开发时的环境配置如下：
写一个启动类加载和绑定hibernate的sessionfactory到weblogic下
代码如下：
public class hibernatestartup implements t3startupdef {

  public static string config_file_path = "/hibernate.cfg.xml";

 public void setservices(t3servicesdef services) {}
 public static final string session_factory_jndi = "hibernate";
    public static final string url = "t3://localhost:7001";
  public string startup(string name, hashtable args) throws exception {
    try {

           dobind();
           return "hibernate startup completed successfully";
        } catch (exception e) {
         
       }
       return "hibernate startup completed successfully";
  }
  private static void dobind( ) throws exception
   {
       properties  environment  = null;
       initialcontext  context  = null;

       try
       {
         environment = new properties( );
         environment.put( context.initial_context_factory,"weblogic.jndi.wlinitialcontextfactory");
         environment.put( context.provider_url, url );
         context = new initialcontext( environment );

         configuration configuration = (new configuration()).configure(config_file_path);
         sessionfactory factory = configuration.buildsessionfactory();
           if (factory == null)
               throw new exception("sessionfactory cannot be built?!");

           try
           {
               if( context.lookup("hibernate")!= null )
               {
                 context.rebind("hibernate", factory);
               }
               else
               {
                 context.bind("hibernate", factory);
               }
           }
           catch ( namingexception nameex )
           {
             nameex.printstacktrace();
               context.bind("hibernate", factory );
           }
       }
       catch ( namingexception nameexp )
       {
           throw new exception( "namingexception: " + nameexp.getmessage( ));
       }
       catch( exception excp )
       {
           throw excp;
       }

   }

  static private initialcontext getinitialcontext() throws exception {
   string url = "t3://localhost:7001";

   properties properties = null;
   try {
     properties = new properties();
     properties.put(context.initial_context_factory, "weblogic.jndi.wlinitialcontextfactory");
     properties.put(context.provider_url, url);
     return new initialcontext(properties);
   }
   catch(exception e) {
     logger.fatal("unable to connect to weblogic server at " + url);
     logger.fatal("please make sure that the server is running.");
     throw e;
   }
 }
}
然后编译
在jbuilder2005的configserver下的calsspath下面加入这个类的所在路径，我的是c:/work/overstock/classes
然后把hibernate用到的jar文件也加入，就可以开发了。

部署的时候只要把这些路径加入到domain的startweblogic.cmd中就可以，不过要把c:/work/overstock/classes中的类打成jar包再加，要不weblogic会找不到的。
