I am trying to convert the XML message to JSON using camel router and save it into a file. Getting the XML message from the source and saving it to destination file etc are working. But when I try to convert to JSON, it did not work. I did not even throw any error/exception in logs. I am running on OSGI container
public class CamelRouter extends RouteBuilder {
#Override
public void configure() throws Exception {
from("file://C:/test/Sample.xml")
.routeId("file-to-file")
.log(LoggingLevel.INFO,"RouteID file-to-file !!!!! starting")
//From XML to JSON
.bean(CamelRouter.class, "convertXmlToJson")
.log(LoggingLevel.INFO,"From XML to JSON !!!!! Done")
.to("file://C:/test/JSONMessages")
.log(LoggingLevel.INFO,"Converted Message Saved successfully");
The bean method to convert XML to JSON convertXmlToJson is shown below
public String convertXmlToJson(String msg) {
log.info("NOW calling JSON conversion");
String jsonStr = null;
log.info("MESSAGE conversion starting : "); //After this message nothing happened
XMLSerializer xmlReader = new XMLSerializer();
log.info("MESSAGE before conversion : " + msg);
jsonStr = xmlReader.read(msg).toString();
log.info("JSON data : " + jsonObj.toString());
return jsonObj.toString();
}
Is anyone know why it is not executing the XMLSerializer portion. I tried this approach because the camel-xmljson's marshal().xmljson() call also give me the same results. Nothing happened after the xmljson() call in my camel routing.
Things that I checked are:
camel-xmljson feature up and running in OSGI
Dependencies mentioned in the Apache XmlJSON website added in my pom file, xom, camel-xmljson etc.
Am I missing anything here? Please help
The problem with your code route is that your bean component handler method resides within your route builder class, plus you invoke the bean component in a way that triggers another instantiation of that route builder class.
Personally, I would move convertXmlToJson to an appropriate utility class. That way you reduce mix of concern in the route builder and the bean component should work fine.
Alternatively, your route might work, if you invoke the bean component like this:
.bean(this, "convertXmlToJson")

We are using the forge-api-java-client. There is an issue in Model Derivatives getManifest call.
The response fails mapping with a single Message String being returned instead of the expected String Array.
Have switched to using local build of the jar, change in file Message.java to include an alternative constructor for the class setMessage
public void setMessage(String message) {
List<String> messages = new ArrayList<>();
messages.add(message);
setMessage(messages);
}
Could this change be merged into the project.
We'll check it, but as of today, that package is just under maintenance. You are welcome to submit a PR.
I am using Xamarin Forms with Newtonsoft.JSON and Xam.Plugin.Settings plugins to save IDevice object as JSON to use it later.
First page:
private async void SelectBluetoothDevice(object sender, SelectedItemChangedEventArgs e)
{
string device = JsonConvert.SerializeObject((IDevice) e.SelectedItem);
AppSettings.AddOrUpdateValue("device", device);
await Navigation.PopAsync();
}
Here I simply make selected item to JSON string and save it. It works like it should be.
But the problem im facing comes whenever I try to deserialize from saved string.
string device = AppSettings.GetValueOrDefault("device", "");
if (!device.Equals(""))
{
Debug.WriteLine(device);
// This line produces error
IDevice dev = JsonConvert.DeserializeObject<IDevice>(device);
settingsDeviceName.Text = dev.Name;
}
Newtonsoft.Json.JsonSerializationException: Could not create an
instance of type Plugin.BLE.Abstractions.Contracts.IDevice. Type is an
interface or abstract class and cannot be instantiated. Path
'BluetoothDevice', line 1, position 19.
So I understand that IDevice is interface and my JSON string cant be deserialized nothing but into object. Any good ideas how to workaround it? Thanks!
This line JsonConvert.DeserializeObject<IDevice>(device); basically does this:
Read the JSON in device
Try to create the type of object you want to deserialize to, in this case, IDevice
Return you the new object with all the properties filled
The problem is with step 2. You can't create an instance of an interface. So you need to deserialize to a concrete object that implements IDevice.
