JDK 1.4

[razmaspaz]

I'm trying to run the remote logger in a JDK 1.4 App Server (WAS 6).
I get the following error: I'm used to seeing this when a class is
compiled in a newer version of the JDK than is supported. Is the
library compatible with JDK 1.4, and if so is there something I need
to do to get it to run the:
com.allen_sauer.gwt.log.server.ServerLogImplJDK14 implementation?

gwt-log is currently compiled with Java 1.5. See http://code.google.com/p/gwt-log/downloads/list, which contains a Java version column.

You may be able to recompile it with 1.4, but I'm not sure. You can start here: http://code.google.com/p/gwt-log/wiki/UsingSourceWithEclipse

There is way more Java 5 code in there than I'm comfortable
refactoring. Is there a good place to start to figure out how to
decode the symbol maps and hydrate them before I throw them in a log
file? I've gotten to the point where I'm writing the raw request
contents to a file, but I would like to get them readable. What class
in the gwt-log library does this?

Thanks,
Michael
