oh, and you set the methods at the entry, the setter method on SevenZOutputFile
provides the default for all entries that don't override it.
{code}
public static void main(String args[]) throws Exception {
String t = "Das ist ein kleiner Test!";
SevenZOutputFile sevenZOutput = new SevenZOutputFile(new
File("/tmp/test.7z"));
sevenZOutput.setContentCompression(SevenZMethod.LZMA2);
SevenZArchiveEntry entry = new SevenZArchiveEntry();
entry.setName("test");
sevenZOutput.putArchiveEntry(entry);
sevenZOutput.write(t.getBytes());
sevenZOutput.closeArchiveEntry();
entry = new SevenZArchiveEntry();
entry.setContentMethods(Arrays.asList(new
SevenZMethodConfiguration(SevenZMethod.COPY)));
entry.setName("test2");
sevenZOutput.putArchiveEntry(entry);
sevenZOutput.write(t.getBytes());
sevenZOutput.closeArchiveEntry();
sevenZOutput.finish();
sevenZOutput.close();
}
{code}
