Tomcat 3.2 versus 4.1
Hi,
I'm considering upgrading from Tomcat 3.2 to Tomcat 4.1.
I wonder if the performance and other improvements between the two releases
are major and if the upgrade itself is painful.
Is there a document instructing how to do such an upgrade?
Thanks, ronen

Ok I got it working.. my mistake .. for some reason never had a lib
directory inside java1.4 directory . It had the tools.jar file in it. Now it
works just fine.

Hi ,
I have been fighting with this problem for quite sometime now. Can
anyone tell me what the problem could be.
I have jdk1.4 installed with tomcat 3.3.1 on a Unix box.
I have set the JAVA_HOME directory set to point to java1.4 .
And when I do java -fullversion I do get java full version "1.4.0-b92"
Now I get this error when I try to run a jsp
org.apache.jasper.JasperException: Unable to compile error: Invalid class
file format in /usr/java1.4/jre/lib/rt.jar(java/lang/Object.class). The
major.minor version '48.0' is too recent for this tool to understand.

I made a few searched on the web and everyone say that its because of
version mismatch . I am not able to figure out where exactly I need to
change what.
One suggestion was to replace tools.jar but I don't see that jar file being
used by jdk1.4 at all. Any suggestions will be most welcome.
Thanks
Shankar

Re: Tomcat 3.2 versus 4.1

Hi Ronen,
We just completed the upgrade ourselves. For our applications, we are getting
MUCH better performance with Tomcat 4.1. We had an issue with CPU usage
constantly increasing over time with 3.2.4, which seemed to go away with 4.1.
The upgrade wasn't too bad, we just installed 4.1, copied over all our webapps,
wrote a script to change server.xml, and made some custom configurations to
web.xml, changed workers.properties and httpd.conf for the apache connection.
Everything went well for the most part. We are actually using the same JK
connector that we used with tomcat 3.2.4.
We did run into several bugs, but everything we need seems to be ironed out
with the 4.1.17 version.
