Hi, everyone!
I rebuilt AV with Java 1.4, so all problems should be gone now.
Sorry for inconvenience.

Hi, Christophe!
Claude is correct, and I apologize for not testing the new build under 1.4 :-(
Unfortunately, I have no access to SNS CVS right now, so I will be able to fix it only when I am back from my vacation next Wednesday.
To all:
Btw, how many people still use Java 1.4?
Sergei

Subject: Re: archive viewer installation problem
This looks very much like the xal.jar (and hence MessageCenter.class)
was built with JDK1.5, whereas you are compiling and building with
JDK1.4. I've used classes across the transition from JDK1.3 to JDK1.4
before without a problem, but it looks like there are more
incompatibilities between 1.4 and 1.5. It's nice that the compiler flags
it, but the error message is a bit obtuse.
SNS builds XAL with JDK1.5 now, so you either have to move up to 1.5, or
request a jar file built under 1.4. I'm not sure if they have coded in
1.5 specific features, so that may or may not be possible.
