[jdom-interest] NoSuchMethodError: org.w3c.dom.DocumentType

[Tad Shimada]

Hello,

I have a very innocent looking code like this one. All I want to do is
to print out the contents of my xml file.

import java.io.* ;
import org.jdom.* ;
import org.jdom.input.DOMBuilder ;
import org.jdom.output.XMLOutputter ;

public class DOMBuilderTest
{
  public static void main( String[] args ) {
    try {
      DOMBuilder builder = new DOMBuilder() ;
      Document doc = builder.build( new File( "../linux.xml") ) ;
      XMLOutputter o = new XMLOutputter() ;
      o.output( doc, System.out ) ;
    }
    catch( IOException e ) {
      e.printStackTrace() ;
    }
    catch( JDOMException e ) {
      e.printStackTrace() ;
    }
  }
}

After compiling this code, when I tried to run it, it gave me a run-time
exception that reads as follows.

Exception in thread "main" java.lang.NoSuchMethodError:
org.w3c.dom.DocumentType: method
getPublicId()Ljava/lang/String; not found
        at org.jdom.input.DOMBuilder.buildTree(DOMBuilder.java, Compiled
Code)
        at org.jdom.input.DOMBuilder.buildTree(DOMBuilder.java, Compiled

        at org.jdom.input.DOMBuilder.build(DOMBuilder.java, Compiled

        at org.jdom.input.DOMBuilder.build(DOMBuilder.java, Compiled
Code)
        at JDOMTest.domDocument(JDOMTest.java, Compiled Code)
        at JDOMTest.main(JDOMTest.java, Compiled Code)

I have set my CLASSPATH like this.

/my_home/jdom/build/jdom.jar:/my_home/xerces/xerces.jar:\
/opt2/oraclient/sqlj/lib/translator.zip:/opt2/oraclient/jdbc/lib/classes12.zip:\

/opt2/oraclient/jdbc/charset12.zip:/opt2/j2sdkee1.2.1/lib/j2ee.jar:\
/opt2/jdk1.2.2/lib/tools.jar:/opt2/jdk1.2.2/lib/dt.jar:/home/tad:/opt2/tomcat/classes:.



As for jdom.jar, I am using beta5. Also tried beta4. As for xerces.jar,
I tried with 1.2.3, 1.2.1 and the version that came with jdom download.
They all resulted
in the same result.

Any help will be very much appreciated.

Thanks,
Tad
