HELP (about running RLVizApp)

[Qing Da]

Hi, all

     Sorry to bother you, but I really need your help about running the RLVizApp program. 

     I did the exact procedures following http://library.rl-community.org/wiki/Graphical_Experiments_RL_Viz_Tutorial, and had put the MountainCar.jar and RandomAgent.jar into the 'products' directory,  but when I executed 'bash run.bash'  (ubuntu 12, openjdk 7), I met those exceptions:

Exception when trying to look up values from the manifest of Jar which created class: class org.rlcommunity.rlviz.agentshell.AgentShell

java.util.zip.ZipException: error in opening zip file

at java.util.zip.ZipFile.open(Native Method)

     I didn't changed any code, and couldn't figure out why this happened. I have no idea what to do next and I hope I can getyour help. Thanks!

Qing,

I'm not familiar with your specific problem, but here's a quick thing
to try. I've attached a quick installation script that I've used for
my own installations on multiple computers. In my experience, all you
have to do is

1) run the script in [installation_directory],
2) add "[installation_directory]/rlglue-3.04/java-codec/JavaRLGlueCodec.jar"
to your Java classpath,
3) and execute "bash run.bash" in
"[installation_directory]/rlglue-3.04/rl-library/SampleExperimentRLVizApp-Java-R1207".

If you try it out, I'd do so in a different directory than the one
your current installation is in.

Best of luck,
Brad

Good to hear!

I should add that the script basically just follows the instructions
from the RL-Library download website. For example, you can see the
commands for Mountain Car here:
http://code.google.com/p/rl-library/wiki/MountainCarJava. To add
domains/agents to the script, just pattern-match.
