How to use phantomjs.binary.path when PhantomJS is embedded inside a jar file?

Question

I am using phantomjs for headless browser testing. I call phantomjs from within my java file (MainTest.java). The code runs fine in my local machine. I bundle both the phantomjs.exe and the calling java file inside a jar file (tetsPhantom.jar).

• testPhantom.jar
  • phantomjs.exe
  • MainTest.java

On the server, it is failing when it tries to find the phantomjs executable path:

String webDir = LiExportEmails.class.getProtectionDomain().getCodeSource().getLocation().toExternalForm(); // Returns http://myservername.com:8080/testPhatom.jar
System.setProperty("phantomjs.binary.path", webDir);

I have tried setting it to http://myservername.com:8080/testPhatom.jar!phantomjs.exe as well, but it still fails.

What should be the correct path of phantomjs located inside the same jar file as the caller?

Solved it by using the approach from JNLP Webstart Launch Issue and Copying a binary file outside of a jar , with one change:

File f = new File ("./phantomjs.exe");
if (!f.exists()) {
  InputStream in = Myclass.class.getClassLoader().getResourceAsStream("phantomjs.exe");
  OutputStream out = new FileOutputStream("./phantomjs.exe");
  IOUtils.copy(in, out);
}
System.setProperty("phantomjs.binary.path","./phantomjs.exe");
