Hi all
I would like to get
ShortName.CURRENT_BYTE_SIZE cs value from the lamp example.
@XmlElement(required = true, name = ShortName.CURRENT_BYTE_SIZE)
@XmlSchemaType(name = "nonNegativeInteger")
How can I get DAO value from the Lamp IPE Example?
Do you have any sample code?
Thanks for your help!!

Hello,

Could you please clarify a bit?
I don't really understand: are you trying to get the current byte size value of a specific container through the REST Api, or directly in the code?

Regards,
Guillaume

My purpose is to directly access H2 database value.
The lamp sample code includes some data resocure tree. Whenever I click the lamp0, lamp1 and I can see the lamp information, for example, resource byte size, location, type, etc. in the webUI.
I think these resource information is sotred in a xml file for H2 database.
I hope to access the H2 databse. Do you have any sample code for this? Thanks a lot.

Hello Emelie

Technically it is possible. But, I don't understand why you need to have such direct access to the H2 database. This is against the concept of interoperability. Why not simply access the information through the current Restful API ? Do you something missing ?
Please give more details about your use case.

You are welcome.

I am just curious that how to compute each lamp on/off "cs" value to sum the "cbs" value because I can't see the source code in the om2m source code. I think you store the "cs" value in the H2 database and after that it can easily to do DAO manager easily and compute the accumulate value.
I don't know which REST API can do this. Is is possible to do by JAXB? How can I do?
Thanks.
