I think these are both in the release/changes notes that I posted a link to earlier in this thread - so yes these are real issues. -Original Message- From: Mark Leone [mailto:[EMAIL PROTECTED] Sent: Friday 27 May 2005 02:14 To: Tomcat Users List Subject: Re: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5 Sounds like the consensus is that Tomcat 5.0.x will work with jdk 1.5. FWIW I found the following two problems trying to run code built for jre 1.4 in a 1.5 jvm. 1. A couple DOM classes (don't remember which ones, but you'll know it if you run in to them) had some methods added in jdk 1.5. If you try to load an implementation class for one of these that was developed in jdk 1.4, you'll get missing method implementation errors. To resolve, you can add empty method specifications for the classes that require them, or upgrade to an XML parser that was written for jdk 1.5. 2. JDK 1.5 uses the symbol enum as a reserved keyword. You'll have to change any and all occurrences of this symbol in your code (where it is used as a variable name) to something else, e.g. enumer. There may be other backward compatibility issues, but these are the two that I've run into. -Mark Tim Diggins wrote: And, oops, I'm sorry for spreading the original FUD - Following this thread, I've just tried again to get everything working on tc5.0/jdk1.5 and hey-presto, everything ok - guess I must've had TC running on jdk1.4 after all...

Re: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5
I'm not an expert, but I believe (from experience previous googling) that tomcat 5.0.x will respond with an exception (IncorrectClassFileFormat or something) when it encounters class files compiled with jdk1.5, and that thus yes you need 5.5. There are some recent threads about migrating from 5.0 to 5.5, in particular I recall discussion of change of default logging library. -- Tim Raverkar, Sachin (Sachin) wrote: Hi all, We are currently using Tomcat-5.0.28 and JDK 1.4.2_03.

Re: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5
Exception about class file format would be encountered only if tomcat would be run on a jvm 1.4 and you deploy a war containing 1.5 compiled classes. If you run tomcat with jvm 1.5 it should be able to load classes from a war containing 1.5 compiled classes. The main problem which could arise is if tomcat 5.0.x uses a java class or method which disappeared on jvm1.5. Just give it a try :) Le Jeudi 26 Mai 2005 11:28, Tim Diggins a écrit : I'm not an expert, but I believe (from experience previous googling) that tomcat 5.0.x will respond with an exception (IncorrectClassFileFormat or something) when it encounters class files compiled with jdk1.5, and that thus yes you need 5.5.

The main problem which could arise is if tomcat 5.0.x uses a java class or method which disappeared on jvm1.5 This would be doc'd in 1.5 release notes, didn't notice anything relevant when I upgraded: http://java.sun.com/j2se/1.5.0/compatibility.html Also, why would the TC team release a compatibility package for 5.5 on 1.4 if they thought it wouldn't run anyway?

You can run 5.0.28 on jdk1.5 but you need to add a compatibility package which is available from the tc downloads page. Basically it adds 3 jars to fix issues with xml compatibility with the 1.4 vm.

RE: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5
I was not looking forward to reconfiguring logging, as it'd always been an area that generated some confusion, but if anything logging is easier on 5.5 than 5.0 IMHO. I had Loggers configured in 5.0, but these are redundant in 5.5, so I have no logging config at all now - I just use the java.util.logging classes in my servlet code (no changes at all since it ran on 5.0), and it works perfectly for my needs without any config file at all. -Original Message- From: Tim Diggins [mailto:[EMAIL PROTECTED] Sent: Thursday 26 May 2005 10:28 To: Tomcat Users List Subject: Re: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5 I'm not an expert, but I believe (from experience previous googling) that tomcat 5.0.x will respond with an exception (IncorrectClassFileFormat or something) when it encounters class files compiled with jdk1.5, and that thus yes you need 5.5.
