Dear Aushutosh
It's right that WebSphere need to run as a service on your machine hence there is no separate version for 98. The other question about VAJ is true that VAJ & WAS goes hand in hand as you can deploy
EJB's right from VAJ..and it also a very good debuger tool for your code..
Last but not least you can upgrade your m/c to Win'2000 any version ..WAS is available for all..
All the best..
Cheers..Johnson
