BusinessObjects Web Services Consumer jar files

Hi,

i'd like to build a Java consumer for BusinessObjects Web Service.

I read in the doc that I need to add to my project the Java consumer JAR files located in C:\Program Files (x86)\SAPBusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib.

The problem is that there are about 400MB of jars so my question is: What are the web services consumer jars that can I extract form that folder and include and distribute in my application?

I use SAP BO 4.1
