java.lang.ClassNotFoundException: com.ibm.ejs.ras.hpel.HpelHelper

Question

Good day,

I have a simple http post java main function as follow:

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.conn.HttpHostConnectException;
import org.apache.http.impl.client.DefaultHttpClient;


public class Test {

    public static void main(String[] args) {
        try {
            System.out.println("java version: " + System.getProperty("java.version"));
            HttpClient httpclient = new DefaultHttpClient( );
            HttpPost post = new HttpPost("http://www.google.com");
            HttpResponse response = httpclient.execute( post );
            System.out.println("response is " + response);
            } 
        catch ( HttpHostConnectException ce ) {
                System.out.println("Service is not available. Please try again later." );
            } 
        catch ( Exception e ) {
                System.out.println("e is " + e);
            }
    }
}

I have some java project in IBM RAD, when I run this code in 1 of the project, I will get http 200 response. However, in another project, I run the same code, I will get error as follow: Failed to instantiate [ch.qos.logback.classic.LoggerContext] Reported exception:

Both of the project include the same com.ibm.ws.runtime.jar.

Both project is java 1.6.

Please advise. Appreciate your help.
