Debugging Bonita – Tips and Tricks

To see the Bonita Engine Log for debugging issues:

• Use Cygwin (a version of a unix shell in windows) http://cygwin.com/install.html
• use the tail program with this line of code

   tail /cygdrive/c/BOS-5.9/studio/workspace/.metadata/engine.log --lines=300 --follow
   

Insert an HTML widget for debugging

• In the pool header – I have created a global map called “configMap” and there is an item ‘debug’
• insert HTML widget into any page and have it shown conditionally upon configMap[‘debug’] having a true value

Writing to the Bonita Log

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;
 Logger LOGGER = LoggerFactory.getLogger(this.getClass());
 LOGGER.error("Your String Here");
 

Debugging on the Server

Here is what I do know … there is hope and things are NOT the same as on a development  computer or situation

• The debug output from System.out.printn from Java DOES go into 1 of 3 logs (will edit this when I get paths)
• The output from the logging routine above goes to another log (will edit this when I get paths)
• The output from the server hosting things like Tomcat goes to a 3rd log (will edit this when I get paths)
