Goal: Read a blob image from an Oracle database and render it on an html
page using the struts framework.
I've never found a good way to do this and I was hoping someone had a
"best practice" suggestion.
I have no trouble getting the image from the database. However, I wonder
if there isn't a better way to display it rather than writing it to a
physical file and then rendering it. I'm using the <html:img tag to
display the image now.
All help appreciated.
J.
ImputStream pictureStream;
ResultSet rs;
// create the query and execute it ...
// get the result
pictureStream = rs.getBinaryStream("picture");
// I can write it to a physical file
File pictureFile = new File("/temp/picture.jpg");
try
{
FileOutputStream out = new FileOutputStream(pictureFile);
int chunk = 0;
while( (chunk = pictureStream.read()) != -1)
{
out.write(chunk);
}
out.close();
out.flush();
}
catch(FileNotFoundException ex)
{
System.err.println("selectionForm.populate.picturefile: " +
ex.getMessage());
logger.error("selectionForm.populate.picturefile: " +
ex.getMessage());
}
catch(IOException ex)
{
System.err.println("selectionForm.populate.picturefile: " +
ex.getMessage());
logger.error("selectionForm.populate.picturefile: " +
ex.getMessage());
}
