Hello Raman,
yes, the following code works for me:
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.PrintWriter;
import java.io.Serializable;
import java.io.StringWriter;
/**
* Utility class to serialize and deserialize <code>java.lang.Throwable</code>,
needed because JAXB cannot map Throwable
* to XML on account of the non-serializable stack trace array.
* @author sml
* @version 3.0
*/
public class ThrowableWrapper implements Serializable
{
private static final long serialVersionUID = 7112569161595756136L;
private String stackTraceString;
private byte[] throwableBytes;
public ThrowableWrapper()
{
}
public ThrowableWrapper( Throwable t ) throws IOException
{
// write Throwable to byte array
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream( baos );
oos.writeObject( t );
throwableBytes = baos.toByteArray();
// as a convenience also save the stack trace as a string
StringWriter s = new StringWriter();
PrintWriter p = new PrintWriter( s );
t.printStackTrace( p );
stackTraceString = s.getBuffer().toString();
}
public Throwable getThrowable() throws IOException, ClassNotFoundException
{
ByteArrayInputStream bais = new ByteArrayInputStream(
throwableBytes );
ObjectInputStream ois = new ObjectInputStream( bais );
Object t = ois.readObject();
return (Throwable) t;
}
// accessors for the properties so that JAXB can unmarshal the data into the
// bean (wrapper).
public String getStackTraceString()
{
return stackTraceString;
}
public void setStackTraceString( String stackTraceString )
{
this.stackTraceString = stackTraceString;
}
public void setThrowableBytes( byte[] throwableBytes )
{
this.throwableBytes = throwableBytes;
}
public byte[] getThrowableBytes()
{
return throwableBytes;
}
}

Subject: RE: Throwable as method argument causes exception
Hi Sebastian,
Is this solution finally working? I am
curious to know what is the working solution. Because, I too have similar
situation, but currently I am passing as a String and recreating exception on
client side. I know this is hack.
Regards
Raman

You will have to add the setters for the properties so that JAXB can unmarshal
the data into the bean (wrapper).
