storing uncompressed zip files

I am using ZipOutputStream to create an archive of (among other things) image files. Since the images are already compressed, I would like to archive them in STORED (uncompressed) mode. But when I do so, I get the following exception from ZipOutputStream.putNextEntry():

STORED entry missing size, compressed size, or crc-32

The size is there; what it wants is the checksum value. If I archive the images in DEFLATED mode, I have no problem.

Do I really need to calculate the checksum value myself before archiving an uncompressed file?

Did you try this?

public void setLevel(int level)

Sets the compression level for subsequent entries which are DEFLATED.

The default setting is DEFAULT_COMPRESSION.

Parameters:

level - the compression level (0-9)

That has no effect, nor should it: the documentation says it only concerns DEFLATED (compressed) mode.
