RESTEASY003880: Unable to find contextual data of type: javax.servlet.ServletConfig #1691

natros · 2016-03-02T15:04:14Z

This is happening after updating from swagger 1.5.6 to 1.5.6. I'm using jetty-maven-plugin with resteasy 3.0.16

@natros this is possibly related to #1491, could you specify old and new version, and possibly share configuration?

natros · 2016-03-02T16:26:09Z

I think I know what the problem is. I'm bootstrapping resteasy with a filter dispatcher rather than a servlet dispatcher, so the ServletConfig is not available in this case. Apparently this last version of swagger is using getInitParameter from ServletConfig that restasy can not provide.

frantuma · 2016-03-02T16:35:17Z

last version uses indeed ServletConfig if not null, also previous versions do actually in some configurations like the ones affected by #1491. as you said in your case ServletConfig is not available, but it's not null and I would say possibly this is related to solution mentioned in #1491. This will need some investigation, as workaround you could change resteasy bootstrap or try #1491 solution

natros · 2016-03-02T17:35:46Z

I don't think it's related to #1491. In my case the ServletContext is set and is valid, but the same does not happen with ServletConfig. IIRC, the ServletConfig is one for each servlet while the ServletContext is for all servlets.
For now I cannot change the bootstrap.

public User getMessage(@Context ServletContext ctx, @Context ServletConfig cfg) {
}

The debugger shows me this

cfg = {$Proxy62@8445} Method threw 'org.jboss.resteasy.spi.LoggableFailure' exception. Cannot evaluate com.sun.proxy.$Proxy62.toString()
ctx = {$Proxy59@8444} "ServletContext@o.e.j.m.p.JettyWebAppContext@9accff0{/,[file:///Users/fsousa/Projects/demo/swagger2-demo/src/main/webapp/, jar:file:///Users/fsousa/.m2/repository/org/webjars/swagger-ui/2.1.4/swagger-ui-2.1.4.jar!/META-INF/resources],AVAILABLE}{file:///Users/fsousa/Projects/demo/swagger2-demo/src/main/webapp/}"

@natros, yep issue is with servletConfig being not null but "invalid" in RESTEasy filter based; a fix is available in PR #1692 and will be available soon in 1.5.8-SNAPSHOT and in next release v1.5.8

natros · 2016-03-02T22:56:55Z

I'll try as soon as possible.

Thank you.

Fix #1691 - fixes ServletConfig related error in RESTEasy Filter based config

afredlyj · 2016-08-20T04:51:53Z

The exception still exist since I change to 1.5.8:

        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-jaxrs</artifactId>
            <version>1.5.8</version>
        </dependency>

and the error log ：

@afredlyj log seems to be correct (INFO level) it just signals the "invalid" servlet config, and adopts appropriate behavior; previously you would get a blocking error instead

afredlyj · 2016-08-23T15:49:45Z

I use netty + resteasy + swagger, but still something is wrong when request http://127.0.0.1:12345/swagger.son, the response from server is ：

RESTEASY003880: Unable to find contextual data of type: javax.servlet.ServletContext

this is my spring xml ：

    <bean id="apiListingResourceJSON" class="io.swagger.jaxrs.listing.ApiListingResource"/>
    <bean id="apiDeclarationProvider" class="io.swagger.jaxrs.listing.SwaggerSerializers"/>

    <bean id="beanConfig" class="io.swagger.jaxrs.config.BeanConfig" lazy-init="false">

I opened a new issue, because I use resteasy with google guice and I dont use the default implementation of resteasy servlet dispatcher. You can see how I resolved this in #2239
