Tuscany? In SCA, you are delivering things as contributions, depending on how you are packing your application you can have jars, zips or even folder structures as contributions. 3. Does anyone have links (or arguments) about “portlet JSR268 x SCA”? I don't think these two technologies compete with themselves. SCA would be used for assembling you services, where you would use JSR268 more towards providing portlets (ui pieces/widgets) that consume your SCA services. Having said that, I'm not sure if you are asking more towards replacing JSR268 with SCA, and if that is your question, let me put this way, you should be able to build your ui that integrates with your SCA Services as Portlets, JSPs following Java EE standards, Web 2.0 client applications (you might get some help of SCA Widgets), etc Thanks in advance!

I'd tried that too, but that was hours ago now and nothing seems to
have changed so i don't think its working.
Whats interesting is if you look at the html page source the text is
there but wrapped in what must be incorrect tags, for example the
bottom of the page
http://tuscany.apache.org/sca-java-implementationjava.html has:
DIV class=code panel style=border-width: 1px;DIV
class=codeContent panelContent
SCRIPT type=syntaxhighlighter class=toolbar: false; theme:
default; brush: java; gutter: false![CDATA[

name=SampleCompositegt;
lt;component name=SampleComponentgt;
lt;implementation.java class=sample.SampleImpl/gt;
lt;/componentgt;
lt;/compositegt;
]]/SCRIPT
/DIV/DIV
...ant
There is a thread going on around the {code} tags in the infra@ list,
this seems to be related... there are some people reporting things are
related to rsync from some internal machines ... so this is not a
specific case in Tuscany, but a more broad infra issue...

Hi,
I thought that my problems are over, but unfortunately I still have a
problem to connect client web page with tuscany web server. I did everything
as you suggested but I firebug gives an error 404 method not found message.
This is code integrated in web page:
$(document).ready(function(){
$.getJSON(http://ZoranPC:8080/CreateLearningGoalsService/getServiceTest;);
});
If you are trying to overcome the javscript domain limitation, you
need to use JSONP more like the following :
function getGreeting() {
var name = document.getElementById(name).value;
$.getJSON('http://localhost:8081/HelloWorldService/sayHello?name='
+ name + 'callback=?', handleResponse);
}
function handleResponse(data) {
document.getElementById('greeting').innerHTML=data;
}
This is the content of the composite file:

Please take a look at the example I ported to 2.x as it seems you are
till trying to configure your service trough promotion, this is what
is causing your service endpoint not to be available... and you are
STILL using JSON-RPC instead of JSONP binding
CreateLearningGoalsService class defines two methods:
@Callback
String getAvailableCompetences(String sortingCriteria);
void getServiceTest();
What are you trying here with the CallBack ?

There are two things here :
1) You need to adjust the SCA related artifacts (e.g composite,
sca-contributions.xml, etc) to the proper namespace... this seems
right as of now
2) You need to have the proper 2.0 dependencies that will register
processors to handle these artifacts, and this seems to be your
problem
Could you please make sure you are using 2.x or 2.x-SNAPSHOT
dependencies to the updated project

Hi,
Does it matter how your JavaScript communicates with the server
- does it just need to make request-response style calls to the server
so the protocols can be handled and hidden by Tuscany, or do you need
control over that, for example to use jsonp or jsonrpc or a particular
toolkit like Dojo or JQuery?
I'm not sure in the moment if I will have some specific requests regarding
the protocols. I think not, but I need to exchange json like data (used to
generate jsTree component) between server and client.
I have already tried to use Dojo, as it looks like nice solution to my
problem, but I couldn't make it works. I used provided examples, but I don't
know if I have missed something. Here is a code:
script type=text/javascript
var djConfig = {
parseOnLoad: true,
baseRelativePath: dojo,
isDebug: true,
debugContainerId: dojoDebug
};
djConfig.usePlainJson=true ;
/script
script type=text/javascript src=js/dojo/dojo.js/script
script type=text/javascript
dojo.require(dojo.parser);
dojo.require(dojo.rpc.JsonService);
/script
...
var smd=new
dojo.rpc.JsonService(http://ZoranPC:8080/CreateLearningGoalsService?smd;);
var
competences=smd.getAvailableCompetences().addCallback(contentCallBack);
I always get error in Firebug
smd.getAvailableCompetences is not a function.
Did I miss something here. I didn't add anything Dojo related to the server.
Do I need to use something there in other to connect client with Web
Services.
Zoran, overall, your application looks ok, and after a slight
modification to make the services available from the same webapp [1] i
could retrieve the available competences from the backend service with
the following code :
dojo.addOnLoad(function() {
dojo.require(dojo.parser);
dojo.require(dojo.rpc.JsonService);
var smd=new
dojo.rpc.JsonService(http://localhost:8080/sample-intelleo-lpc-webapp/CreateLearningGoalsService?smd;);
var
competences=smd.getAvailableCompetences().addCallback(contentCallBack);
});
Note that i have to access the application trough
(http://localhost:8080/sample-intelleo-lpc-webapp/lpc/index.html) to
get the javaScript included via relative paths to work.
Have said that, you need to think on how you want to partition your
application, as having your service being provided from a given
host:port and trying to access it via a JavaScript served from a
different host:port will hit JavaScript security constrains (see [2])
and you will need to use some type of proxy, component proxy (e.g a
local json-rpc component that references a remote json-rpc service),
jsonp or some other technique. Note that this is not a particular
limitation from Tuscany or SCA, but something related to how
JavaScript and Browser security works.
I hope this helps and let you make progress, don't hesitate to ask
further questions.

