Is there a gzip compression library that will work on J2ME?
回答1:
Try Jazzlib, although it's GPL, and seems like it hasn't been updated for a while. Another option is to try and lift the source from libgcj (which is what jazzlib did).
J2SE includes java.util.zip which can compress/decompress gzip files, but the MIDP 2.0 specification does not include a java.util.zip. And looking at the Java 6 source code for java.util.zip, each class seems to call native methods, which means you can't just lift what's there and download it to a J2ME device.
回答2:
Another approach would be to find a J2SE implementation and try to convert it to J2ME. I wouldn't expect it to be hard, but still it would require some effort. How about this one (jazzlib?)?
回答3:
Original jazzlib is for J2SE only.
Jazzlib ported to j2me is available here: http://code.google.com/p/staff/downloads/list?q=jazzlib
回答4:
You may want to check out: http://code.google.com/p/compress-j2me/. Uses only 7k (~5k after obfuscation). Compression is under developement.
回答5:
Have you tried this one? (I haven't, but found it when googling.)
回答6:
I've seen successful use of http://www.tinyline.com/utils/ which gives you a gzipinputstream useful for http communications.
