Use the TextField.ANY field and have a state listener whenever user enters a value the state changed will fire up, tell the user that the text field takes only numeric input.

It runs the application same as on your mobile device.

1. Go to the appdb folder in your system (for latest version in documents and settings/j2mewtk/appdb ).
2. Go to the folder that has the name of the device you were using.
3. See if you find the in.use file. If such a file is present delete it.
4. Now onwards your data will persist. just like on the device.

Above steps will work for WTK 2.5.2. Please search for the appdb folder if it isn't present at the location mentioned above.

Thanks

Hey J2ME RMS is different....
A record id when deleted just makes that record inaccessible ! you cant read it again nor edit it. hence if you want the size to reduce delete the whole record store and write all the records again.
Read some book abt J2ME RMS or better read the java docs for deleteRecord of RMS.

Thanks

Hi

Please take a look at J2ME Polish Library.

It has most of the Container structure that you are using albeit ported to j2me.

Thanks

see sharing knowledge shaved off so many days of valuable time...
WTK 2.5 is the best version ever till now
I guess everybody should stop using earlier versions totally

Thanks

no put in the number as follows

+94077xxx
xxx is the subscriber number

no need for 00 (international calling)

e.g :
if you want to send an sms to a number from another country say india
the number would be

+9108037382829

where +91 country code
080 local bangalore code
37382829 some subscriber number

Thanks

Hey Chetan
Please try the application on the actual device or use nokia emulator. default emulator has some serious problems.
I haven't checked your code but i can confidently say that it will work on the device.
I struggled with similar problem for a month until i checked it on the device.
Thanks

Hi I guess the problem here is not with the app receiving the problem is with the sending, is it possible to send an sms from a gsm modem with the port number (+112233434:1212 where 1212 is the port number )???



thanks

does ur server allow WAP protocol check that first also try downloading some other application from the same server, if it works then there has to be a problem with ur application.
99 times out of 100 ur server does not allow access to WAP connections.Ask ur sys admin to check into it.

Hi,
i have created one application using Wireless Tool Kit provided by Sun microsystems.
While running my application Via OTA i got this error
"OTA Error Code (20) - The JAR was not found at the URL given in the JAD. [null]"
Since WTK is not providing jar file i have created jar file by entering following command
jar cfm MyApp.jar MANIFEST.MF -C D:\j2me\midlet classes
Inside JAR file i am having MANIFEST.MF and CLASSES files\folder
After creating jar file i copied that JAR file into WTK\apps\MyAPP\bin folder.
After copying i executed "Run via OTA" feature of WTK to install application .....it is not getting installed it is giving error.I have searched in google but i have not succeded in finding where i made mistake ..If you know where i made mistake then please write to me..

Thanks in advance for your suggestions

U need to create a package from the WTK, use the ktoolbar to do this (Project-->Package-->Create Package) the jad and jar files will be created in the bin file and with the right jad attributes.

J2ME applications are run in a Sandbox environment that is they are not allowed access to features outside the JVM with User written applications.
Most of the devices that are java enabled do not support .dll files. The whole application has to be in a jar format.
Whereas some Symbian devices do support both,...

will get back with the details of which devices support C++ in their JVMs later.

hi
Did u check if u have GPRS enabled and also if u have good range
