Re: How to best get data into a GWT app?

I've read that tutorial. It rather deals with getting data cross-site. My question is how do I get my hands on a Javascript-Object defined on the website from inside GWT? Once I have that object I can do the rest myself.

You should use JSNI interface for that.

Thanks. Reading the Dictionary JavaDoc I thought this is the solution.

The problem is my JSON data string has an array with objects inside:

var CurrentTheme = {    highlightColor: "#FFFFFF",    shadowColor: "#808080",    data: [{}, {}, {}]
 };

calling dictionary.get("highlightColor") works great but when I want to get the string that makes up my data array it returns: [object Object],[object Object],[object Object], ... etc ... ]

I guess I could work around this by escaping the data-array and thus turn it into a string. Or is there a better solution?

I also need to add a module <inherits name="com.google.gwt.i18n.I18N"/> I otherwise do not use if I want to use Dictionary.

I am wondering if there is perhaps some other way then Dictionary to easily get a simple JSON-string into GWT without importing another module, writing JSNI or escaping the JSON string?


Thanks,
Carsten

One easy way would be to use the Dictionary object in GWT if you just have and associative array of key/value pairs. See the example code in the JavaDoc.
