I found a way to do it.
You need first to download JavaBridge.war
Then you import it as a Java application in Tomcat.
Then you install a MAMP module such as LimeSurvey or Gallery, like I did.
You make a symbolic link between your apache application module to your Tomcat webapps folder.
In your Tomcat web apps folder look for the folder named JavaBridgeTemplate621 and copy all the files inside to your apache application module folder.
To start them, the link in Tomcat will not work, you have to add htdocs at the end of the URL as this
