selenium-standalone server 2.53.0: HtmlUnitDriver class not found

[Alexhha]

Yes, probably. I think it would be useful to add some warning for windows users, imho.

Anyway, thanks for your help.

java ignores the -cp when you specify -jar, you need to launch it the way the example shows in the README

[Alexhha]

But I want to run in standalone mode, not in Grid. Or the command would be the same?

[lukeis]

then point your "-jar" to the htmlunit-driver-standalone jar file instead?

[lukeis]

and yes, using the -cp way would be the same for non-grid

[Alexhha]

then point your "-jar" to the htmlunit-driver-standalone jar file instead?

I get the following error

# java -jar htmlunit-driver-standalone-2.20.jar
no main manifest attribute, in htmlunit-driver-standalone-2.20.jar

I just want to run selenium server in standalone mode with htmlunit driver support. I'm using codeception framework with the following settings

modules:
    enabled:
        - \Helper\Acceptance
        - WebDriver:
                browser: htmlunit
                url: http://127.0.0.1/
                port: 4444

and yes, using the -cp way would be the same for non-grid

and what class should I use instead of org.openqa.grid.selenium.GridLauncher for standalone mode? As I understand I have to specify fully qualified name of the class from the JAR that has the main(String[]) method

[lukeis]

you use GridLauncher for standalone mode, it's what the selenium-server uses, only if you use the command line argument "-role" will it launch in hub or node mode.

[Alexhha]

I got it. So these commands would have the same "effect"?

# java -jar selenium-2.53.0.jar -Dwebdriver.chrome.driver=chromedriver -host 192.168.127.1 -port 4444

# java -cp "selenium-2.53.0.jar" org.openqa.grid.selenium.GridLauncher -host 192.168.127.1 -port 4444 -Dwebdriver.chrome.driver=chromedriver

[lukeis]

essentially yes... but keep in mind the "-D" parameters should be BEFORE any -jar or classname listed. otherwise they are treated as command line arguments, rather than setting a system property. It works both ways currently in 2.X of selenium... but in 3.X it will not work, and you must specify it early in the command line.

[Alexhha]

Thanks. Will bear in mind

BTW
could add some notice to the example? Because it doesn't work on windows

> java.exe -cp "htmlunit.jar:selenium.jar" org.openqa.grid.selenium.GridLauncher -host 127.0.0.1 -port
 4444 -Dwebdriver.chrome.driver=chromedriver.exe
Error: Could not find or load main class org.openqa.grid.selenium.GridLauncher

You must use semicolon as separator

this is something java specific... on windows it's ";" but on linux/mac it's ":"
