Ja tiez pouzivam komercnu kniznicu IPWorks, tiez kvoli
sifrovaniu a WinZipu. Problem je v tom, ze u zakaznika
na predvadzacom serveri je JDK 1.4 a na ostrom JDK 1.5
a IPWorks funguje spravne len s JDK 1.5.
Preto na predvadzacom serveri pouzivam java.util.zip
(a sifrovanie tam proste nefunguje) a na ostrom
serveri pouzivam IPWorks.
Mohli by ste mi prosim poslat nejaky priklad ako
kodujete nazvy suborov v IPWorks? Na stranke /n
software som v tomto ohlade nic nenasla a zo supportu
sa mi este neozvali. Ja nastastie potrebujem zipovat
len na nemeckych Windowsoch. Jedine co asi budem
musiet zistovat je, ci sa pouziva OEM 850 alebo 858.
Dakujem. S pozdravom
Radovana Straube
P.S. Pripajam aj kod ako pouzivam IPWorks
/**
* Compress a directory, encrypt the zip file
* @param _sSourceDir a source directory
* @return path to compressed and ecnrypted
archive
*/
private String compressAndEncryptDir(String
_sSourceDir, String _sPassword) throws IOException {
String sZipArchive = extractArchiveName(_sSourceDir);
try {
if (s_oLogger.isDebugEnabled()) {
s_oLogger.debug("compressAndEncryptDir->sZipArchive:
" + sZipArchive + ", dir: " + _sSourceDir);
}
Zip oZip = new Zip();
oZip.setArchiveFile(sZipArchive);
oZip.setRecurseSubdirectories(true); //demo
recurses into subdirectories
oZip.includeFiles(_sSourceDir + "*");
oZip.setPassword(_sPassword);
if (s_oLogger.isDebugEnabled()) {
s_oLogger.debug("compressAndEncryptDir->password: "
+ oZip.getPassword());
}
oZip.compress();
} catch(IPWorksZipException oExIP){
s_oLogger.error(oExIP.getMessage(), oExIP);
throw new IOException("IPWorksZIP exception
thrown: " + oExIP.getCode() + " [" +
oExIP.getMessage() + "].");
}
return sZipArchive;
}
