Using static analysis tools you can analyze the software without having to run the application. These tools come in the aid of the developer to find existing bugs in the code without requiring to put much effort. Good tools are a valuable addition to your toolbox. There are lot of tools available, but I am going to discuss about the FindBugs plug-in for the eclipse and its usage.

FindBugs, what is it?

FindBugs is a static analysis tool that finds coding mistakes by examining java class files looking for potential problems by matching your bytecode against a list of bug patterns.

Installing FindBugs

FindBugs is a tool that is both a stand-alone Java application and an Eclipse plug-in. The stand-alone tool is a command line, ant and a Swing interface. Check the download page for all the download links for all FindBugs versions. Eclipse plug-in for FindBugs require Eclipse 3.3 or later. Use the Eclipse update manager/Install New Software feature to install FindBugs from the FindBugs update site http://findbugs.cs.umd.edu/eclipse

Installing FindBugs plug-in

Start Eclipse. From the Eclipse menu select Help –> Install New Software (My Eclipse version is 3.5 – Eclipse Galileo). If you’re using an older version you might see Software Updates instead of Install New Software.

In the Install window click on the Add button to add a new update site, see the figure below. In the Add Site window enter the FindBugs update site http://findbugs.cs.umd.edu/eclipse in the location text box and click ok.

Simply follow the on screen instructions to install the plug-in. After the plug-in is installed restart the workbench for the changes to take effect.

Configuration

After the installation is finished configure the FindBugs plug-in for your project requirements, priorities, and reporter configurations. From the Window menu select Window –> Preferences. Select FindBugs under Java in the left hand pane.

Running FindBugs

You can run FindBugs against a file, package or entire project. Select the file or package or project in which you want to find bugs, from the right click context menu select Find Bugs –> Find Bugs. Once FindBugs finishes the analysis it will prompt you to switch to the FindBugs perspective.

If it doesn’t switch then from the main menu select Window –> Open Perspective –> Other. From the Open Perspective window select FindBugs and click on ok.

In the Bug Explorer view you can see all the bugs it found (depending on your configurations and reporter priorities). Double click on the bug entry in the bug explorer to open it.

See in the properties view why it thinks its a bug and see the explanation on how to make it better. Make better software by finding the bugs early.

Happy Coding.

public class MyClass
{
   public static void main(String args[])
   {
      System.out.println("Hello World...!");
    }

}

Sample source code initially collapsed

public class MyClass
{
   public static void main(String args[])
   {
      System.out.println("Hello World...!");
    }

}

Sample source code with line highlighting

public class MyClass
{
   public static void main(String args[])
   {
      System.out.println("Hello World...!");
    }

}

Link to my article on how to do this.

• First you require Jad for decompiling java files. You can find a list of mirrors on this site where you can get JAD for various platforms. Download it and unzip into any folder on your hard drive.
• Next download the Jadclipse plug-in jar file from here and place the jar file in your eclipse plugins folder
• Restart your eclipse. If eclipse didn’t recognize the plug-in then launch eclipse with -clean flag.

eclipse -clean

• Configure the path to the Jad executable in eclipse under Window > Preferences… > Java > JadClipse > Path to Decompiler.
• Set the full path of the jad executable, e.g. C:\Program Files\Jad\jad.exe
• Go to Window > Preferences… > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class  files.

file association

Now everything is done. If you want to view the source for any class then simply ctrl+click on that class then the source for that class will be showed in your eclipse editor.

PreparedStatment ps = connection.prepareStatement
("SELECT clobcolumn from clobtable");
ResultSet rs = ps.executeQuery();
while(rs.next())
{
oracle.sql.CLOB clobValue = (oracle.sql.CLOB)rs.getCLOB(1);
BufferedReader reader = new BufferedReader(new
InputStreamReader(clobValue.getAsciiStream()));
String read = null;
StringBuffer buffer = new StringBuffer();
while((read = reader.readLine()) != null )
{
buffer.append(read);
}
}

Eclipse version 3.4
Eclipse SQL Explorer version 3.5.0

Installing using the Eclipse update manager.

• From the Eclipse menu select Help->Software Updates…

• Software Updates and Add-ons dialogue box will be displayed. Select the Available Software tab on the top of the dialogue box. Now Click on the Add Site button on the right hand side of the dialogue box.

• You will be presented with the Add Site dialogue box. Now in the location add “http://eclipsesql.sourceforge.net/” (without quotes) and click ok to close the dialogue box.

• It will search and present you with available software

• Select the features you want to install . In this case select the branch, it will also install the patch and click on the Install button on the top right hand side.
• It will check for dependencies if any and will present to you what all you need to install.

• Confirm the plug-ins you want to install and click next

• Accept the license agreement and click on Finish.

After the installation is done it will ask to restart the workbench, restart the workbench. To open the Eclipse SQL Explorer perspective from the menu select Window->Open Perspective->Other. From the list of perspectives select Sql Explorer and click on ok, you will be switched to SQl Explorer Perspective.

First add these lines to your third party software sources list:

• deb http://ppa.launchpad.net/team-xbmc-hardy/ubuntu hardy main
• deb-src http://ppa.launchpad.net/team-xbmc-hardy/ubuntu hardy main

Then save and reload your repositories, you can also do this from terminal by typing

• sudo apt-get update

Now after the update is finished, you can install xbmc by typing this line in the terminal

• sudo apt-get install xbmc

You can start XBMC by navigating to Applications -> Sound & Video ->XBMC Media Center

I instantly liked this application, the screens, the navigation and everything is good looking. I used another media center application by name Entertainer but I liked XBMC more. Entertainer didn’t work well while compiz is running you need to use matacity for it to display properly. It also created tiny image thumbnails of the contents of the pictures folder in each folder. On the other hand XBMC has no problem loading while compiz is running and views are really good. Though I find one proble with XBMC is playing DVD’s. It loaded the DVD properly but started playing it very fastly as if you press fast forward. It even loaded iso file but same problem with it, it’s playing the movie as if your’re fast forwarding it might be that it is a beta version. It had no problems playing avi files, flv or any other video files it played perfectly well.

Check out some of my screen shots of XBMC.

• Enter the URL of your MySQL Server in the Example URL text box. Something like this “jdbc:mysql://localhost:3306/test”. Here “test” is the database name & enter the url without quotes.
• Click ok to finish the installation of the driver. You should be able to see a green tick mark for the driver we just installed.

Now we will connect to the database.

• From the eclipse menu, select window->Open Perspective->other.

   file and unzip it into your Eclipse installation.
2. Use the Eclipse Update
   Manager.

Installing using the Eclipse Update Manager
