In my current project, we have a Credit Card form page which is called from a different calling application. The calling application submits the form at their side and the Credit Card page is loaded. Now as a requirement, we need to follow the same procedure except when the calling application submits the form, the Credit Card page should come as pop up with the current page becoming translucent.I know this is easy when we are dealing with same JVM.But here the calling application is in a different JVM and the Credit Card application in a different. Also, when the calling application form submits, the page will get refreshed. How can I get the same page from where the calling application submits with the Credit Card page as pop up and the submitting page becoming translucent. If possible, please provide solution so that calling application don't have to make any changes. I want to change only the Credit Card application.
