Hi guys, after many steps finally i got my first app ready but it was rejected by the app world because it wasn't signed.

I've installed new keys to sign my app, so then when i try to debug my app in the simulator it marked that error

I've been searching and didn't find an answer, my app worked without the sign and now it fails

Note: I'm using ksoap jar verified in my app as a external jar.

Knowing which class was not found would help immensely.

Thanks for your help.

There's no message  indicated in the error.  Please see the picture below.

Instead of using jar file better to user src file. You will the source may be @ http://sourceforge.net/  (not sure)

[aperezdev]

It's my very first app, I don't know how to do it, I'm afraid that if i change the src my parse will not work again

[kamal_nigam]

It won’t affect your code. You have .classes file in the jar file. Better to go with source files

Let us start back at the beginning.

Signing an app does NOT cause it suddenly to not find classes.  There is something else going on here.

Can you recreate your unsigned app and does it work?  I suspect not.

Continuing a little, you have not answered RexDoug's question regarding which file was not found.  If you run this in the Simulator I think the log will tell you this.  So run it again and see.  That will determine the appropriate action.

You seem to have decided it is something to do with kSoap.  If you have included the kSoap jar file correctly in your application, then it will be included in your cods OK.  Adding the kSoap source and compiling it yourself should not be needed.  It won't hurt, but it shouldn't be needed.

Thanks to all for responding and helping. I have the Console messages and i found something that the string builder class is not defined...but i'm not using it directly, these are the messages:

StringBuilder is not available on BlackBerry. 

Other pwople have had this problem, if you search the forum you will probably find your answer.

For example I found this:

I understand but, as i mentioned my app worked fine until i put the new keys, that's strange because i have the screenshots and the previous .cod files that i'v tried to publish to the bb app world. That's strange so there's another thing that it's crashing my app?
