I'm also adding a preference page so you can set whether or not to create an index.

So I've just added 2 ways to do this.

In order to use these methods you either have to get the latest sdk from the nightly build:

or check out the repository and run using that.  Here are some instructions.

Once you have these it is really easy:

1) ShpPlugin.getPlugin().setUseSpatialIndex()  will set it so spatial indices will not be created for the shapefiles.

2) If you are creating the ShpService object programmatically you can create it using a parameter map that has the createShapefileIndex set to false:
Map<String, Serializable> params=new HashMap<String, Serializable>()
params.put(IndexedShapefileDataStoreFactory.CREATE_SPATIAL_INDEX.key,false);
params.put(IndexedShapefileDataStoreFactory.URLP, new URL("file://pathtoshapefile.shp"));

Hope this gets you on the right path.

At the end I had to reorganize all the work since the version of UDIG I was using had some incompatibility with the ShpPlugin (no more layers went rendered!!!).
Now I'm working with the right version of udig-SDK-win32-x86.zip (I downloaded it two days ago: 2006-06-27)
But still I cannot stop the indexing of shapefiles.
Before I tried with
    ShpPlugin.getDefault().setUseSpatialIndex(false);
in the start method of my plugin (may be this is a wrong place where to put it?).
Then I tried with the preference page. Having the checkbox unchecked still create the index of the shapefiles.
Any suggestion? I'm doing something wrong?
Thank you very much
