Getting error 404 in deployed swagger project

[Ivan Sousa]

Hello, I'm new to developing REST Web Services and Swagger. I'm using JAX-RS/Jersey and Eclipse and I already managed to configure and deploy the project into the server(JBoss) but when I go to http://127.0.0.1:8080/PROJECT i get this:

When I press the ERROR this shows up: {"schemaValidationMessages":[{"level":"error","message":"Can't read from file http://127.0.0.1:8080/PROJECT/swaggerUI/swagger.json"}]}

And when I press "try this operation" I always get a error 404, i know i didn't change anything in the impl dir but it should give me the default response, or shouldn't?

Appreciate any help.

For the validation error – which version of swagger-ui do you use?

For the 404, it’s likely you didn’t set your basePath of your application.

Hello Ron, I was using a older version of Swagger UI(2.4.1) but I just updated to 2.1.4 and I still get the ERROR, if I add 

validatorUrl : null,

to 

window.swaggerUi = new SwaggerUi

 the ERROR disappears but i on't know if it's the correct way...

About the 404, how do I change the basePath?

[Ron Ratovsky]

It’s the correct way, though should be disabled automatically for localhost.

How do you setup swagger-core in your app? The way to set the basePath depends on the method of initialization you use.

I followed this tutorial: https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-1.X-Project-Setup-1.5#using-jerseys-container-servlet-with-webxml

Which of the methods did you go with under https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-1.X-Project-Setup-1.5#3-configure-and-initialize-swagger?

The one using Jersey Container Servlet in web.xml.

[Ron Ratovsky]

If you mean https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-1.X-Project-Setup-1.5#using-swaggers-servlet-in-the-webxml you’ll see there’s a parameter there to set the basePath. Make sure that’s the context root of your application where you host your endpoints. That should solve the problem.

It is:

<init-param>

      <param-name>swagger.api.basepath</param-name>

      <param-value>/PROJECT/</param-value>

</init-param>

Should it be something else?

[Ron Ratovsky]

It doesn’t seem to be picked up.

Check the swagger.json you get (the one loaded into swagger-ui) and see what the basePath is set to in it, if at all.

I assume you’re not using any of the BeanConfig methods as well because if you do, that would explain the clobbering.

So, i went to check the json and I had the basePath commented... Now the Requested URL is correct: http://127.0.0.1:8080/PROJECT/profile but it still returns the 404.

[Ron Ratovsky]

Can you share your entire web.xml?

It looks like your API is hosted under /jaxrs/ so try changing the basePath to that.

<init-param>

</init-param>

I changed to this and returns the same error.

[Ivan Sousa]

By the way, in the editor http://editor.swagger.io/#/ i also get an error and can't see the result.

[Ron Ratovsky]

Hi Ivan,

Sorry for the delay. Did you manage to work this out?

Hi Ron,

I managed to solve it, it was a problem that the jersey dependencies weren't being loaded by the server. Thanks for your help though.
