Posted on 2003-11-30
Last Modified: 2013-11-23
Hi, This should be a simple answer for anyone familiar with manifests for executable jar files. I'm trying to change the icon by declaring the icon to be used in the icon attribute of the manifest. I know that this attribute exists but I don't no the proper format of the attribute or how to include it in my manifest file.

So far this is what I am using in my manifest:

Manifest-Version: 1.0
Main-Class: exam.PER_0

Thanks for any help you can provide

I'm not aware of one, can you point to some doco that specifies it?

You can't just add this to the manifest, it needs to be in the .jad file too.

The icon should appear in the /res directory of the project (under ...wtk2.0/apps/yourapp/).  Normally, I create a further directory under /res called /images (or /icons).  In this case, the MIDlet-Icon should be set to /images/myicon.png.

Finally, don't forget to include the reference to the icon as the second parameter of the MIDlet-1 attribute (which contains MIDlet name, MIDlet icon, MIDlet class).

Should have mentioned that, thought specifying an image without including an image would be obviously a bit silly :)

Ah.  Good point objects, but not quite what I meant ;-)

You are absolutely right, the image itself also has to be included (as you say ;-)), but I meant that the MIDlet-Icon attribute needs to be specified in both the manifest and the .jad because the two files should contain the same information to ensure the integrity of the download :-)
