Zipping unpacked OpenDocument in Windows

[fhucho]

Hello,
I try to pack unpacked and modified OpenDocument file (specifically .ods), using the java.util.zip package back into .ods. My code works only in Linux, not Windows.
For zipping, I use this code:

String[] files = listOfFiles( "uncompressedOds\\"); 
byte[] buf = new byte[1024];
String zipFile = "table.ods";
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFile));
// compress the files
for(int i = 0; i < files.length; i++){
    ZipEntry zipEntry = new ZipEntry(files[i]);
    out.putNextEntry(zipEntry);
    if(!new File("uncompressedOds" + File.separator + files[i]).isDirectory()){
        FileInputStream in = new FileInputStream("uncompressedOds" + File.separator + files[i]);
	int len;
	while((len = in.read(buf)) > 0){
	    out.write(buf, 0, len);
	}
	in.close();
    }
    out.closeEntry();
}
out.close();

The problem is, that the zipped ods file cannot be opened with OpenOffice - it displays a message that the file is demaged, and asks whether I want to repair it. After I select to repair the file, it opens and is entirely OK.
In Linux the created ods file is not demaged - that's very strange.
When I unpack the ods file (which my program created) in Windows (using gnu unzip) and pack it back using WinRar - the ods is then OK.
In both WIn and Lin I use Java 6.

Not sure if this will fix your problem but you may want to call flush before closing the ZipOutputStream. Some classes are picky about the need to call flush before calling close.

Thanks, but unfortunately it didn't help...
