Error Troubleshooting

HTTP request error

Symptom

When attempting to upload images via HTTP Put the images fail to upload and this error is received.

Cause

• The problem may occur if write permission is not provided on the server.
• If you use Tomcat, the value of the readonly property is false by default, in this case the HTTP Put operation is not allowed.

Solution

• Check the write permission of the server.

  • Start Internet Information Services (IIS).
  • Click Web Sites.
  • Right-click the specified work folder, select Properties.
  • Select the Write option at the Directory tab.

• If you are using Tomcat, the doPut() will check to see if the readonly property has been changed to false. If it has not, the HTTP Put operation is not allowed. Please go to {Tomcat installation directory} -> conf -> web.xml, find the default servlet configuration (org.apache.catalina.servlets. DefaultServlet) and change the readonly property to true .
