QUESTION POSED ON: 24 January 2002
I am currently at V4R5. I have OS/400's HTTP default server running. Soon I will be moving to V5R1. I am planning on implementing the Apache server.

My question is: Does IBM's WebFacing tool require WebSphere, or can it be used with Tomcat?

The issue here is that I understand that WebSphere soon won't be free, right?

The WebFacing Tool creates standard JavaServer Pages, Java beans and servlets that will run in any application server that supports the standards for these Java components. We have sanity tested WebFaced applications on Tomcat and we found no problems, but we have not completed exhaustive testing. There are a few Tomcat limitations that I'm aware of:

It can't debug JSPs and servlets because there is no kicker class in Tomcat. The iSeries AD team created the kicker class for WebSphere Application Server. Non-Latin National Language support is problematic. The WebFacing team suspects that the Tomcat NL support will not handle WebFaced applications.

When you start to have substantial e-business traffic on your application server, you will want to upgrade from Tomcat to WAS.

Reasons:

reliability
scalability
security
throughput / performance tuning
