[GSoC-2011] Final Evaluations Passed - Appreciation
Hi devs, I am happy to inform you that I have successfully passed GSoC final evaluations. I think this is a right time for me to thank all who helped me in my journey as a newbie in Tuscany. First of all I (again) like to thank Jean-Sebastien, my mentor, who helped me through out the project with his valuable ideas, more importantly I appreciate the freedom given and guidance provided by him. Your trust on me and the encouraging words helped me a lot in successfully finishing the project. Secondly I like to thank Raymond Feng who helped me mostly in the application period by reviewing my proposal and providing me his feedback. I strongly believe your comments helped me to pull up a compelling proposal. Ant Elder, helped me enormously through his ideas. Thank you Ant, I highly appreciate the support extended by you. Luciano Resende, Simon Laws, Mike Edwards, Florian Moga and Simon Nash also helped me by replying to my emails in the mailing list, thank you! I sincerely hope all of you find Tuscany Composite Diagram Generator useful! :) Finally, I had an awesome time throughout the summer with Tuscany, and I am hoping to contribute to Tuscany in future as well!

I have added the HTML wrapper ( https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/CompositeDiagramGeneratorUsingBatik/src/main/java/org/apache/tuscany/sca/impl/html/HTMLWrapper.java ). I used Canvg (http://code.google.com/p/canvg/) which was released under MIT license (compatible with Apache 2 license: http://www.apache.org/legal/resolved.html#category-a) and I included the two Java Script files of Canvg + the MIT license file under resources directory ( https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/CompositeDiagramGeneratorUsingBatik/resources/ ). I think there is a procedure when including source from another license, which I am not familiar with! I avoided using Canvg since, it is not needed. I modified the HTMLWrapper code ( https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/CompositeDiagramGeneratorUsingBatik/src/main/java/org/apache/tuscany/sca/impl/html/HTMLWrapper.java), now it's simply embedding the svg document, inside a HTML. - Use groups (svg:g) to nest the various shapes you're generating. This should help simplify your code as you won't have to worry about positioning related shapes (as they'll be naturally nested). I'm not sure whether this is necessary, since the dimensions of artifacts changes dynamically (i.e. according to their quantity), I should position each artifact dynamically. You have different thoughts? - To help navigate nested composites and included composites, generate links to their diagrams (perhaps you've already done that but I couldn't see it with the example diagrams you've committed). Ya, I've already done that, please see MyValueComposite2_diagram.svg from your web browser. - Position the titles below or above the services and references. Right now they're kind of mixed with the services / references. It was in displayed in the center of the services/references. I added them to top of each service/reference! These are only suggestions. Think about about them and decide yourself if you think they're good ideas or not.

It looks like its putting them at the top whereas the spec images have them centered. Having them centered looks better to me, what do you think? Done! Indeed

Hi Ant, On Mon, Aug 8, 2011 at 1:58 PM, ant elder ant.el...@gmail.com wrote: Nirmal, I've just committed a module with a couple of classes that show how your SVG code could be used by the Tuscany Shell to draw SVG pictures of composites: https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/CompositeDiagramShellPlugin/ The code is pretty simple, just one Batik class copied from their examples to display an SVG with Swing, and one small class for the Tuscany Shell command. If you check that out and from its directory do mvn tuscany:run it will start the Tuscany Shell and you'll see in the help there is a new draw command, and entering draw CompositeDiagramShellPlugin helloworld.composite it will try to display the SVG. That doesn't quite work as the EntityBuilder has a problem parsing the XML. Ideally it wouldn't have to parse the XML but would be able to work with the Tuscany Composite object directly. Thanks for the contribution ! :) What do you think about adding another EntityBuilder impl that works with the Composite object? I added the support to the Tuscany composite object by adding TuscanyCompositeEntityBuilder class: https://svn.apache.org/repos/asf/tuscany/collaboration/GSoC-2011-Nirmal/CompositeDiagramGeneratorUsingBatik/src/main/java/org/apache/tuscany/sca/impl/layout/TuscanyCompositeEntityBuilder.java And tried to run the shell command, but I think there's some problem with the temp file which you are creating in DrawShellCommand class. ...ant On Sat, Jun 25, 2011 at 1:54 PM, Nirmal Fernando nirmal070...@apache.org wrote: Hi All, I need your help to decide how should Composite Diagram Generator loads composite XML.

