I have installed the JavaScript API locally to use in a developer environment with no internet connection. The issue I am encountering is when I attempt to view the sample service hosted by ArcServer I am presented with a blank white page. The sample service is visible when viewed in Desktop & Catalog so I presume the issue is related to my installing of the JavaScript API and setting it for local use. I believe I followed the windows install notes for JavaScript 3.15 to the letter using the Normal build.
- I extracted and copied
<SPAN style="font-size: 10.0pt;">\arcgis_js_api\library to the C:\Inetpub\wwwroot folder.</SPAN> <SPAN style="font-size: 10.0pt;"><SPAN>I opened init.js & dodo.js and replaced both [HOSTNAME_AND_PATH_TO_JSAPI] with mysitehere/arcgis_js_api/library/3.15/3.15/ (did not include </SPAN><A class="jive-link-external-small" href="https://community.esri.com/external-link.jspa?url=http%3A%2F%2F" target="_blank">http://</A><SPAN>)</SPAN></SPAN><SPAN style="font-size: 10.0pt;">I successfully tested </SPAN>http://mysitehere/arcgis_js_api/library/3.15/3.15/init.js and was prompted with init.js opening.

I am unable to replicate the next step of validating the JSAPI library install using the sample service when accessing it with http://.

I continue with the installation document and change the ArcGIS Services Directory “View In JavaScript” URL to the ones in the document

Lastly I copied the following code to the <ArcGIS Server Install Location>ArcGIS\Server\framework\runtime\tomcat\webapps\arcgis#rest\www\client\mapserver\mapserverJSAPI.jsp file
<style>
@import "<%=jsapiArcgisCssUrl%>";
@import "<%=cpath%>/static/jsapi.css";
@import "<%=jsapiArcgisUrl%>/js/esri/css/esri.css";
</style>
This is my first attempt at attempting to setup a developer environment and any help is greatly appreciative in determining what I am doing wrong. Thank you.
