---

loadProcessDefinition

public ProcessDefinition loadProcessDefinition(long processDefinitionId)

loads a process definition from the database by the identifier.

Throws:

a - JbpmException in case the referenced process definition doesn't exist.

---

getProcessDefinition

public ProcessDefinition getProcessDefinition(long processDefinitionId)

gets a process definition from the database by the identifier.

Returns:

the referenced process definition or null in case it doesn't exist.

---

findProcessDefinition

public ProcessDefinition findProcessDefinition(java.lang.String name,
                                               int version)

queries the database for a process definition with the given name and version.

---

findLatestProcessDefinition
