Webdynpro java Log File

Hi All,
I want to check appropriate error log and see what went wrong if my Java Webdynpro application deployment fails.
Can anyone help me out in this?
Regards,
Divya

Hi Divya,
Get hold of DefaultTrace.trc on your server. That will give you the detailed exception for your Web Dynpro application.
You can also use NWA to view the errors. Try accessing

Java log file is duplicated for each run.

Hi all,
I am trying to create a file logger,,Following is part of my coding.
Now I can see the log file being created. However my problem is that every time I run the process the log is appended to the test.log file correctly. But the problem is that it also create test.log.1, test.log.2.. etc files each time the process is run. It will be great if anyone advise me how to eleminate these extra files being generated each time. I need just one log file to be genereted and all the logs to be appended to it.
boolean append = true;
FileHandler handler = new FileHandler(test.log);
SimpleFormatter simpleFormatter = new SimpleFormatter();
handler.setFormatter(simpleFormatter);
logger.addHandler(handler);Thanks in adavance

could some one please help me out on this.

Java.util.logging: write to one log file from many application (classes)

I have a menuapp to launch many applications, all running in same JVM and i want to add logging information to them, using java.util.logging.
Intention is to redirect the logginginfo to a specific file within the menuapp. Then i want all logging from all applications written in same file. Finally, if needed (but i don't think it is), i will include code to write logging to specific file per app (class). The latter is probably not neccessary because there are tools to analyse the logging-files and allow to select filters on specific classes only.
The applications are in their own packages/jars and contain following logging-code:
        // Redirect error output
        try {
            myHandler = new FileHandler("myLogging.xml",1000000,2);
        } catch (IOException e) {
          System.out.println("Could not create file. Using the console handler");
        myLogger.addHandler(myHandler);
        myLogger.info("Our first logging message");
        myLogger.severe("Something terrible happened");
        ...When i launch the menuapplication, it writes info to "myLogging.xml.0"
but when i launch an application, the app writes info to "myLogging.xml.0.1"
I already tried to leave out the creation of a new Filehandler (try/catch block in code above) but it doesn't help.
Is it possible to write loginfo to same specific file?

You should open/close it somehow at every write from different processes.
But I personally prefer different file names to your forced merging, though.

Hi Amit,
Create provider system in NWA -> SOA management -> System Connections. After ping is successful go to NWA -> Application Communication and select your DC and assign the provide system for your service configuration group.
I hope it will works fine as we also did the same.

Hello,
Do you know what the difference between copying a file this way :
** Fast & simple file copy. */
public static void copy(File source, File dest) throws IOException {
FileChannel in = null, out = null;
try {
in = new FileInputStream(source).getChannel();
out = new FileOutputStream(dest).getChannel();
long size = in.size();
MappedByteBuffer buf = in.map(FileChannel.MapMode.READ_ONLY, 0, size);
out.write(buf);
} finally {
if (in != null) in.close();
if (out != null) out.close();
================SECOND WAY============
AND THIS WAY:
// Move file (src) to File/directory dest.
public static synchronized void move(File src, File dest) throws FileNotFoundException, IOException {
copy(src, dest);
src.delete();
// Copy file (src) to File/directory dest.
public static synchronized void copy(File src, File dest) throws IOException {
InputStream in = new FileInputStream(src);
OutputStream out = new FileOutputStream(dest);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
in.close();
out.close();
And which is better? I read up on what each kind of does but still a bit unclear as to when it is good to use which.
Thanks in advance,
JavaGirl

Log File on Desktop From Java HotSpot

A colleague's PC has a log file on the desktop, created 28th October. Its title: 'hs_err_pid3268.log'
Initially we were both concerned since Kaspersky had detected some viruses on his machine on it's nightly scan, however, looking at the log file I'm not sure whether to be worried or not! - It looks legitimate, if a bit odd...
If somebody more knowledgeable could tell me firstly if it's anything sinister and secondly (if not) what may have cause it and whether it's an issue I should investigate on this machine.
Thanks in advance, below is the contents of the text file. (As you can see I'm brand new to these forums, apologies if this is not the correct section for these kind of questions).

Initially we were both concerned since Kaspersky had detected some viruses on his machine on it's nightly scan, however, looking at the log file I'm not sure whether to be worried or not! - It looks legitimate, if a bit odd...
If somebody more knowledgeable could tell me firstly if it's anything sinister and secondly (if not) what may have cause it and whether it's an issue I should investigate on this machine.
Thanks in advance, below is the contents of the text file. (As you can see I'm brand new to these forums, apologies if this is not the correct section for these kind of questions). It is a crash file from the Sun/Oracle VM.
It either got on the desktop because a user manually moved it there or because something is probably misconfigured (at least to me) in the environment.
If you are creating java applications (programming in the java language) then you would need to figure out why the app crashed.
If you are using java applications then you need to tell the vendor that it crashed. And you would not do that here.

