Webservice in NWDS having JCO code

Question

Hi All,
I have a requirement which is to create a JAVA web service in NWDS which can service a .NET internet Application take some data from .NET and
put it into the SAP by calling a RFC Module...
I have written a class which has two methods
it simply connects to SAP & processes the RFC Module...
This class works fine if i run it as a
standalone java application with a main
method.. <b>but it fails</b> when i deploy it as a web service and try to run it through a Standalone
Client ... it is able to create the
WSDL and the methods are also visible but it
fails from the code where JCO logic starts...
I am getting the error message as
<b>Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.
wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory

I am using sapjco.jar in the project properties dialog box but it is not there when the EAR is generated & deployed..
Can this be a problem ??? If yes where should i put
this sapjco.jar
Please help me out as i am really facing a hard time finding out the reason for this

Hi Maksim,
Thankyou so much maksim for the jar file path
you had given , the first error is gone
when i put the jar file in project
properties.
But i am still getting some errors
because of the JCO library methods that
i am using ... all other simple web services
work fine in my system but i am getting
following errors
<b>javax.xml.rpc.soap.SOAPFaultException: com/sap/mw/jco/JCO
     at com.sap.engine.services.webservices.jaxrpc.
wsdl2java.soapbinding.MimeHttpBinding.
buildFaultException(MimeHttpBinding.java:651)

     at proxy.ConfigBindingStub.setEclipseData(ConfigBindingStub.java:96)
     at com.carrier.isa.Client.main(Client.java:29)</b>
when i put a simple code like
                <b>JCO.Client aConnection=null;
          IRepository aRepository=null;
          try {
               System.out.println("Creating a client");
               aConnection=JCO.createClient(
                                             SAP_CLIENT,
                                             USER_ID,
                                             PASSWORD,
                                             LANGUAGE,
                                             HOST_NAME,
                                             SYSTEM_NUMBER);</b>                                             System.out.println(aConnection.toString());
          ArrayList array=new ArrayList();
          array.add("Tarun");
          array.add("Abhay");
          array.add("Sujit");
          array.add("Sandy");
          array.add("Sachin");
          returnStr=array.get(2).toString()"--"test;
          catch(Exception e)
               e.printStackTrace();
          return returnStr;
the code above is just a snippet of the whole .
I have sapjco.jar in project properties in NWDS or eclipse but this jar is missing when
i build an EAR in the Web services perspective..
Can the missing of this jar in the
project EAR be the cause of problem ...
if yes let me know where should i add it ...
Also, I created a simple java project so i
am not having any WEB-INF folder ...
do i need to create a web project instead ..
Please help me as you did earlier ..
I would be highly obliged ....
