Thanks Rainer.
You gave me more than hope. The tip below already does it.
You just saved my laptop, and Warszaw.

You compiled with Java 6 and try to run under Java 5. That won't work,
unless you add "-target 1.5" to your javac arguments.
I did, and it works. The servlet compiled that way on my laptop runs
fine on the server, and it even does what I wanted.
It is really a ridiculous little servlet, but considering it is going to
save installing and running Samba and winbind on 4 servers, it's worth
its weight in diamonds.
Unfortunately you didn't tell us, how you called javac on the IBM
system. I think it is recommendation number 6. ;)
I didn't because I know you guys love to guess, and I didn't want to
spoil the fun.
It's a whole process to connect to that server, and when I am connected
I lose my other connections (email e.g.). Unfortunately I didn't think
of copying the javac line before disconnecting to write the post, and I
was too lazy to reconnect. But now I did, because even if the tip above
works, I wanted to understand why the compilation didn't before.
It was of course a stupid error in the script, which I copied from my
laptop and modified for that Linux server, but not quite well enough.
This is the shell script I originally used to try to compile the servlet
on that server :
JAVA_HOME=/usr/lib/jvm/java-1.5.0-ibm/
TOMCAT_HOME=/usr/share/tomcat5
$JAVA_HOME/bin/javac -classpath
"$JAVA_HOME/lib/tools.jar;$TOMCAT_HOME/common/lib/servlet-api.jar;$TOMCAT_HOME/common/lib/commons-el.jar"
$1
And the stupid error was :
on Unix, contrary to Windows, one has to use ":" to separate classpath
components, instead of ";"
As per your recommendation # 1 I also removed the tools.jar, so the
final script which works is :
JAVA_HOME=/usr/lib/jvm/java-1.5.0-ibm/
TOMCAT_HOME=/usr/share/tomcat5
$JAVA_HOME/bin/javac -classpath
"$TOMCAT_HOME/common/lib/servlet-api.jar:$TOMCAT_HOME/common/lib/commons-el.jar
" $1
(javac is one single line)
Looks like servlet-api.jar is not on your build classpath. Look inside
the jar, you can find all the missing classes there.
That was due to the semicolons.
So, you see, if I had copied the javac line in the first post, you guys
would have spotted that error right away, and I would never have known
about the "-target 1.5" switch.
