Use javascriptsupport.require.with() directly with Jackson
Hi guys, I'm trying to use Jackson directly with
javascriptsupport.require.with() like so
ObjectMapper mapper = new ObjectMapper();ObjectNode node =
mapper.valueToTree(pojo);
javascriptsupport.require.with(node);
However I get the following exception
JSONObject properties may be one of Boolean, Number, String,
org.apache.tapestry5.json.JSONArray, org.apache.tapestry5.json.JSONLiteral,
org.apache.tapestry5.json.JSONObject,
org.apache.tapestry5.json.JSONObject$Null,
org.apache.tapestry5.json.JSONString. Type
org.codehaus.jackson.node.ObjectNode is not allowed. -
I can't seem to find the API on require, does anybody know how I could use
jackson directly without having to first convert my Jackson object to a
string and then pass it into JSONObject?
Thanks,

In this case, I think you'll need to write a Tapestry JSONObject mapping
for Jackson if someone else didn't do it in an open source project yet.

Yes serverside and Jackson will convert java objects to json and I'm trying
to pass the generated json object to clientside. I'm building a custom
implementation of modal and I'm looking to pass a JSONObject into
javascriptsupport.require.with(); This works fine if I convert the
generated json into a string then pass it into the JSONObject() like so
public JSONObject toJSON() throws IOException {
ObjectMapper mapper = new ObjectMapper();
return new JSONObject(mapper.writeValueAsString(new
Warnings(warnings)));
}
javaScriptSupport.require("warnings-modal-dialog").with(storage.getWarning().toJSON());
however that is very inefficient and if I try to do it as followed I get
the below exception
ObjectMapper mapper = new ObjectMapper();ObjectNode node =
mapper.valueToTree(pojo);
javascriptsupport.require.with(node);
JSONObject properties may be one of Boolean, Number,
String,org.apache.tapestry5.json.
JSONArray, org.apache.tapestry5.json.JSONLiteral,
I was thinking Jackson could build a json object ready to be passed to the
clientside without having to first convert it to a string then pass it into
my JSONObject. I'm trying to avoid the last two steps.

I'm very confused as to what you're trying to achieve. This is server-side, yeah? Isn't Jackson's purpose to convert between Java objects and JSON? Are you wanting to pass JSON to client-side? What's the name of the client-side JavaScript module? Does it expect parameter(s)? What type? (You can pass JSONObject, Boolean, Number, String, JSONArray, JSONLiteral, JSONObject, JSONString, as the exception message says.) How will you convert from Jackson's output to one of those types? Maybe you could use ObjectMapper#writeValue(...) as input to JSONLiteral, pass it to the client-side, and the module could parse it to JSON?
JavaScriptSupport#require(String moduleName) returns an Initialization.
Initialization#with(Object... arguments) expects the types noted above. The number of args has to match the number of args client-side.
See http://people.apache.org/~hlship/t5api/apidocs/org/apache/tapestry5/services/javascript/JavaScriptSupport.html#require(java.lang.String)
But all of this begs the question, is this heading in the right direction?
HTH,
Geoff
