Enter the ProtectDebugInfo Transaction Participant a configurable implementation I wrote based on some of Alejandro’s ideas, and one that lives in most of OLS’s payment products in various specific iterations.

It’s configuration looks like:

Protecting your q2.log in this truncated example:

<entry key=‘FSDMESSAGE’>
<fsdmsg schema=‘file:cfg/fsd-base’>
account-number: ’599999______0001′
</fsdmsg>
</entry>
<entry key=‘PAN’>599999______0001</entry>
<entry key=‘RESPONSE’>
<isomsg direction=“incoming”>
<field id=“0″ value=“2110″/>
<field id=“2″ value=“599999______0001″/>
<field id=“35″ value=“599999______0001=____________________”/>
</isomsg>
</entry>
<entry key=‘REQUEST’>
<isomsg direction=“incoming”>
<field id=“0″ value=“2100″/>
<field id=“2″ value=“599999______0001″/>
<field id=“35″ value=“599999______0001=____________________”/>
</isomsg>
</entry>

You need to configure a TwitterLogListener in your logger:

<log-listener class="org.jpos.util.TwitterLogListener">
 <property name="twitterUsername" value="paymentsystems" />
 <property name="twitterPassword" value="SuperSecretPassword" />
 <property name="tags" value="twitter" />
 <property name="prefix" value="[jPOS]"/>
 </log-listener>

And you need to Log an event with a ‘twitter’ tag:

<script name="test" logger="Q2">
     import org.jpos.util.*;
         for (int i=0; qbean.running(); i++) {
              LogEvent evt = log.createLogEvent ("twitter");
              evt.addMessage ("This is a Twitter message test from jPOS! " +   i);
              Logger.log (evt);
	           Thread.sleep (10000L);
       }
</script>

Look at the messages in a twitter account: http://twitter.com/paymentsystems
