How do I access my REST builder application

I've built an application using REST builder using DeveloperStudio 3.9.7. It compiled and deployed to LR 7.4 (liferay-dxp-7.4.13.u36/) without any errors. It shows up in the gogo shell when I run "jaxrs:check" (see attached screen capture). My rest-openapi.yaml file is as follows:

But when I try http://localhost:8080/o/v1.0/dl-service/folders/43741 in my browser I get a 404 error.

So I'm trying to figure out what the correct URL is. Any help would be greatly appreciated.

I'm not familiar with building REST APIs, but for example, this is how I'd call a URL to a forms endpoint:

curl -X 'GET' 'http://localhost:8080/o/headless-form/v1.0/sites/20121/[SiteId]' -u '[me@liferay.com:myPass]'

Site Id, user name, and password will vary of course. It's not a great example because it's a deprecated API, but it gets the point across.

Your URL structure looks different, in that it's missing the baseURI after the /o/ (defined in a rest-config.yaml as I seein Liferay's src code and the documentation).

Thanks Russell. I hadn't seen that documentation before, it looks a bit more thorough than the one I found: https://help.liferay.com/hc/en-us/articles/360028748872-Generating-APIs-with-REST-Builder

I'll look through it, thanks again.

I do have the baseURI property, it's in a separate file, rest-config.yaml:

apiDir: "../dl-service-api/src/main/java"
apiPackagePath: "gov.nasa.hq.liferay.dlservice"
application:
baseURI: "/dl-service"
className: "DlServiceApplication"
name: "DlService"
author: "sweiss"
clientDir: "../dl-service-client/src/main/java"
testDir: "../dl-service-test/src/testIntegration/java"

So you'd use the baseURI value in your URL; in my example the baseURI was the headless-form part. But if your enpoint isn't showing up in the API explorer (probably also under a menu item named after the baseURI) there may be some other issue.

An easy way to find this kind of detail is to just use the API explorer at /o/api

It can show you how Liferay presents your RESTBuilder solution, plus you can even run some active tests...

My application doesn't seem to show up there. It does show up in the gogo shell though.

Use scr:list <bundle id> to list all of the OSGi component services in the bundle and ensure that all of the components are active.

If there are some that are not, use scr:info <service id> to see what problems they may have....

Here is the output from the impl bundle, all seem to be active:

If I run: scr:info DlService I get an error:

Error: Multiple components matching "DlService": [com.liferay.document.library.internal.upgrade.registry.DLServiceUpgradeStepRegistrator, gov.nasa.hq.liferay.dlservice.internal.resource.v1_0.FolderResourceImpl, gov.nasa.hq.liferay.dlservice.internal.resource.v1_0.OpenAPIResourceImpl, gov.nasa.hq.liferay.dlservice.internal.graphql.servlet.v1_0.ServletDataImpl, com.liferay.document.library.internal.verify.DLServiceVerifyProcess, gov.nasa.hq.liferay.dlservice.internal.jaxrs.application.DlServiceApplication, com.liferay.dynamic.data.lists.internal.upgrade.registry.DDLServiceUpgradeStepRegistrator, gov.nasa.hq.liferay.dlservice.internal.resource.v1_0.factory.FolderResourceFactoryImpl]

Could the problem be a name conflict?

It's probably worth a shot to test a quick refactor.
