J2me midlet that reads from HttpConnection throws IOException - java-me

I'm just starting to work with j2me. I'm trying to work with HttpConnection but everytime I run my sample midlet, I'm always getting an IOException which says that there is a connection error. When I test it with the emulator of the Nokia S40 5th edition FP1 lite sdk, I don't experience that problem. I'm using a Nokia 2330 phone with gprs.

I just configure a new access point for internet over gprs settings and activated it. Check this link for the steps: http://blogs.forum.nokia.com/blog/hartti-suomelas-forum-nokia-blog/2006/11/09/series-40-and-network-configuration

Nokia QA: The application cannot be launched successfully with an error message 'Application not supported. Delete?'

My Java s40 app for asha failed the QA test with the above title. I have tried recreating the problem by download the jar file to one of the supported asha phone and the app launched successfully.
Every other things seems okay i have also used the Nokia RDA to test the app. What other reasons may be causing the failure.
Just from the Error message I can assume that the your Jar File's MIDP & CLDC version doesnt match with your S40 Asha series phone.
You need to open your editor/IDE and change to MIDP Version to 2.0 & CLDC's version to 1.1.

J2ME MIDlet appears in Gallery but not in Applications

I've written a MIDlet with J2ME using Eclipse. To test it, I transfer the MIDlet using a bluetooth connection to my Nokia 6131.
But the MIDlet (or App) just appears in the phone's "Gallery" folder.
How can i move it to the "Applications" folder (where the other J2ME Apps reside)?
Using the Nokia PC Suite should solve the problem and install the program into the "Applications" folder/menu.

Midlet throws javax.microedition.rms.RecordStoreException: error opening record store file in Samsung emulator

I'm using the Samsung SDK 1.2.0 Beta in Netbeans 6.8. I'm trying to test my midlet for accessing the record store management system.
This statement
RecordStore rs = RecordStore.openRecordStore("Store", true);
runs fine when I'm using the Nokia SDK but it throws a RecordStoreException when I used it on Samsung.
I already discovered what's wrong. I installed Samsung SDK to a different folder with spaces instead of installing it to the default folder which is "C:\Samsung_SDK_120_Beta" or to another folder without using spaces.

Push Registry not working on nokia N86 after rebooting the phone; works on N97 and Expressmusic

I have written a simple midlet that invokes itself after a socket connection from a server program. I am using Push Registry to do this. It works fine on all the test phones I have immediately after installing. but if I reboot the phone, the push registry stops working on N86 whereas it is working on the other test phones that I have viz. N97 and ExpressMusic 5800. Has anyone faced such a problem before? Any kind of help will be appreciated.
btw, after going a little deep into the specifications of these phones, I found out that though all the phones are MIDP 2.1, N86 has Symbian OS v9.3 and the rest two have v9.4. Can that be the reason for the behavior of N86 ?
I did a hard reset (press *#7370#) on the phone (N86) and everything is working properly! I still don't know what the problem was!
Find the documentation of the error in nokia page:
http://wiki.forum.nokia.com/index.php/KIJ001317_-_Push_registrations_for_Bluetooth_MIDlet_turns_off_in_the_latest_S60_3rd_Edition_devices
The phones that are affected are:
Nokia E75, Nokia N78, Nokia N79, Nokia N96, Nokia 5630 XpressMusic, Nokia 6720 Classic, Nokia 5800 XpressMusic
Worst of all, you say there is no solution.
