Hi all,
I have REST service with JSON as input message. I want in JCN to convert that input JSON message into Java object, something like JAXB for XML messages.
Let's say that my input message looks like this:
| Code: |
{
"request": {
"id": 123,
"name": "John",
"mail": "john@example.com"
}
} |
and I have class Request that has fields id,name and mail. Is it possible to convert(unmarshal) this JSON to java object Request? Can someone help me how to do this? |

This is not really an IIB question - it's a Java programming question.
Most people on this forum will advise you to
-use the JSON parser that comes with IIB
- process the message tree using ESQL or the Mapping node.
Do you have a special reason for wanting to create a Java object? |

| You could pass your JSON message into a JCN, instantiate your "Request" class, set the fields using the data from the input message and then serialise the object and pass it along as a BLOB to whatever node will send it to the Java program that will deserialise it. This assumes your class has implemented Serializable. |
