[opencms-dev] Problems with Tomcat

[Jonathan Woods]

Vitor -

I guess all the things I suggested are possible only if you manipulate the
batch files which run Tomcat, and that takes a bit of work, so sorry if
they're not useful.

1.  JAVA_HOME pointing to the location you gave is fine - don't bother
changing it to the JRE root.  I'm not sure what you mean by 'the JVM on
Tomcat' - as far as I remember, Tomcat batch files only take notice of
JAVA_HOME, CATALINA_HOME and CATALINA_BASE, and I don't think the last two
would be the cause of your problem.

2.  By 'validity' of the Tomcat binary, I meant verifying that the checksum
or signature of the downloaded binary is what the nice people at Apache say
it should be; helps to confirm that you haven't downloaded a
hacked/compromised version.  Maybe I'm too paranoid, but one of these days
someone is going to hack a major open source project again.  At e.g.
http://tomcat.apache.org/download-55.cgi you will see pgp and md5 links; you
can get a Windows version of the md5 checksum utility at
http://downloads.activestate.com/contrib/md5sum/Windows/.  (I'm not sure of
the official location, but this looks safe - your risk, though.)

3.  I was wrong about Java class file versions.  Since you're running Java
1.5, it ought to be able to read class files produced using earlier versions
[of javac] - but clearly there's something wrong with the class files you're
trying to load.  I'm only sorry I can't hazard a quick guess as to what it
is!

How can I check the Java version that Tomcat is running?
As I mentioned before, JAVA_HOME environment variable is set to:

C:\Program Files\Java\jdk1.5.0_06

and the JVM on Tomcats points to:

C:\Program Files\Java\jre1.5.0_06\bin\client\jvm.dll

(BTW I already tried to point the JVM to one of the other jvm.dll files
available under the jdk1.5.0_06 folder, but the errors still persisted).
Is anything wrong with any of these? should the JAVA_HOME point to another
location (like JRE)? What about the JVM?

I tried to redownload and reinstall Tomcat but the errors persist.
(what do you mean by checking the validity of the binary?)

Could you be more specific, pleas?

Thanks for the info.
