Try to write jar -cfvm E:\j2me\midlets\HelloWorld.jar manifest.txt -c instead of jar -cfvm E:j2me\midlets\HelloWorld.jar manifest.txt -c. Notice the added \. E:\... instead of E:...

Hi friend,
This work fine when i put '\' after E:.It also creates the jar file.And u also have give the path after -c which specifies where exactly class file lies.

The command is,

jar -cfvm E:\j2me\midlets\HelloWorld.jar manifest.txt -c E:\j2me\classes\greeting


It is creating .jar file in midlets folder.
By extracting it i get 2 folders,
1)midlets\HelloWorld\j2me\classes\greeting
which contains class file and .png image

2)\midlets\HelloWorld\META-INF
which contains the manifest file

But while excuting the above command it gives follwing error


E:\j2me\src\greeting>jar -cfvm E:\j2me\midlets\HelloWorld.jar manifest.txt -c E:\j2me\classes\greeting
-c : no such file or directory
added manifest
adding: E:/j2me/classes/greeting/(in = 0) (out= 0)(stored 0%)
adding: E:/j2me/classes/greeting/HelloWorld.class(in = 1554) (out= 710)(deflated 54%)
adding: E:/j2me/classes/greeting/logo.png(in = 295) (out= 295)(deflated 0%)

E:\j2me\src\greeting>

Note:
contains of manifest.txt

MIDlet-Name: Hello World
MIDlet-Version: 1.0
MIDlet-Vendor:
MIDlet-1: HelloWorld,/greeting/logo.png,greeting.HelloWorld
MicroEdition-Configuration: CLDC-1.0
MicroEdition-Profile: MIDP-1.0


Does anyone know Whats the coz for this error?
which file it doesn't get while jaring as you see that
it first added the manifest file
then while adding it shows (in = 0) (out= 0)(stored 0%) what is exactly it is looking for?
then added class file
and in the last the .png file

How could i resolved this problem?
What i've include/remove while creating .jar file?

When i run the midlet using follwing command

midp -classpath HelloWorld.jar -Xdescriptor HelloWorld.jad
It throwing class not found exception.

This is might be coz in .jar file the class file is stored in
midlets\HelloWorld\j2me\classes\greeting
which should stored in
midlets\HelloWorld\greeting

When i change the command for creating .jar it is not added the class file and image which stored in E:\j2me\classes\greeting dir.

Note:
contains of .jad file

MIDlet-Name: Hello World
MIDlet-Version: 1.0
MIDlet-Vendor:
MIDlet-Description: My First MIDlet suite
MIDlet-1: HelloWorld, /greeting/logo.png ,greeting.HelloWorld
MIDlet-Jar-URL: HellowWorld.jar
MIDlet-Jar-Size: 1901

How could i resolved both this issues?
