Difference between plugins
Jive 6
In Jive 6 the pluging uses JAXWS with Spring to create a REST Service from which the connector can retrieve the security group ACLs for each space, group and blog.
Jive 7.0.0.X
In Jive 7.0.0.X due an update from Apache the REST functionality was moved to a new library called JAXRS, which required the update of the plugin. The service code changed a bit, but the logic path and output stayed the same.
Jive 7.0.X.X
For Jive 7.0.X.X the host location of the REST Service was to be indicated. So to keep the same path as the previous versions, the REST Service is hosted in the bus rpcCxfBus. The logic, path and output remained the same.
