Swagger, Jersey and Tomcat 7.0.29

[marlandy]

Hi,

I´m trying swagger with Jersey (v 1.14) and Apache Tomcat 7.0.29. When Tomcat starts an OutOfMemoryError occurs.

With Tomcat 6.0.32 it works fine.

This is my servlet configuration:

<servlet>
        <servlet-name>JerseyTest</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>com.sun.jersey.config.property.resourceConfigClass</param-name>
            <param-value>com.sun.jersey.api.core.PackagesResourceConfig</param-value>
        </init-param>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.sample.swagger;com.wordnik.swagger.jaxrs</param-value>
        </init-param>
        <init-param>
            <param-name>swagger.api.basepath</param-name>
            <param-value>http://localhost:8080</param-value>
        </init-param>
        <init-param>
            <param-name>api.version</param-name>
            <param-value>1.0</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

Any ideas?

Thanks

Hi, can you try deploying the war from the sample in your tomcat container? Try this:

http://repo1.maven.org/maven2/com/wordnik/swagger-java-sample-app_2.9.1/1.1.0/

The same error occurs.

Can you show what your dependencies are? My guess is you're picking up the wrong version of scala

[marlandy]

These are my dependencies:

Howdy, I just got the swagger sample working fine with a fresh copy of tomcat. All I did was grab the sample war from here:

https://oss.sonatype.org/content/repositories/releases/com/wordnik/swagger-scala-sample-app_2.9.1/1.1.0/swagger-scala-sample-app_2.9.1-1.1.0.war

... and dump it in the webapps folder with the name "api.war". Sample started up just fine.

Could you please try to reproduce that step? You should be able to hit http://localhost:8080/api/resources.json once ./bin/catalina.sh start is executed.

I´ve got same error. Have you tried with Tomcat 7.0.29?

[fehguy]

Yep, I get that error on 7.0.29. Any chance you can use 7.0.32?

[fehguy]

I'm closing this as it seems like s 7.0.29 bug.
