JavaBridge - Probably php was not installed as "/usr/bin/php-cgi" or "c:/php/php-cgi.exe"

Question

I am trying to setup a JavaBridge between my Java-application and Apache/PHP application. First I tried through CLI =>

MacBook-Pro:php-java-bridge_5-2 username$ java -classpath JavaBridge.war TestInstallation
Starting a simple servlet engine: [/Library/Java/JavaVirtualMachines/jdk1.8.0_92.jdk/Contents/Home/jre/bin/java, -jar, /Users/username/Downloads/php-java-bridge_5-2/ext/JavaBridge.jar, SERVLET_LOCAL:8081]

java.lang.RuntimeException: Could not run PHP ([php-cgi, -n, -d, allow_url_include=On, /Users/username/Downloads/php-java-bridge_5-2/test.php]), please check if php-cgi is in the path.

This seemed without success so I tried another option; I installed TomCat with Apache Mamp. The installation went well and I deployed the JavaBridge.

Unfortunately when trying to accessing it, I receive a similar error as when I was trying to run it throughout the CLI.

HTTP Status 500 - An IO exception occured. Probably php was not installed as "/usr/bin/php-cgi" or "c:/php/php-cgi.exe"

type Exception report

At the moment I am out of inspiration of solving this problem, any advice?
