[Php-java-bridge-users] NoClassDefFoundError

When Tomcat  starts I got an error msg showing JavaBridge was not loaded. Would someone help to find the cause?

Accessing http://localhost:8080 I get TOmcat homepage, but http://localhost:8080/JavaBridge/ gives me 404 / The requested resource () is not available.

When I run "java -jar JavaBridge.jar SERVLET:8080 3 javabridge_servlet.log" everything works fine, but I can't get it to work with Tomcat.
May be it's related o Tomcat's permissions, but I'm not sure which settings to change. I already inserted in catalina.policy:
grant codeBase "file:${catalina.home}/webapps/JavaBridge/WEB-INF/lib/-" {
    permission java.security.AllPermission;
 };
with no success, no matter if I start tomcat with or without "-security" parameter


Any clue?
