Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/eclipse/jetty/server/AbstractConnector

Question

I have got Spring project. I need to use JMX. I am using simplejmx - I found it really useful but unfortunately, I cannot manage few, basic things.

I wrote a really simple server:

package com.pckg.jmx;

import com.j256.simplejmx.web.JmxWebServer;

public class JMXServer {

    public static void main(String[] args) throws Exception {

        JmxWebServer jmxWebServer = new JmxWebServer(8123);
        jmxWebServer.start();
    }

}

with pom.xml:

<project...> 

    <properties>
        <jetty-version>8.1.9.v20130131</jetty-version>
    </properties>

    <dependencies>

        <dependency>
            <groupId>com.j256.simplejmx</groupId>
            <artifactId>simplejmx</artifactId>
            <version>1.8</version>
        </dependency>

        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-util</artifactId>
            <version>${jetty-version}</version>
        </dependency>

        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-server</artifactId>
            <version>${jetty-version}</version>
            <optional>true</optional>
        </dependency>

    </dependencies>

</project>

When I run it, it works well. I want to do it in Spring way. I created jmx-config file:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
        http://www.springframework.org/schema/batch http://www.springframework.org/schema/batch/spring-batch.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <!-- publishes classes that have @JmxResource or implement JmxSelfNaming 
        to jmxServer automagically -->
    <bean id="beanPublisher" class="com.j256.simplejmx.spring.BeanPublisher">
        <property name="jmxServer" ref="jmxServer" />
    </bean>

    <!-- our JmxServer which publishes our beans via JMX -->
    <bean id="jmxServer" class="com.j256.simplejmx.web.JmxWebServer"
        init-method="start" destroy-method="stop">
        <!-- the port should probably come from a configured property -->
        <property name="registryPort" value="8123" />
    </bean>

</beans>

I changed web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
    ...
    jmx-config.xml
    </param-value>
</context-param>

I added simple class:

package com.pckg.jmx;

import com.j256.simplejmx.common.JmxResource;

@JmxResource
public class DummyJMX {

    private int var = 3;
}

When I run my application I see warnings:

I was looking for a solution but I cannot fix it problem. My idea is that the problem is with pom.xml but I am not sure, moreover, I have no idea how to check it and what I should change.

Thanks in advance

Answer 1

You have the jetty-server dependency as optional and if you are packaging the code as war, it may be possible (depending on what other plugins and configuration settings you have in your pom) that jar not to be included in it. Check the resulting war file and test the packaging without <optional>true</optional> in your pom for 'jetty-server' dependency.

Answer 2

@Andrei Stefan answer solved this problem but anyhow, there is also another problem.

<bean id="jmxServer" class="com.j256.simplejmx.web.JmxWebServer"
    init-method="start" destroy-method="stop">
    <!-- the port should probably come from a configured property -->
    <property name="registryPort" value="8123" />
</bean>

There is no field registryPort in com.j256.simplejmx.web.JmxWebServer: Class JmxWebServer. It should be like this:

<bean id="jmxServer" class="com.j256.simplejmx.web.JmxWebServer"
    init-method="start" destroy-method="stop">
    <!-- the port should probably come from a configured property -->
    <property name="serverPort" value="8123" />
</bean>

I hope this will help somone in the future
