Java Forum / General / February 2007Json Parser anyone?
Hi I'm looking for a pull json parser (similiar to kxml). Is there anything like this out there yet? I googled but nothing comes up. More importantly a j2me version would suite me just fine. If not found, who is going to write it? you? cheers jk > Hi I'm looking for a pull json parser (similiar to kxml). Is there > anything like this out there yet?

No I want to use Json, because of its higher compression, which is important for J2ME where every byte of space counts. sending json data over the air will also speedup the app considerably.

Perhaps you would be better off using Serialized objects if size is an issue. Or, if you don't need extensibility, just send a predetermined binary format. You could also look into the java.util.Properties input/output format. Hope this helps.

Btw, one thing to consider is that I believe the GPRS packet size is 1kilobyte. In other words, if you retrieve just ten bytes (for example), a 1kb packet is still sent over the GPRS network. And one kilobyte plus a few bytes of data cause two whole kilobytes of GPRS data to be sent, and so on. The choice of something like Json/xml versus a set binary format depends quite a bit on how flexible the data you are sending is. Does it always have the same fields, in same order, in same amounts? Or is more flexibility needed? > Perhaps you would be better off using Serialized objects if size is an > issue. Or, if you don't need extensibility, just send a predetermined > binary format. Whoops, I think I just reiterated above what you say about 'extensibility'... lex > You could also look into the java.util.Properties input/output format. > Hope this helps. > Daniel.

[sNip] The format of binary data can also be quite flexible (consider, for example, DNS), but that depends on how much work one wants to put into it. Using something that's already well-known can save a lot of development time.

What's your offering price/rate? hehe free? sucks i guess i just have to write my own little parser for now. cheers >>> Hi I'm looking for a pull json parser (similiar to kxml).

Of course people can and do write free software (and 'free' in several different senses of the word), but it would be a little unusual to post here and find someone willing to write something for you, at random, on spec like that... > sucks i guess i just have to write my own little parser for now. cheers What's wrong with the Java impl given at the Json site? http://www.json.org/java/index.html lex Free MagazinesGet these publications absolutely FREE for up to 12 months.
