Parsing Ofx file with java

Question

I am currently trying to read an ofx file with java. But I get the following error: Unhandled exception type FileNotFoundException (for the 2nd line). I am using OFx4j. Could you please give me some tips on that one?

Here is the code I have written so far:

String filename=new String("C:\\file.ofx");
    FileInputStream file = new FileInputStream(filename);
    NanoXMLOFXReader nano = new NanoXMLOFXReader();

    try
    {
        nano.parse(stream);
        System.out.println("woooo It workssss!!!!");
    }
    catch (OFXParseException e)
    {
    }

Thanks for your comments, I made some changes:

String FILE_TO_READ = "C:\\file.ofx";


    try
    {
        FileInputStream file = new FileInputStream(FILE_TO_READ);
        NanoXMLOFXReader nano = new NanoXMLOFXReader();


        nano.parse(file);
        System.out.println("woooo It workssss!!!!");
    }
    catch (OFXParseException e)
    {
        System.out.println("Message : "+e.getMessage());
    }
    catch (Exception e1)
    {
        System.out.println("Other Message : "+e1.getMessage());
    }

But now I am getting this:

Exception in thread "main" java.lang.NoClassDefFoundError: net/n3/nanoxml/XMLParseException at OfxTest.afficherFichier(OfxTest.java:31) at OfxTest.main(OfxTest.java:20) Caused by: java.lang.ClassNotFoundException: net.n3.nanoxml.XMLParseException at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 2 more

I am trying to figure it out. I believe it can't find the XMLParseException. But I am not sure.

Answer 1

The second problem that you're encountering: "Exception in thread "main" java.lang.NoClassDefFoundError: net/n3/nanoxml/XMLParseException" means that you haven't included the NanoXML library from here: http://devkix.com/nanoxml.php

You will also need the Apache Commons Logging library, as NanoXML appears to be dependent on this. Available here: http://commons.apache.org/logging/download_logging.cgi

Answer 2

This means that you are not catching FileNotFoundException. Also although this is not relevant to your error message but as best practice you should always close you file stream in the finally block like I have below. There is also no need to do to new String() on the file name either.

Add this catch block for the FileNotFoundException:-

    String filename = "C:\\file.ofx";
    FileInputStream file = null;
    NanoXMLOFXReader nano = null;
    try
    {
         file = new FileInputStream(filename);
         nano = new NanoXMLOFXReader();
        nano.parse(stream);
        System.out.println("woooo It workssss!!!!");
    }
    catch (OFXParseException e)
    {
        e.printStackTrace();
        throw e;
    }catch (FileNotFoundException e){
        e.printStackTrace();
        throw e;
    }finally{
        if(file!=null){
           file.close();
        }
    }
