Hi,

You are right. The SCA Composite Designer can't construct a good diagram with this kind of composite file.
It's necessary to parse the class calculator.AddServiceImpl to discover that it implements a Service defined by the interface calculator.AddService. 
I agree that it's a relatively strong limitation, but, as I said before, we work on this issue and I hope that we will be able soon to provide a Designer for this.

I'm looking forward to your listing of issues ;)

Thanks Dan.

Hello Stéphane,

Thanks for replying and glad to see such a great response time.

Let me continue this discussion on stp-dev@xxxxxxxxxxx, but I will cross post to dev@xxxxxxxxxxxxxxxxxx to let everyone know to move the discussion there.

Let me also preface this by saying, I have not read the SCA tools manuals or built this composite top down, I just tried reading in a Tuscany composite file (Ganymede, Tuscany 1.3.2, recent SCA tools plugin), so I might be not following the directions. I view the composite file below in an Eclipse project, I select "Initialize SCA Composite Diagram file", and the diagram comes in an editor pane.

The 2 components are laid out one on top of the other. There is no service graphic on the AddServiceComponent. There is no wire from the Calculator reference to the Add service.


<?xml version="1.0"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
  xmlns:sample="http://sample"
  name="Calculator">

 <component name="CalculatorServiceComponent">
    <implementation.java class="calculator.CalculatorServiceImpl"/>

    <reference name="addService" target="AddServiceComponent"/>
 </component>

 <component name="AddServiceComponent">
   <implementation.java class="calculator.AddServiceImpl"/>
 </component>
</composite>


Let me know if my file is wrong or I have misused the tool.

Thanks, Dan Becker

What are your layout problems?

If you have problems or ideas to enhance SCA Tools, don't hesitate. You can
share your experience on eclipse.stp.sca-tools and submit bugs in the
Eclipse bugzilla.

I cross post this post to stp-dev, it can be interesting too for STP.

Best regards,

Hi Doug,

Dhaval Chauhan and I recently installed this tool and have started looking
at using it with the Tuscany samples. I joined the usenet group for
eclipse.stp.sca-tools, and I hope to post any Tuscany-related questions or
issues there.

My initial use of the tool sounds a little similar to you. I imported the
sample-calculator composite and found some layout problems and also some
problems with going from the graphics into the composite. I intend to do a
more formal listing of the issues.

Somebody with the spare time (heh) should take a look at the SCA Tools
from the SOA Tools Project (http://www.eclipse.org/stp/sca/index.php).
The tool has some layout problems, etc., but it does render a .composite
file as a visual diagram. The tool uses libraries from Apache Batik to
export the diagram as a PNG, JPEG, SVG, GIF or BMP.; right-click on the
diagram, then choose File-->Save as Image File... and then choose your image
format and file name.
On my "List of projects I would love to hack around on if I had a paid
sabbatical" is taking that code and creating a command-line tool to do the
layout, build the diagram, then export it to a graphic.  At one point doing
that with an XSLT stylesheet was on the list, but it seems like the SCA
tools have done most of the heavy lifting required.
Loading the .composite files into the SCA tools and saving the diagram
might be easier than using PaintShop or Inkscape or something like that.

Open Office SCA diagrams was - Re: [DISCUSS] Tuscany 2.0 themes?

Personally I get frustrated when I read or make Tuscany demos or
presentations and the simple composites must be created with PaintShop or
some non-tech tool.

This may not be quite what you had in mind but a while back someone
created an SCA diagram stencil for Visio [1], lots of people wont have Visio
so maybe we should create a similar template for OpenOffice Draw and make
that available on the Tuscany website so anyone can use it to create good
looking pictures. (Disclaimer, i know little about OpenOffice Draw but
googling it it does seem to have a stencil facility)

My starting point is here (
http://svn.apache.org/repos/asf/tuscany/sandbox/slaws/scatemplate.odg).
Nothing clever though, just cut and paste drawing from this point. haven't
worked out how to make these 1st class symbols.
I did work out how to add different line ends and create custom formats
but that didn't stretch to whole symbols. Maybe someone else knows how.
