Use java 1.5 apps with tomcat 6
Hi!
I'm new in this mailing list, my english is a bit poor, so I can't extend so much with my presentation, hehe :-)
I have a doubt since I'm using Tomcat 6. I think tomcat 6 need jre 1.6 for running itself, but, Can I configure it to use jre 1.5 or 1.6 for each application?
I have applications wich uses java 1.5 and other wich uses java 1.6, but I have only a tomcat 6 server installed, so I want know If I can use this tomcat for running all my apps or need another instance of tomcat 5.5 for applications wich need java 1.5.
Regards,
Spamis

Please have a look at the beginning of the catalina.sh of your
Tomcat-installation. There is a brief documentation how to set the
intended JVM. If Opensuse is using another script to start Tomcat you
will have to check if there is a setting of the environment variable
JAVA_HOME.
Basically you will have to set the variable JAVA_HOME
to "/usr/java/latest", "/usr/java/jdk1.6.0_17" or
"/usr/java/jre1.5.x_y" or where-ever the bin-directory of your JVM is.
You can have dozens of different JVM under /usr/java/ (typical place
for JDKs under Linux) installed. The selection happens through a
"JAVA_HOME=/usr/java/latest", etc..
Usually it shouldn't be necessary to export this variable as long as
catalina.sh and the environment variable setting happens in the same
process. This way the impact for the rest of the OS is kept to a
minimum.
RU,
Tobias.

Tell them that Sun no longer supports Java 1.5 and it's time to get with
the program.
How hard is it to test your app with 1.6?
$ JAVA_HOME=/opt/jdk1.6.0_14 ant test
Right?! You do have unit tests, right? ;)

Well, in that case it's up to you as to whether you risk 1.6 or not.
Members of this list usually recommend installing Tomcat from an
apache.org download because we can't keep track of where all the
different linux variants distribute parts of the server around the OS.
The Tomcat Documentation is comprehensive:
http://tomcat.apache.org/tomcat-6.0-doc/setup.html
there's also the README file in the download itself.
If you are having trouble after reading these, get back to us explaining
what the problem is and what you've already tried.

Re: Use java 1.5 apps with tomcat 6
Posted by Jimmy Spam <sp...@pobladores.com>.
I'm using opensuse official package. Maybe I should try the official
tomcat build and test it.
The programmers says that they need jre 1.5 since his apps doesn't
have tested on jre 1.6. Our programmers are dinosaurs. If they could,
they continue using cobol.

Are you using some kind of OpenSuse packaging system, or are you
installing from JREs downloaded from Sun's website & Tomcat from
tomcat.apache.org?
Why do you need jre1.5? As I said, in most cases jre1.6 is better -
faster at least.

Re: Use java 1.5 apps with tomcat 6

I understand.
I'm using OpenSuse 11.1 with Tomcat 6. I've installed on my system,
jre1.5, jre 1.6 and tomcat6.
By default, system is using jre1.6 and If I uninstall it, tomcat 6
doesn't work, so How can do for that tomcat use jre1.5 without crash?
Thank you very much.

When you start Tomcat 6, you actually start a single JVM (1.5 or 1.6)
and Tomcat runs *inside* the JVM.
Your applications run *inside* Tomcat.
You can use either 1.5 or 1.6, but the last one is usually considered to
be much better. Most 1.5 apps will run on 1.6 without modification.
Tomcat does not start JVM's for each of your applications.
