A year or so ago I wrote out some instructions detailing how to make SignatureTool.jar work in Unix type systems. Soon after I got word that somewhere around JDE 4.6 or JDE 4.7, RIM actually fixed the mistake in the sigtool. Sadly they missed one.
If you attempt to sign a .cod file larger than 64KB (ie: contains sibling files or child files or whatever files) then you will likely get a file created in your current working directory that looks something like kd8m34jkf/my_lame_app-1.cod. When you load the file to the device it will result in an error of some sort. The fix for this is relatively simple. Read on for the details.
Edit class file
Go back and read my other post for instructions on extracting the jar file and for packaging it up again. I’m going to leave out some details here since they are covered previously.
Note: this is based on the SignatureTool.jar file from JDE 4.7. I have not verified that this procedure is the same for other versions of the JDE.
We will use good old ClassEditor again. Open q.class and change string constant at index 253 from a back slash to a forward slash.
