[jdom-interest] jdom2 migration issue

[Craig Christophersen]

In the open type window it does show another project in eclipse with "org.jdom.Document".  But it is another project that I will migrate also once I get it working in this project.  The other project is not referenced by the current project.

There are 8 classes in the project that use jdom.  Below is a typical import:

import java.io.*;
import java.util.*;
import java.util.regex.Pattern;

import org.jdom2.*;
import org.jdom2.filter.ElementFilter;
import org.jdom2.input.SAXBuilder;

And another class imports:

import java.io.*;
import java.util.*;
import java.io.File.*;
import java.io.IOException;
import java.util.concurrent.ConcurrentLinkedQueue;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.jaxen.JaxenException;

import org.jdom2.output.*;
import org.jdom2.*;
import org.jdom2.filter.ElementFilter;
import org.jdom2.filter.ContentFilter;
import org.jdom2.input.*;
import org.jdom2.xpath.*;

In eclipse, edit your file, then type shift-ctrl-T
Then type org.jdom.Document

In the box below, you have all the locations of jdom 1.x Documents.

As a double-check, can you copy/paste the entire import section in your
class.... I am convinced there must be an import from org.jdom.* or
something.

P.S. when you reply, do a reply-all, and I will get your answer
faster.....
