Configuration properties

jbpm.byte.block.size: File attachments and binary variables are stored in the database. Not as blobs, but as a list of fixed sized binary objects. This is done to improve portability amongst different databases and improve overall embeddability of jBPM. This parameter controls the size of the fixed length chunks.

jbpm.task.instance.factory: To customize the way that task instances are created, specify a fully qualified class name in this property. This might be necessary when you want to customize the TaskInstance bean and add new properties to it. See also the section called “Customizing task instances” The specified class should implement org.jbpm.taskmgmt.TaskInstanceFactory.

jbpm.variable.resolver: To customize the way that jBPM will look for the first term in JSF-like expressions.
