i'm using phantom.js driver selenium in java code. it's large project i'll copy think relevant code.

i had working fine firefox driver.

i instantiate here:

     capabilities caps = new desiredcapabilities();                 ((desiredcapabilities) caps).setjavascriptenabled(true);                 ((desiredcapabilities) caps).setcapability("takesscreenshot", true);                 ((desiredcapabilities) caps).setcapability("timeoutinseconds", 20);                 ((desiredcapabilities) caps).setcapability(                         phantomjsdriverservice.phantomjs_executable_path_property,                         "/applications/phantomjs-2.0.0-macosx/bin/phantomjs"                 );                 webdriver driver = new phantomjsdriver(caps);  driver.get(base_url+searchquery.urlstring());