As I understood this, there is no way to have a javascript outside of the Web service application? My idea was to extend some of the existing Web application like Elgg, Wiki etc., with additional Learning Web services accessible through a popup containers developed with javascript and jQuery. This javascript client should communicate with Web services to get its functionality. It is possible to let javascript client be part of the same application where Web services are stored, and include it in Elgg with absolute path to remote javascript file, or to make it be on the same server where Elgg is stored and then access Web services from javascript through absolute url. I hope you understand my idea, so I would like to hear your comment and idea what would be the best possible approach to make all these thinks work together. Do I have to put all three parts (Web services, javascript client and Elgg) in the same application?

These services, by and large, can be (and should be) totally stateless and thus, in the interest of lower GC issues, singletons. Great, we @Scope them as Composites. Well, maybe this is a bug in Tuscany and we should implement support for stateless more efficient (e.g by providing a pool of instances). Could you please fire a jira and mention the release you are using. As you mentioned, @Scope(Composite) could be a possible workaround for now. However, if we want to have an asynchronous 'conversation' with these... well.. we haven't figured out how to do it. Issues: 1. The callback functionality is injected into the destination component object rather than maintained by a proxy. If this object is a singleton-ish entity.. well, not thread safe. 2. When the callback is actually made, the originating caller (that might be scoped as 'Conversation') can't be located and a new instance is created. This may be because the singleton's callback is being corrupted (overwritten).. thus just another variant of issue 1. So is it possible to scope a component as a 'Composite' and yet enable 'Stateless' or 'Conversation' scoped components interact with them in any asynchronous way? In this case, it seems that we are actually making the stateless service statefull, by injecting callBack information. How about trying something like passing the current object in the business operation (e.g foo(this, par1, parm2)) ?

Not 100% sure here but I'm assuming the client side still needs the smd description in order to understand the jsonrpc version of the service interface. You can try adding ?smd to the end of the service URL that is registered with the webapp container. Assuming this is available do you see this being pulled by the browser?

I fixed a similar problem with tuscany is not defined by changing the script inclusion for store.js to /sample-webapp-store/store.js in store.html, and the current committed store.html has dojo.js included in a similar path (attempting to fix this by symmetry with the previous fix), but alas I don't seem to be able to include the dojo.js script. I've been blundering around in a browser trying to guess where dojo.js might be found, but as yet no joy. Can anyone help me pin this down please? In your scenario, where the application does not provide the dojo resources we are going to use the ones from within the web-javascript-dojo module and there was an issue on how we were trying to serve dojo resources from DojoResourceServlet (basically not considering contextRoot when in a web application server). Having said that, I would like to remove your changes from revision #916355, and fix the runtime to allow this to work in both embedded and hosted environment more transparently. Note that after my changes, there is still one issue, which seems to be related to host-webapp changing the contextPath and that seems to make the tuscany widget miss behave as it was trying to reach the initial registered endpoint based on the binding-uri... hope this gets you going... and I can check this further tomorrow... -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/

The war is built with maven in distribution/tomcat You could also try mvn -Pdistribution clean install The other reason why we're not moving to 2.0 is because the Eclipse SCA tools aren't yet complete.

When will DomainManagerLauncherBootstrap be ported over to 2.x from 1.x? I’m doing a study on Tuscany. My boss prefers the version that follows the OASIS spec. But since 2.x is unstable we might have to go with 1.x for now. Tuscany 2.x releases are being called Milestones because they are based on the OASIS 1.1 specification drafts. We have plans to release the official 2.0 right after the OASIS 1.1 specification is officially released. Rather then trying to specifically talk about DomainManagerLauncherBootstrap, I'd like to learn more about the scenario you want supported, as we are enhancing our Domain/Node story in 2.x. -- Luciano Resende http://people.apache.org/~lresende http://lresende.blogspot.com/
