It seems no matter what I do, I get the following message when I try to do 
a substitution with the PerlUtil lib:

[Servlet Error]-[org.apache.oro.text.regex.Util: method 
substitute(Ljava/lang/StringBuffer&#59;Lorg/apache/oro/text/regex/PatternMatcher&#59;Lorg/apache/oro/text/regex/Pattern&#59;Lorg/apache/oro/text/regex/Substitution&#59;Ljava/lang/String&#59;I)I 
not found]: java.lang.NoSuchMethodError: org.apache.oro.text.regex.Util:

not found
        at org.apache.oro.text.perl.Perl5Util.substitute(Unknown Source)
        at org.apache.oro.text.perl.Perl5Util.substitute(Unknown Source)
 
Strange thing is, I know I've used this in the last year, albeit on 
Tomcat. The jakarta-oro-2.0.7.jar is in the lib directory with all the 
rest of the jars I'm using and I even rename it to jakarta-oro.jar just in 
case.

Here are the imports (took the whole kitchen sink just in case) and the 
code I'm trying to get working.

import org.apache.oro.text.regex.Pattern;
import org.apache.oro.text.regex.PatternCompiler;
import org.apache.oro.text.regex.PatternMatcher;
import org.apache.oro.text.regex.Perl5Compiler;
import org.apache.oro.text.perl.MalformedPerl5PatternException;
import org.apache.oro.text.perl.Perl5Util;

..snip

Perl5Util parseit = new Perl5Util();
String tmpAction = null;

...snip

tmpAction = eb.getActionTaken();
tmpAction = parseit.substitute("s/joe/sam/g",tmpAction);

Massive thanks in advance for any help, Joe
