How to pass JSON in Open ESB

Question

I am creating a simple OpenESB application. On left I have a rest inbound partner link and on the right I am calling a rest outbound partner link. I am trying to pass json to the service but openESB automatically parses it and converts it into XML.

So the question is how do I stop open esb from converting the json string into xml since the service doesn't accept xml input.

Answer 1

OpenESB can process XML only.

For consume-types=[ "application/json" ] JSON input is automatically converted into XML for further processing and invoke any external partner links if required.

For produce-types=[ "application/json" ] XML data is converted into JSON by OpenESB.

To achieve the same your JSON has to be in a format that when converted to XML, produces valid XML. For example, {"name":äbc"} looks like <name>abc</name> when converted to XML.

JSON input like,

{
    "name1":äbc",
    "name2":äbc"
}

looks like

<name1>abc</name1>
<name2>abc</name2>

Now name1 and name2 XML elements does not have root element so OpenESB can not process it.

If you give JSON input as

{
     "someRootElement":{
         "name1":äbc",
         "name2":äbc"
      }
}

, converted XML would be like,

<someRootElement>
   <name1>abc</name1>
   <name2>abc</name2>
</someRootElement>

This should work in your case. :)
