Java Programming

Hello

I am using jasper reports and one of its following method gives me exception:

METHOD

public static Object loadObject(File file) throws JRException
{
if (!file.exists() || !file.isFile())
{
throw new JRException( new FileNotFoundException(String.valueOf(file)) );
}

Object obj = null;

FileInputStream fis = null;
ObjectInputStream ois = null;

try
{
byte[] b=null;

fis = new FileInputStream(file);

BufferedInputStream bufferedIn = new BufferedInputStream(fis);

int i=bufferedIn.read(b);

ois = new ObjectInputStream(bufferedIn);_
obj = ois.readObject();
}
catch (IOException e)
{
throw new JRException("Error loading object from file : " + file, e);
}
catch (ClassNotFoundException e)
{
throw new JRException("Class not found when loading object from file : " + file, e);
}
finally
{
if (ois != null)
{
try
{
ois.close();
}
catch(IOException e)
{
}EXCEPTION Thrown is
}

if (fis != null)
{
try
{
fis.close();
}
catch(IOException e)
{
}
}
}

return obj;
}

EXCEPTION Thrown is

Caused by: java.io.StreamCorruptedException: invalid stream header: D0CF11E0
at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:783)
at java.io.ObjectInputStream.<init>(ObjectInputStream.java:280)
at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:90)





This is thrown on bold underlined line when I try to convert InputStream to ObjectInputStream.


I have tried different files but same exception is thrown.

Any help will be appriciated.
