connecting to other Apps
I am trying to connect to an application called Attachmate Extra!.
I have created this connection using VBA, but i would start using Jave instead.
here is the block of code in VBA
Private Sub objGetExtra()
Set System = CreateObject("EXTRA.System")
Set Sessions = System.Sessions
Set Sess0 = System.ActiveSession
End Sub 'end of objGetExtra sub function
then to send instruction to the application using this connection, i use this
Sess0.Screen.SendKeys ("<Tab>")
I have created a connection to an access database using java. Would the connection to another application be similar?
Thanks in advance

The code you show uses the ability of Extra! to expose its functionality
as an ActiveX server (or OLE automation server), just like Word or Excel
do. VB, C++, C# (Microsoft stuff) can quite easily access ActiveX
objects. Java can also do it, but it's not that easy. In your place, I would
investigate:
1. Does Extra! offer a Java interface?
2. Maybe another terminal emulation does.
3. Various ways to connect from Java to ActiveX. Check the Sun ActiveX bridge. I know it exists, but not more than that. Google for other solutions.
4. If none does the trick, study JNI, which allows Java programs to call native stuff (like a DLL). JNI has nothing specific for ActiveX, but It can be used to call Windows and Attachmate native API's.
I tried to find out if Extra! has Java support - but no luck there
however there is another terminal emulation i can use. (please bear with my terminology if it not 100% accurate) Its called the IBM WebSphere Host On Demand. This opens in a browser and then it opens up another window that has the session. As its trying to open up the session, the Java sunburst loading come up. So i believe it is using Java.
Would it be easier to use this rather that Extra! if i stay with Java? Or should I use VB and go with Extra!
I am sorry if i dont make sense, but i am fairly new to developing and would appreciate any help
