Undeployed application (EAR) but log file is still opened.

[wongtt78]

Hi,

How to close my log file when I undeploy my application?

Reason for this, when I redeploy my application, my custom rolling appender failed to rename my previous log file. It is due to the file is still open.

But when I shutdown JBoss, and then start it back, my rolling appender manage to rename the log file.

Please refer to my custom rolling appender code below;

public class Log4JRollingFileAppender extends RollingFileAppender {
 private String logDir = PropertiesUtil.getInstance().getString("log4j.log.dir", null);
 private String backupLogDir = PropertiesUtil.getInstance().getString("log4j.backup.log.dir", null);
 private boolean isAppend = PropertiesUtil.getInstance().getBoolean("log4j.is.append", true);
 private String logFileDateFormat = PropertiesUtil.getInstance().getString("log4j.file.date.format", null);

 public void rollOver(){
 Calendar calendar = Calendar.getInstance();
 SimpleDateFormat sdf = new SimpleDateFormat(logFileDateFormat);

 String logFilename = fileName.substring(fileName.lastIndexOf(File.separator), fileName.length());

 String backupLogFilename = backupLogDir + File.separator + logFilename + "." + sdf.format(calendar.getTime()) + ".log";
 File target = new File(backupLogFilename);

 closeFile();
 File file = new File(fileName);

 boolean result = file.renameTo(target);
 if (result){
 System.out.println("Successfully renaming file " + file + " to " + target);
 }else{
 System.out.println("Unable to renaming file " + file + " to " + target);
 }

 try{
 setFile(fileName, false, bufferedIO, bufferSize);
 }catch(IOException ioex){
 LogLog.error("setFile(" + fileName + ", false) call failed.", ioex);
 }
 }

 public void setFile(String filename){
 fileName = logDir + File.separator + filename;

 if(! isAppend){
 File file = new File(fileName);
 if (file.exists()){
 rollOver();
 }
 }
 }

 public String getFile(){
 return fileName;
 }
}

Please help me.

Thank you.

Sincerely
David
