com.aimmac23.node.servlet.VideoRecordingControlServlet cannot be instantiated

[haonumen]

I got an error when start chrome with video-node.

The specified class : com.aimmac23.node.servlet.VideoRecordingControlServlet cannot be instantiated com.aimmac23.node.servlet.VideoRecordingControlServlet

and I saw in your documents 👍

Node setup

A Selenium node can be launched by running:

java -cp selenium-video-node-2.0.jar:selenium-server-standalone-3.0.1.jar org.openqa.grid.selenium.GridLauncherV3 -servlets com.aimmac23.node.servlet.VideoRecordingControlServlet -proxy com.aimmac23.hub.proxy.VideoProxy -role wd

I have already do that ,but I ran it in linux with xvfb.

my startup for xvfb is: xvfb-run -n $SERVERNUM --server-args="-screen 0 $GEOMETRY -wr"

and saw your document is: xvfb-run -a -s "-screen 0 1280x1024x24 -wr" 'video node start command>`

what does <video node start command> mean? should I append them in my command line?

[haonumen]

why video node start command is not displayed?

Hi haonumen,

For the first error, I would recommend that you have the JAR name of the video node correct. Java doesn't tell you if the JAR file doesn't exist - it simply tries to proceed anyway (See Issue #31 ).

<video node start command> means you have to substitute in the previous line - "java -cp selenium-video-node-2.0.jar...". This convention is used by a lot of other command-line documentation systems (like man pages).

Let me know if you have any more problems,
