Commons Compress 用以实现将文件压缩或解压成 tar、zip、bzip2 等格式。[code]下面代码将文件压缩成zip格式：
ArArchiveEntry entry = new ArArchiveEntry(name, size);
arOutput.putArchiveEntry(entry);
arOutput.write(contentOfEntry);
arOutput.closeArchiveEntry();
Zip文件的解压缩：
ArArchiveEntry entry = (ArArchiveEntry) arInput.getNextEntry();
byte[] content = new byte[entry.getSize()];
LOOP UNTIL entry.getSize() HAS BEEN READ {
arInput.read(content, offset, content.length - offset);
