Hi,

These properties are automatically created and managed by JCR. In general, most nodes will automatically add or update these properties when there are changes to the node[1]. Since these are protected properties, it is not recommended to update them programmatically. If you need to track an updateInformationDate based on business requirements, the best approach is to create a custom property and update it as needed. However, if you still wish to update these properties directly, the following approach should work:

Node node = session.getNode(path)
node.setProperty("jcr:lastModified", Calendar.getInstance()); 
node.setProperty("jcr:lastModifiedBy", "esteban"); 
session.save();
