jad and jar size do not match in j2me

Question

I am using N97 and Nokia 5530 for my application. More often whenever I install my application. I find this error. I have searched the internet and found a number of ways to solve this problem. I did use them such as check size of jar and the one written in jad and corrected it but still problem is not solved.

How can I remove this error in my build. Any help in this regard is highly appreciated.

I have read the stuff--- Unification of .jar and .jad files in a J2ME application --- but today devices and internet are much faster. Can't we ignore the creation of jad file.

EDIT

Following are jad and manifest attributes. I am using NetBeans 6.9 and Nokia S60 5th Edition SDK to generate and build the MIDlet.

jad attributes are as follows

Backkey: -11
LGE-MIDlet-Height: 400
LGE-MIDlet-Target-LCD-Height: 400
LGE-MIDlet-Target-LCD-Width: 240
LGE-MIDlet-Width: 240
LeftSoftKey: -6
MIDlet-1: MyAppName,/icon.png,com.main.MainMidlet
MIDlet-Jar-Size: 964642
MIDlet-Jar-URL: MyAppName.jar
MIDlet-Name: MyAppName
MIDlet-Permissions: javax.microedition.io.Connector.http

The only thing I can think of is that I usually see MIDlet-Jar-Size in the manifest, not in the jad.

Unfortunately, I never figured out how the build system managed to insert it in a compressed file (jars are basically zip files) and I don't know how to tell Netbeans to move the property from the jad to the manifest.

I was under the impression that if you ask Netbeans to generate a simple HelloWorld MIDlet and don't modify the ant script, MIDlet-Jar-Size ends up in the manifest.

I do think there is a relation between the property and the MIDlet being signed. It may act as a checksum.
