It depends on what you mean by "classes". Since VisualAge for Java can't generate WAR files, you will have to use the tooling that comes with WebSphere 4.0 (the AAT -- Application Assembly Tool) to generate WAR files for your servlets and JSP's -- you simply export the Java class files into a directory structure and then use AAT to build the WAR files from there. If you mean classes that make up EJB's, then you can use the EJB 1.1 deployment tools built into VisualAge for Java 4.0 to generate EJB 1.1 compatible jar files directly. You will also want to use the AAT to assemble your WAR and EJB JAR files into Enterprise ARchive (EAR) files. This is all described in the "migration" section of WebSphere 4.0's InfoCenter and the migration documents that come with VisualAge for Java 4.0.
One more thing -- the Servlet spec and JSP spec supported by WebSphere 4.0 is the same as that supported by VisualAge 4.0 -- none of those classes will have to change. Likewise, the EJB spec supported by WebSphere 4.0 (EJB 1.1) is mostly a superset of the EJB spec supported directly by VisualAge 4.0 (EJB 1.0). Your classes will have to be repackaged as described in the previous message, but not redesigned or rewritten.
What if we spin the situation around: using VisualAge for Java 4.0 to develop for WebSphere 3.5.3. Could there be headaches when deploying the servlets and JSP's because the VisualAge for Java 4.0 WTE (WebSphere Test Environment) is no longer an accurate representation of WebSphere 3.5.3?

No, the VAJ 4.0 WTE IS the WebSphere 3.5.3 WebSphere environment. We did not update the WebSphere inside of VAJ 4.0 to WAS 4.0 because WAS 4.0 required Java 1.3... There should be no problems developing on VAJ 4.0 for deployment on WebSphere 3.5.3.
