I was able to run a compiled jar if I set the ruby version to jruby via RVM. But I don't know why things are behaving that way.. The same issue was discussed for a bit in this thread: http://code.google.com/p/selenium/issues/detail?id=2940 . Apparently it's an issue with jruby or warbler..

it seems that its a rubyzip issue....

any update on this issue?

have the same problem, when running via jruby it works, the JAR works in my mac notebook, but not in the linux server (centOS 7), same error as above.

I've checked this yesterday, and that's what I could understand:

1. the zipper method in firefox lib is expecting a file, and gets a stream, in the jar the file is not decompressed into the filesystem as the war does (not a java programmer, so forgive any wrong assumptions).

2. The error occurs when trying to fetch webdriver.xpi to create a default profile. I did not spent too much time on the selenium classes, but my monkey patch was to change the constant in firefox lib ( WEBDRIVER_EXTENSION_PATH in firefox/profile.rb ) to point to some place outside the jar path (that java recognizes as ClassName.jar!/gems/something), like in the same folder as the jar lives.

3. Without selenium that happens, using just rubyzip to unzip a file but sending a stream.

Hope that helps, thanks.
