Because I need JDK 1.3... Version 4 of VAJ came with a copy of the WebSphere Studio Application Developer product, but I don't know how different this is to Visual Age. If developers are going to have to use a new product to replace their use of Visual Age and they are already using WebGain Visual Cafe (the company choice because it integrates with WLS), there seems no point in going to WebSphere Studio Application. Can anyone who has used both VAJ and the WebSphere App Developer environment tell me how they are similar / differ ? I like VAJ and would like to continue using it but don't fancy another different IDE.
