Java Web Start hangs on download dialog. What do I do?

To make sure Java Web Start is set up to access the switch in the same way your browser is set up, follow

these steps:

Step 1 Start up Java Web Start (javaws.exe/javaws). You see the Java Web Start Application Manager.

Step 2 Choose File > Preferences > General and make sure your proxy settings are correct. For example, if

you are using an HTTP proxy, set it up here.

Step 3 Check Use Browser.

For browsers like Opera, certain versions of Mozilla, or Konqueror, you must manually register Java Web

Start as the helper application for the JNLP files. To do this, the data you need is:

•Description=Java Web Start

•File Extension=jnlp

•Mime Type=application/x-java-jnlp-file

•Application=path-to-javaws (e.g. /usr/local/javaws/javaws)

After setting this up, you may need to restart the browser. If you see "Java Web Start not detected"

warnings, you can ignore them. These warnings are based on JavaScript, and not all browsers behave

well with JavaScript. Click on the install links to install Fabric Manager or Device Manager.

Note For Windows Users: To set up Java Web Start on *.jnlp files, select Windows Explorer > Tools > Folder

Options > File Types. Either change the existing setting for JNLP or add one so that *.jnlp files are

opened by javaws.exe. This executable is under Program Files\Java Web Start

If you cannot get your browser to run Java Web Start, you can still run Java Web Start from the command

line (javaws.exe or javaws) giving it the URL of the Fabric Manager or Device Manager on the switch

as an argument. For example, if your switch IP address is 10.0.0.1, you would use these commands to

start Fabric Manager and Device Manager:

javaws http://10.0.0.1/cgi-bin/fabric-manager.jnlp

javaws http://10.0.0.1/cgi-bin/element-manager.jnlp

Be sure you have Service Pack 3 installed if you are using JRE 1.4.1. (You should actually have been

prompted to install Service Pack 3 during the JRE 1.4.1 installation.) If you do not have it installed,

Windows 2000 may crash. If you do not want to upgrade to Service Pack 3, you can install JRE 1.4.0.
