Hallo, 

we in our company use GWT quite extensively and up until now for our Web Applications exclusively. We are basically a Java shop and using GWT, we can concentrate on the important stuff ;-) 

Now we are starting with a new Project: a centric company specific Web Map Component, which is Application Domain aware and which can be used in different applications of our company, also can also be used in a "pure" Html Szenario.... Basically it will be a "small" application specific layer based on  a existing opensource Map library. Candidates are OpenLayers2 and Leaflet. Both Java Script Libraries. Although we hav'nt decided yet, we dread getting to deeply "sucked in" by Java Script developement. So we are thinking about using GwtExporter. Basically writing our company specific Library with GWT using JSNI to integrate either of the Opensource Libraries. And for JS usage szenarios use GwtExporter.


Does this approach make sense : GWT Wrapper around a JS Library, which is made avaible for an out GWT Context usage via GwtExporter? 

Or should we  better wait for Gwt Js Interop in GWT 3.0?  It seems that 2.7.0 already has experimental support for Js Interop? So we could start experimenting?


Or write our wrapper in JS .... which we really would prefer not to do....


Any thoughts , feedback , recommendation, experiences are greatly appreciated.......

Christoph

Hi Christoph,

before proceeding, I would recommend you have a look at the Geomajas project (www.geomajas.org), as it is a web mapping framework built using GWT & Java. It might just be what you are looking for.

Cheers,

Hi Pieter, 

we actually built a prototype with based on Geomajas ;-) ... but i was'nt aware that Geomajas can be also used in a JS Scenario? 

Best Christoph

Christoph,

the reason I am on this mailing list, is because I did some tests trying to export the Geomajas GWT code to a Javascript version using GWT exporter.
This code is also available in the Geomajas project. Perhaps it could help you out in some way. (link to the showcase: http://dev.geomajas.org/showcase-javascript/)

Cheers,

Pieter De Graef
