When you click on the lobby link your computer downloads a file named "vmtClient.jnlp",
which needs to be run by Java Web Start to get you to the VMT lobby room.
If you have just installed Java Runtime Environment (JRE) to your machine, then your
computer might need your assistance to pick a program to open it. If that is the case
and you are using a Windows machine, then you can do the following to solve this
problem:
1. Download the file to your desktop (right click on this link, and choose "save target as"). You will see an icon on your desktop similar to the one shown below. (in this
example the file is associated with note pad by default)
2. We need to tell Windows which program it should use to run this file. To do that
right click on the icon, and select "Properties". You will see a window similar to the
one below:
3. Right next to the "Opens with" field you should see a button with label
"Change...". Click on this button. This will open another window (shown below)
4. If you can see jawaws (stands for java web start) among recommended
programs then click on it, and then press the OK button. Proceed to step 5.
4.1 If you cannot see jawaws as an option, then you should click on
"Browse...". This will open a new window as shown below
4.2. You should be looking at the contents of your Program Files folder here,
which is the default folder Java Web Start should be installed. Locate the folder
named Java Web Start among the list shown above, and double click on it. You
will see the contents of that folder (as shown below)
4.3. Double click on jawaws.exe (as shown above).
5. Now the properties window we opened at step 1 should look like this
Click OK to close this window.
7. Now the icon on your desktop should look like this
Double click on this file. This should now start Java Web Start and you should be
able to see the Lobby window shortly.
