or can I use convert, setColumn etc. from org.apache.cocoon.util.JDBCTypeConversions ??Guess so. But the input object must be of a supported type (the sample uses the raw-request-param module for this).

Hello Chris, thanks for the quick reply. To get the image into the database i'm using the following
importPackage(Packages.org.apache.cocoon.util);
if (my_image != null) { var ps=conn.prepareStatement("UPDATE my_table SET image=? WHERE image_id=?");
ps.setString(2,imageID); ps.setBinaryStream(1,my_image,my_image_size);
ps.executeUpdate();
ps.close();
}
To get the image out:
....
importPackage(Packages.org.apache.cocoon.util);
var ps=conn.prepareStatement("SELECT image FROM my_table WHERE image_id=?");
ps.setString(1,imageID);
var rs= ps.executeQuery();
if (rs!= null){
if(rs.next()){
var result = rs.getBinaryStream(1);
}
rs.close();
}
ps.close();
....
How to I have to process the resulting bytearray (var result = rs.getBinaryStream(1);) to get an image back ?
