Subject RE: Problem with Tomcat 4.0.1 installer: Cannot find JDK!
Date Sat, 29 Dec 2001 14:37:35 GMT

I too have experienced the same problem trying to get
Tomcat 4.0.1 to install on Windows when i *do* have a
valid Sun SDK (d:\jdk1.3.1_02). I have already checked
the registry as I suspected that this is where the
Tomcat installer is looking and the relevant entries
are there - yet i am still getting the same error
message from the tomcat installer as per the orginal
poster of this thread. The difference is that I am
using NT4SP6a so are there any other registry entries
i should be looking for?

for reference here are my registry entries:-

HKLM/SOFTWARE/JavaSoft/Java Development Kit
CurrentVersion = "1.3"
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.3
JavaHome = "D:\jdk1.3.1_02"
MicroVersion = "1"
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.3.1
JavaHome = "D:\jdk1.3.1_02"
MicroVersion = "1"
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.3.1_02
[no entries - aside from default]

I have tried entering the JavaHome and Microversion
keys to:-
HKLM/SOFTWARE/JavaSoft/Java Development Kit/1.3.1_02
with no effect, and also amended the CurrentVersion
key to "1.3.1_02" again with no luck.

Any other suggestions?

The Tomcat 4.0.1 installer for Windows uses register
entries to detect the
JDK installation directory. Check the value of
CurrentVersion under
Kit. For instance, in
my computer I have 1.4. Then, check JavaHome under
Kit/1.4 (in my case),
which must point to the java directory. The error you
report seems to happen
when the installer is unable to find the current
version value.

Hope it helps
