Log Files with EJB

Can we have text file where my EJB write my log information in my own format. If yes how does it happen in EJB Container. Where do I need to place my file.
thank you in advance?

Check out AspectJ, www.aspectj.org - they have some really interesting options.

Creating library file with ejb

Can anyone suggest me the process by which we can create a library file with ejb? I am new to the ejb environment and i need some guidance regarding this.

Could you be more specific about what you mean by library file? Are you asking about how to package classes used by ejb components outside of the ejb-jar itself?

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)
              logger.log( Level.WARNING, e.getMessage(), e );
         catch (Exception e)
              logger.log( Level.WARNING, "Exception", e);
}But when I use this class...
import java.io.File;
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.FileHandler;
import java.util.logging.Handler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.XMLFormatter;
public class TraceUtils
public static Logger logger = Logger.getLogger("log");
public static void initLogger(String ApplicationName) {
    Date date = new Date();
    DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
    String dateStr = dateFormat.format(date);
    String logFileName = dateStr + ApplicationName + ".log";
    Handler fh;
    try
      fh = new FileHandler(logFileName);
      fh.setFormatter(new XMLFormatter());
      logger.addHandler(fh);
      logger.setLevel(Level.ALL);
      logger.log(Level.INFO, "Initialization log");
    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?

Do we need to format data and log files with 64k cluster size for sql server 2012?

Do we need to format data and log files with 64k cluster size for sql server 2012?
Does this best practice still applies to sql server 2012 & 2014?

Yes. The extent size of SQL Server data files, and the max log block size have not changed with the new versions, so the guidance should remain the same.

Getting empty log files with log4j and WebLogic 10.0

Hi!
I get empty log files with log4j 1.2.13 and WebLogic 10.0. If I don't run the application in the application server, then the logging works fine.
The properties file is located in a jar in the LIB folder of the deployed project. If I change the name of the log file name in the properties file, it just creates a new empty file.
What could be wrong?
Thanks!

I assume that when you change the name of the expected log file in the properties file, the new empty file is that name, correct?
That means you're at least getting that properties file loaded by log4j, which is a good sign.
As the file ends up empty, it appears that no logger statements are being executed at a debug level high enough for the current debug level. Can you throw in a logger.error() call at a point you're certain is executed?

OMBPlus: masking usernames / passwords in log files with ********?

Hi all,
Subjects says it: how to hide username and password in OMBPlus logs.
Any ideas...?
Br: Ykspisto

I don't use default OMB+ logging for this reason, plus I often want more robust logging. I also built a wrapper for executing OMB+ statements to simplify my exception handling in my main scripts. By catching both the return string from a statement as well as the exception strings, I keep full control over what gets logged.
HEre is the meat of my main library file:

Merging Log Files with same name

Hello,
I have log files with same name 00000000.jdb (because created at different machines). I would like to merge data stored in these two files.
I tried below approaches which do not work:
1. rename one of the files -> doesn't work as file header has file name info which doesn't match with renamed value
2. db dump/load -> dump and load works without error. (i have to dump Entity related Database and Format related Database -- from -l option) However when i try to read the file, it gives error.
Exception in thread "main" com.sleepycat.je.EnvironmentFailureException: (JE 5.0.103) Catalog could not be refreshed, may indicate corruption, errorFormatId=52 nFormats=51, . UNEXPECTED_EXCEPTION: Unexpected internal Exception, may have side effects.
I am using EntityStore and thus Annotated Entities.
Does any one has any insights?
Thanks.

Yuvaraj,
As you discovered, it is not possible to use .jdb files from one environment in a different environment. The .jdb files use an internal format with relationships between files that form the Btree.
I'm glad to hear you were able to use DbDump and DbLoad successfully.

Analzing log files with external tools?

Hi,
is there any way to use web analytics software like Webtrends with EP? In other words, does EP produce
an access log file with date, URL, user, referrer,
etc.?
Thanks in advance,
Stefan.

