Invoking java class within SoapUI

Hello Team,

I'm trying to execute a custom java class within a Groovy script.

Getting......
groovy.lang.MissingMethodException: No signature of method: Script15.EmitLog() is applicable for argument types: () values: [] Possible solutions: wait() error at line: 3

1. Java can be executed at the command line.
2. Created jar file within eclipse
3. Dropped file into C:\Program Files\SmartBear\SoapUI-5.0.0\bin\ext\
4. Code in java class is

import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import java.util.UUID;



public class EmitLog {

private static final String EXCHANGE_NAME = "logs";

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

ConnectionFactory factory = new ConnectionFactory();
factory.setHost("127.0.0.1");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();

channel.exchangeDeclare(EXCHANGE_NAME, "fanout");

String message = getMessage(argv);

channel.basicPublish(EXCHANGE_NAME, "", null, message.getBytes());
System.out.println(" [x] Sent '" + message + "'");

channel.close();
connection.close();
}

private static String getMessage(String[] strings){
if (strings.length < 1)
return
"This is a test message";



return joinStrings(strings, " ");
}

private static String joinStrings(String[] strings, String delimiter) {
int length = strings.length;
if (length == 0) return "";
StringBuilder words = new StringBuilder(strings[0]);
for (int i = 1; i < length; i++) {
words.append(delimiter).append(strings);
}
return words.toString();
}
}

5. Code in groovy

import EmitLog;

EmitLog();

Please help.
