I can't get the XML parser to work with jEdit 4.2 final on a new Windows installation. Otherwise, jEdit runs fine.

When I try to use the plugin with an HTML file, I'm told that xml.parser.HTMLParserImpl didn't load because the class xml/parser/XmlParser wasn't found. Seems like those slashes should've been dots. The stack trace is at the end of the message.

I also get an error message, at the same time, that org.apache.xerces.jaxp.SAXParserFactoryImpl wasn't found.

After this, I have to use the Plugin manager to unload the XML plugin before I can type greater-than characters into any buffer that the XML plugin normally works with. Also, none of the functionality of the plugin is available.

Any ideas on how to fix it?


The stack:

java.lang.NoClassDefFoundError: A class required by class: xml.parser.HTMLParserImpl could not be loaded:
