May I publish Symbian package containing more than one executable

It is not clear for me from the publisher's guide is it possible to publish Symbian package (.sisx) which contains more than one executable file.
I have an application which is split in separate parts (executables): Server, Gui settings, Widget...
So I creating a single package which have the UID like one of that executables.
Can I publish such package to the Nokia Store?

Sure you can have multiple executables.

also you can embed sis files into sis file, as well as you can add sis files as content (for installing later from the applciatoin) into sis file. Anyway do remember that each sis file need to be signed.

Thanks.
So it doesn't matter from what of my executables I'll take the UID for the whole package?

generally speaking the package UID could be any of the UIDs used with the executables, or even different one, as far as it is globally unique. Do note though that if you are using auto start feature, then the package UID must be the same as is used with the autostarted executable.

If publish this package to the Nokia Store, is there some limiting condition?

Do you have any specific doubts? Your application must follow some guidelines available on publisher website.

Yep, without actually specifying on what the issue you are worried is about, we can not really go guessing it..
