Static code analysis is the analysis of the software that is performed without actually executing the program. The process provides an understanding of the code structure and can help to ensure that the code adheres to industry standards. Static analysis code reviews compare the source code of an application with a set of standards to ensure the source code compiles with those standards, to find unwanted dependencies, and to ensure that the intended structural design of the code is maintained. The main advantage of static analysis is the fact that it can reveal errors that do not manifest themselves until a disaster occurs. Static analysis is only a first step in a comprehensive software quality regime.
Test Post: posting source code
Sample source code
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...!");
}
}

Installing Jadclipse in Eclipse
Today I am going to show you how to install and use Jadclipse. Jadclipse is eclipse plug-in that integrates Jad (Java decompiler) with Eclipse.
- 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.
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.
Reading from CLOB in java through JDBC
Here is a code snippet that I have used to read from a CLOB, Oracle 10g instance.
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);
}
}
