Petals ESB Container

We want to use the Petals SE Activiti with the Activiti database managed by a PostgreSQL server:

• The Petals SE Activiti is configured to use a shared library embedding the JDBC driver for PostgreSQL,
• When installing Petals SE Activiti with Petals CLI, we get the following error:

  ....> petals-cli -h localhost -n 7700 -u petals -p petals -c -- deploy -s -u file:///tmp/petals-se-activiti.zip -D jdbcUrl=jdbc:postgresql://172.17.0.38:5432/activiti,jdbcDriver=org.postgresql.Driver,jdbcUsername=petalsseactiviti,jdbcPassword=PetalsSeActiviti
  ERROR on command 'deploy': org.ow2.petals.admin.api.exception.ArtifactAdministrationException: org.ow2.petals.jmx.api.api.exception.AttributeErrorException: javax.management.InvalidAttributeValueException: Invalid value for attribute 'jdbcDriver': The class 'org.postgresql.Driver' has not been found.
