Swagger integration with existing Apache Wink application

[Kapil Sharma]

I am following this tutorial to integrate existing apache wink restful web service with Swagger. I am getting below exception, not sure what could be the cause. Can someone point me to a good direction?

Are you sure the issue is related to Swagger? There's nothing in the logs indicating it.
Were you able to run the application before adding Swagger to it? If you didn't try, can you try removing Swagger and checking?

Thanks Ron, Yes, I am able to run the service before running the swagger.I did a further digging. The issue happens as soon as I add swagger annotations e.g. @Api(value = "servicename", description = "Operations to get the service Data") and @ApiOperation(value = "Find data by given criteria", notes = "This operation provides the  data in the json format as per the the provided criteria", response = MyResponse.class).

Assuming this is a maven-based project, can you attach the output of 'mvn dependency:tree'?

There's something weird going on here.

The exception you see is

Caused by: javax.xml.transform.TransformerFactoryConfigurationError: Provider for javax.xml.transform.TransformerFactory cannot be found

Which for the moment I can't see how it's related to Swagger (notice that there's no mention of Swagger in the log).

Based on http://www-01.ibm.com/support/docview.wss?uid=swg21661696 this could be some kind of a dependency issue which is why I asked for 'mvn dependency:tree' and not just the list of dependencies.
Something that's being pulled in (or not pulled in) can be the cause of it.

[Kapil Sharma]

Now, I deployed the same webservice to Tomact 7.0.55. The service seems to be fine, no error messages but when I invoke the URL I get the empty response.

I'm invoking the URL http://localhost:8080/service/rest/swagger/api-docs. 

The swagger base path has been set up to swaggerConfig.setBasePath("http://localhost:8080/service/rest/swagger");

my ApplicationConfig class has application path as @ApplicationPath("swagger")

Any help will be highly appreciated.

Hi Kapil,

If the same application works properly under Tomcat but not under WebSphere, then this is an issue with the WAS which unfortunately I won't be able to help with as I don't have access to it (being a commercial product),
It's possible there's an issue with classloading, and possibly the distribution of shared libraries. It's quite possible that swagger-core has nothing to do with it and adding it (much like possibly any other library) has triggered the change in classloading.

As for running it on tomcat, the swagger base path has nothing to do with where your api-docs are hosted. They'd be hosted directly under the path exposing your API.
In your case (based on the previously shared web.xml), it should be http://localhost:8080/service/rest/api-docs.

Please let me know if that works for you.

Hi Ron,

I appreciate your help very much. What I meant was in Tomcat I didn't find any startup error logs when I deployed the application in tomcat. After struggling thru the configurations, I finally got it somewhat working in tomcat (I am not using websphere anymore). But the /api-docs returns only partial response. Which is shown below

{"apiVersion":"1.0","swaggerVersion":"1.2","apis":[{"path":"/listings","description":"The API lists all the operations related to search"}],"info":{"title":"Search Service","description":"This is search service app.","contact":"xx...@xxx.com","license":"Apache 2.0 License","licenseUrl":"http://www.apache.org/licenses/LICENSE-2.0.html"}}

So it shows what I provided at the Resource level but  (@ApiOperation) is not being picked. I think I am missing a very small setting. Below a sample code of my resource class:

@Path("listings")

@Api(value = "modelListings", description = "The API lists all the operations related to search")

public class ModelListingsResource {
 
@GET
 @Path("list/{pathparam1}/{pathparam2}/json")
 @Produces(MediaType.APPLICATION_JSON)
 @ApiOperation(httpMethod = "GET", value = "Find listings by given criteria", notes = "This operation provides the listing data in the json format as per the the provided criteria", response = Result.class, nickname="list/{param1}/{param2}/json")
 public Result getJSONListings(
 @ApiParam(value = "Path parameter for the 1st category ", required = true) @PathParam(param1) String param1,
 @ApiParam(value = "Path parameter for the 2nd category, required = true) @PathParam("param2") String param2,
 @ApiParam(value = "query parameter for the primary sort field", required = false)  @QueryParam("sf1")  String sf1) {
 return new Result();
 }


}

My web.xml looks something like this:

<servlet>
 <servlet-name>restService</servlet-name>

 <servlet-class>org.apache.wink.server.internal.servlet.RestServlet</servlet-class>
 <load-on-startup>0</load-on-startup>

Actually, that looks fine.

Try adding "/listing" after your "/api-docs".

For example, if you browse to http://localhost:8080/myapp/api-docs, then instead go to http://localhost:8080/myapp/api-docs/listing

If you look at the output of /api-docs, you'll see an "apis" property which lists the resources available. In your case, it mentions "/listing".

Hi Ron,

Yes, you are right. It works fine. I hope the setup which I have mentioned above, helps rest of the folks who are trying to set up swagger with Wink.

Glad to hear it all works out for you.
If you have any further questions, feel free to ask.

Do you know if it is possible to set up swagger with jax rs without the use of Maven? I have tried to set it up this way but I am getting a 405 when I try to hit my path. Im testing this out on a websphere process server 7.0. When I hit my basepath I get "can't read swagger JSON unable to load swaggerUI". Can you help with this?

Thanks

Hi Ron,

[Ron]

Of course it's possible, it just requires more manual work. Which JAX RS implementation do you use?

We do not use Maven, hence wanted a list of jars which we will need for this integration.

Hi there,

I have created a simple maven project that integrates Apache Wink with Swagger. It is available below

https://github.com/zouzias/swagger-jaxrs-wink.git

Cheers
Anastasios

[tony tam]

Great!  Do you want to add this to swagger-core develop_scala-2.10 branch and send a pull request?  I'm sure others would like to have this in the core samples.

[Anastasios Zouzias]

Sure, I would love to do that.

I put it under develop_scala-2.10 if there is no develop_java-2.10 branch.

Thanks, I’ll use that as a baseline and update it to the petstore project.

Hi Tony,

I had to understand better the integration with JAXB, so I integrated the petstore project as well. I tested a few cases and it seems OK to me.

You can use this as a baseline:

https://github.com/zouzias/swagger-jaxrs-wink

PS. Not sure if I configured correctly Jackson's JAXB annotations.

Best,
