Hi Eros,
I'm a little confused as to what you are asking. If you want to read
the attributes file (.dbf) and get the attributes for each shape in
the shape file, the DbfTableModel can do that for you. If you are
using the EsriGraphicList to read the shape file, it'll read the dbf
file for you and store the DbfTableModel in the EsriGraphicList
attributes under the ShapeConstants.DBF_ATTRIBUTE key. You can also
retrieve it with the esriGraphicList.getTable() method.
Once you have the DbfTableModel, you can ask it for the column
information so you know what the attributes mean. Then, you can ask
for records from it. They are in the same order as the OMGraphics on
the EsriGraphicList. You can ask each OMGraphic for its
ShapeConstants.SHAPE_INDEX_ATTRIBUTE and it will give you the index
for its record in the DbfTableModel.
>From there, I guess you would create the tags you need to write those
attributes out in the GML entry for each feature.
Hope this helps,
Don
