For the Regexp demo, you need to compile the Java file.  You also need
the class files for the OROMatcher regexp library.  The .java files
tells you where to get them.  Then you need to add the class files to
classpath.
<snip>
I'm compiling the Regexp.java file using JDK1.2 and either the 
OROMatcher-1.0.7, 1.1b3, or PerlTools-1.1 distributions.  No error occur at 
compile time.  However, the following run-time error occurs:

C:\xt\demo>java com.jclark.xsl.sax.Driver Regexp.xml regexp.xsl

Is this a function of JDK1.2 or have I misunderstood something else about the 
procedure? I'm assuming that the regular expression is actually correct?

Thanks.			...edN
