In control pannel win - 7 when I open java in control panel in advanced, Default Java browsers, Microsoft internet explore is ticked and grayed out, and I am not able to check / uncheck that box. And internet explorer - tools - options - advanced - Java portion is not coming.
I tried lot, uninstalling java, and re-instaling, even I tried un-installeing internet explorer and re-insall etc. Java is not registering in internet explorer.
I tried both for 32 bit and 64 bit both java and internet explorer.
JSP doesn't have anything to do with Java installed on the client side. When you say it's not opening, what exactly do you mean? What URL are you using and what exact error/exception are you seeing? What server are you using to deploy the JSP application?
Client-side Java has nothing to do with JSP-based Java web applications. You don't even need the JRE installed on the client to run a JSP application. The Java web app uses a JVM on the server and doesn't send anything to the client except plain HTML. You need to give us more specifics about the error you are seeing and forget about the JRE on the client. It's not part of the issue.
