jbpm_log description/ query for information

[x490812]

I would like to be able to find the path of execution for a process instance by reading the jbpm_log table. in addition, for each entry, I want to know the processinstance, taskinstance, process node, variable names and values. Is there a field definition listing for this table someplace so that I could create a query? I noticed in the jbpm3.1 datamodel that jbpm_log.class_ is Bool, yet in my schema it is char(1). I would particularly like to know what class_ relates to, as I see I, R, U, T, A, X, Z, N, S values in that column, but dont know what they are or relate to. Is there some easy way to get the information listed above in a query so I can validate / unit test the application.

the class column is for using one table for multiple (inherited) classes in hibernate. See the hibernate config files what classes they relate to
