Hi,
I am trying to write features from shape file into DGN file from my
application. I am using swig generated java interfaces. I am able to
write features with point and simple line geometries without any problem
but when it comes across a feature which is either multilinestring or
multipolygon with very large number of vertices more than 2000 it
crashes. Following is a error log generated.
When I debuged gdal implementation and my application I found that the
ogr implementation does create the geometry object but when it returns
from the function it throws following access violation exception. I have
searched the couple of post on net and found that it is related with
size of data.
Any help or suggestion in this regard is appreciated.
Please reply if you need more information if above is not sufficient.

Nilesh,
For the most part the java vm crash info doesn't help me much. But if the
crash is specifically in CreateGeometryFromWkt(), perhaps we can reproduce a
problem at the C++ API level. Can you provide the WKT string that triggers
the crash (perhaps as a zip'ed text file directly to me?)
What version of GDAL/OGR are you using? Where did you get your build
of GDAL and the java bindings?
If I can't reproduce it at the C++ level, we will likely need to isolate
a demonstration of the problem in a minimal Java program, and try to
establish the particulars of your software version, etc.
Best regards,
