Hi,
When I send a message to fetch meeting usage history, I get an error, code 999999, that says "validation: unable to instantiate com.webex.xmlapi.service.binding.LstmeetingusageHistory; java.lang.ClassNotFoundException: com.webex.xmlapi.service.binding.LstmeetingusageHistory". Has anyone else seen this, or is there even someone with a solution?

Hi Ingemar,
In your bodyContent tag try changing the "L" in LstmeetingusageHistory to an uppercase letter. If that doens't help then try additn the full XSI type to
<bodyContent xsi:type="java:com.webex.service.binding.history.LstmeetingusageHistory">
Thank you,

Thanks, but that's not really going to work. I do not write the XML myself, that is done by classes generated from the WebEx XML schemas by Apache XMLBeans. I have verified that the request messages validate against the XML schemas published by WebEx, and sure, the requests validate just fine.
If I understand correctly, your solution implies that the XML schemas published here are wrong, and do not match the messages expected by the WebEx XML API.
In addition, I just tried validating your suggested modifications against the WebEx XML schemas published here, and they won't validate.

Hi Ingemar,
The only supported xsi:type is the full path of
xsi:type="java:com.webex.service.binding.history.LstmeetingusageHistory"
or a shortened path of
xsi:type="history.LstmeetingusageHistory"
If your XML Code generator cannot be modified to support this then you may have to manually modify this in the generated code it provides.
As for the schema - You are correct, it is wrong for the list meeting usage command. I'll have the engineering team fix it in the next release.
The below XML will work successfully
<?xml version="1.0" encoding="UTF-8"?>
<serv:message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I have the same problem with lstmeetingusageHistory operation.
But I have no time for wait the new release, therefore I want manually edit my XSD file.
Could you tell me what wrong with history.xsd scheme?
Thank you.

Hi Yuriy,
In the schema change lstmeetingusageHistory to LstmeetingusageHistory, but leave the response lower case.
Thank you,

I have changed only one line, but the scheme become not compilable:
original line:
<xsd:complexType name="lstmeetingusageHistory">
modified line:
<xsd:complexType name="LstmeetingusageHistory">
Than I changed one more line:
original line:
<xsd:extension base="history:lstmeetingusageHistory">
modified line:
<xsd:extension base="history:LstmeetingusageHistory">
Than I have compiled my scheme with the 2 changed lines, buut the problem is live - unable to instantiate com.webex.xmlapi.service.binding.LstmeetingusageHistory.

Hi Yuriy,
It looks like the command is missing the history part. The correct xsi:type should be
<bodyContent xsi:type="java:com.webex.service.binding.history.LstmeetingusageHistory">
You may have to manually add this to the code if you are using some code generation tools.
Thank you,

Hi, Kingsley!
I have replaced my uncorrect line
<bodyContent xsi:type="his:LstmeetingusageHistory" xmlns:his="http://www.webex.com/schemas/2002/06/service/history">
to new line
<bodyContent xsi:type="java:com.webex.service.binding.history.LstmeetingusageHistory">
and received SUCCESS response.
Thank you very much!
Could you tell me when this bug will be fixed and a new version of the scheme will be created?
