Java Forum / General / May 2007Updating to Java 5
Please forgive my terminology... My new job means that I'll be supporting & enhancing a 4 year old struts application. It uses the JDK 1.3 It runs on jakarta-tomcat-4.1.24 It is deployed to remote laptops via Java Web Start (1.0.1 I think) It connects to an Oracle 9i database. Before I get too busy making the application better, I want to upgrade the various versions Does anyone know of any issues that I might face when I upgrade to Java 5, Tomcat 5 and the latest Java Web Start?

Upgrade to Java 5 should be relatively painless, unless the 1.3-based code uses "enum" or "assert" as identifiers. Even then you can compile code "-target 1.3". Java 1.4 came out five years ago. Java 5 came out two-and-a-half years ago. Java 6 is already out, and has been for months. Why did you settle on a version that is not the latest? Tomcat should give no upgrade issues. Web Start isn't dependent on the Java version. Au contraire you can set it up to ensure the client has any particular version the program needs.

I use IntelliJ Idea. It will convert all my loops to the new for:each form with a single click. IntelliJ flushes out all sorts of bugs and questionable code, e.g. code that does not do anything.
