Step 1. Update the logger

BW 5.13.x

Set the logger httpclient.wire to DEBUG in TIBCO_HOME/bw/5.13/lib/log4j.xml on the machine where Designer/deployed application is running.

Before:

 <logger name="httpclient.wire">

  <level value ="WARN"/>

     <appender-ref ref="tibco_bw_log"/> 

 </logger>

After:

<logger name="httpclient.wire">

     <level value ="DEBUG"/>

     <appender-ref ref="tibco_bw_log"/> 

</logger>

BW 5.14

Add the following logger to TIBCO_HOME/bw/5.14/lib/log4j.xml on the machine where Designer/deployed application is running.

<logger name="org.apache.http.wire">

<level value ="DEBUG"/>

<appender-ref ref="tibco_bw_log"/>

</logger>

Step 2. Restart Designer/deployed application

Step 3. Messages will be written to Designer console/deployed application log.
