is there a simple way to serialize dlms object into xml or json (even better)?
Serializing Dlms object
Hi,
You can save COSEM objects to xml (file or OutputStream) using GXDLMSObjectCollection.save method.
JSON is not supported at the moment.

Thank you. I’ll try that

You can use XStream
You can use XStream from ThoughtWorks. You can use it to serialize and deserialize pretty much any Java object to/from XML and JSON.
You can use XStream
Hi,
That is true. We have made own serializer because we must use same xml for several languages, like java, C#, Python, etc. If you are using xml only java apps, you can use what serializer you want to.

Hi Mikko,
Hi Mikko,
As you suggested, I saved COSEM object using GXDLMSObjectCollection.save.
Now I am getting following XML.

The problem with this XML is, I am not able to deserialize it.
Can you please suggest any solution so that I can deserialize the XML into GXDLMSObjectCollection?
