Hello, the code that creates that message is:
...
if (shapeType==SHP.NULL || shapeType > 28){
logger.info("El shape ="+index+ " de la capa ="+toString()+" es null");
return null;
}
...
Have you added the source code of gvSIG or only the JAR files to your workspace?
Can you find out the value of shapeType?
Maybe you are using a rare shapefile?
Try another one or try this one:

Are you using gvSIG 1.1 or gvSIG 1.10 ?

Juan Lucas Domínguez Rubio

Hi Juan,
nearly... when I load the layer the IndexedShapeDriver says that each polygon
in the file is null... why? :-( Does someone know where the failure could be?
(INFO [Thread-6] (IndexedShapeDriver .java:220) - El shape =219 de la capa
<mailto:...IndexedShapeDriver@11ed166> ...IndexedShapeDriver@11ed166 es null)

Hello,
Very interesting, thanks.
So you are very close to having a gvSIG layer in Eclipse, aren't you?
You can instantiate a layer by code and add it:
map_control.getMapContext().getLayers().add(...)
Have you done that?

Dear Juan,
I think we have found a really easy way to use the AWT-components in SWT and
Eclipse. The solution is the "albireo"-project. It provides a SwingControl
which enables you to use the AWT-components very easy. Here is my
implementation which seems to work fine:
public class View extends ViewPart{
private MapControl mapControl = null;
private SwingControl swingControl = null;
public void createPartControl(final Composite parent){
swingControl = new SwingControl(parent, SWT.NONE){
@Override
protected JComponent createSwingControl(){
View.this.mapControl = new MapControl();
return View.this.mapControl;
}
@Override
public Composite getLayoutAncestor(){
return parent;
}
}
@Override
public void dispose(){
if(View.this.swingControl != null){
swingControl.dispose();
{
{
}
Maybe this could be the solution :-)
Cheers
Tobias

Hello, Tobias.
I have realized that there is a big difference between the JVM I used in the
mobile devices and the JVM you are going to use: in my case, the AWT classes
simply were not available, but in your case the classes will be available but
will not integrate easily in the Eclipse SWT context.
So one possible way to integrate gvSIG in the Eclipse RCP application is
drawing the map in a AWT image (for example BufferedImage) and then convert the
image into a SWT image (I'm sure this is easy and fast) and paste it in you
Eclipse SWT canvas. In this way you will probably be able to re-use the gvSIG
libraries easily.
Just an idea...
Regards,
Juan Lucas Domínguez Rubio

Asunto: AW: [Gvsig_english] Eclipse RCP with gvSIG
Hola César y Juan! :-)
Thanks a lot for your thoughts and experiences. I believe the combination of
gvSIG and RCP will matter a couple of hours of work for me :o)
I am just starting up with gvSIG and will investigate what will be necessary to
satisfy our needs. Unfortunately we do not have the choice to match our
requirements without Eclipse RCP. I will tell you about my improvements.
With best regards
Tobias

Betreff: Re: [Gvsig_english] Eclipse RCP with gvSIG
Hello, Tobias:
I don't have much experience in 'improper' integration between gvSIG and
Eclipse SWT (I mean, things like embedding AWT controls in a SWT context or
using some kind of library wrapping), but I have done some tests regarding
gvSIG libraries in a SWT context.
As you perhaps know, the application gvSIG Mobile is using a simplified version
of gvSIG 1.X mapping libraries.
I wrote a little 'unofficial' version of gvSIG Mobile for Linux devices (such
as the Openmoko phone or the Nokia N810 tablet) with less functionalities than
the 'official' gvSIG Mobile but including some other new features.
At that time, I found no JVM for those devices that could use the AWT classes
(used by gvSIG and gvSIG Mobile). Instead, the Eclipse SWT library was working
fine on them, so I changed the gvSIG mapping libraries to make them graphic
context independent, and then reimplemented the needed classes to use Eclipse
SWT classes. Essentially, I did this:
- Take the mapping library of gvSIG 1.X (libFMap) and replace all the
occurrences of the classes Graphics2D and Image (this includes all the
BufferedImage), with some Java interfaces created by you. So, for ecample in
the FLyrVect class, instead of:
public void draw(Graphics g, ViewPort vp) throws FMapDriverException { ... }
you will have:
public void draw(IGraphics g, ViewPort vp) throws FMapDriverException { ... }
(IGraphics is a new Java interface)
Before doing this, I removed a lot of drivers from libFMap which were not
interesting. I also applied this transformation to the WMS driver and added it
to my workspace.
- create a new Java project with those Java interfaces (the new libFMap will
depend on this project)
- create another Java project containing an implementation of those Java
interfaces. Here is where you would use the SWT library to implement all the
needed methods (such as drawing a line, creating an image, pasting an image on
a graphic context, etc.)
- then, at the beginning of the application, you create a SWT-based factory
that is able to instantiate all those SWT-based graphic resources and methods,
and use it across the application.
There are a lot of other important things I had to do from scratch, for example
the table of contents (TOC) and of course all the GUI (dialogs). I also split
the libFMap project in different parts (libGeom, libRender, etc). This was the
resulting workspace:
https://svn.prodevelop.es/public/labs/gvsigmobileonopenmoko/trunk/
and these are a couple screenshots of the aplication:
http://gvsigmobileonopenmoko.files.wordpress.com/2009/04/carta_2007.jpg
(WMS layer + 2 little shapefiles)
http://gvsigmobileonopenmoko.files.wordpress.com/2009/07/nokia_31468.jpg
(ArcIMS layer)
I have never done it myself, but I presume in the Eclipse RCP-based
applications you eventually will have to use the SWT graphic classes I used,
especially:
org.eclipse.swt.graphics.GC
org.eclipse.swt.graphics.Image
So that would be one way to properly integrate gvSIG in the Eclipse RCP
platform.
After my little experience, I think that the Eclipse SWT graphic context is
less powerful and slower than the AWT Graphics2D class. I did not investigate
it deeply but I think AWT has better access to the device's graphic hardware
capabilities and therefore drawing is faster and more flexible.

Juan Lucas Domínguez Rubio

Eclipse RCP with gvSIG
Hello,
I am interested in your experiences with the gvSIG software embedded in Eclipse
RCP. I want to start up a project using these technologies. Anyone did this
before? Are there some points I have to focus on?
Thank you very much!
Best regards,
Tobias
