Upgrade Tomcat

I have several Web apps with Forms that update, select and add to an Oracle database. I dont have JSTL or Struts and use MVC for everything I do. Everything works well and I am using Java 1.4.02 with Tomcat 4.1.27 on Windows server.

Now I will be upgrading to Java 5 and Tomcat 5.5 and would like to migrate all my Tomcat 4.1.27 Web apps to Tomcat 5.5 container. Please advise any issues I might have that will cause errors on my Web apps built and compiled under Java 1.4.02? Will they still work in Java 5 and Tomcat 5.5? Do I need to recompile under Java 5??

No you don't need to recompile.

The only issue that I ran into when migrating from 4 to 5 was with the jsp:getProperty tags.

If a String property in a bean is null, in 4x an empty String will be written to the page. In 5x, the String "null" is written.

Thanks, I assume I will have to create condition for "null" to handle that in Tomcat 5 for my getProperty tags.

Also, on another note I have learned alot from your SimpleTable MVC example that you created with a MockResultSet. It is the best MVC resultset example and helped me create a MVC working with a real Database.

Thanks.
These day's I use Bear's FrontMan front controller. It saves me a lot of time.

It is sorta covered in the JavaRanch Style Guide.
