#5 Crimson and JDK 1.4 dependencies

[Scott Stirling]

Hi,

This plugin has a dependency on crimson parser, but
crimson.jar is not supplied, and it's not indicated in the
plugin.xml or anything.

See net.sourceforge.easysql.wizards.ConnectionWizard:

import org.apache.crimson.util.XmlNames;

and see:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

It would be nice to advertise the dependencies on the
plugins page for those of us still using JDK 1.3.x!

Another problem is that even if I do add crimson.jar to
the classpath for the plugin, then I get LinkageErrors
because, presumably, the XML API interfaces have
already been loaded by another plugin. This seems like
it may be a bug in IBM's code:

java.version=1.3.1_05
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86,
WS=win32, NL=en_US
Command-line arguments: -os win32 -ws win32 -arch
