Java -=- How to copy file using Apache IOUtils

Here is a code snippet that explain how to copy a file using IOUtils. You can get Apache IOUtils at http://commons.apache.org/io/download_io.cgi

InputStream in = null;
OutputStream out = null;

try {
    // Ensure folder is created
    FileUtils.forceMkdir(new File("/Users/yann/myfolder"));

    in = new FileInputStream(new File("/Users/yann/from.txt"));
    out = new FileOutputStream(new File("/Users/yann/myfolder", "to.txt"));

    IOUtils.copy(in, out);

} finally {
    IOUtils.closeQuietly(in);
    IOUtils.closeQuietly(out);
}

JAD Java Decompiler Download Mirror

Since http://www.kpdus.com/ is not available anymore, JAD is now hard to find.

Here's a mirror containing all the versions of JAD. This article is a copy of Tomas Varaneckas's site (http://www.varaneckas.com/jad).

• Jad 1.5.8g for Windows 9x/NT/2000 on Intel platform (238600 bytes).
• Jad 1.5.8g for Mac OS X 10.4.6 on Intel platform (170707 bytes, compiled by GCC 4.0).
• Jad 1.5.8e for HP-UX 11.x (293214 bytes).
• Jad 1.5.8e for Linux on Intel platform (214917 bytes).
• Jad 1.5.8e for Linux (statically linked) (389972 bytes) - take this version if the one above crashes or displays the "seek error" message.
• Jad 1.5.8d for OS/2 (288717 bytes) - OS/2 version was cross-compiled on Windows using EMX and RSXNT packages, therefore it requires EMX runtime (EMX.DLL should be enough).
• Jad 1.5.8c for FreeBSD 4.0 (322311 bytes) - statically linked.
• Jad 1.5.8c for OpenBSD 2.7 (334499 bytes) - statically linked.

• Jad 1.5.7b for Mac OS X (Rhapsody 5.3) on PowerPC platform (372317 bytes).
• Jad 1.5.7a for Solaris 7 on Intel platform (252582 bytes) - try the version for Solaris 8 instead.
• Jad 1.5.5.3 for AIX 4.2 on IBM RS/6000 platform (360970 bytes).

 

Installation

Unzip jad.zip file into any appropriate directory on your hard drive.
This will create two files:

• an executable file named 'jad.exe' (Windows 9x/NT/2000) or 'jad' (UNIX)
• README file 'Readme.txt', which contains the short user's manual

For UNIX users: make 'jad' executable: chmod a+x jad
No further setup is required.

[RSA] Install Cicso AnyConnect on Mac OS X Snow Leopard

Hi!

There is a bug with the version of Cisco AnyConnect 2.3 that made impossible to install the VPN client on Mac OS X Snow Leopard.

To be able to install it, we must download a newer version (2.4 and later).

You can get the client by connecting to the Cisco Web Site (http://www.cisco.com/cisco/software/navigator.html) and download it. You need a username / password.

If you do not have an account on the Cisco's Web Site, you can download a copy of the software here:
at  http://unf.net/snowleopard/anyconnect-macosx-i386-2.4.0154-k9-BETA.zip


Download and install the client. After that, connect yourself to the RSA servers. The AnyConnect client will be automatically updated.

You must be ready to use AnyConnect Client with Snow Leopard.

ExtJS -=- Converting a timestamp value to a valid date when loading a FormPanel (DateField)

I've got a problem today. I was trying  to load a record that contains a timestamp field that comes from a Rails application (with PostgreSQL DB).

The FormPanel refuse to load the date value in my DateField component. I've discovered that it was because the DateField did not recognize the date because it was a timestamp.

In order to be able to set the date's value, we need to format the timestamp as a date when loading the FormPanel.

Here's how to do this.

Generated JSON used to load the FormPanel

{
     success:true, 
     data: {
          start_date: \"Tue Apr 12 20:06:11 UTC 2011\", 
          id: 4, 
          app_id: 2, 
          version: \"1.2.3\", 
          message: \"test msg\", 
          active: true
     }
}

Add this code to your FormPanel

form.getForm().on({
    actioncomplete: function(form, action) {
        if (action.type === 'load') {
            if (action.result.success) {
                var date = new Date(action.result.data.start_date);

                form.setValues({
                    start_date: date.format('Y-m-d')
                });
            }
        }
    }
});

When loading, the value of the date will be converted from a timestamp to a valid date and the DateField will recognize the value.

ExtJS -=- Wait message while loading a store

Hi!

To display a loading message while a store is loading, simply add this line of code...

// Store Definition
var objectAStore =  new Ext.data.JsonStore({
    url: '/objecta/json_dropdown_list',
    root: 'Records',
    totalProperty: 'Total',
    fields:[
    {
        name: 'id'
    },
    {
        name: 'name'
    }
    ]
});

// Loading Mask
new Ext.LoadMask(Ext.getBody(),{msg:'Loading data...', store: objectAStore});

If you want a loading mask for a grid panel, simply set GridPanel's property "loadMask" to true

Mac OS X -=- Installing Java 1.4 on Snow Leopard

By default, Snow Leopard does not include Java 1.4 anymore. All the Java 1.4 softlinks points to the Java 1.6 library. If you want to install Java 1.4, you must install it manually.


In the terminal: 


Get the java 1.4.2 that was included in 10.5 "leopard" and unpack

cd /tmp/
curl -o java.1.4.2-leopard.tar.gz http://icebergsofts.com/static_content/java.1.4.2-leopard.tar.gz
tar -xvzf java.1.4.2-leopard.tar.gz

Move it to your System java folder (password needed)

sudo mv 1.4.2 /System/Library/Frameworks/JavaVM.framework/Versions/1.4.2-leopard

Tell OS X that java 1.4.2 actually is java 1.4.2

cd /System/Library/Frameworks/JavaVM.framework/Versions/
sudo ln -s 1.4.2-leopard 1.4.2
sudo ln -s 1.4.2 1.4

Open Java Preferences

open "/Applications/Utilities/Java Preferences.app"

Change the properties to use Java 1.4.2 32-bit by default:
