My classpath has: d:xml-xercesjava oolsxerces.jar; d:jaxpjaxp.jar; d:jaxpxalan.jar; d:jaxpcrimson.jar; If I am in my *.java source file and run the following: import org.w3c.dom.*; import org.xml.sax.*; import javax.xml.parsers.*; Everything is fine, but when I try and use: import com.sun.xml.tree.XmlDocument; Everything is wrong. I looked up com.sun.xml.tree.XmlDocument, supposedly it is a part of JAXP but I have already installed and updated my classpath with this library. Moreover, I can already reference a class in the JAXP More>>

com.sun.xml.tree.* is contained in a jar called "parser.jar" that is not in your classpath.

I suggest you to not import com.sun.xml.* (it's wrong...) and to read more about jaxp to keep xml "implementation independency".

Is a good practice to import only org.w2c.dom.*, org.xml.sax.* and javax.xml.parsers.*, and no more third part xml packages.

xerces.jar is a parser (from Apache group),

crimson.jar is another parser (from Apache group, involved from Project X),

parser.jar is another one (Project X from Sun)...

May be wrong to keep different implementation of the same thing in the classpath...
