The following instructions make it easy to post to Twitter and Jaiku from the command line. The instructions were copied from the article "Ubuntu Unleashed: Howto Twitter From the Command Line in Ubuntu!" [ubuntu-unleashed.com] and modified to post via Rorbuilder's ProjectX API.

   1  sudo apt-get install curl

   1  sudo gedit /usr/bin/jaitwit

Now Paste this in gEdit and simply replace "YourUsername" with your username and "YourPassword" with your twitter passwd, then replace the Jaiku variables (YourUsername, YourPassword, YourCity, YourAccessKey) and ctrl-s to save, then alt-F4 to exit!

   2  curl http://rorbuilder.info/api/projectx.cgi?xml_project=%3Cproject%20name=%22micro_blog%22%3E%3Cmethods%3E%3Cmethod%20name=%22post2jaiku%22%3E%3Cparams%3E%3Cparam%20var=%22user%22%20val=%22YourUsername%22/%3E%3Cparam%20var=%22msg%22%20val=%22`echo $@|tr ' ' '+'`%22/%3E%3Cparam%20var=%22location%22%20val=%22YourCity%22/%3E%3Cparam%20var=%22apikey%22%20val=%22YourAccessKey%22/%3E%3C/params%3E%3C/method%3E%3Cmethod%20name=%22post2twitter%22%3E%3Cparams%3E%3Cparam%20var=%22user%22%20val=%22YourUsername%22/%3E%3Cparam%20var=%22msg%22%20val=%22`echo $@|tr ' ' '+'`%22/%3E%3Cparam%20var=%22password%22%20val=%22YourPassword%22/%3E%3C/params%3E%3C/method%3E%3C/methods%3E%3C/project%3E -o /dev/null
   3  echo Message Sent!

Then chmod for exec privileges:

   1  chmod +x /usr/bin/jaitwit

Then from the CLI type jaitwit followed by your message.

   1  jaitwit "message here without the quotes"

This example uses the ProjectX API to post to Jaiku.com

   1  
   2  <?php
   3    $msg = 'this is just a test message using the ProjectX API for posting to Jaiku';
   4  
   5    $xml_result =  simplexml_load_file('http://rorbuilder.info/api/projectx.cgi?xml_project=<project name="jaiku"><methods><method name="post"><params><param var="user" val="jrobertson"/><param var="msg" val="' . $msg . '"/><param var="location" val="London"/><param var="apikey" val="9ee6ffd165r364492"/></params></method></methods></project>');
   6    $method_result = $xml_result->post2jaiku;
   7    echo 'result' . $method_result;
   8  ?>

Reference: SimpleXML processing with PHP [ibm.com]

This XML code is the ProjectX API to post to both Twitter and Jaiku. This is a follow-up example from Post to Jaiku using ProjectX API [dzone.com]

   2  xml_project = <<PROJECT
   3  <project name='micro_blog'>
   4    <methods>
   5      <method name='post2jaiku'>
   6        <params>
   7          <param var='user' val='YourJaikuUserName'/>

This Ruby code uses the ProjectX API on rorbuilder.info to send a post to Jaiku.

Prerequisites:
1) You have a Jaiku account. see http://jaiku.com/
2) You know your Jaiku API key. see http://api.jaiku.com/

   1  
   2  #!/usr/bin/ruby
   3  # file: projectx_client.rb
   4  
   5  require 'net/http'
   6  require 'rexml/document'
   7  include REXML
   8  
   9  class ProjectXClient
  10    attr :doc
  11    def initialize(raw_url)
  12      url = URI.escape(raw_url)
  13      xml_data = Net::HTTP.get_response(URI.parse(url)).body
  14      @doc = Document.new(xml_data)
  15    end
  16    
  17  end
  18  
  19  if __FILE__ == $0
  20  
  21  xml_project = <<PROJECT
  22  <project name='jaiku'>
  23    <methods>
  24      <method name='post'>
  25        <params>
  26          <param var='user' val='YourJaikuUserName'/>
  27          <param var='msg' val='YourMessage'/>
  28          <param var='location' val='YourCity'/>
  29          <param var='apikey' val='YourApiKey'/>
  30        </params>
  31      </method>
  32    </methods>
  33  </project>"
  34  PROJECT
  35    
  36    pxc = ProjectXClient.new("http://rorbuilder.info/api/projectx.cgi?xml_project=" + xml_project)
  37    doc = pxc.doc
  38    puts doc
  39      
  40  end
  41  

You can also pass the url including xml into the address bar and it will post to Jaiku successfully.
eg.
http://rorbuilder.info/api/projectx.cgi?xml_project="<project name='jaiku'><methods><method name='post'><params><param var='user' val='jrobertson'/><param var='msg' val='testing 223'/><param var='location' val='London'/><param var='apikey' val='5ugr6ttr754y214445'/></params></method></methods></project>"
