Error running the application as WAR in tomcat 9

[khteh]

I use Spring Boot 2.1.0.RELEASE to build and install the application as WAR format on Tomcat9 and bump into the following exception when tomcat restarts:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'serverEndpointExporter' defined in class path resource [com/oembedler/moon/graphql/boot/GraphQLWebAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

Any advice and insight is appreciated

I haven't had the time to update this project to the latest versions of Spring Boot and graphql-spring-boot, but you only mention Spring Boot, did you update graphql-spring-boot-starter and graphql-java-tools too? Does it work when you run the application as a JAR or from an IDE?

[khteh]

Yes, I have upgraded everything to the latest. No problem running it as JAR. Only WAR and this exception.

Okay, so probably the problem is in the way you generate the WAR file. How you do it?
I have successfully deployed this project in Tomcat following the steps outlined in:

• https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
• https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/

Just tried. Doesn't help. Here is the runtime exception stack trace:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

The guides provided in the URLs do not use graphql-spring-boot-starter which is causing the issue. I remove that dependency the exception disappears but there is no servlet to generate the graphql schema. Besides, I receive 302 status code when POSTing to the endpoint using GraphIQL.

Hi @khteh.

Sorry, I didn't have time to look at this issue until now.

I remembered I deployed this project in Tomcat successfully, but now that I tried again, it didn't work. The application was throwing the exception you mentioned in the first comment (and I didn't update the project to the latest versions of Spring Boot and GraphQL).

Anyway, a search led me to this issue, which refers to another issue that includes a fix that apparently it's not needed anymore. But it is.

The application works for me now. I deployed it with the context /grapqhl and access it at http://localhost:8080/graphql/graphql with the GraphiQL Desktop tool.

Here's the class DemoGraphQlApplication (without import statements):

@SpringBootApplication
public class DemoGraphQlApplication extends SpringBootServletInitializer {

	public static void main(String[] args) {
		SpringApplication.run(DemoGraphQlApplication.class, args);
	}

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(DemoGraphQlApplication.class);
	}

	@Bean
	public ServletContextAware endpointExporterInitializer(final ApplicationContext applicationContext) {
		return new ServletContextAware() {

			@Override
			public void setServletContext(ServletContext servletContext) {
				ServerEndpointExporter serverEndpointExporter = new ServerEndpointExporter();
				serverEndpointExporter.setApplicationContext(applicationContext);
				try {
					serverEndpointExporter.afterPropertiesSet();
				} catch (Exception e) {
					throw new RuntimeException(e);
				}
			}
		};
	}

	@Bean
	public GraphQLErrorHandler errorHandler() {
		return new GraphQLErrorHandler() {
			@Override
			public List<GraphQLError> processErrors(List<GraphQLError> errors) {
				List<GraphQLError> clientErrors = errors.stream()
						.filter(this::isClientError)
						.collect(Collectors.toList());

				List<GraphQLError> serverErrors = errors.stream()
						.filter(e -> !isClientError(e))
						.map(GraphQLErrorAdapter::new)
						.collect(Collectors.toList());

				List<GraphQLError> e = new ArrayList<>();
				e.addAll(clientErrors);
				e.addAll(serverErrors);
				return e;
			}

			protected boolean isClientError(GraphQLError error) {
				return !(error instanceof ExceptionWhileDataFetching || error instanceof Throwable);
			}
		};
	}

	@Bean
	public BookResolver authorResolver(AuthorRepository authorRepository) {
		return new BookResolver(authorRepository);
	}

	@Bean
	public Query query(AuthorRepository authorRepository, BookRepository bookRepository) {
		return new Query(authorRepository, bookRepository);
	}

	@Bean
	public Mutation mutation(AuthorRepository authorRepository, BookRepository bookRepository) {
		return new Mutation(authorRepository, bookRepository);
	}

	@Bean
	public CommandLineRunner demo(AuthorRepository authorRepository, BookRepository bookRepository) {
		return (args) -> {
			Author author = new Author("Herbert", "Schildt");
			authorRepository.save(author);

			bookRepository.save(new Book("Java: A Beginner's Guide, Sixth Edition", "0071809252", 728, author));
		};
	}
}

Apparently, the method endpointExporterInitializer is what did the trick.

I generated the WAR file with mvn clean package -Dmaven.test.skip.

Hope it helps.

Unfortunately it doesn't work for me here. I am using Java 11 Tomcat 9. I juet get the similar exception with different symbol now pointing to the added bean "endpointExporterInitializer":

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'endpointExporterInitializer' defined in class path resource [com/graphql/book/AppConfig.class]: Initialization of bean failed; nested exception is java.lang.RuntimeException: java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

Oh sorry, I reviewed my version of Tomcat, it's 8.5. I downloaded Tomcat 9 and yes, it doesn't work.

Well, I guess we should have to wait for the issue you opened in the graphql-java-kickstart project to be resolved.

Thanks @eh3rrera

I managed to make it work with tomcat version 9.0.8, as I mentioned in the following comment, I hope it helps.

Thanks @adexerivera! 👍
