Java Web Start Troubleshooting

Java Web Start works smoothly for most users, still the following sections address some issues that may possibly arise. Let us know if you encounter any problems.

What is Java Web Start?

Java Web Start provides a platform-independent and secure deployment technology. It allows users to start Java applications from a web server. Java Web Start works with any browser. It also makes sure that the application is always on the latest version.

Requirements

The latest version of Java needs to be installed.

Can't start application

Most probably your browser is not set up in a way so it knows to send the Java Web Start files (.jnlp) to the Web Start application. Some of the operating system specific tips are listed below.

My browser displays the .jnlp file as text

Your browser or system is not set up correctly to send .jnlp files to Java Web Start. Make sure you have Java installed.
Linux
OSX

My Java version is too old

Make sure you have the latest version of Java installed (see above).

Java Web Start will launch, but returns an error or runs poorly

Our 3D viewers require 3D graphics support. Often out of date or missing video card drivers will prevent the applications from starting or running correctly. To resolve this simply update your video card drivers.

The application wants unrestricted access to my system

All of the web start applications launched from RCSB are downloading PDB files if required. This is technically only possible if you give the application permission to access your system resources. We guarantee that the Java Web Start applications signed by our RCSB digital signature and downloaded from our web site:

Opening .jnlp window is displayed

When you try to start an application, a window pops up. Your browsers asks you what to do with the file.

I am using a Proxy for internet connection. Will it work?

Java Web Start should pick up the proxy setting from your browser automatically. Depending on your operating system, your Java Web Start application can contain configuration for proxies as well. Make sure your browser and WebStart are using the same settings. To launch the web start user interface, type javaws.