I am passing a json object to the client side from java object with a time and value as attributes with gson
this.template.convertAndSend("/topic/123", gson.toJson(object, type));
and on the client side i have the following code where the json object data is stored in the body of the payload but I am unable to access the properties with obj.time or obj.value, it tells me undefined after it is parsed, I tried showing the entire 'obj' itself and the format seems fine however:
var subscription_callback1 = function(payload) {
var obj = JSON.parse(payload.body);
alert(obj);
};
output with alert(obj)
{"time":"3:00:34","value":"7989797"}
Nevermind solved. Since I am transfering STOMP protocol messages with the Spring 4 framework. I opted to use the Jackson2 message converter instead of directly using gson and it seems to work
#Configuration
#EnableWebSocketMessageBroker
public class MessageBrokerConfigurer extends AbstractWebSocketMessageBrokerConfigurer {
#Override
public boolean configureMessageConverters(List<MessageConverter> messageConverters) {
messageConverters.add(new MappingJackson2MessageConverter());
return true;
}
then i directly put my java object into the send function instead of using gson to convert it as above
this.template.convertAndSend("/topic/123", event)
how can I save a list of Objects to isolatedstorage which is returned from a json call,
I already parse the result into a list of Objects, but I cannot seem to save it, I got a few xmlserialization issues, then I tried following this:
How to save a list of objects in isolated storage in wp7
but it led to a error
{System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: You must implement a default accessor on Newtonsoft.Json.Linq.JObject because it inherits from ICollection.
Opted to do the following:
private static void SerialiseAsJson(string textToSave, string fileName)
{
using (System.IO.StreamWriter file = new System.IO.StreamWriter(#"..\..\NinjectModules\Fakes\FakeData\" + fileName))
{
file.WriteLine(textToSave);
}
}
Usage:
SerialiseAsJson(JsonConvert.SerializeObject([object to serialize]),"filename.JSon");
Would appreciate any code examples of how to call a SpringWS endpoint intrceptor from a Junit test class. Particularly on how to prepare a SOAP message context and endpoint object. The SOAP message in the context will need to have a custom SOAP header included.
Something like....
public class MyInterceptorTest
private static String "... my XML SOAP test message ...";
#Test
public testMyInterceptor() {
myMessageContext = ... Build a MessageContext with the XML message string;
myEndPointObject = ... Build an endpoint object;
boolean result = MyInterceptorClass.handleRequest(myMessageContext, myEndPointObject);
... Check results;
}
Any examples would be appreciated.
The MessageContext can be created by instantiating a DefaultMessageContext object. The request WebServiceMessage can created using the test support class PayloadMessageCreator, but this only appeared in Spring-WS 2.x.
The endpoint object can be anything - it depends what your interceptor does with it. If it doesn't actually use it, then you can just pass in null.
I had the same issue and was able to figure it out in part using #skaffman's suggestion.
Basically, I had a custom EndpointInterceptor that I wanted to test with real data so that I would know I had everything correct.
You will have to upgrade spring-ws-test and other spring-ws dependencies to version 2.0 or higher. I ended up using something different than PayloadMessageCreator.
final Source payload = new StreamSource(new StringReader(soapPayload));
SaajSoapMessageFactory saajSoapMessageFactory = new SaajSoapMessageFactory(MessageFactory.newInstance());
WebServiceMessage requestPayload = new SoapEnvelopeMessageCreator(payload).createMessage(saajSoapMessageFactory);
MessageContext messageContext = new DefaultMessageContext(requestPayload, saajSoapMessageFactory);
soapPayload is the string value of an entire soap envelope.
Something similar to this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
...fill in your custom headers here
</soapenv:Header>
<soapenv:Body><someRequest>...</someRequest></soapenv:Body>
</soapenv:Envelope>
You will obviously need to fill in your request payload, any namespaces, as well as your custom headers.
I set the endpoint object to null as I was not doing anything with it as part of my interceptor.