Hi!
Here is one method, I have done for that purpose
public synchronized void writeToLog(String message, String levelMsg){
        Locale locale = new Locale("en", "US");
        DateFormat format = DateFormat.getDateTimeInstance(
            DateFormat.SHORT, DateFormat.SHORT, locale);
        Date date = new Date();
        String dateToPrint = format.format(date) + " ";
        try{
            FileOutputStream fo = new FileOutputStream("logfile.log",true);
            PrintWriter pw = new PrintWriter(fo);
            message = dateToPrint + levelMsg + message;
            pw.println(message);
            pw.flush();
            pw.close();
            fo.close();

Export to excel in a webdynpro java app to store a excel file on the server

Hi Experts,
We have a requirement wherein we need to implement the export to excel functionality in a webdynpro java application.
The excel file created in this way should be stored in the server location.
I've implmented the export to excel functionality before but the file used to get stored on to my local desktop. But this time, I want the file to get stored on some portal server location.
Can anyone guide me with the steps for the same?
It would be really great if you can tell me what to change in my code for this new functionality as I've already implemented this functionality to store the file on my local desktop before.
Regards,
Anurag

Java.io.IOException: Failed to rename log file on attempt to rotate logs

Hello.
I'm currently using Weblogic 5.1 SP6 on WinNT Server 4.0 SP6.
I set the weblogic.properties file like this so that the "access.log" will
be rotated every day at midnight.
-- weblogic.properties --
weblogic.httpd.enableLogFile=true
weblogic.httpd.logFileName=D:/WLSlog/access.log
weblogic.httpd.logFileFlushSecs=60
weblogic.httpd.logRotationType=date
weblogic.httpd.logRotationPeriodMins=1440
weblogic.httpd.logRotationBeginTime=11-01-2000-00:00:00
-- weblogic.properties <end>--
The rotation has been working well, but one day when I checked my
weblogic.log, I was getting some errors.
I found out that my "access.log" wasn't being rotated (nor being written,
flushed) after this error came out.
After rebooting WebLogic, this problem went away.
Has anyone clues about why WebLogic failed to "rename log file?"

I'm also getting this error on Weblogic 6.1.1.
It only occurs if you set the format to "extended".
Is there any fix or workaround for this?

Can't create log file with java.util.logging

Hi,
I have created a class to create a log file with java.util.logging
This class works correctly as standalone (without jdev/weblogic)
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.*;
public class LogDemo
     private static final Logger logger = Logger.getLogger( "Logging" );
     public static void main( String[] args ) throws IOException
         Date date = new Date();
         DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
         String dateStr = dateFormat.format(date);
         String logFileName = dateStr + "SEC" + ".log";
         Handler fh;
         try
           fh = new FileHandler(logFileName);
           //fh.setFormatter(new XMLFormatter());
           fh.setFormatter(new SimpleFormatter());
           logger.addHandler(fh);
           logger.setLevel(Level.ALL);
           logger.log(Level.INFO, "Initialization log");
           // force a bug
           ((Object)null).toString();
         catch (IOException e)

         catch (Exception e)

}But when I use this class...

    catch (IOException e)
      System.out.println(e.getMessage());
}and I call it in a backingBean, I have the message in console but the log file is not created.
TraceUtils.initLogger("SEC");why?
Thanks for your help.

I have uncommented this line in logging.properties and it works.
# To also add the FileHandler, use the following line instead.
handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandlerBut I have another problem:
jdev ignore the parameters of the FileHandler method .
And it creates a general log file with anothers log files created each time I call the method logp.
So I play with these parameters
fh = new FileHandler(logFileName,true);
fh = new FileHandler(logFileName,0,1,true);
fh = new FileHandler(logFileName,10000000,1,true);without succes.
I want only one log file, how to do that?

How to Save a file uploaded in WebDynpro Java to Windows server

Hi Guys,
I need to save a file uploaded in WebDynpro Java to a location on one of my companys many internal Window servers but I cannot get it to work. I do not get any errors with the following code, but NOTHING happens... And when I check the folder it is still emply... Please advise. I am particularly not sure about specifying the Path syntax. Also, I do have permission to write to this server. Is it even possible to save to a Windows server from WebDynpro??
//uploaded document already in context...
byte[] file = element.getFileResource();
            //    get the size of the uploaded file
            element.setFileSize(this.getFileSize(file));
            wdContext.currentContextElement().setFSize(this.getFSize(file));
            //    get the extension of the uploaded file
            element.setFileExtension(binaryType.getMimeType().getFileExtension());
            String fName = wdContext.currentContextElement().getFName();
            String fExt = wdContext.currentContextElement().getFileExtension();
            String foName1 = "
server01.w9\Files\P
HRP_Attachments\" + fName + ".pdf";
            File f1 = new File(foName1);
            DataOutputStream dos1;
            dos1 = new DataOutputStream(new FileOutputStream(f1));
            dos1.write(file);
            dos1.flush();
            dos1.close();
Edited by: christiaanp on Sep 30, 2011 8:07 AM

Hi Christiaan,
When specifying the path, make sure you escape the slashes
So, when you would normally use something like
\\server\path\file.txt
in your code you must use it in the form:
String fileName = "\\\\server\\path\\file.txt";
Hope this helps!

Java.util.logging - different log files for different loggers

I'm having trouble configuring Java logging to use different log files for different loggers.
In log4j, I would do this by configuring multiple loggers each with a different appender. But how can I do this with Java (java.util.logging) logging?
This is the basic idea of what I'd like to do:
com.mycompany.app1.level = FINEST
com.mycompany.app1.<log file> = logfile1.log
com.mycompany.app2.level = ALL
com.mycompany.app2.<log file> = logfile2.log
Any suggestions?

This kind of thing?
import java.io.IOException;
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;
public class LogTest {
    private Logger app1;
    private Logger app2;
    public LogTest() {
        // setup loggers
        try {
            // first logger
            app1 = Logger.getLogger("com.mycompany.app1");
            FileHandler filehandler = new FileHandler( "logfile1.log" );
            filehandler.setFormatter(new SimpleFormatter());
            app1.addHandler(filehandler);
            // second logger
            app2 = Logger.getLogger("com.mycompany.app2");
            filehandler = new FileHandler( "logfile2.log" );
            filehandler.setFormatter(new SimpleFormatter());
            app2.addHandler(filehandler);
        } catch(IOException ioex) {
            ioex.printStackTrace();
    private void logStuff() {
        app1.log(Level.SEVERE, "a message for log 1");
        app2.log(Level.SEVERE, "a message for log 2");
