Polyline feature layer from JSON

[AndrzejMilosz]

In my application I want to create a polyline feature layer from this JSON file: http://ibikekrakow.com/wp-content/themes/bike/js/green.js Is this file good for this?
I found an example how to create a feature layer from points: http://gis.stackexchange.com/questions/8896/feature-layer-with-ondemand-mode/8912#8912
What is different in creating a polyline layer?

You can do the same thing with lines, just need to tweak the JSON you pass to the feature layer constructor.

Since your source file is GeoJson, you need to convert to the esri json format as well. I used this:  https://github.com/Esri/geojson-utils

Here's a working example:  http://jsfiddle.net/ZdLF7/

Note that I included the GeoJson converter JS directly from github. If you use that code to convert your GeoJson you should download and host that .js file yourself.

That works, thank you!
Is there a possibility to save this feature layer (created from JSON) in ArcGIS geodatabase?