Thanks for the hint. Apparently httpaccess\responses.0.trc contains log entries that look very familiar to something an ordinary web server produces, which is good.
A simple perl script could transform the logfile (date, etc.) into a format that a Web statistics tool on the market (e.g. WebTrends) could use.
The SAP built-in reports are not something that drives a marketing department wild.
Thanks,
Stefan

Nginx client_ip in log file, with ssh -R Port forwarding

Hi, everyone!
First, I run a nginx server M1 (in my offce) behind a router R1 and M1's IP addr is 192.168.5.126. I set nginx's log format like this:
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
After that, I will get the correct client ip in the access log.
192.168.5.88 - - [21/Apr/2015:11:12:47 +0800] "GET /js/date.js HTTP/1.1" 200 403 "http://192.168.5.126/" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36" "-"
Then, I want to visit M1 outside (in the campus) . Unfortunately, I can do nothing with the router R1. But I have a router R2 whose framework is OpenWrt and its IP 222.xx.xx.xx can be visited by anyone who has logged into the campus network.
Then I wrote a autossh service to do that:
[Unit]
Description=AutoSSH service for local port 80 forwarded to 222.xx.xx.xx:80
# place this in /etc/systemd/system/, than enable this.
After=network.target
Requires=nginx.service
After=nginx.service

Yeah, It works! BUT BUT when someone visits 222.xx.xx.xx, I lost the the client ip in nginx log file. That would always be 127.0.0.1, why?
127.0.0.1 - - [27/Apr/2015:00:34:07 +0800] "GET /static/mathjax/MathJax.js?config=TeX-AMS_HTML HTTP/1.1" 304 0 "http://222.xx.xx.xx:808/url/jakevdp.github.com/downloads/notebooks/XKCD_plots.ipynb" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:37.0) Gecko/20100101 Firefox/37.0" "-"
After ``ssh -R Port forwarding``, client ip is lost?
If so, what should I use to replace ``ssh -R``?

It seems there is a port forwarding configuration trouble with you modem.
When you access from the WAN or from the LAN, you don't enter in you modem the same way, so the behavior is different.
It seems that the port 22 of your modem is not directly forwarded to your server. The modem itself asks you a login/password. The key-pair authentification is between laptop and server. The modem itself is not recognized during this authentification.
Don't touch your ssh-config. It's OK since it was working for monthes before you change your modem.

Files with .ejb extension

Hi,
I am using the <javadoc> task in an Ant build file. I have several EJB files with th extension .ejb that I want to have included in my javadocs.
I have the following code:
<target name="javadoc" description="Build Java Documentation">
 <javadoc destdir="${doc.dir}">
 <fileset dir="src">
 <include name="**/*.ejb" />
 </fileset>
 </javadoc>
</target>However, when I run this I get the following error:
[javadoc] javadoc: Illegal package name: "C:\src\com\test\ejb\CommandInputEJB.ejb"I do need the .ejb file extension for another tool to work (Ejbgen). Is there a way to get this working?
Thanks in advance for any help!

Hi Arjun
I'm still learning all of this myself with Ant, but looking at your script, it does not appear to be complete. I understand that you need to have certain tags included. The Ant task documentation gives good information, but in brief, in the list of parameters, the required options are indicated. Your script as a minimum, must include either 'sourcepath', 'sourcepatheref', or 'sourcefiles' and you then must include '<d>destdir' (which you already use).
You can find the documentation here:
http://ant.apache.org/manual/CoreTasks/javadoc.html
I have never included external files such as the EJB ones you are using, but I have written my own script for generating JavaDoc HTML output. Feel free to use it if it helps.
It uses an external file for the package list (sourcepath), called from the property:
 <property name="JDOCSOURCELIST" value="JDOCSourceList.properties" /> 
This is the same as the -sourcepath option of the standard JavaDoc docelt. It is formatted:
<code>
com.supersaus.server
com.supersaus.server.factories
\\\\S5\\Documentation\\com\\supersaus\\common\\Association.java
\\\\S5\\Documentation\\com\\supersaus\\common\\CData.java
</code>
Other properties used in the script are:
<code>
<property name="JDOCDIRECTORY" value="JavaDocOutput" />
<property name="SOURCECODEROOT" value="\\\\S5\\Documentation" />
<property name="STYLESHEET" value="./stylesheet.css" />
<property name="BOTTOM" value="Supersaus 2004" />
<property name="DOCTITLE" value="Supersaus Common Files" />
<property name="LINK" value="http://java.sun.com/j2se/1.4.2/docs/api" />
<property name="OVERVIEW" value="doc-files\\Saus_Overview.htm" />
</code>
The main ant target is built up as follows:
<code>

