Create lcmbiar from java sdk - few questions

Hi!

I'm trying to make a .lcmbiar file for many of my BI objects (Webi, Universes, Connections without dependencies) - one .lcmbiar for one object. For now I do it in LCM command line tool, but it's not good, because it create job in CMC for each object and it takes time (it login to CMC for each execute). My questions are:

1. I need to create .lcmbiar without creating job in Promote Manager. How to do it?

2. It takes time to execute command for one objects (aspecially logging to SAP BO). Can I just one login, create biars (one biar for one object) and logout?

3. I see there is a lcm.jar, but it's only on server side (I don't see it when I install only client tools). Which jar's shoud I include? There is a 1.4 GB jars in \SAP BusinessObjects Enterprise XI 4.0\java\lib\ folder and I think, that lcm don't need all...

4. There is a biarengine.jar, that create .biar file. Can I use this .biar's to import object in Promote Manager? What is a diffrence with .biar and .lcmbiar?

SAP BO 4.1 SP3

Thanks!
