Adding data to Meteor from Java

I'm using Java DDPClient (https://github.com/kutrumbo/java-ddp-client) and I am trying to insert data into a meteor application.

I do this from java:

    DdpClient client;
    try {
        client = new DdpClient("localhost", 3000);
        client.addObserver(this);
        client.connect();
        Object[] objArray = new Object[1];
        objArray[0] = new String("{name:'peter andersson', phone:'12345678'}");
        client.call("createNewCustomer", objArray);
    } catch (URISyntaxException e) {
        e.printStackTrace();
    } catch (Exception ex) {
        System.out.println("Exception:" + ex.getLocalizedMessage());
    }

and this in Meteor (collection Customers) 

Meteor.methods({
    "createNewCustomer" : function(options) {
      var ret = {};
      options.replace(/(\b[^:]+):'([^']+)'/g, function ($0, param, value)      {
      ret[param] = value;
    });
    Customers.insert(ret);
  }
});

It works, however it seems like unnecessary work to code it into a string and then decode it to a javascript hashmap.

I have tried creating an array of Objects (Strings) but no matter how I do it it doesnt work as expected.

What's the "proper" way of doing it?

EDIT:

My wish is that the Meteor code would look like this:

Meteor.methods({
    "createNewCustomer" : function(options) {
      Customers.insert(options);
    }
});

I guess what I want to know is how to send from Java (using Java DDP Client) so that no decoding is necessary in Meteor.

Proper way would be to decode the string using JSON.parse(). Just make sure that string is valid JSON document.

in your java code change it to:

objArray[0] = new String("{\"name\":\"peter andersson\", \"phone\":\"12345678\"}");

and in your javascript code should now look like this:

Meteor.methods({
  "createNewCustomer" : function(options) {
    var ret = JSON.parse(options);             
    Customers.insert(ret);
  }
});

p.s. Also in your java code you might look into possibility to construct JSON string using some JSON library, if you want to do it dynamically.
