java.lang.NoClassDefFoundError

Tue, 10 Sep 2013 19:47:51 -0700 

Hi all,
I am adding a plugin to CloudStack. One of the APIs of this plugin (launchCluster) is to start a haoop cluster on Cloudstack using Whirr. I included whirr as a dependency to my plugin. 

<dependency>
      <groupId>org.apache.whirr</groupId>
      <artifactId>whirr</artifactId>
      <version>0.8.2</version>
      <type>pom</type>
</dependency>


When I test this api in CloudMonkey I am getting the following error:


launchCluster config=/home/meng/whirr/dream

HTTP Error 500: java.lang.NoClassDefFoundError: 
org/jclouds/json/config/GsonModule$DateAdapter


Below is the management server log :

The execute method for the lauchClusterCmd is below:

 public void execute()  {

        LaunchClusterResponse response = new LaunchClusterResponse();
        response.setObjectName("launchCluster");
        LaunchClusterCommand command = null;
        try {

            command = new LaunchClusterCommand();  //imported from  
org.apache.whirr.cli.command.LaunchClusterCommand;

        } catch (Exception ex) {

            
Logger.getLogger(LaunchClusterCmd.class.getName()).log(Level.SEVERE, 
null, ex);

        }
        String[] args = new String[2];
        args[0] = "--config";
        args[1] = config;

        try {

            command.run(System.in, System.out, System.err, 
Arrays.asList(args));

        } catch (Exception ex) {

            
Logger.getLogger(LaunchClusterCmd.class.getName()).log(Level.SEVERE, 
null, ex);

        }
         response.setResponseName(getCommandName());
         output = "successfully launched the cluster.";
         response.setOutPut(output);
         this.setResponseObject(response);
    }

Does the  above error indicate that I am missing a couple of class 
files or am I not configuring the JAVA classpath correctly?



Also could someone explain what does this file 
client/target/conf/classpath.conf do ?



Thanks.

Cheers,
Meng
