Weblogic does not call the ProxySelector class for http url

Question

We are using weblogic server for our project. I have created a ProxySelector class and made it the default in my code. When my code tried to access the external url, the ProxySelector is called for socket url but not http url. Because of this, I am not able to return any HTTP proxy object from the ProxySelector and it fails.
Note: The code works fine if I execute it from tomcat.

Hi This is the method that I have for invoking webservices. It uses a Dispatch API. The myProxySelector is an instance of MyProxySelector which is already made defult in the appication startup.
This MyProxySelector has a threadlocal variable useProxy to indicate whether the proxy should be used or not. so I am setting the variable just before reply = dispatch.invoke(sm);
public class WebServiceDispatch {
public Object invoke() throws GLException {
Object result = null;
try {
Service service = Service.create(getOperation().getServiceName());
service.addPort(getOperation().getOperationName(), SOAPBinding.SOAP11HTTP_BINDING, call.getServiceEndpoint());
Dispatch<SOAPMessage> dispatch = service.createDispatch(getOperation().getOperationName(), SOAPMessage.class, Service.Mode.MESSAGE);
initHandlers(dispatch);
Map<String, Object> ctx = dispatch.getRequestContext();
if (call.useWSS()) {
ctx.put(SOAPConstants.WSSE_SECURITY, new WSSHeader(getCredentials().getUsername(), getCredentials().getPassword(), call.sendEncryptedPassword()));
} else if (call.getCredentials() != null ) {
String user = getCredentials().getUsername();
if ( user != null ) {
ctx.put(Dispatch.USERNAME_PROPERTY, user);
if (getCredentials().getPassword() != null ) {
if (call.sendEncryptedPassword()) {
ctx.put(Dispatch.PASSWORD_PROPERTY, getCredentials().getPassword().getEncryption());
} else {
ctx.put(Dispatch.PASSWORD_PROPERTY, getCredentials().getPassword().getText());
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage sm = mf.createMessage();
SOAPHeader sh = sm.getSOAPHeader();
SOAPBody sb = sm.getSOAPBody();
for ( Iterator<?> it = call.getOperation().getOrderedParameters().iterator(); it.hasNext(); ) {
WebServiceParameter parameter = (WebServiceParameter) it.next();
if (parameter.isBodyParam()) {
sb.addChildElement((SOAPElement)call.getParameterValue(parameter));
} else {
sh.addChildElement((SOAPElement)call.getParameterValue(parameter));
String endPoint = call.getServiceEndpoint();
myProxySelector.setUseProxy(useProxyServer);
if (getOperation().getReturn() != null) {
reply = dispatch.invoke(sm);
result = getReplyElement(reply);
call.setParameterValue(getOperation().getReturn(), result);
} else {
dispatch.invokeOneWay(sm);
} catch (Throwable t) {
throw GLException.factory(new CausedBy("Error Invoking Web Service Dispatch"),t);
return result;
