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.

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...
But planning to migrate to 5.5 anyway.
thanks everyone

Small correction -- 5.5 needs the compat package to work on jdk l.4,
not 5.0 needs it to work on jdk 1.5. I've used TC 5.0 & jdk 1.5
together no problem.

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.
I haven't done it myself (I upgraded both at once) but
google some of these
words and you can read all about it.
PS if you do go to 5.5 and have DBCP, be sure to change your
context.xml to
the new format required by TC5.5. I spent nearly 3 days
working that out.

Hi all,
We are currently using Tomcat-5.0.28 and JDK 1.4.2_03.
We need to move onto JDK 1.5. We would build our war file using
JDK 1.5.
Can we continue to use Tomcat-5.0.28 with JDK 1.5? Do you see any
problem? Are there any known issues?
Since Tomcat 5.5 is designed to run on J2SE 5.0 [JDK 1.5] and later,
are we required to move to Tomcat 5.5 in order to move to JDK 1.5?
