Hi,
I made a test file with one point and one attribute of each selectable data
type. However, OpenJUMP is not totally ready for handling all those.
Saving the JML file as shapefile stops to the following error:
java.lang.Exception: ShapefileWriter: unsupported AttributeType found in
featurecollection. : BIGINT
at
com.vividsolutions.jump.io.ShapefileWriter.writeDbf(ShapefileWriter.java:537)

com.vividsolutions.jump.workbench.ui.task.TaskMonitorManager$TaskWrapper.run(TaskMonitorManager.java:152)
at java.lang.Thread.run(Unknown Source)
Next I tried to edit the schema and remove the BIGINT attribute but it was not
so easy. Changes in the schema can be confirmed only after removing all the
attributes of the following data types first:
CHAR
VARCHAR
LONGVARCHAR
TEXT
BOOLEAN
BIT
SMALLINT
TINYINT
LONG
BIGINT
DECIMAL
NUMERIC
BIGDECIMAL
FLOAT
REAL
TIME
TIMESTAMP
The error if any of the above data types appears in the schema is like:

Here is how GDAL understands our new attribute types:
ogrinfo datatype_test.jml -al -so
Had to open data source read-only.
INFO: Open of `datatype_test.jml'
using driver `JML' successful.
Layer name: dttest

real_attribute: String (0.0)
date_attribute: DateTime (0.0)
time_attribute: String (0.0)
timestamp_attribute: String (0.0)
object_attribute: String (0.0)
Most new types are converted into strings by now. I think I could sponsor the
GDAL development if someone writes the mapping between OpenJUMP datatypes and
GDAL datatypes. I am not sure what the GDAL datatypes are but the following
list might be right:
1. boolean (GDAL >= 2.0)
2. character(field_length). By default, field_length=1.
3. float(field_length)
4. numeric(field_length, field_precision)
5. smallint(field_length) : 16 bit signed integer (GDAL >= 2.0)
6. integer(field_length)
7. bigint(field_length), 64 bit integer, extension to SQL92 (GDAL >= 2.0)
8. date(field_length)
9. time(field_length)
10. timestamp(field_length)
Obviously 'string', and 'real' are supported and then I believe that there is
support for these three:
'integer list', 'double list' and 'string list'.
However, I have not yet realized if we need all these data types and how
generally they are supported in the surrounding GIS and computing world.

Hi,
I managed new attribute types introduced by Ede in shapefile and jml drivers
(BOOLEAN and LONG are managed as "Logical" and "Numeric,21,0", and other types
are managed as one of the former types).
Please use and test these new types, especially with shapefiles.
Next step is to introduce these types in PostGIS database driver.
