Is it possible to know which bluetooth services are available with a MIDlet

...Bluetooth Services like Serial Port Support, Obex File Transfer, Dial-up Networking...
I've already try to search with "getProperty()" (api.version, n� max. of devices...) but it awlays return "null" !!!!. I'm a beginner in j2me BLUETOOTH. Thanks!

Varies from phone to phone.
I believe it is recommended to use a port between
16001 and 16999 on a J2me app as these are almost
always free.
In my opinion the best way to find out what will work
and what won't is to create a small app which will
try to create an SMS connection on a specified port
(specified through something like a textbox) and
which will display something indicative if an
IOException is thrown during the process of
creation.
Most manufacturers usually also have documentation on
this on their developer sites...hi i have a similar problem with they guy above
i have installed a camera network wich has acces to web from port 8080 i have access from any computer that has internet but when i connect with the java app provided from the cameras company it throws "java.lang.securityexception untrusted midlet attempted to connect to a restricted port" i was wondering if i change te port tha i connect will i have access from that program?? and if yes wich port should i use? i am asking because its not easy to have access to the router to change the port forwarding settings thank you in advance

Iphone configuration utility-- possible to restrict which EAS options are available?

Hi all-- I'd like to be able to use the iPhone Config Utility (am on 3.4 currently) to create a profile that restricts the user to accessing only some sections of an Exchange account, like being able to see/use the account's Contacts but not the Mail/Calendars/Reminders, etc. Anyone know if this is possible? I currently do not see any way to do this.
If not, any suggestions on how to enable EAS access to just the Contacts in an Exchange account? I can use CalDAV for Calendar info but CardDAV for access to Exchange Contacts is not supported... (reason for restricting this is I am trying to enable a user to have access to her boss' Calendar & Contacts but not Email...)
Many thx in advance for any insight,
Charlie

Ipcu .ipa installs were opened up for folks building internal business tools, hobbyists go want to put their code on their friends devices.... Etc...code that doesn't belong on the AppStore because a developer may not have wanted the code to be for public use. Of course when the kids found out you could do it they would do it too...which isn't good especially if paid apps are getting passed. Then they designed the app panick, which is what you saw when you tried to install .ipas without the proper execution authentication to stay resident on the springboard.
It's woould behoove you to take interest in Apple Configurator.
It brings the best of Xcode, ipcu And iTunes in one UI, basically you own little MDM tool. You can set it up to update firmware, sequentially name, install from backup, push .mobilcobfig (although you still need the local authority on the device to accept..standard security protocol and a good idea anyway, volume install apps after you have imported a key, deploy restrictions, but the best thing is using it with mountain lion server and pushing notifications, updates and policy or provisioning OTA just like the 'MDM companies' charge thousands of people millions of dollars every year.
Use this opportunity to deploy excellence to your customer. Give them a good user experience, address their issues, document the challenges they had and the solutions you provided them, and put your ios Deployment book somewhere people can read it, and when you get that job offer from some other company who wants organic MDM instead of getting ripped off by those other guys...your replacement will be able to read a little and pick up where you left off.

I have synced two devices in FF. Is it possible to know which computers are synced using? I am worried about someone figuring out my email address and password.

HI nilhanw,
No currently there is not manage devices, only manage device. However changing the password will change the certificates on all the devices within less of an hour.
I hope this helps.

Need to know if someone can hack into my MacBook Pro even if it's not connected to the internet and both Wi-fi and Bluetooth services are off? Can someone enter my system even if the settings at System Preferences > Sharing are all off?

Yes,
Through Bonjour, Apple's open source zero configuration networking.

And you can't turn it off or your computer won't work, however saving grace is the hacker has to be pretty close to your machine to do it.

This sounds like a price match question. Without knowing all the details, it sounds like a yes for the Westinghouse, but I would encourage you to read the price match policy link here:

If all you care about is 1080p definition and an HDMI input at a $300 price point then this tv should suit your needs. (As a bonus it has 120Hz refresh for smoother action scenes.)http://www.bestbuy.com/site/Westinghouse+-+40%26%2334%3B+Class+-+LCD+-+1080p+-+120Hz+-+HDTV/5772998....

Determining which services are associated with which programs

In the Services Preferences, Services submenu, how does one determine which services are associated with which programs?

Danged if I know! I just took a guess and enabled the ones I wanted, then tried what came up to see which program launched to do it. Some are easy: "Copy to Tex-Edit Plus" will obviously use the program Tex-Edit Plus. But I have no idea which program owns "New Document Containing Selection" and since I want TextEdit to handle that sort of thing I unchecked it, and simply checked "New TextEdit Window Containing Selection" because that's obviously TextEdit. I left "New Window with Selection" checked, and then tried it, and TextWrangler launched. OK, I do sometimes use it, so I left it checked. But it would be nice if it declared itself in the Service list so you could tell what program is going to do which thing. However, that is not Apple's fault--it is the fault of the application, someone just didn't bother to write a proper line for the system to display that would tell the user what application it is. That is probably because in the "old" Services menu items were arranged in folders by application, so there was no special need to have the service itself declare to whom it belonged. Perhaps this situation will change as applications are updated for Snow Leopard.
I happen to know that the Services are declared to the system by the application, and the place this comes from is the Info.plist of the application, which is inside the application bundle. You can open this and check the plist: the service will be listed in the NSServices section in the NSMenuItem default field. Not something most people would ever want to do, you have to open the bundle then open the plist with Property List Editor.
Meantime, I think trial and error is the only way to tell where the service is coming from. I would be delighted if someone knows otherwise.

There's no list available from your end. If you're out of authorizations, use the Deauthorize All function.

After Creating a new document or editing an old document in Pages on my iPad I no longer see the changes in Pages on my iPhone. iCloud services are on with both devices.

Just thought I'd add my solution, I decided to go with WebDAV and I think it actually works better than the iTunes way, the steps are pretty much the same but avoiding the iTunes interface just makes things easier and faster.
I followed this guide but it does have a small mistake in the httpd-dav.conf file, on line 2, where it's WebServer/WebDAV">, it should be <Directory "/Library/WebServer/WebDAV">.
The tricky part is setting permissions which if wrong will give you errors when connecting with the iPad, I opted to set all to Read&Write since my home network has a hardware firewall. Another convenience was to add an alias to the webdav share on the Desktop.
I'm still expecting the call from Apple but even if they fix the iTunes I'm sticking with WebDAV, atleast until I see what's new with iOS5 and iCloud this fall which should bring true sync for documents (I'm hoping that they will offer encryption with my own keys, if not, then I'll probably keep using WebDAV).

How does one tell if the J2EE services are running with Unlimited

How does one tell if the J2EE services are running with Unlimited
security? We have applied the export Policy to the server but we do notsee any reference to it running with it. .we apply the Service packs SAP now upgrades that JAVA as well . Do that process treat the JAVA
lib/security area correctly.

Just out of curiosity... Is there something you do
like about Mac/Apple?
To answer your question: no, not really. However, the points that I made here were about Safari and accompanying utilities, not about Apple in general.
If it makes you feel any better, I am just as, or even more, critical of Micro$oft as the occasions arise...Windoze Vista is the most recent occasion and has given sufficient reasons and opportunities to vent my spleen that I actually have eased up on Apple, politicians, nut-case religious extremists, cell phone owners, and the Department of Homeland Paranioa, etc., due to an exhaustion of creative energy.
