How to simply write bean objects to String

This utility provide ability to write objects to string. Example says everything:

public class Person {

    private PersonName name;
    private Integer age;

    public static class PersonName {

        private String firstName;
        private String lastName;

        public PersonName(String firstName, String lastName) {
            this.firstName = firstName;
            this.lastName = lastName;
        }

        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

        public String getLastName() {
            return lastName;
        }

        public void setLastName(String lastName) {
            this.lastName = lastName;
        }
    }

    public Person(PersonName name, Integer age) {
        this.name = name;
        this.age = age;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public PersonName getName() {
        return name;
    }

    public void setName(PersonName name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return StringUtils.objectToString("person", this);
    }
}

Then we call:

    public static void main(String[] args) {
        System.out.println(new Person(new PersonName("Astar", "Sheran"), 2009));
    }

and output is:

person.age = 2009
person.name = new Person$PersonName()
person.name.firstName = Astar
person.name.lastName = Sheran

XDXF Parser library

I created small library to parse dictionaries stored in XDXF format. API is event based and you can listen to events (dictionary, article) while parser is parsing.
Whole dictiary is not loaded to memory by default, so you can parse large dictionary with small memory footprint. Project is hosted on kenai.com. Binary packages will be available soon, but source code is available in kenai browser.

API usage example:

import eu.hlavki.xdxf.parser.DefaultXDXFParser;
import eu.hlavki.xdxf.parser.ParseException;
import eu.hlavki.xdxf.parser.XDXFParser;
import java.io.IOException;
import java.io.InputStream;

public class Sample {

    public static void main(String[] args) {
        InputStream in = null;
        try {
            XDXFParser parser = new DefaultXDXFParser();
            DictionaryListener listener = new DictionaryListener();
            parser.addXDXFEventListener(listener);
            in = Sample.class.getResourceAsStream("/test-dict.xdxf");
            long startTime = System.currentTimeMillis();
            parser.parse(in);
            long endTime = System.currentTimeMillis();
            System.out.println("Dictionary: " + listener.getDictionary());
            System.out.println("Word Count: " + listener.getArticleCount());
            System.out.println("Parse time: " + (endTime - startTime) + " ms");
        } catch (ParseException e) {
            e.printStackTrace();
        } finally {
            try {
                if (in != null) in.close();
            } catch (IOException e) {
                // should never happened
            }
        }
    }
}

Listener sample code:

import eu.hlavki.xdxf.parser.event.XDXFArticleEvent;
import eu.hlavki.xdxf.parser.event.XDXFDictionaryEvent;
import eu.hlavki.xdxf.parser.event.XDXFEventListener;
import eu.hlavki.xdxf.parser.model.XDXFDictionary;

public class DictionaryListener implements XDXFEventListener {

    private int articleCount = 0;
    private XDXFDictionary dictionary;

    public void onDictionary(XDXFDictionaryEvent evt) {
        this.dictionary = evt.getSource();
    }

    public void onDictionaryChange(XDXFDictionaryEvent evt) {
        this.dictionary = evt.getSource();
    }

    public void onArticle(XDXFArticleEvent evt) {
        articleCount++;
    }

    public int getArticleCount() {
        return articleCount;
    }

    public XDXFDictionary getDictionary() {
        return dictionary;
    }
}

Native2Ascii plugin for netbeans 6.5

After some time of finding myself I am back... 2 days ago my friend and colleague ask me if I know about netbeans feature to convert native characters to ASCII. Same as native2ascii command line but integrated in netbeans editor. Quick answer in my mind: There has to be some plugin, so UTFG... After googling by myself I found only this one. It looks well, but there is no integration with netbeans editor.
So what I did? I wrote plug-in according to my vision. I know it's not good approach to use native characters in java source at all. Better idea is using properties bundles. But sometimes it's OK, when you want to write some small piece of code which is used only by yourself.
Some screenshots:

1. You can use java editor hint:

2. Or just press CTRL+SHIFT+A or right mouse click on selected text:

3. and result is:

You can download this plugin here. Sources can be found in project site.

Rohace in latest summer days 2008

Trip to West Tatras during nice weekend in village Veličná.

I am a netbeans fan, so what...

Time ago I read some blogs about ftp support for php projects in netbeans. I was thinking... Why ftp only? Where's support for SFTP and other protocols? It should be great to have an abstract API for remote file systems and lot of implementations for other protocols. So I started to look into netbeans sources. I found remotefs project in contrib repository. I was thinking: "it's great to see this. Netbeans for PHP must use this". So I started implementation of SFTP protocol. When I was in half of my work I looked into sources of netbeans php modules.
And what I discover? It uses own implementation of FTP protocol. Hmmm, so what now???

Because my primary targer was php module, I didn't know why should I continue write this plug-in. So I decided to rewrite remotefs API and it's implementation to more abstract level because it looks like it's tightly coupled with FTP protocol implementation.

Now I am releasing first alpha quality release. Maybe this is good starting point for integration of this plug-in into existing netbeans features...

You can download it here.
If you are interested in sources are available via mercurial repository.

PS: These modules uses same namespace (package) as mentioned project remotefs in main/contrib. So don't install this modules when you already have it installed.
