WSO2 bps 3.0.0 how install DSS feature

How can I install DSS feature to wso2 bps 3.0.0? I try with Feature Management using http://dist.wso2.org/p2/carbon/releases/4.0.1/

I get this error :

Caused by: java.lang.Exception: HttpSession is null

        at org.wso2.carbon.feature.mgt.stub.ProvisioningAdminServiceStub$3.onFault(ProvisioningAdminServiceStub.java:991)

Could someone please provide more information on how this could be done?

Solution

BPS 3.0.0 and DSS 3.0.0 is not yet released. It will be released in the next few days.
