I did some note about the Java Web Start Security as below, do you think if that is completed? Thanks
In Java Web Start all applications are (by default) launched in a secure "sandbox."
Applications have restricted access to local computing resources such as the disk and network, by default.
Java Web Start provides secure APIs that allows an application to import and export files from the local disk under the users control.
How can I enable my application to gain unrestricted access to the system? After the user has accepted the certificate.
