Fix error "getTextContent is undefined for the type Node" for Solr project in Eclipse IDE

The error:

"The method getTextContent() is undefined for the type Node"
You get 3 of these, in the source files ReutersService.java and TestConfig.java

A Web fix that doesn't work:

You'll see suggestions that org.w3c.dom.Node.getTextContent() is only available as of Java 1.5.  But when you check you see you ARE running with Java 1.5 or later.

You can quickly check this by right clicking on the project, Properties -> Java Compiler, and confirm that 1.5 or above are in the drop down lists.

The fix, short story:

The order of the classpath needs to be tweaked in Eclipse project; shove the xml-apis-1.0.b2.jar all the way to the bottom, past the built in JVM libraries.
