Well, if you look at the original examples code, these two lines are the key
I think;
HSSFObjectData obj : workbook.getAllEmbeddedObjects()
which is actually a shorter way of saying this;
HSSFObjectData[] objs - workbook.getAllEmbeddedObjects();
for(HSSFObjectData obj : objs) {
...
}
That retrieves all of the embedded onjects as instances of the
HSSFObjectData class.
Then this line
byte[] objectData = obj.getObjectData();
allows you to get at the data of each embeded object. At it's most basic,
all I thin you need to so is this;
1. Get the ambedded objects
2. Look at their data and so
HSSFObjectData[] objs - workbook.getAllEmbeddedObjects();
for(HSSFObjectData obj : objs) {
byte[] objectData = obj.getObjectData();
byte firstByte = objectData[0];
}
You do not need any of the other code IMO - unless you are doing something
more involved. Give those four lines a try and see what happens.

If I do that, the only objects I get are:
Paint.Picture
Packager Shell Object
The length of the byte[] getObjectData returns is 0.
If I iterate over the entires in the Packager Shell Object (which is the
object containing the embedded exe), I get the following children (The
last number is object size via DocumentEntry.getSize():
Packager Shell Object.CompObj 76
Packager Shell Object.Ole10Native 180012 <--- these are the bytes I
want, the Ole10Native entry is not contained in the output from
workbook.getAllEmbeddedObjects()
