Re: [Sblim-devel] Help for implementing indication provider

[George v. <geo...@gm...>]

Thank you.



I had implemented a sample provider using the reference of implementation
in sblim-base , operating system source code. Then I tried testing with
wbemcli.

I have created /tmp/SFCB_OS_Listener.txt file ans set it the destination
path.


I executed the following command,



> wbemcat SFCBCreateFilter.localhost.xml

> wbemcat SFCBCreateHandler.localhost.xml

> wbemcat SFCBCreateSubscription.localhost.xml


When I open the file it contains , indication contents cim xml, is not well
formatted. Please see it ,


<PROPERTY NAME="Generation" TYPE="uint64">

</PROPERTY>

<PROPERTY NAME="ElementName" TYPE="string">

</PROPERTY>

<PROPERTY NAME="Caption" TYPE="string">

</PROPERTY>

<PROPERTY NAME="PrimaryStatus" TYPE="uint16">

</PROPERTY>

<PROPERTY NAME="OperatingStatus" TYPE="uint16">

</PROPERTY>

<PROPERTY NAME="DetailedStatus" TYPE="uint16">

</PROPERTY>

<PROPERTY NAME="CommunicationStatus"
TYPE="uint16">

</PROPERTY>

<PROPERTY NAME="HealthState" TYPE="uint16">

</PROPERTY>

<PROPERTY NAME="Status" TYPE="string">



Please help me, if you know the reason for this kind of invalid xml file.


Regards,

George