Maybe, but I'm not sure, as the runtime is not supposed to proceed with incorrect composites. Last time I checked, but that was about a year ago, I was getting exceptions preventing me to proceed and get the composite model. The error handling may have been improved since then. Better check with the other Tuscany folks working on that. (assuming that the validation part is done separately) I'd recommend to double check without assuming :) I will! With the code i showed earlier it would throw exceptions when there are problems with contributions or composites so thats not going to fit in well with trying to use buggy, unresolved, or incomplete artifacts. It is possible to pass in a Monitor object on some of the calls which prevents the exception throwing and instead the problem information is collected in the monitor which you can then examine afterwards to find out about the problems so you probably could get something working using that approach, but I don't really know how well it would work as we don't presently have much in Tuscany trying to do that type of thing. It seems a little ambitious IMHO, if it were me I'd probably want to at least first get something working with artifacts without problems, eg take the contribution from the helloworld sample and draw a picture of its composite - can the SVG generation code you have do that yet? Considering all the facts (such as getting exceptions when we load a composite with errors etc.) I decided to stick with my own code on to recognize artifacts in a composite XML :), but of course I could get help from existing code.

Re: [Composite Diagram Generator] Need a suggestion
Firstly many thanks to Luciano, Ant and Jean for your valuable ideas.

I think this calls for bigger questions: - Why will a user want to use the tool? - How will he use it? Here are some ideas, as I can think of a few use cases: A) I'm an SCA app developer and I want to use it to visualize the composites I'm in the middle of authoring on in my development environment. B) I'm an SCA app developer and I want to use it to browse a bunch of composites that I'm thinking about reusing. C) I'm a system administrator and I want to use it to browse the domain composite, the composites it includes and the composites it uses to check that my domain is correctly configured and wired up. D) I'm embedding Tuscany, building some tools for it, and want to generate these SVG diagrams programmatically. With these use cases in mind, I can see the following requirements: t) a command line tool that takes the text of a composite on standard input and prints the corresponding HTML + SVG on standard output; Do you mind explaining what you meant by corresponding HTML output? u) a command line tool that takes a directory containing a bunch of SCA contributions, and produces a tree of HTML + SVG linked together; v) a Web based tool that takes the URL of a composite document and serves the corresponding HTML + SVG; w) a Web based tool that takes the URL of an SCA domain and serves the corresponding HTML + SVG documents; x) a reusable library that takes the text of a composite and returns the corresponding SVG for it; y) a reusable library that takes a list of SCA contributions URLs and produces a tree of HTML + SVG linked together. z) all of the above should work with buggy, unresolved, and incomplete composites or they won't be really useful to a developer or administrator... just think of a Java editor that couldn't load a Java source with bugs in it... it wouldn't be so useful :) So, I think still I can use Tuscany runtime to load the composite XML, am I right? (assuming that the validation part is done separately) Obviously you don't want to implement all of the above right now... To start small and simple, you could just do (x), (t) and (z), which would already be great! Then you could try to do (v) (x wrapped in a servlet) if you have time, for a nice Web browser based experience... Hope this helps Thanks -- Jean-Sebastien -- Best Regards, Nirmal C.S.Nirmal J.

Currently the tool runs independently. It gets the composite XML as the input and outputs the composite diagram. To load the composite diagram Ant suggested me to use Tuscany which makes implementation easier. So the issue I have is whether to load the composite XML using jar file is better than directly loading composite XML (By the way, is this possible with Tuscany?). Highly appreciate your ideas! If this is part of a Domain Manager kind of thing, you could have some options like : a) display the diagram from the domain composite, this would display the aggregate view of all contributions, components, etc available on the domain b) from the information harvested from the domain, you could list the contributions, and it's deployable composites, and the user can click on it, to display the diagram for that specific composite. I had started doing some of harvesting of the domain composite and list of components, etc on nodeManager module in trunk Thanks! -- Luciano Resende http://people.apache.org/~lresende http://twitter.com/lresende1975 http://lresende.blogspot.com/
Possible ways to specify target service for a reference
Hi All, As you know, I'm in the process of creating composite diagram automatically for a given composite XML. I have a question, where I need your input.

