This application is not compatible with your device and cannot be loaded

Question

Hi,
I have been trying to load an application to my BB 9000 since a monday and getting this error "This application is not compatible with your device and cannot be loaded".
As evident, I am new to BlackBerry development and got to port an existing J2ME project on BB 9000.
To load application I am using  
- BB Dektop software 5 (latest)
- BB Device Software 4.6 is installed (which is the version of BB 9000 as well)
I am able to load sample JDE 4.6 applications but I build my project through same JDE and through eclipse (JDE compoment 4.6.0.19) as well but couldn't load it,
I even signed my app since I am using net.rim.device.api.servicebook api which requries signing.
Can someone please explain me
1) why this error occurs in first place 
2) how to setup right envioroment to load an application on a given BB handset (BB 9000 vodafon India to be specific)
3) How would manage this process on a single machine if I have 4-5 different BB handsets.
I shall be thanful for any logical pointer to solution to these problems.

Hi,
The main problem with your genrated ALX file. I think in your ALX file contains <fileset Java="1.49" _blackberryVersion="[5.0.0)"> TAG  and remove the  _blackberryVersion attribute. Then it will work.
So your final ALX file contains
<loader version="1.0">
    <application id="App">
        <name >
            App1
        </name>
        <description >
        </description>
        <version >
            1.0.0
        </version>
        <vendor >
            Vim
        </vendor>

        <fileset Java="1.49">
            <directory >
                5.0.0
            </directory>
            <files >
                App.cod
            </files>
        </fileset>
    </application>
</loader>
Even thought it is not installed then make sure that your application may not delete from your device. Select the application and click on delete button in Desktop manager.
Still u didnt slove the problem  then insted of
 <directory >
                5.0.0
    </directory>
replace as
 <directory >
  </directory>
