Is it possible to fire Java methods from Jena SWRL Rules

I am working on a Performance analysis on Ontology based Context Management and Process based Context Management. However, in order to create a similar scenario with the PCM case study, I am required to fire Java methods directly from Jena SWRL Rules during reasoning. I have made a lot of research to no avail but my professor claims i开发者_如何学运维t is possible with Jena. For Example,

Forward(vpnAccess)<--hasChain(vpnAccess,Forward)^
                     hasExternalInterface(vpnAccess,eth1)^
                     hasSrcIP(vpnAccess,ip4.3.2.1)^
                     hasDstIP(vpnAccess,ip1.2.3.4)^
                     hasProtocol(vpnAccess,tcp)^
                     hasDstPort(vpnAccess,portVPN)^
                     hasTarget(vpnAccess,acceept)

 Where Forward is a java class method:
    public static void Forward(String eth1,String Chain,Ip SrcIpAddr,Ip DestIpAddr,.. )
                      {......
                         .......}

There is a brief tutorial on using "Pellet + OWLAPI + SWRL Rules" you can read it.
