HOW TO: Connect web service (remote application module) to existing model

Question

Hello.
I have J2EE application which displays some data in an applet, which reads them by a web service. I'd like to use persistence and connect with a web service called by applet to my current model set within a session. I tried to pass a session id to web service (to a function of an application module implementation). I wanted to create a new SessionCookie instance with such a session id and application id which are used for web application session (by ApplicationPoolImpl.createSessionCookie() or with custom session cookie factory). But I don't know how to pass a session and application ids to a sessioncookie creation process (ApplicationPool environment). I tried to use custom EnvInfoProvider, which set my properties, but it passes the params after a SessionCookie instance is created.
Samples ... AppModuleServer - file generated to provide ws functionality. I changed code to use EnvInfoProvider:
public class AppModuleServer extends Object{
  public AppModuleServer(){}
  public SomeObject[] myCustomFunction(String sessionId){
    AppModuleImpl _am = null;
    String appId="someValue";
    CustomEnvInfoProvider envProvider=new CustomEnvInfoProvider(appId, sessionId);
    try{
      _am=(AppModuleImpl)Configuration.createRootApplicationModule("data.AppModule", "AppModuleLocal", envProvider);
      return _am.myCustomFunction(sSessionId);
    finally{
      if (_am != null)Configuration.releaseRootApplicationModule(_am, false);
}CustomEnvInfoProvider:
public class CustomEnvInfoProvider implements EnvInfoProvider{
  private String applicationId;
  private String sessionId;
  public CustomEnvInfoProvider(String applicationId, String sessionId){
    this.applicationId=applicationId;
    this.sessionId=aessionId;
  public Object getInfo(String info, Object environment){
    if(info==null)return null;
    return ((Hashtable)environment).get(info);
  public void modifyInitialContext(Object environment){
    if(applicationId!=null)((Hashtable)environment).put("CookieApplicationId", applicationId);
    if(sessionId!=null)((Hashtable)environment).put("SessionId", sessionId);
  public int getNumOfRetries(){
    return 2;
}Does anybody knows how to pass information from custom EnvInfoProvider just before a SessionCookie is created (e.g. how to run modifyInitialContext() function). Or another way how to pass these information from a web service base function into ApplicationPoolImpl instance. E.g., there is parameter "properties" whithin a createSessionCookie method of ApplicationPoolImpl, which is null during calling. Is it possible to pass there some additional information?
Thanks for any suggestions.

Use the Web Service Proxy wizard in JDeveloper to create a class that calls your Web service, and then call this class from code in your AM.
