class not found FOP

Question

Hi so i am trying to use FOP to turn an xml file into pdf and i keep on running into errors, right now i have the error

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xmlgraphics/io/ResourceResolver
at org.apache.fop.apps.FopConfParser.<init>(FopConfParser.java:122)
at org.apache.fop.apps.FopFactory.newInstance(FopFactory.java:132)
at run.ExampleFO2PDF.main(ExampleFO2PDF.java:62)

i have the FOP library in the build path as well as xmlgraphics and commons logging and Avalon framework

This is the code i am trying to run

        import java.io.BufferedOutputStream;
        import java.io.File;
        import java.io.FileNotFoundException;
        import java.io.FileOutputStream;
        import java.io.IOException;
        import java.io.OutputStream;

        import javax.xml.transform.Result;
        import javax.xml.transform.Source;
        import javax.xml.transform.Transformer;
        import javax.xml.transform.TransformerConfigurationException;
        import javax.xml.transform.TransformerException;
        import javax.xml.transform.TransformerFactory;
        import javax.xml.transform.sax.SAXResult;
        import javax.xml.transform.stream.StreamSource;

        import org.apache.fop.apps.*;
        import org.xml.sax.SAXException;

       public class pdf{
        public static void main(String[] args) throws SAXException, IOException, TransformerException
  {
        FopFactory fopFactory = FopFactory.newInstance(new File("."));
                OutputStream out = new BufferedOutputStream(new FileOutputStream(new File("D:/temp/myfile.pdf")));
                try {
                  Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out);
                  TransformerFactory factory = TransformerFactory.newInstance();
                  Transformer transformer = factory.newTransformer(); // identity transformer
                  Source src = new StreamSource(new File("D:/temp/test.xml"));
                  Result res = new SAXResult(fop.getDefaultHandler());
                  transformer.transform(src, res);
                } finally {
                  //Clean-up
                  out.close();
                }
           }

    }

Answer 1

abstract interface org.apache.fop.apps.MimeConstants implements org.apache.xmlgraphics.util.MimeConstants

org.apache.xmlgraphics.util.MimeConstants belong to xmlgraphics-commons-1.5.jar. Just include xmlgraphics-commons-1.5.jar in your classpath, it will resolve the issue.

Answer 2

I guess you've figured out this one - but anyway for those that haven't: The trunk of FOP 1.1 does have the FopConfParser which references the xmlgraphics.io.ResourceResolver

http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/src/java/org/apache/fop/apps/FopConfParser.java?view=markup

and the trunk of xmlgraphics commons does have the ResourceResolver:

http://svn.apache.org/viewvc/xmlgraphics/commons/trunk/src/java/org/apache/xmlgraphics/io/ResourceResolver.java?view=log

So as a solution, update to trunk! Happy coding :)
