Debian 4.0. and java 6

[Toni Tortosa <tt...@obertic.com>]

Hello,

I have compiled openbravo software in my local laptop with tomcat 5.5. 
and java 6 with no problems, but when I copy some new classes to my 
server it shows an error message (Bad version in class that I have just 
modified). My server is debian and it runs tomcat 5.5. and java 5.

Well, I tried to install java6 in my debian by means of backports 
unstable and I restarted tomcat after modify my environment java 
variable. Then tomcat doesn't show its main page and neither shows 
openbravo pages. Tomcat status returns that the service is not error, 
but yes existing an active pid file.

Must I have modify something else to do run tomcat 5.5 with java 6 in my 
Debian 4 server? Somebody have tried this? Thanks

There's your problem: you are trying to run classes compiled using a
newer compiler (Java 6) with an older JVM (Java 5).

As Chuck suggests, download Sun's JVM and install it yourself, rather
than using Debian's package-managed versions. It doesn't look like Sun's
JDK or JRE 1.6.x are available through apt-get. If you want to know more
about running Debian's package on Debian, you should ask someone at Debian.

Why don't you install a real JVM download from the Sun web site?  You
should remove the existing one first to avoid confusion.

Alternatively, when you build on your JDK 6 platform, set the target for
1.5 to allow such classes to be used on your existing server JVM.

(This is all basic Java, nothing to do with Tomcat.)
