The implementation of all these examples and code snippets can be found in my GitHub project – this is an Eclipse based project, so it should be easy to import and run as it is.
If you have a few years of Linux experience, and you're interested in sharing that with the community (and getting paid for your work of course), have a look at the "Write for Us" page. Cheers. Eugen
How about Streaming with Jackson API. Can you show an example of extracting an array from JSON format: { “type”: “FeatureCollection”, “crs”: { “type”: “name”, “properties”: { “name”: “urn:ogc:def:crs:OGC:1.3:CRS84” } }, “features”: [ { “type”: “Feature”, “geometry”: { “type”: “MultiPolygon”, “coordinates”: [ [ [ [ -69.996937628999916, 12.577582098000036 ], [ -69.936390753999945, 12.531724351000051 ], [ -69.924672003999945, 12.519232489000046 ], [ -69.915760870999918, 12.497015692000076 ], [ -69.880197719999842, 12.453558661000045 ], [ -69.876820441999939, 12.427394924000097 ], [ -69.888091600999928, 12.417669989000046 ], [ -69.908802863999938, 12.417792059000107 ], [ -69.930531378999888, 12.425970770000035 ], [ -69.945139126999919, 12.44037506700009 ], [ -69.924672003999945, 12.44037506700009 ], [ -69.924672003999945, 12.447211005000014 ], [ -69.958566860999923, 12.463202216000099 ], [ -70.027658657999922, 12.522935289000088 ],… Read more »
Hey Tariq,
That might be an interesting topic for an article. My suggestion – if you need to have a quicker answer – have a proper test that can be used to reproduce what you’re trying to achieve – and email me the details. I’d be happy to have a look. Cheers,
Eugen.
Hi Eugen, I have been trying to code a servlet for a while that binds remote mysql to a jquery grid, with no success. Is there any chance you might have a look, the JSON string generates but the binding fails in the xhtml view.
