Siebel JMX monitoring using JRuby

Question

Hi,
I am trying to use JRuby to monitor the performance of a Siebel adapter using JRuby. Whist I am able to read the mbean data from the server I am unable to successfully submit the command "reset = conn.invoke(name, 'Reset', '', '' )" The error message I receive is
D:\Scripts\JRuby\jmx.rb:17: for method RemoteMBeanServerConnection.invoke expected [class javax.management.ObjectName, class java.lang.String, class [Ljava.lang.Object;, class [Ljava.lang.String;]; got: [javax.management.ObjectName,java.lang.String,java.lang.String,java.lang.String]; error: argument type mismatch (TypeError)
     from C:/Program Files/jruby-1.4.0/lib/ruby/site_ruby/shared/builtin/java/java.util.rb:21:in `call'
     from C:/Program Files/jruby-1.4.0/lib/ruby/site_ruby/shared/builtin/java/java.util.rb:21:in `each'
     from D:\Scripts\JRuby\jmx.rb:15
The complete code is listed below.
#!/usr/bin/env jruby
include Java
include_class 'javax.management.ObjectName'
include_class 'javax.management.remote.JMXConnectorFactory'
include_class 'javax.management.remote.JMXServiceURL'
jmxurl = 'service:jmx:rmi:///jndi/rmi://localhost.au:8687/jmxrmi'
username, password = 'admin', 'sun12345'
svcurl = JMXServiceURL.new(jmxurl)
cred = java.lang.String[2].new
cred[0], cred[1] = username, password
env = {'jmx.remote.credentials' => cred}
conn = JMXConnectorFactory.connect(svcurl, env).getMBeanServerConnection
names = conn.query_names(ObjectName.new( 'IDM:serverName=localhost,resourceAdapterType=CCB Siebel CRM Position,resourceAdapterName=CCB Siebel CRM Position'), nil)
names.each do |name|
    puts "OperationCount: #{conn.get_attribute(name, 'Account_Get_OperationCount')} " + "OperationMaxTime: #{conn.get_attribute(name, 'Account_Get_OperationMaxTime')}"
    reset = conn.invoke(name, 'Reset', '', '' )
end
