Online PLA

We provide the ability to launch a version of PLA remotely from this web page, if you do not want to install PLA or if you are using a non-supported platform. The launcher allows you to select one of five PL models:

The current version is version 5.3 (2017-04-24).

You can access the PLA Launcher, which will run by talking to our server at SRI, in one of two ways. You can download the client or you can use Java's webstart to achieve the same effect (if webstart works for you). Webstart comes with a myriad of security hurdles that may be too daunting, which is why we provide the alternative route. The webstart approach seems to work for Windows and Linux (at least Java 1.6 or higher is your best bet here). There are problems with webstart on Mac OS X, and the safest route may be to download the PLA Client (see below). Always trust option or else it will quietly fail.

Webstart Version

To use the webstart version of the PLA Launcher:

Downloadable PLA Client

To sidestep the webstart infrastructure, simply download and if your browser doesn't unzip it, you'll need to do this too. Assuming you have put the zip on your Desktop:
[iop@serrano ~/Desktop]$ unzip 
  creating: PLALauncher/
  inflating: PLALauncher/launcher
  inflating: PLALauncher/lib/online.jar    
  inflating: PLALauncher/lib/iop.jar       
[iop@serrano ~/Desktop]$ 
or if it went into your Downloads folder on a Mac, just click on the icon and drag the PLALauncher folder onto the Desktop. Now cd into that directory and execute the launcher script. You can also just open the folder and double click on the launcher too.
[iop@serrano PLALauncher]$ ./launcher
You may need to temporarily modify your security settings on the Mac to be able to use the launcher, but thats just a sign of the times, unfortunately. On windows you may have to rename the launcher file to, then you should be able to launch it by clicking (assuming Oracle's java is in your PATH).