Which one will be more successful? Reusing is good other than building one from scratch not knowing what will be the outcome, don't you think? Sorry for the delay, I've been really busy recently. In a way it's good that I didn't reply too quickly as that allowed you to figure part of the answer yourself :) and I see that you've given up on Graphviz after running into some limitations. No problem! :) I think my main observation is reusing software requires to evaluate: a) the useful function provided by that software that'll help you; b) its baggage, limitations, bugs, operational constraints that'll get in your way; c) the effort to understand how to use it to your advantage; d) the effort to adapt and glue it to the pile of other software you've decided to reuse. ... and put that in balance with: e) not reusing that useful function; f) but spend the effort you'd had spent to (b), (c) and (d) on writing the exact function you need. Often people only look at (a) and then struggle with (b), (c), (d). I think this is a problem in particular on the Java platform, where the development community is very quick to reuse giant piles of code just because they're available, without measuring all the implications (as opposed to C or C++ where developers tend to think more before making a move, or Python for example where libraries are typically smaller or much easier to re-implement). Thanks for the explanation! I looked at the code you've started to commit in the collaboration area. Looks like a good start to (f) -- spend quality time to implement the algorithm you need :). I started on layout algorithm and send a progress diagram to the dev list, hope you saw it! I have a few review comments: - it's good that you have Apache license headers in some files, would be even better to have them in all the files; Just now committed! :) - a few more comments in the code will help others in the community review and understand your code, and perhaps even come and help you; Added few, but will add more in coming days! - a Maven build and automated JUnit test cases will help you and others exercise your code and verify that it works.

Which forms of reference specification are you dealing with at the moment? The basic ones are: o @target parameter o @autowire o promotion (and thus targeting at a higher level) o wire/ element(s) o binding with a specified target URI Currently only @target attribute is supported. I wanted to know what other forms are exactly needed! In the spec there are 7. 1.Through a value specified in the @target attribute of the reference element 2.Through a target URI specified in the @uri attribute of a binding element which is a child of the reference element 3.Through the setting of one or more values for binding-specific attributes and/or child elements of a binding element that is a child of the reference element 4.Through the specification of @autowire=true for the reference (or through inheritance of that value from the component or composite containing the reference) 5.Through the specification of @wiredByImpl=true for the reference 6.Through the promotion of a component reference by a composite reference of the composite containing the component (the target service is then identified by the configuration of the composite reference) 7.Through the presence of a wire/ element which has the reference specified in its @source attribute. - I leave out @wiredByImpl since there is no implementation type that does this at the moment Yours, Mike. -- Best Regards, Nirmal I would list, in decreasing priority order: - @target - wire - promotion Great! I'll provide support for the above 3. Thanks. - autowire, which you could leave out for now, as (1) I've not seen it used a lot and (2) if you didn't want to explicitly declare the wires explicitly, but on the other hand you really want to see them in a diagram... I could argue that you don't really know what you want :) - binding URIs, I'd leave that one out as configuring binding endpoint addresses is not really wiring.

If Graphviz implementation succeed, I am not sure whether it is worth to put an effort on 'nothing' approach. What do you think? Thanks. I think the best way to know is to try. I didn't mean spending a lot of time investigating the 'nothing' approach. Just enough to decide if it's worth doing, or if it can be eliminated without a doubt... but based on concrete data. I think there's different aspects in what you're trying to do: a) walk an SCDL model and transforming it to a model from which you can derive a layout easily b) compute the layout of the composite diagram c) generate SVG for that layout d) allow a user to navigate it, zoom etc My guess is that Graphviz and Batik won't help with (a), may help with (b), are probably over complicated for (c), and I don't know if they can help or instead get in the way for (d). I am experimenting with graphViz and it appears to be used for our tool. Will update you soon, about my conclusions on using graphViz. The 'nothing' approach wouldn't change the situation for (a), would require you to think hard and craft some algorithms for (b), and wouldn't get in your way for (c) and (d). True, depending on how graphViz reacts this approach will be considered. Another way to ask the question is: What if you spend time to master Graphviz (1.6Mb) and Batik (1657 classes, 8Mb) and build something nice with them, and then somebody else just tries without these big dependencies, at the expense of some hard (but interesting) work to craft and tune the necessary algorithms, and produces a similar result with a few pages of lightweight code?

