Hi Max,<div><br></div><div>I just reread your error message. It looks like mod_python cannot find the handler 'startmod'. It was probably not added to your python path correctly. Double check your /etc/ros/ros_webui_appache.cfg file. It should look something like this:</div>

<div><br></div><div>As for using the WebUI, it is a very large program and I wouldn't try editing it directly. Willow Garage has set up "Apps" that you can make for the WebUI. How these apps work is undocumented right now, I found out how to use them by talking to them at the PR2 workshop. Later today I will try and write some getting started info. As long as you keep to just modifying and creating Apps, the learning curve for using WebUI isn't too bad. You don't really need to know much about Clearsilver. It is just a templating library that they use to mash up their javascript and html easily from python. Just reading through ClearSilver their tutorial so that you recognize clearsilver's syntax should be fine. </div>

Hi Max,
<div><br>
</div>
<div>Are you trying to get the webui running on a PR2 or simply on another computer with ROS installed?</div>
<div><br>
</div>
<div>With the pr2, it just just be set up automatically with the deb files. If not, double check that your pr2-environment is installed. <br>
<br>
With another computer, following these instructions work:<a href="http://www.ros.org/wiki/webui" target="_blank"> http://www.ros.org/wiki/webui</a>. However, you need to launch two nodes, rosweb and launchman (both are in the web_interface stack) yourself every time you want to use it. <br>
<br>
<br>
</div>
<div>Regards,</div>
