Do you mean?

java -jar my.jar > /tmp/mylog.log 2>&1

(Or use 'tee' if you want it in the log file and still on the console

I am not able to capture console errors  to an log file

public class MIDSkipPolicy implements SkipPolicy {

	
	private static final Log log = LogFactory.getLog(MIDSkipPolicy.class);

	private Integer skipLimit = null;

	@Override
	public boolean shouldSkip(Throwable throwable, int skipCount)
			throws SkipLimitExceededException {
		
		StringBuffer stringBuffer = new StringBuffer();
		
		if (throwable instanceof FlatFileParseException) {
			int linenumber = ((FlatFileParseException) throwable).getLineNumber();
			String input = ((FlatFileParseException) throwable).getInput();
			
			stringBuffer.append("Parsing exception encountered on line #" + linenumber + "; input = " + input);
			log.error(stringBuffer.toString());
		} else {

			stringBuffer.append("Exception thrown causing record to be skipped: ");
			stringBuffer.append(throwable.getMessage());
			log.error(stringBuffer.toString());
			log.debug(throwable);
		}
		
		if (getSkipLimit() <= skipCount && getSkipLimit() > 0) {
			SkipLimitExceededException skipLimitExceededException = new SkipLimitExceededException(skipCount, throwable);			
			log.error(skipLimitExceededException.getMessage());			
			log.debug(skipLimitExceededException);
			
			throw skipLimitExceededException;
		}
		
		return true;
	}

	public int getSkipLimit() {
		return skipLimit;
	}

	public void setSkipLimit(int skipLimit) {
		this.skipLimit = skipLimit;
	}
}

Adding try catch block  but it is not  able the  capture error to log files.........
where is the issue ......... Any right comments are highly appreciable............

try {
		        logger.setLevel(Level.INFO);

} catch (Exception ex) {
		         // Log the stack trace
		         logger.(Level.SEVERE, ex.getMessage(), ex);
		      }

That looks like the badly-documented java.util.logging. If so, you can specify the location of log files with the logging.properties file, the location of which itself you can specify as a jvm property
