[WARN] [rms ] javacall_file_open: _wopen failed for: ... _delete_notify.dat

I can see your head ... You say "I hope there's a solution." It's funny but I realized that some visitors arrived on this blog after placing a google search, mainly including the keyword '_delete_notify.dat.'

The problem is that the page of this blog that has that keyword does nothing to solve this problem. I decided to tour the java forums and wow! no walkthrough. So I have a little something for you.


What is that file  _delete_notify.dat. ?

Weed I do not know ...

No, What you should understand is that:

1 - this issue does not affect your java code

2 - The NetBeans IDE uses as seamlessly deploy OTA when you launch your MIDlet. They thus create a more or less temporary URL that issues the fichier.JAD to your mobile virtual (emulation of the MIDP wireless toolkit).

3 - fichier.JAD says is supposed to be downloaded before execution of the program on the emulator. Notice the line above your error in the console:


Starting emulator in execution mode
Installing result from: http://127.0.0.1:1254/VotreMIDlet.jad


[WARN] [rms] javacall_file_open: _wopen failed for C: \ Documents and Settings \ be \ JavaME-sdk \ 3.0 \ work \ 0 \ appdb \ _delete_notify.dat


- This problem occurs when downloading the emulator to fichier.jad Mobile Wireless Toolkit

4 - Finally, delete_notify is an attribute present in the fichier.jad

So what can you do?

Two smalls things :

- open Fichier.jad  with notepad and delete the lines as:

"MIDlet-Install-Notify, MIDlet-Delete-Notify, MIDlet-Delete-Confirm" (Unless you need it)

- Create with notepad an empty file and name it "_delete_notify.dat" ... copy and paste it exactly where the error claim it. it should work.

How to install offline Maps on your BlackBerry using TrekBuddy 0.973

BlackBerry smartphones are handy for GPS navigation helped by the excellent BlackBerry and Google Maps applications. When you are out of range of a data signal both these applications are unable to continue to provide a map. With TrekBuddy you can use offline maps, from Google and elsewhere, record route speed and waypoints, or use your phone as a direction finder. TrekBuddy is a great, freeware application developed by Kruch a Czech developer and is suitable for J2ME devices including a BlackBerry with OS 4.1 or greater.

Using offline maps with TrekBuddy enables you to download maps at detail levels that suit you, that load quickly as they are stored on the SD Card, and of course do not incur any data download costs, this is especially useful when you are roaming overseas. The map on the right is a screen shot from a Curve 8310, using a map created with the excellent gm2tb- GoogleMaps to TrekBuddy site.
How To

1. Download TrekBuddy: The ALX and COD files can be found via this link.

2. Install TrekBuddy: Use the BlackBerry Application Loader to install the application. Instructions on how to use application loader can be found here.

3. Set up the Folder System: Using Mass-Storage mode navigate to your SD Card using Windows Explorer, you need to create a folder called “data dir” with subdirectories called maps, resources, sounds, tracks-gpx, tracks-nmea, ui-profiles, wpts as shown on the diagram on the right.

Disconnect your BlackBerry from your PC and load the TrekBuddy application. Press the BlackBerry key to bring up the menu.

Go to Menu->Basic->Data Dir

This needs to be set to the location of the data directory you created, mine is

file:///SDCard/blackberry/data dir/

ensuring the slashes and capitalisation are correct. Next go to

Menu->Location-> GPS provider

for a BlackBerry such as the 8310 you should set it to internal GPS. If you have an external GPS puck it can be set up here.

5. Test GPS Connection: To test the GPS connection on menu, go to Start to enable GPS and then press the # key to bring up compass mode. Once you have a signal you should have a compass display with your current location like this. The green dot shows that you have a GPS signal.

6. Download a Map:As standard no maps are supplied with TrekBuddy. The easiest way to download a map quickly is using the Google Maps to TrekBuddy website by AwokenMind. To use this website use Google Maps to find the area you want to create a map for, give it a name then click download. The tar file that you create should be placed in the maps directory of your BlackBerry.

6. Use your map!: Disconnect the USB cable, load TrekBuddy, Start the GPS, and select the map you have just added.

Potential Problems

Setting Application Permissions:I didn’t need to do this, but you may need to give TrekBuddy access to your SD card and access to your internal GPS Device. This is done on the BlackBerry by navigating to
Options->Security Options->Application Permissions->TrekBuddy->Edit Permissions->Set all to'Allow'

Setting the Path to Media Card: If your path is not correct you will get the following error:
Failed to start tracklog: file://wrong-path/ net.rim.device.api.io.file.FileIOException: File system error
This means you should carefully check your path to the SD Card

Connecting with USB: Always exit TrekBuddy before connecting the USB cable and entering Mass Storage Mode, otherwise TrekBuddy can crash and may require a battery pull.

Further Information

• TrekBuddy is not a route-planning application for calculating a route form A to B. There are better applications around if you wish to achieve this, for an application which has can continue to function in voice mode despite data connection loss try AmAze.
• To create large atlas files I recommend the excellent GoogLeak application which can be found here. This enables you to download Terrain, Hybrid and Street Map style Google Maps, and store them at various resolutions in the atlas format.
• Open Source Street Maps are available, such as OpenStreetMap, a utility to create TrekBuddy maps using this database can be found here.
• Official TrekBuddy Wiki
• Official TrekBuddy Forums
• TrekBuddy creates .gpx files which can easily be plotted on to Google Maps in elevation and 2D using a utility such as GPS Visualiser.
• A CMS theme for the Curve’s 320*240 designed by Trispark can be found here.
