Is jaxrs:server required for cxf:rsServer when using camel? - rest

I'm struggling to get a simple cxf:rsServer to listen on a port.
My appContext:
<bean id="transformer" class="com.xyxx.portlistener.services.Transformer">
</bean>
<cxf:rsServer id="pushServer"
address="tcp://localhost:9090/hrm/hrm_push?bindingStyle=SimpleConsumer;resourceClasses=com.xyxx.portlistener.services.Transformer" >
<cxf:serviceBeans>
<ref bean="transformer" />
</cxf:serviceBeans>
</cxf:rsServer>
<!-- Camel Configuration -->
<camel:camelContext id="camel-1" xmlns="http://camel.apache.org/schema/spring">
<package>com.xyxx.portlistener.services</package>
<camel:route id="route1">
<camel:from uri="cxfrs://bean://pushServer"/>
<camel:to uri="log:TEST?showAll=true" />
</camel:route>
</camel:camelContext>
My exception:
MethodInvocationException: Property 'serviceBeans' threw exception; nested exception is java.lang.NoClassDefFoundError: javax/servlet/http/HttpServletRequest
My camel version 2.4.0 pom.xml:
<dependency>
<groupId>org.apache.camel</groupId>

3 confusing issues with HTTP and that exception
I'm running camel as standalone so I don't think I need a Servlet.
pushServer is using tcp:// not http:/
transformer is a pojo and knows nothing about HTTP
Question: In most of the xml examples regarding cxf:rsServer I've seen jaxrs:server configured. That is one thing I do not have. Do I need it?
Thanks for reading. All suggestions are welcome.
Andrew

The jaxrs:server shown in the examples is simulating a remote REST web service to complete the routing example.
Route From: cxf:rsServer
Route To: cxf:rsClient
The CXF RS client needs to send the message somewhere, which is what the JAX RS server running on a different port is used for.
Since your route destination above is something else (a log component) you have no need for the JAX RS server configuration.

Not Able to Access Swagger UI with spring mvc, Getting 404

I have Configured swagger with my application(Spring MVC), I can see the documentation in JSON format if I am accessing https://IP:port/app/v2/api-docs.

Analysis:
Pivotal jars required write permissions when start geode connection with gemfire cluster .
Pivotal code :
https://github.com/ashishtadose/gemfire-xd/blob/master/gemfire-core/src/main/java/com/gemstone/gemfire/internal/JarDeployer.java
Pivotal Doc:
- https://gemfire.docs.pivotal.io/98/geode/configuring/cluster_config/deploying_application_jars.html
If gemfire.properties is specified then Geode locator fails to start
https://www.mail-archive.com/issues#geode.apache.org/msg17105.html
https://issues.apache.org/jira/browse/GEODE-5000?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel
Pivotal doc says if we can remove "deploy-working-dir"inside "gefire.properties" will resolve issue else use "-Dgemfire.deploy-working-dir=/temp/
Problem :
inside Spring batch we are not configuring any gemfire properties , how to fix it in GemfireTemplate code ?
The issue is clearly the same as the one described by the Geode Ticket you attached to the question, GEODE-5000. This particular ticket is fixed in Geode 1.6.0 and, according to the Pivotal GemFire User Guide, specifically the Release Notes, GemFire 9.5 is based on Geode 1.6.0, so you should be using that version instead of 9.3.0 to get rid of the problem.
As a side note, you shouldn't be arbitrarily mixing and matching spring-data-gemfire and gemfire versions as several issues might rise, please follow the Spring Data for Pivotal GemFire Version Compatibility Matrix to avoid issues.
Hope this helps. Cheers.

zuul multiple urls one path

Hi I have a route that can have multiple servers...
I have tried the following to no luck:
zuul.routes.example.path=/example/**
zuul.routes.example.serviceId=example
example.ribbon.eureka.enabled=false
example.ribbon.eureka.listOfServers=http://127.0.0.1/metrics,http://127.0.0.1/info
This just returns the following error:
Caused by: com.netflix.client.ClientException: Load balancer does not have available server for client: example
I am using eureka for most routes, but for this one in particular I cannot use eureka.
Is it possible to get zuul to loadbalance between the two urls?
Solved
The answer below solves this issue with config, however I would mention I was using spring-boot-starter-parent, I also had to upgrade the dependency management to Camden.SR7
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<!-- <version>Brixton.SR5</version> -->
<version>Camden.SR7</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Yes, you can. Try the following properties instead of yours.
zuul.routes.example.path=/example/**
zuul.routes.example.serviceId=example
example.ribbon.NIWSServerListClassName=com.netflix.loadbalancer.ConfigurationBasedServerList
example.ribbon.listOfServers=http://127.0.0.1/metrics,http://127.0.0.1/info

SpringCloud Eureka - simple client doesnt register

I have an Eureka Server where I want to register a very basic SpringBoot service. Unfortunately the service doesnt register although I tried to follow all the articles I could find.
Moreover when I check description of the DiscoveryClient (that gets autowired), I see "Spring Cloud No-op DiscoveryClient" which suggests (as per NoopDiscoveryClient.java source) that Eureka client library isnt found.
In pom I have
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-eureka-client</artifactId>
</dependency>
which if I am right should make sure that proper netflix libraries are in place. #EnableEurekaClient annotation is present. No errors on the console when starting the client, nothing interesting in the Eureka Server console logs.
This is the configuration from the application.yml:
eureka:
client:
serviceUrl:
defaultZone: ${vcap.services.eureka-service.credentials.uri:http://127.0.0.1:8761}/eureka/
Any suggestions are really welcomed as I am running out of ideas :)
http://start.spring.io is your friend. You need to use the starters.

Except #spencergibb's answer, in my case it also require <spring-cloud.version> inside the <properties>:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.M3</spring-cloud.version>
</properties>

"Provider not a subtype" on org.eclipse.jetty.apache.jsp.JuliLog for Embedded Jetty

Any pointers to a correctly configured embedded jetty (preferably also using websockets) appreciated.
Don't try to enable everything all at once.
Jetty is a highly modular system, you can pick and choose what you want to run. Nothing is mandatory by default, even the Server!
If you want examples of embedded jetty with websockets, consider reviewing the example projects that the Jetty project has put together at ...
https://github.com/jetty-project/embedded-websocket-echo-examples
Some advice:
Build up your requirements layer by layer
Start with basic websocket endpoint functionality (get this working first!)
then add slf4j + logback. (be sure you use an appropriate version, see the <scope>optional</scope> dependencies present in your previous layer before you choose a version of slf4j or logback). Test this like there is no tommorrow.
then add jsp support (as your error seems to indicate your desire for jsp support)
