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
