Hi,
I'm trying to update my build script to do some conditional checking
to see if I'm deploying my code to Tomcat 5.5 or using an older version.
Is there something (like a particular file or directory) I can check
reliably that would indicate that I'm using 5.5 versus an older version?
Thanks, Jason

Thanks-- unfortunately by default (at least on Unix) that file is
not executable so it wouldn't even execute by default.

Has anyone actually created an ant task or can give me some ant
logic for doing Tomcat version detection for 5.5? Here's a snippet that
worked for Tomcat 4 and Tomcat 5.0.X that was fairly easy:

<if>
<available file="${appserver.home}/conf/Catalina" type="dir"
prope
rty="tomcat5"/>
<then>
<echo message="Detected Tomcat 5"/>
</then>
<else>
<echo message="Detected Tomcat 4"/>
</else>
</if>

Thanks, Jason

Did you bother to even LK at the script? All it does is call 'catalina.sh
version' (I'd like to think that script is executable for you). And all THAT
does is run the ServerInfo class.

Given all that, you should be able to figure something out.

Thanks Tim,

That is exactly what I was looking for, but I still can't get it to
work, and it seems that the <availabletask is somewhat broken. Instead
of just checking if the class is contained in the jar it also tries to
resolve all of its dependencies, so this is what I get when using ant -d:

Finding class
Loaded from
/

Finding class
[available] Could not load dependent class
"" for class
""
[available] Unable to load class

I can't see any flags that would tell it to not check for dependencies

Look at %CATALINA_HME%\bin\version.bat or version.sh depending on
whether you are on Windows or *nix, if you're on Windows and don't
have version.bat then you need to download the zipped distribution and
now thw windows installer.

It looks like the <availabletask tries to load the class in a new
classloader. course - doing so loads all it's super classes too - so you'd
need to also add catalina.jar to your classpath for the <availabletask.

Look at %CATALINA_HME%\bin\version.bat or version.sh depending on
whether you are on Windows or *nix, if you're on Windows and don't
have version.bat then you need to download the zipped distribution and

Yeah-- it was even lamer than that. I also had to add jmx.jar from
bin/ to classpath since that was involved in the Valve dependency from
catalina.jar
