Debugging Logs and Messages

Logs and messages can also be used for debugging purposes. The log.info () method is available to enable Fabric’s runtime Debug options. This method can be added to any Java code and its output can be viewed after deployment and during runtime.

For example, see the fnCreateInstID function under Customer LU in the demo project:

if (i_id!=null && !i_id.isEmpty()){
// Increase the input by 10 and return
   log.info("o_id: "(Integer.sum(Integer.valueOf(i_id),10)+""));
    return Integer.sum(Integer.valueOf(i_id),10)+"";
}
return "0";

The runtime log (k2fabric.log) can be reviewed in the Fabric Server’s Logs directory or in the Studio’s Output logs.
