Hi
If the legacy system does not use Messaging System, and if you have a set of interfaces that,the legacy system supports you can write CORBA Object Mappers, to provide an interface to the Legacy system and then use either EJB or Java Client to acess the CORBA object using RMI-IIOP to access the Legacy System.
You can probally get more information about Object Mappers to know the exact details.
If you do not have access the interface provided by the Legacy System you can use Java Based Screen Scrapers. Screen Scrapers read data of the 'Green Screen' and provide you with probally a Web based interface. The problems with this method is that you will have to use a thrid party Screen Scrapper Software, and any change in the 'Green Screen' will require change in the Configuration of the Screen Scrapper.
