Java-play2 - Application cannot determine route path

[fehguy]

howdy, I followed these steps and was able to run the sample just fine--I'm putting in tests today to make sure it stays healthy. Can you please confirm you've followed these steps and still see that error?

• publish modules/swagger-play2-utils locally via "play publish-local" in that folder
• publish modules/swagger-play2 locally via "play publish-local"
• run the sample app with "play clean" then "play run"

You should be able to hit http://localhost:9000/resources.json and get this:

{
  "apiVersion":"0.1",
  "swaggerVersion":"1.0",
  "basePath":"http://localhost:9000",
  "apis":[
    {
      "path":"/user.{format}",
      "description":"Operations about user"
    },
    {
      "path":"/pet.{format}",
      "description":"Operations about pets"
    },
    {
      "path":"/store.{format}",
      "description":"Operations about store"
    }
  ]
}

and http://localhost:9000/pet.json

should produce something like this:

{
  "apiVersion":"0.1",
  "swaggerVersion":"1.0",
  "basePath":"http://localhost:9000",
  "resourcePath":"/pet",
  "apis":[
    {
      "path":"/pet",
      "description":"Operations about pets",
      "operations":[
        {
          "httpMethod":"POST",
          "summary":"Add a new pet to the store",
          "responseClass":"ok",
          "nickname":"addPet",
          "parameters":[

...

I tried a clean setup - new play 2.0.1, swagger-core-91670c5.

Followed you steps.

• publish modules/swagger-play2-utils locally via "play publish-local" in that folder
• publish modules/swagger-play2 locally via "play publish-local"
• run the sample app with "play clean" then "play run"

Since swagger-play2-utils have swagger-play2 dependency, there was an error. so changed the order.

• publish modules/swagger-play2 locally via "play publish-local"
• publish modules/swagger-play2-utils locally via "play publish-local" in that folder
• run the sample app with "play clean" then "play run"

Setup and publishing was smooth.

The response for resources.json and pet.json reflects the same as referenced in your message.

But, the error still persists.

Hi

Any update on this issue. I'm still having this error, which i do not see in the scala version sample. Kindly update.

EDIT : More information on my Environment : Windows 7 and Jdk 1.7.0_03 / And also on Linux with jdk 1.7

[fehguy]

Hi, all testing has been done on JDK 1.6. Is there a chance you can try that version so we can hunt down the issue?

I also just updated the Build.scala to point to a github-hosted ivy repo so you don't need to build the swagger-play2 project or the swagger-play2-utils. Could you please pull and try again?

[brainwatch]

Hi

I tried all scenario

• with jdk 1.7 and latest java-play2
• with jdk 1.6 and latest java-play2

but still the error persists. One thing I notice is that the error persists, but its not following the same sequence. I'm attaching the the trace again fyr. And once the first time url is called, it hangs and no more calls are services by the server.

I would appreciate your help in resolving this.

EDIT : Tried scala version and its just smooth and also reflected in the ui perfectly.

[fehguy]

well good news and bad news. I fired up a fresh VM with windows XP (yes, I know that's old) but with play 2.0.1, jdk 1.6.0_27 and a fresh clone of swagger-core. I had to make 2 changes for windows to work with the Build.scala (I'm committing those) but both the swagger-play2 sample and java-play2 sample run just fine. I think I'll need to chat with you on IRC #swagger to figure out why it's failing for you. It's really weird.

What time zone are you in? If you can ping me at tonytam on irc then I'd be happy to help sort this out.

[brainwatch]

Hi

Good and a Bad news from my side too. I tried you patch on jdk 1.6. The error still exists but the system works fine ( except the swagger UI ) and I was able to fire queries on each service uri multiple times. The system did not hang on the first call like before. But on jdk 1.7, the error exists and the system hung on first call to the uri itself.

I'm on GMT + 5:30 ( India ) timezone. Let me know your availability on IRC and I'll ping you.

Thank you for your time.

[angeloh]

I also got the same errors. I am not sure what I do wrong. All swagger jsons return normally.

[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.Register.registerByForm()

[angeloh]

I just tried the java-play2 sample project. Yes, I got same error too.

[debug] application - /user
[error] application - Could not find route controllers.UserApiController.updateUser
[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.UserApiController.createUsersWithListInput()

[fehguy]

Hi, I think that error message is a red herring. We'll get the message sorted out and report back exactly why it's there.

[brainwatch]

Hi

Also the service call to particular action ( example : /pet.json/1 ... 10 ) is returning a json with all null data. I think either the data is not loading due to the error which we are talking about or the service query is not able to fetch the data.

[fehguy]

I've confirmed the issue, only happens in the java play2 sample. Looking into it...

[fehguy]

There was test code in the java app that should have been removed :( It's gone now, and the sample is returning the correct data now.

[angeloh]

Thanks. Btw, could you paste the solution or link here?

[angeloh]

I tried java-play2. Here are the errors when browse http://localhost:9000/user.json.

[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.UserApiController.createUser()
[debug] application - /user
[error] application - Could not find route controllers.UserApiController.createUser
[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.UserApiController.createUsersWithArrayInput()

[ayush]

@brainwatch @angelokh @fehguy there was a bug in the play2 plugin which was causing this to happen only for java. This has been fixed now.

[angeloh]

Still have errors in java-play2.

[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.UserApiController.updateUser(java.lang.String)
[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.PetApiController.addPet()
[error] application - Cannot determine Path. Nothing defined in play routes file for api method public static play.mvc.Result controllers.StoreApiController.placeOrder()
[debug] application - /user
[debug] application - /pet
[debug] application - /store
[error] application - Could not find route controllers.PetApiController.addPet
[error] application - Could not find route controllers.StoreApiController.placeOrder
[error] application - Could not find route controllers.UserApiController.updateUser

[ayush]

Did you

1. Get the latest swagger-play2 module
2. Publish it locally (play publish-local)
3. Rebuild the app (play clean, play start)

?

[angeloh]

I follow your steps, still get same errors.

Then I remove /usr/local/share/play-2.0.1/framework/../repository/local/com.wordnik/swagger-play2_2.9.1/1.1-SNAPSHOT/ and do a local-publish again. And clean and run java-play2. The errors are still there.

Another problem I found in java-play2 and swagger-play2. Both were looking for commons-io jar. So I have to add "commons-io" % "commons-io" % "2.3" to Build.scala to be able to build them.

[warn] [NOT FOUND ] commons-io#commons-io;2.0.1!commons-io.jar (0ms)

[angeloh]

This is my current local repo status.

$ git pull
Already up-to-date.

$ git log --oneline
9f7acc6 fixed the path param name for getPet
d615dfb Bugfix to support discovery of java controllers in PlayApiReader

[angeloh]

I guess this is the problem. The current sample https://github.com/wordnik/swagger-core/tree/master/samples/java-play2 is using jars from github repo.

[fehguy]

@angelokh you can either publish locally or use the pre-compiled versions in the github repo. If you build locally, I'd recommend wiping your ivy cache, at least the com.wordnik artifacts.

[brainwatch]

It works fine.

[angeloh]

Okay. If I browse http://localhost:9000/resources.json, it works fine. However, when I use it w/ swagger-ui, bunch of errors pop up. I will open another ticket.
