[wildfly-dev] Need write to standalone.xml after parsing

The Keycloak server is currently configured via a keycloak-server.json file. We are converting this to configuration through standalone.xml/domain.xml. To automatically upgrade, I need to read keycloak-server.json and write back to standalone.xml. I can easily add the operations to do this at parse time. The parser has this method: @Override public void readElement(final XMLExtendedStreamReader reader, final List<ModelNode> list) throws XMLStreamException So one way to do this is to parse keycloak-server.json at this time and add operations to the list. That puts everything into the management model. But nothing will be written to standalone.xml unless someone manually does a write operation from CLI. So my question is, what is the best way to accomplish this? Is there a good, safe way to manually trigger a flush to standalone.xml at this point or at some later point during startup? Stan
