Hi all,
I need to know what kind of code changes are to be done while application is being migrated from WAS 4.0 to 5.1.
I appreciate Suggestions.
WAS 4.0 uses jdk 1.2 and j2ee 1.2
WAS 5.1 uses jdk 1.4 and j2ee 1.3.
We are using the Migrating tool provided by IBM. But as a developer what code changes should be done.
I know I have to take care of the assert keyword. I really appreciate of any documents or links.

Thanks

I am also working on upgrading from 4.0 to 5.1. The apps we have converted so far have converted with little problem. The new JSP compiler rejects tags that do not have proper ends. In the previous version you could leave some end tags off. I had one app in which the programer had been lazy and not done this.

We setup our http server to use the version 5 plugin so we can map apps to either the version 5.1 app server or the 4.0 app server. This allows us to migrate the apps as we have time.
