close the Stream in the CommandLineStarter

[Juergen Lippold]

Hello, 

I am trying to include the FOP-Framework into a Java-Environment and to start the 
conversion inline. But the System.exit exits the whole application. Is there a way to 
have a java Program starting FOP-Konversion not from the CommandLine?


in the class org.apache.fop.apps.CommandLineStarter there is a 
System.exit(0) 
in the run-method, why ?
Is it a problem to add a FileOutputStream and to close the stream in the finally 
method instead of using the exit?

Thanks for help

public void run() throws FOPException {
        String version = Version.getVersion();

        log.info(version);

        XMLReader parser = inputHandler.getParser();
        setParserFeatures(parser);

        Driver driver = new Driver();
        driver.setLogger(log);
        driver.setBufferFile(commandLineOptions.getBufferFile());

        if (errorDump) {
            driver.setErrorDump(true);
        }

        FileOutputStream fos = null;
        
        try {
            driver.setRenderer(commandLineOptions.getRenderer());
            //driver.setOutputStream( new FileOutputStream(
            //                          commandLineOptions.getOutputFile()));
            fos = new FileOutputStream(commandLineOptions.getOutputFile());
            driver.setOutputStream(fos);
            driver.getRenderer().setOptions(
              commandLineOptions.getRendererOptions());
            driver.render(parser, inputHandler.getInputSource());
            //
            //System.exit(0);   Do not stop here in the finally part the file will be 
closed
           //

            if (e instanceof FOPException) {
                throw (FOPException) e;
            }
            throw new FOPException(e);
        }
        finally {
          try {
            if (fos != null) fos.close();     // closing the stream
          }
          catch (IOException e) {
            throw new FOPException(e);
          }  
        }
    }
