Hello friends I try to use fop engine programatically I search for an example and I find this class
import java.io.File;
import java.io.IOException;
import java.io.OutputStream;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.Source;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.sax.SAXResult;
import org.apache.avalon.framework.ExceptionUtil;
import org.apache.avalon.framework.logger.ConsoleLogger;
import org.apache.avalon.framework.logger.Logger;
import org.apache.fop.apps.Driver;
import org.apache.fop.apps.FOPException;
import org.apache.fop.messaging.MessageHandler;
public class Invokefop
{
public void convertXML2PDF(File xml, File xslt, File pdf)
throws IOException, FOPException, TransformerException {
Driver driver = new Driver();
Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_INFO);
driver.setLogger(logger);
MessageHandler.setScreenLogger(logger);
driver.setRenderer(Driver.RENDER_PDF);
OutputStream out = new java.io.FileOutputStream(pdf);
try {
driver.setOutputStream(out);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xslt));
Source src = new StreamSource(xml);
Result res = new SAXResult(driver.getContentHandler());
transformer.transform(src, res);
} finally {
out.close();
}
}
public static void main(String[] args) {
try {
System.out.println("JAVA XML2PDF:: FOP ExampleXML2PDF\n");
System.out.println("JAVA XML2PDF:: Preparing...");
File base = new File("../");
File baseDir = new File(base, "in");
File outDir = new File(base, "out");
outDir.mkdirs();
File xmlfile = new File(baseDir, args[0]);
File xsltfile = new File(baseDir, args[1]);
File pdffile = new File(outDir, args[2]);
System.out.println("JAVA XML2PDF:: Input: XML (" + xmlfile + ")");
System.out.println("JAVA XML2PDF:: Stylesheet: " + xsltfile);
System.out.println("JAVA XML2PDF:: Output: PDF (" + pdffile + ")");
System.out.println();
System.out.println("JAVA XML2PDF:: Transforming...");
Invokefop app = new Invokefop();
app.convertXML2PDF(xmlfile, xsltfile, pdffile);
System.out.println("JAVA XML2PDF:: Success!");
} catch (Exception e) {
System.err.println(ExceptionUtil.printStackTrace(e));
System.exit(-1);
}
}
}
All the Libs from Fop are in the Classpath including the fop.jar in build directory. After
I run thejavac Invokefop.java I get this error:

6 errors
I am relatively new to Java, but with this approach I try to execute the fop engine in c++ using this java class..
Have anybody some Idea, how to solve this errors...
Thanx in advance..
