In my case i am using the asa_samples.js aggregator provided by WebSphere Portal.
Once the asa aggregation is enabled and if you did not change the URL where the data should get submitted then it will "ASA Tracking image" text at the end of the page like this
In my case i changed the value of
trackingImgin the asa_sample.js like this
var trackingImg = "http://localhost:10039/trackingservlet/tracking.gif";
I am planning to create my own trackingServlet that will be deployed in the same portal server. After i made this change i can see that the portal is submitting data to the servlet like this
I dont have the trackingServlet ready yet so its getting HTTP 404 error.
It seems that the THeme structure is changed completely in the WPS 70 and we are supposed to use WebDav for making theme changes, but i am not able to use WebDav for connecting to portal, so i searched for where is asa_samples.js and it seems that the portal keeps copy of it in
WebSphere\wp_profile\temp\wpnotes\WebSphere_Portal\JCRFileStore\filestore\fs-type1\themes\PageBuilder2\jsfolder like this. I changed that file directly and it worked
