Which Browser for Java 1.2?

We have an ancient application (an old service processor for proprietary
hardware) that is manageable only by a browser running Java 1.2. Does
anyone know of a browser that will work with JVM 1.2 that can be installed
on Windows 2003? MSIE 7 just dies when run with JVM 1.2. Firefox 1.5
won't work with it either. MSIE 6 works fine, but I cannot find a way to
install MSIE 6 on Windows 2003 without completing messing with the MSIE 7
installation.

Can't you just decompile the application and recompile for use with a
newer JVM?

Fearsome grindings.

Not possible for reasonable cost. The java is embedded into proprietary
hardware.

Can you not use appletviewer from the JDK?

Why do you say that? What Java 1.2 bug* does it rely on?

* That is the only thing I can think of, that would lock
a Java application or applet to a specific version of
the JRE.

..also as used by Java web start (for launching
applets*). JWS is also good for JRE versioning**.

They wrote the application with hard-wired logic to stop working on any JVM
that is not 1.2.

I'm not defending it. I'm trying to work around it.

I'll try it.

I assume that the hard-wired logic is equivalent to System.getProperty
("java.version").equals("1.2"); if so, then maybe running with -
Djava.version=1.2 might fix it.

Install some virtualization software and run
Windows 2000 + MSIE old + Java old on that.
