Does anybody here know if J2ME(JAVA) network programs work via NZ Vodafone?
Do they block it?

Has anybody written/used a J2ME application on their JAVA mobile phone and been able to connect to an external network/web site.

The reason I'm asking is that I wrote some code to quickly test using the SE T610 mobile phone emulation on my PC and it connects to the external web site and retrieves the required information. Lovely thus far.

If I transfer this application to my mobile and run it is doesn't work.

Thought I'd better ask before I spent hours debugging my code or thumbing through my comm setup on my mobile.

Any help or ideas would be greatly appreciated

Tom

Update: found this example code on the Sun JAVA development site that can be used to test with. This also works on my emulation but not on my mobile.

I'm using a Sony Ericsson T610 (MIDP 1.0) via Vodafone NZ.

If it is the phone Data Comms settings, does anybody know what they should be? Is it just the APN that needs to be changed or is it looking at the CID number too.

I know that you can use Java apps to connect outwards. The Z600 that I used previously worked with a Java QQ ICQ client, however I had little luck with anything else because apparently Java was limited in the network / sockets department.

In saying that, if you are trying to retrieve data from a website, make sure you have the correct APN. I always had to switch to the web gprs rather than the wap (live) one. I suspect that is the problem if you are having problems on your phone, but not the emulator.... maybe.

http://live.vodafone.co.nz can send the GPRS profiles to your phone you want.

Edit: Might have shot myself in the foot, but does it try connecting (as in ask for GPRS access, connect to WAP) and returns a server not found error?

The mobile appears to connect and this may be specfic to my phone, but it asks:

Allow Web access
Ask per access
Deny Web access

This seems to be a built in function.

Selecting Allow Web access the GPRS symbol is show and the mobile appears to hang. After a while the connection is cleared. No IO error messages.

I've provided the example code if anybody is interested in checking it out.

It does work. ... just not on my SE T610 via vodafone NZ using my current mobile settings.

cheers,

Tom

The 'ask for internet query' is built in and for a good reason: To stop java apps automatically opening your wap connection (let it be GPRS or CSD).

Try using the VFNZ Internet wap profile rather than the VFNZ Gateway / VFNZ PXT, it might make a difference as its open internet.

If you don't have it, you can install it from http://wireless.vodafone.co.nz - I know that with a few messengers (an old Java QQ IRQ messenger), you couldn't use it on the WAP apn, you had to use it on open internet otherwise no dice.

Cool.

That works. Thank you, cokemaster.

I had WAP set to Vodafone live within the WAP options.

However with the WAP options now set to VFNZ Internet, WAP services now fail.

So it's, WAP on. WAP off.

Oh well it gives me something new to grumble about.

OK, you know what my next question is. How do you get a setup that works with both?

You can't tell clients to disable their WAP service every time they want to use your J2ME service.

Thanks again,

Now we can start work on my second question :-)

Not too sure how to do that myself. My play around with my z600 (and to an extent a p910c) is that you set one wap profile for them all, you can't have Java use one profile and your browser use the other.

The exception being MMS which allows you to set a wap profile (usually the Vodafone Gateway/MMS/Live!).

The P910 allows you to select what profile you use each time you connect out.

----

The solution to stop your clients (or yourself) from having to switch Wap profiles all the time is to get accessable from the wap profile, but I don't really know much about that.

The T610 is crap for any java internet apps as they can only be run over WAP using your default WAP connection, they can't access the internet directly due to SE not implimenting the capability to do this. I managed to get a few different programs working on my T610 but there are many that won't function correctly.

Ha, ha, ha, thought oh, what the heck I'll ring Vodafone and just see what they say.

Got through to the help desk lady and no more than seconds after mentioning the word JAVA the mobile cut off. I still had a signal and my SE T610 has never dropped me before.

I'd be gob smack to think they hang up on me or dropped my call. I'm sure they didn't.
I've worked for multinational companies with hundreds of people manning help desks and in general they're very conscientious and protect us back room geeks from a lot of crap.

Just odd timing I guess. Bit of a giggle though. I knew I should of said J2ME as it has more mystery to it. :-)
