finally took some time to figure out the problem
if you are using netbeans and you get a "file not found" error when you try to open a jsp file this can be resolved checking your proxy settings on your IDE
When you set the IDE to use a proxy, your Internet browser may attempt to route all files through the proxy, including local files. This results in a File Not Found error when you try to open an HTML file or applet in the IDE's external browser. To resolve this problem, add localhost and your machine name to the list of bypassed hosts in your browser's proxy settings.
