Where is BusinessObjects Enterprise Java SDK jars located(BO XI3.1)?

Question

We need to import Business Objects Enterprise Java SDK's jar files. However, there is no document or forum post that have the directory for version BOXI3.1.
By searching for the cecore.jar file, we find a directory that contains many Business Objects Enterprise Java SDK jar files:
D:\Business Objects\BusinessObjects Enterprise 12.0\warfiles\WebApps\BusinessProcessBI\WEB-INF\lib
Is this the correct directory for the Business Object Enterprise jar files?
We imported bellow SDK jar files:
asn1.jar
cecore.jar
celib.jar
ceplugins_client.jar
ceplugins_core.jar
ceplugins_cr.jar
cereports.jar
certj.jar
cesession.jar
ceutils.jar
clientplugins.jar
commons-codec-1.3.jar
commons-logging-1.1.jar
corbaidl.jar
ebus405.jar
flash.jar
freessl201.jar
jsafe.jar
logging.jar
pluginhelper.jar
postprocessing_oca2service.jar
publishing_oca2service.jar
rasapp.jar
rascore.jar
reporttemplate.jar
serialization.jar
SL_plugins.jar
webreporting.jar
xbean.jar
xcelsius.jar
XcelsiusSLPlugins.jar
Is this the complete list that we should import for X3.1? there are some files like commons-codec-1.3.jar, it looks a Apache jar file, not the SDK's jar file. shall i include such files as well?

Don't know why I see this error when I am creating the SessionMgr object even though I have the CrystalDecisions.Enterprise.Framework and CrystalDecisions.Enterprise.InfoStore referenced:
SessionMgr sessionMgr = new SessionMgr();
