VisualAge Generator to Enterprise Generation Language Migration Guide
EGL is the strategic component in WebSphere Studio to which VisualAge
Generator customers should migrate. EGL support is not meant to be a
complete replacement for ALL functions and platforms supported by
VisualAge Generator Developer 4.5 (VAGen). Depending on your
target environment and the types of programs you have developed with VisualAge
Generator, you might need to wait for a future release of EGL.
The following list shows VisualAge Generator target environments supported
in the current release of EGL.
-
MVS CICS
- MVS Batch
- Unix System Services
- Windows Native
- AIX Native
- Linux on Intel platforms
- iSeries
- Note:
- While VisualAge Generator generates Java and C++ for certain platforms, EGL
only generates Java.
For additional considerations in these supported environments, see the
following:
The following tables list special considerations for supported
environments.

JSP and Java servlets which use VAGen Java wrappers
|
- You can migrate your JSP and Java servlets to WebSphere Studio using the
information provided by WebSphere Studio.
- You can migrate your VAGen server programs to EGL using this VAGen
migration guide. You can generate the Java wrappers using EGL.
|
Java GUI applications or applets that do not use VAGen parts
on the free form surface, but which use VAGen Java wrappers.
|
- You can migrate your Java applications or applets to WebSphere Studio
using the information provided by WebSphere Studio for migrating Java code
from VisualAge for Java.
- You can migrate your VAGen server programs to EGL using this VAGen
migration guide. You can generate the Java wrappers using EGL.
|
Java GUI applications or applets that use VAGen parts on the free form
surface.
| Not supported in the current release.
|
