Hello, I'm getting the following message when I try to open a ppt I
saved after it was streamed from a servlet:
PowerPoint can't open test.ppt because part of the file is missing
Here is my servlet code. It simply creates a slide show from an input
stream and adds an image to slide 15:
ServletOutputStream out = response.getOutputStream();
InputStream uploadedStream = null;
ByteArrayInputStream bais = null;
// a little clumsy here
ByteArrayOutputStream baos = new ByteArrayOutputStream();
fp.writeTo(baos);
byte[] ppt = baos.toByteArray();
bais = new ByteArrayInputStream(ppt);
SlideShow ppt = new SlideShow(new HSLFSlideShow(bais));
byte[] pngArray =
controller.writePNGToByteArray(DOMDocument);
int index = ppt.addPicture(pngArray, Picture.PNG);
Picture pict = new Picture(index);
pict.setAnchor(new java.awt.Rectangle(195, -11, 400,
633));
Slide slide = null;
slide = ppt.getSlides()[14];
slide.addShape(pict);
DOMDocument = null;
}
ppt.write(out);
out.flush();
out.close();
It's all pretty simple. Perhaps it's my handling of the ByteArray
Input/Output Streams.
Any help would be appreciated.
Regards,
Eric Hamacher