I already did this. :) I don't recommend you try and build the whole distribution as it literally takes hours with an empty maven repo (you probably noticed Tuscany integrates a good number of different technologies). It's enough to build the modules you're making modifications on to reflect them into the runtime. The rest of artifacts will be downloaded from the apache-snapshots repository. There are times when the Hudson nightly build fails and 2.0-SNAPSHOT artifacts don't get deployed to the apache-snapshots repository so if you need them, you'll need to build them yourself.

It supports multiple layout algorithms and the .dot file is a very simple text file that describes the graph (vertex, edge). The Graphviz tool can export the .dot into most of the image formats.

Composite XML should be generated using the Tuscany's in-memory representation of the composite model. It will then will give as an input for the Composite Analyzer. Composite Analyzer then analyzes the XML document and grab the relevant DOM Elements such as Composite, Component, Service, Reference, Wire etc. and starts to build the SVG document using SVG DOM API of Apache Batik.

Hi All, I'm an undergraduate at Department of Computer Science and Engineering, University of Moratuwa, Sri Lanka, and I'm hoping to have an exciting summer with GSoC 2011. I participated in GSoC 2010 for Apache Derby (RDBMS in Java) project and successfully finished the project. This is a sample of the work (final output) which I've done for Derby last summer (http://nirmalfdo.blogspot.com/p/my-work-at-gsoc-2010.html). You can find my profile and recommendations at LinkedIn (http://www.linkedin.com/profile/view?id=54105394trk=tab_pro). While looking through The ASF idea page, I found this entry in JIRA about Develop a simple tool that can be used to generate composite diagrams from the xml files https://issues.apache.org/jira/browse/TUSCANY-3496 is interesting. I would appreciate if I can get further details on the requirements of this tool. I'm still new to Apache Tuscany project, but willing to learn quickly, any help on getting me started is highly appreciate. Thanks. -- Best Regards, Nirmal C.S.Nirmal J.

The idea is to have a simple way to generate a diagram from the composite file to illustrate the SCA components (service/reference) and their wirings. It could be a simple .dot or .svg file. Eclipse has a tooling project for SCA [1]. It can generate nice diagrams. This idea is more on the lightweight side, for example, allowing a browser to point to Tuscany runtime to show the composite diagram. [1] http://www.eclipse.org/stp/sca/ Thanks for the quick response Raymond, I will study on Apache Batik Project http://xmlgraphics.apache.org/batik/ and Eclipse tool and will log my findings on JIRA. If you have any other thing in your mind that I should start looking at, please share them. I am hoping to contribute to this project in GSoC! Thanks.

Just a thought: if you're going to generate SVG using Batik, it'd be really cool to be able to edit the diagram too. It shouldn't be too difficult to add mouse onclick event handlers to the SVG elements representing components, wires etc and let the user move them around, unwire and rewire components for example. This sounds interesting Jean, thanks for firing it up! Another thought, since Raymond mentioned Eclipse tools. It may be worth taking a look at Eclipse Orion [1][2] and see if you can use any of it... I mean, if it's not too complicated and you think that it'll actually help you with the user interface. [1] http://www.eclipse.org/orion/ [2] http://download.eclipse.org/e4/orion/ Orion looks pretty cool! I will consider the possibility of using it in this project. Thanks Jean for the support, hope you'll continue! Thanks! -- Jean-Sebastien -- Best Regards, Nirmal C.S.Nirmal J.

Invalid links in sca-java-development-guide
Hi All, While surfing through Tuscany web site's sca-java development guide, http://tuscany.apache.org/sca-java-development-guide.html I've noticed that some links to repositories are broken. Isn't it valuable to add the correct links? I would like to create a JIRA documentation issue on this, if the community agrees. Appreciate if you can guide me to the documentation patching guide of Tuscany. Thanks. -- Best Regards, Nirmal C.S.Nirmal J.
