installing a package thro java

[rgsiva]

Hi In my project I am developing a web page which fetches the details like application name,directory in which it is to be installed ,and submits the request to the servlet.The servlet has to install the package automatically on the system(without user double-clicking the exe).Is it possible with java?How?.Can I able to simulate the double-clicking of the application package to start installation atleast. Please help me Thanks in advance sivanantham
