Java Development Tools

Hi all,
I am trying to change the directory of where files are stored temporarily when being uploaded to WL. I found two config file properties that seemed promising. But adding these configs did not change the default directory that the files are being uploaded to.
web.xml

 <context-param>
  <param-name>org.apache.myfaces.trinidad.UPLOAD_TEMP_DIR</param-name>
  <param-value>/data/tmp</param-value>
 </context-param>

trinidad-config.xml

 <uploaded-file-temp-dir>/data/tmp</uploaded-file-temp-dir>

Both of these approaches did not work and the file continued to be uploaded to the default directory "/tmp"
Any ideas? I'm using JDeveloper 12.2.1.4, same for WLS.

Thanks,
Bill
