It would be wonderful if we could drop that dependency. Every dependency dropped is 
a big gain, as far as I'm concerned.

Here are the uses of ORO:
./net/ontopia/Ontopia.java:    checkClass
("org.apache.oro.text.regex.MalformedPatternException", "oro.jar");
./net/ontopia/topicmaps/db2tm/Values.java:import org.apache.oro.text.regex.*;
./net/ontopia/topicmaps/utils/ltm/LTMTopicMapWriter.java:import 
org.apache.oro.text.regex.MalformedPatternException;
./net/ontopia/topicmaps/utils/ltm/LTMTopicMapWriter.java:import 
org.apache.oro.text.regex.Pattern;
./net/ontopia/topicmaps/utils/ltm/LTMTopicMapWriter.java:import 
org.apache.oro.text.regex.Perl5Compiler;
./net/ontopia/topicmaps/utils/ltm/LTMTopicMapWriter.java:import 
org.apache.oro.text.regex.Perl5Matcher;
./net/ontopia/topicmaps/webed/servlets/ProcessServlet.java:import 
org.apache.oro.text.regex.MalformedPatternException;
./net/ontopia/topicmaps/webed/servlets/ProcessServlet.java:import 
org.apache.oro.text.regex.Pattern;
./net/ontopia/topicmaps/webed/servlets/ProcessServlet.java:import 
org.apache.oro.text.regex.Perl5Compiler;
./net/ontopia/topicmaps/webed/servlets/ProcessServlet.java:import 
org.apache.oro.text.regex.Perl5Matcher;
./net/ontopia/topicmaps/webed/webapps/omnieditor/
ShowActionGroupParamRule.java:import org.apache.oro.text.perl.Perl5Util;

I agree. Feel free to replace oro.jar with java.util.regex.

r344 removes the dependency on ORO from the LTM writer.

This issue was updated by r346.

ProcessServlet never used ORO, unused import

The ShowActionGroupParamRule class is used by the webed test suite, but I'm not sure 
the test suite uses it very much. It's quite possible that one can get rid of it 
entirely. (Would be nice if we could.)

DB2TM seems to provide regexp matching to external code. Haven't fully understood 
that part of the code yet.

This issue was updated by r347.

Converted ShowActionGroupParamRule to java.util.regex

Added a separate issue #86 to decide if ShowActionGroupParamRule is needed at all

Removed label by mistake

This issue was closed by r348.
