Fop Factory Run time exception - apache-fop

Question

i am trying to execute the following code
import java.io.File;
import java.io.OutputStream;
//JAXP
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Source;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.sax.SAXResult;
//FOP
import org.apache.fop.apps.FOUserAgent;
import org.apache.fop.apps.Fop;
import org.apache.fop.apps.FopFactory;
import org.apache.fop.apps.MimeConstants;
/**
* This class demonstrates the conversion of an XML file to PDF using * JAXP (XSLT) and FOP (XSL-FO).
*/
public class xml2pd {
/**
* Main method.
* #param args command-line arguments
*/
public static void main(String[] args) {
try {
System.out.println("FOP ExampleXML2PDF\n");
System.out.println("Preparing...");
// Setup directories
File baseDir = new File("e:");
File outDir = new File(baseDir, "out");
outDir.mkdirs();
// Setup input and output files
File xmlfile = new File(baseDir, "ajay.xml");
File xsltfile = new File(baseDir, "test.xsl");
File pdffile = new File(outDir, "ResultXML2PDF.pdf");
System.out.println("Input: XML (" + xmlfile + ")");
System.out.println("Stylesheet: " + xsltfile);
System.out.println("Output: PDF (" + pdffile + ")");
System.out.println();
System.out.println("Transforming...");
// configure fopFactory as desired
**strong text**FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
// configure foUserAgent as desired
// Setup output
OutputStream out = new java.io.FileOutputStream(pdffile);
out = new java.io.BufferedOutputStream(out);
try {
// Construct fop with desired output format
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
System.out.println("After MIME_PDF");
// Setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));
// Set the value of a <param> in the stylesheet
transformer.setParameter("versionParam", "2.0");
// Setup input for XSLT transformation
Source src = new StreamSource(xmlfile);
// Resulting SAX events (the generated FO) must be piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
} finally {
out.close();
}
System.out.println("Success!");
} catch (Exception e) {
e.printStackTrace(System.err);
System.exit(-1);
}
}
}
(this is an example copied from http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/examples/embedding/java/embedding/ExampleXML2PDF.java?view=markup) but i am getting the following runtime error...
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

can anybody help me to resolve this...?
thanks in advance.

You need commons-logging package (e.g. commons-logging-1.0.4.jar). To do this, just download and put it in your classpath.