<target name="BuildJavaDoc">
<splash/> 
<echo message="Please wait whilst the document is generated into the folder ${JDOCDIRECTORY}" />
 
 <javadoc destdir="${JDOCDIRECTORY}"
 sourcePath="${SOURCECODEROOT}"
 packageList="${JDOCSOURCELIST}"
 maxmemory="180M"
 stylesheetfile="${STYLESHEET}"
 bottom="${BOTTOM}"
 Doctitle="${DOCTITLE}"
 Windowtitle="${DOCTITLE}"
 Overview="${OVERVIEW}" >
 <Link href="${LINK}"/>
 </javadoc>
</target>
</code>
Hope all this helps?
Best wishes and good luck

One Log File With Tomcat

I am trying to figure out how to get all of my logging to use one log file. Currently when I start tomcat as a service it writes to stderr.log, stdout.log as well as a log file I have configured using Log4j. I would like all logs including startup/shutdown logs that are currently going to stdout.log/stderr.log to go to the file I write to using Log4j.
If I start tomcat using catalina.bat it doesn't do this (bc it writes to the console window) but I would like to send all those startup/shutdown messages to the log that Log4j uses if I start tomcat as a service.
Any help would be appreciated.

That doesn't really help, because I've got Log4j already running. It looks like there is no easy solution to this. I'm left with choosing one of the three options below.
1) Configure a <Logger> element for the Context that catches any logging not sent to the Log4j log file. This means I would have a stdout.log, stderr.log, log from the <Logger> element, and a log for Log4j. That's a lot of log files...
2) Not configure a <Logger> element for the Context. This means any logging not sent to the Log4j file will go to either stdout.log or stderr.log. Those files could get big and aren't rotated like my Log4j file. Not exactlly ideal either.
3) Don't install Tomcat through the .exe file. Unpackage it, set the environment variables, and set it up as a serivce through a script such as the one mentioned at http://weblogs.java.net/blog/simongbrown/archive/2003/09/installing_tomc.html setting the same file that Log4j uses for the -out and -err parameters. This means that all logging (startup/shutdown) will go to this one log file. But it also means messing with the install (deviating from the .exe) which scares me a little.
Unless someone has a better idea...I guess it's one of the three above.
Thanks,
Jim

Cannot Display Log File with Palm E2 and Palm Desktop 4.1.4.

I finally got the Palm Desktop 4.1.4 which works okay with Vista. I have the Palm Tungsten E2. When I sync, and when it indicates that there were some duplications, etc. and do I want to view the HTM log file, I click on view log, and it comes up unable to display/find the page! Does anyone know what is going on?

This question was solved.
View Solution.

Thanks for replying PALM_LOVER!
Sometimes, yes, sometimes no. When I first sync-ed today, I got the prompt, and when i clicked on VIEW LOG, it took me to a web page that said "FILE NOT FOUND "("Firefox can't find the file at /C:/Program Files/palmOne/Stephe/HotSyncLog.htm.") I re-sync-ed and did not get the prompt.

Create different log file with different schema by spool

Hello,
I want to know a way to create a different log file depend on different schema
I have two schema on same db server
1) schema kennam/*****/kennam
2) schema koonhey/*****/koonhey
by a way, I want to create a different log file name e.g. kennam.log / koonhey.log on such two schema...
I always run @showbalance; to run showbalance.sql to create that report..
I hope you understand what I talking about (english is not my native language........), anyone could help?
showbalancelog.sql
spool c:\log.log+
spool c:\log.log
select to_char(sysdate,'dd-mm-yyyy hh:mi:ss') from dual;
column com_name format a20;
select cus.tid, cus.com_name com_name, cus.com_balance,
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) sum_invoice,
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) sum_income,
cus.com_balance -
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) +
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) total_balance
from customers cus
order by cus.tid;
spool off

okey I solved on this way, is anyone know another simpler way?
