-To compile this project, you will need to use a special Java compiler.
-If you are using SDKMan!, then the version will be correctly selected for you.
-Or, you can do the following:
+After running this sample like so:
 
-```bash
-sdk use java 23.0.5.r17-nik
-```
-
-After that, you can compile like so:
-
-```bash
-./gradlew nativeCompile
-```
-
-Once compiled, you can run like so:
-
-```bash
-./build/native/nativeCompile/data
-```
+.Java
+[source,java,role="primary"]
+----
+./gradlew :bootRun
+----
 
 Then you can query for messages using `luke/password` and `rob/password`.
 
-Because the domain objects are secured, you will see a subset of fields with `luke`.
+Because the domain objects are secured by ACLs, Rob will only see Rob's messages, and Luke will only see Luke's.
 
 For example, querying `/` with `luke`, you'll see:
 
-```json
-  ...
+[source,json]
+----
+[
     {
-        "created": "2014-07-12T16:00:00Z",
-        "id": 112,
-        "summary": "Is this secure?",
+        "created": "2014-07-12T10:00:00Z",
+        "id": 110,
+        "summary": "Hello Luke",
         "text": "This message is for Luke",
-        "to": {
-            "email": "[email protected]",
-            "id": "luke",
-            "password": "password"
-        }
-    }
-  ...
-```
-
-However, with `rob`, you'll also see `firstName` and `lastName` like so:
-
-```json
-  ...
+        "to": "luke"
+    },
+    {
+        "created": "2014-07-12T10:00:00Z",
+        "id": 111,
+        "summary": "Greetings Luke",
+        "text": "This message is for Luke",
+        "to": "luke"
+    },
     {
-        "created": "2014-07-12T04:00:00Z",
-        "id": 102,
+        "created": "2014-07-12T10:00:00Z",
+        "id": 112,
         "summary": "Is this secure?",
-        "text": "This message is for Rob",
-        "to": {
-            "email": "[email protected]",
-            "firstName": "Rob",
-            "id": "rob",
-            "lastName": "Winch",
-            "password": "password"
-        }
+        "text": "This message is for Luke",
+        "to": "luke"
     }
-  ...
-```
-
-You can also change the message text.
-To do this, copy and paste the `X-CSRF-TOKEN` and `Cookie: JSESSION` headers and include them in a `PUT :8080/102` request.
-
-An example of this request using HTTPie can be seen below:
+]
+----
 
-```bash
-echo -n "updated message" | http -a rob:password PUT :8080/102 "X-CSRF-TOKEN: {copied from GET request}" "Cookie: JSESSIONID={copied from GET request}"
-```
