Please follow the steps below to implement the workaround: 1. Stop the IBM WebSphere Portal Server. 2. Find convertors.xml in <portal_server_root>/wp_profile/PortalServer/dcs 3. Backup this file to restore it after the fix has been applied. 4. Remove all <input> and <output> entries inside all <convertor> tags in the convertors.xml file as shown in the following example. Find all sections like this: <convertor> <input>application/vnd.openxmlformats-officedocument.wordprocessingml.document </input> <input>application/msword</input> <input>application/vnd.lotus-wordpro</input> <input>application/html</input> <input>application/rtf</input> ... <output>application/vnd.ibm-odcrte.zip</output> ... <property name="class" value="com.ibm.wps.odc.convert.text.Stellent2RTE"/> </convertor> and change them like this: <convertor> <property name="class" value="com.ibm.wps.odc.convert.text.Stellent2RTE"/> </convertor> 5. Restart the IBM WebSphere Portal Server.
