we get the following Warning for a new BPM 12c installation. How can we correct configuration to solve this issue?
<Warning> <J2EE> <...> <soa_server1> ...<<WLS Kernel>> <> ... <BEA-160140> <Unresolved optional package references (in META-INF/MANIFEST.MF): [Extension-Name: custom.client.applib, Specification-Version: 1, Implementation-Version: 1.0, referenced from: .../Oracle_Home/user_projects/domains/base_domain/servers/soa_server1/tmp/_WL_user/OracleBPMWorkspace/jx2oeu/war]. Ensure that the referenced optional package has been deployed as a library.>
custom.client.applib is extension name of Jar for Workspace Customization.
Have you done the same in your environment?
