[postgis-users] ST_AsPNG is problematic in Java

[Paragon Corporation]

Which JDBC driver are you using and which PostgreSQL version.  You might be
affected by the escape/hex change in 9.0

Subject: [postgis-users] ST_AsPNG is problematic in Java



hello 

I am dealing with java-jpa2-postgis(raster)

I tried to get an image from postgis(raster) as:

List list_rast = session.createSQLQuery("SELECT ST_AsPNG(rast) As rastpng
FROM geoslp5 where rid=184 ;").list();

and converting object to byte[]
and 
with usual java process

ByteArrayOutputStream bos = new ByteArrayOutputStream();  
... //
bytes = bos.toByteArray ();



But resulting image file(png) is defective ?

What may the probable problems ?

Do you have any recommendations ?

regards
