Common Cause

You might encounter this problem if your file names contain unicode characters (for example, $ or %). Apache Tomcat does not support unicode characters in file names by default. You must update the URIEncoding attribute in the server.xml file. Refer to the documentation at


Update the URIEncoding attribute.

  1. Log on to the SmartPlant Markup Plus Server as an administrator.

  2. Open the server.xml file delivered to the [installation location]\Apache Software Foundation\Tomcat [version]\conf\ folder.

  3. Set maxHttpHeaderSize to "UTF-8".

  4. Save the file.
