IssueWould like to be able to open Event Explorer

When trying to connect with the Event Explorer, the application returns the following error:

Invalid Server Configuration: <hostname> org.xml.sax.SAWParseException: Invalid byte 1 of 1-byte UTF-8 sequence

Resolution

This error is generated when an Envision device contains invalid characters.

If you do not believe you have a device with an invalid character, you can do the following to confirm:

 1. Make a note of the URL you use to log into the Envision UI.

 2. Open your browser and point it at:

  <Your normal Envision URL>/event_explorer/ee-metadata.jsp

         So, for example, if you normally log into:

  http://1.2.3.4:8080

    In your browser URL line, you would enter:

  http://1.2.3.4:8080/event_explorer/ee-metadata.jsp

 3. When challenged by the authentication page, authenticate as normal.

 4. When the XML page comes up, save this page as type *.xml
 
 5. Open the saved page in a standard ASCII editor (notepad or wordpad, for example).
 
 6. Search for "<device>" and you will come across one that has invalid characters.  Here's an example of a device with invalid characters:

<device>
<id><![CDATA[dba6006c-fcc2-4641-bc3e-a98c5031e771]]></id>
<type><![CDATA[Unknown]]></type>
<ip><![CDATA[null,true,null,null,????]]></ip>
<site><![CDATA[NCCI-LOG]]></site>
<domain><![CDATA[NIC]]></domain>
<category><![CDATA[Unknown]]></category>
</device>

This normally occurs when you have removed a device and then readded it.  If you have recently removed a device and then readded it please try removing the device and logging into Event Explorer.  After logging into Event Explorer you should be able to readd the device again and log into Event Explorer again.
