  • I am trying to execute the sample jBPM5 Human Task sample that comes with JBDS 5.x . I am trying to use it with the in-memory database (Hypersonic) for the persistence. However, the following lines from shows below errors while I am working on the workspace.


The method startH2Server() from the type JBPMHelper refers to the missing type Server
The method setupDataSource() from the type JBPMHelper refers to the missing type PoolingDataSource

Can you please guide me what am I missing and also guide me how to set-up the example properly?
