Call an RFC from a Bean Class

Question

Hi,
My question is how to call an RFC from a bean Class (stateless Session Bean). I have followed a link and wrote a following class :
public class Bapi1
     public static void main(String args[])throws ApplicationFaultException, SystemFaultException 
     String aMonth[] = null;
     String aMonthVal[] = null;
     JCO.Client jcoclient = null;
               Yfunc001_Output output = null;
               try {
                    jcoclient = JCO.createClient("Client","Username","Password","Lang","SAP Application System"," SAP System Number");     
                    try {
                         jcoclient.connect();
                         System.out.println(""+ jcoclient.getASHost()+ jcoclient.getClient()+ jcoclient.getLanguage()+ jcoclient.getSystemNumber()jcoclient.getUser()jcoclient.isValid());
                    } catch (RuntimeException e2) {
                         // TODO Auto-generated catch block
                         e2.printStackTrace();
               } catch (Exception e) {
                    // TODO Auto-generated catch block
                    System.out.println(e.getLocalizedMessage());               
                    e.printStackTrace();
               Yfunc001_Input input = new Yfunc001_Input();
               Graph_PortType mytype = new Graph_PortType();
               mytype.messageSpecifier.setJcoClient(jcoclient);
               try {
                    output =  mytype.yfunc001(input);
               } catch (SystemFaultException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
               } catch (ApplicationFaultException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
               jcoclient.disconnect();
               YstructType_List list = output.get_as_listItab();
               int listsize = list.size();
               for (int i = 0; i < listsize; i++) {
                 YstructType elem = list.getYstructType(i);
                                        aMonth<i> = elem.getMth();
                                      aMonthVal<i> = elem.getMval();
When I try to Execute this class I get the following Exception
java.lang.NoClassDefFoundError
*     at com.sap.mw.jco.MiddlewareJRfc$Client.connect(MiddlewareJRfc.java:882)*
*     at com.sap.mw.jco.JCO$Client.connect(JCO.java:3159)*
*     at com.ltil.fusionejb.Bapi1.main(Bapi1.java:32)*
Exception in thread "main"
I get an Error on Line : jcoclient.connect();
What All libraries I need to install? Please List down the Steps if possible. Points with be awarded...
Thanks,
Prasanna.

Hi,
Add the following jar to the classpath,
<Drive>:/usr/sap/<SID>/JC00/j2ee/cluster/server0/bin/ext/com.sap.mw.jco/jrfc.jar
Hope this helps in solving the issue !
