Can you provide some more details (or paste code snippets) on how you're using it in JDev?
And which JDev version?
I am using ADF Faces/dvt and my JDeveloper version is 22.214.171.124.0
You need a more recent JDev version (like 11.1.2.x.x or later).
DVT Geomap (if that's what you're using) includes a local copy of oraclemaps.js.
That needs to be a more recent version.
Issue is solved after creating the web page using latest JDeveloper (126.96.36.199). Thanks a lot for your help
