Get "connect timed out" with twitter4j api

Question

modified HelloWorldAdapter.java to call " unauthenticatedTwitter.getPublicTimeline();".
add following code before calling twitter api
System.setProperty("twitter4j.http.proxyHost", "www-proxy.us.oracle.com"); System.setProperty("twitter4j.http.proxyPort", "80");
the CEP HelloWorld CEP fails with "connect timed out"
If I use similar code (testwitter.java) outside CEP. works fine.
I am using eclipse to test the code.
--- here is part of the testtwitter.java
Twitter unauthenticatedTwitter = new TwitterFactory().getInstance();
     System.out.println("Showing public timeline.");
     System.setProperty("twitter4j.http.proxyHost", "www-proxy.us.oracle.com");
     System.setProperty("twitter4j.http.proxyPort", "80");
     try {
     List<Status> statuses = unauthenticatedTwitter.getPublicTimeline();
     for (Status status : statuses) {
     System.out.println(status.getUser().getName() + ":" +
     status.getText());
--- here is the part of the generateTwitterMessage() at HelloWorld CEP
     Twitter unauthenticatedTwitter = new TwitterFactory().getInstance();
     System.setProperty("twitter4j.http.proxyHost", "www-proxy.us.oracle.com");
     System.setProperty("twitter4j.http.proxyPort", "80");
     System.out.println("---- after seting proxyhost, call generateTwitterMessage");
     System.out.println("---Showing public timeline.");
try {
     List<Status> statuses = unauthenticatedTwitter.getPublicTimeline();
for (Status status : statuses) {
     String twitterMsg = status.getUser().getName() + ":" +status.getText();
System.out.println("msg--"+twitterMsg);
String message = this.message + dateFormat.format(new Date()) + twitterMsg ;
HelloWorldEvent event = new HelloWorldEvent();
event.setMessage(message);
eventSender.sendInsertEvent(event);
}catch ....
Please help me on proxy host/port setup inside CEP
