My blackberry 9000 bold shows jvm error 102 plz guide how to fix it .its not woking only white screen with this error shows when i on the phone.

Hi, i think if you try resetting it, it might work .
There are three ways you can reset the black berry phone.

1) Soft Reset - simply press the ALT+RIGHT SHIFT(CAP)+DELETE keys.

This reset stops all applications that are running on the Blackberry and will help if you are having problems connecting the device to computer. This reset will not erase any information from your device.

2) Double Soft Reset - this reset is almost equivalent to a full hard reset. First perform a Soft Reset as outlined in Step 1.

As soon as the screen is no longer black - repeat the steps once again exactly as before.

This takes you to another screen showing an hour glass. Allow the device to reset. This helps if the device has suffered a more serious error. Be aware you may loose some information from your device. A backup is advised prior to proceeding if at all possible.

3) Hard Reset - this is the full blown reset and will fully reset the device to help resolve critical errors with software or hardware. Again back up important information before proceeding if possible.

Note: For RIM models 850, 857, 950, or 957, you must insert the end of a paperclip or similar blunt object into a small recessed hole on the back of the unit and depress the switch inside. The device will reboot and be hard reset.

Other Models: With the device turned on - remove the battery for 30 seconds or more. Now replace the battery. The device will reboot and be hard reset.

Blackberry Pearl: To reset to factory defaults enter 'Options' from the main menu. Scroll to Security Options and press the trackball. Choose 'General Settings'.

Press the left soft key, then scroll to "Wipe Handheld" with the trackball and press the trackball. To initiate the factory reset, your phones security code may be required in order for the process to complete. Your phone will now be restored to its original settings on leaving the factory.

A hard reset can be achieved with the Pearl in the same way as outlined at Step 3 by removing the battery.

Be aware that resets such as these may erase data, such as contacts, ring tones, pictures, text messages and stored Internet files and emails. Make sure to back up important information beforehand if at all possible. You can obtain software to back up the device to your computer directly from Blackberry right here.

Hope this Tip helps.
