Problem while running web service client

[krsv36]

Hi,
I am using RAD7 with Websphere6.1.
When am trying to run the client main program,am getting the below exception.

Exception in thread "main" java.lang.NoClassDefFoundError: org.eclipse.core.runtime.CoreException

at test.TestClientJobDetails.main(TestClientJobDetail s.java:29)


the below is the piece of client pgm

public static void main(String[] args) {

TestClientJobDetails tst = new TestClientJobDetails();
tst.lookupByEID();
}

private void lookupByEID() {
try {

EmployeeCEDJobInformationServiceServiceLocator locator =
new EmployeeCEDJobInformationServiceServiceLocator();
System.err.println("coming inside the client..locator..."+locator);
EmployeeCEDJobInformationService service =
locator.getEmployeeCEDJobInformationService();
System.err.println("service...."+service);
long EID = 1340628;
EmployeeCEDJobResponse emp = null;

emp = service.retriveCEDJobInformation(EID);

reply as soon as possible would be appreciatable.

Thanks,
Krsv.
