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

Hi,
I'm the lead of SCA Tools.
What are your layout problems?
For me, one of the main issue is that some information is lacking on the graphical representation when you load Tuscany samples. That's normal. The Java code of the Tuscany samples contains a lot of information needed to have a complete graphical representation. These samples are developed following a bottom-up approach.
The problem is that, currently, the SCA Composite Designer is designed for a top-down approach. So, the code isn't introspected. All the information need to be in the composite file.
However, I'm working with Frascati guys to use their code on SCA Tools. Frascati is an SCA runtime (OW2 project) that has already code able to introspect Java class to complete the composite file. We plan to contribute this code to SCA Tools at the beginning of 2009. So, I hope that we will be able to support the bottom-up approach in the SCA Composite Designer soon.
Why don't we use the Tuscany code introspection mecanism? Because Frascati and a large part of the SCA Tools project were implemented in the scope of the SCOrWare project[0] funded by the French Research National Agency (ANR).
In addition, concerning Tuscany, we plan work with haleh mahbod and Dhaval to upgrade SCA Tools to support Tuscany 1.3.
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,
Stephane Drapeau

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.
