WEB Services JAX-RS

I have folleowed the instructions for deploying a simple web service to Liferay portal:


https://dev.liferay.com/de/develop/tutorials/-/knowledge_base/7-1/jax-rs

As written there, I have created an OSGi Module using an Maven REST Archetype.

I have depooyed it to Liferay Community Edition Portal 7.1.2 CE GA3.


I am ablo to obtain the access_token from Liefray, but when I want to call the service with curl (on a localhost - exactly like in the tutorial), than there is no response (see attacheed iamge).

When starting on something new, you should start with the easiest scenario and then move to more complex thing.

I would first test your service after disabling authentication.

This can be acheived with following code as the header of your main REST application

@Component(
    property = {
        JaxrsWhiteboardConstants.JAX_RS_APPLICATION_BASE + "=/yourpath",
        JaxrsWhiteboardConstants.JAX_RS_NAME + "=Your.Application.NAME",
        "liferay.auth.verifier=[b]false[/b]",
        "liferay.oauth2=[b]false[/b]",
    },
    service = Application.class
)
public class YourRestApplication extends Application {
...
}
Then try again your curl command.

Helllo, thanks for your support.

I have finally got the example from Liferay Site to work. I have had to add following line to the JAX-RSn Application Class:

"oauth2.scopechecker.type=none"


@Component(
     property = { 
          JaxrsWhiteboardConstants.JAX_RS_APPLICATION_BASE + "=/greetings",
          JaxrsWhiteboardConstants.JAX_RS_NAME + "=Greetings.Rest",
          "oauth2.scopechecker.type=none"
     }, 
     service = Application.class
)
public class MyRestApplication extends Application {
...
}
