[DataVision-users] Help using DataVision from Java

[E D. <mag...@gm...>]

Hi,

I have recently discovered DataVision and it seems to be a great tool
for making reports. I am using it in an assignment for school.
I can create a report fine in the interface, and it runs and displays
the results I want. However, I am trying to get it to run from a Java
application.
I have followed the instructions on this page: [
http://datavision.sourceforge.net/DataVision/embed.html ] but it still
wont work.

The following compiles fine, but produces nothing at runtime (not even
an Exception or some kind of error).

    public void doReport() {
        Report myReport = new Report();
        try {
            /*DatabaseConnection.getConnection() returns a
java.sql.Connection object.
              The connection has already been established prior to
this being called.*/
            myReport.setDatabaseConnection(DatabaseConnection.getConnection());

            File reportFile = new File("testReport"); //the file
testReport is in the current working directory
            myReport.read(reportFile);

            OutputStream out = new FileOutputStream("test.pdf");

            myReport.setLayoutEngine(new PDFLE(out));
            myReport.runReport();

        } catch (Exception ex) {
            MessageBox.showError(null, ex.toString()); //MessageBox is
just a wrapper around JOptionPane.showDialog()
        }
    }

The file "test.pdf" does not appear, and no kind of error or Exception
is thrown to indicate a read/write issue.
Would somebody be able to point me in the right direction?

Also, as a sidenote, the Javadoc for the DataVision library doesnt
show up in NetBeans. I found this odd, because the source contains
Javadoc.

Cheers,
Erin
