Serializing org.apache.log4j.Level

Hi,
I'm working with Log4j and I have to serialize an org.apache.log4j.Level that has not an empty constructor but only more static instaces.
Is there a workaround to do this ?
Or How can I use the static instance ?
Thanks,
Bye Luigia

this is my XML file
<java version="1.5.0_08" class="java.beans.XMLDecoder">
<object class="org.apache.log4j.net.SyslogAppender">
<void property="name">
<string>my.syslog</string>
</void>
<void property="SyslogHost">
<string>localhost</string>
</void>
<void property="Facility">
<string>local0</string>
</void>
How can I specify the "Threshold" Property of the SyslogAppender at "INFO" or int value?
The threshold is a org.apache.log4j.Level.

Hi there,
I have another doubt. Im trying to deploy a web application/J2EE. I use JBOSS. Now, after compiling and placing my jar files in the required directory and as i start the JBOSS server I get the following error in the console............
10:11:06,551 WARN [jbossweb] java.lang.IllegalStateException: Servlet class

I just can't seem to figure out whats the problem.
My RequestHandler extends an Abstract Req.Handler which imports javax.* etc etc.
Please suggest a solution.
Thanks,

Did you read this part there:
There is a second possible issue that is specific to the commons-logging and related libraries when used with Integrated WLS and the configuration (which includes ADF) out-of-the-box. Because the commons-logging.jar is apparently in the system classpath, due to the way Java classloader delegation works, any log4j classes at the web application level are not visible to the logger factory by default. As long as this is the case, you may need to add the following to your web-application's WEB-INF/weblogic.xml:
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
What this does is tell the WLS JSP servlet to let web application classes override classes found in the system classloader. Standard Java classloader delegation gives the highest priority to the system classes.

Need help with log4j logging tool (org.apache.log4j.*) to log into database

Hi,
I need help with log4j logging tool (org.apache.log4j.*) to log into database using JDBCAppender. Have look at my logger code and corresponding log4j.properties file stated below. I'm running this program using Eclipse IDE and it's giving me the following error (highlighted in red) at the end:

Org/apache/log4j/Category on OAS 10.1.3 and Jdev 10.1.3.5

Hi,
I am new to ADF and my company is also new to ADF. We are doing how it coudl help us in acclerating the development of custom screens on top of OTM 5.5
I am using OAS 10.1.3. I am getting org/apache/log4j/Category error at the time of deployment causing road block. Plz help...
Below are the steps I followed
1. Stopped OAS
2. Install ADF Installer 10.1.3.5 by extracting files, changing adfinstaller.properties, and running java -jar runinstaller.jar adfinstaller.properties
3. Started OAS
4. OAS never started up as server.xml had an new entry
<application name="datatags" path="../../../BC4J/redist/datatags.ear" start="true" />
<import-shared-library name="oracle.ws.jaxrpc"/>
5. datatags directory was malformed in the sense META-INF/application.xml and other .xml file was not created at all.
6. Since ADF requires only libraries to be available, I removed this 2 enteries and started up the OAS.
7. Started the OAS
8. Copied files from
[$Jdeveloper Home]\jakarta-taglibs
to
[$OC4J Home]\BC4J\lib
the files are:
commons-digester.jar
commons-logging.jar
commons-collections.jar
9. Download and copy apache-log4j-1.2.15 (log4j-1.2.15.jar) to [$OC4J Home]\BC4J\lib
10. I created a simpel ADF Helloworld page.
11.Created a deployment discriptor orion-application and added the following enteries
<imported-shared-libraries>
<remove-inherited name="apache.commons.logging"></remove-inherited>
</imported-shared-libraries>
12. I right clicked on my UserInterface ->New-> Deployment profile -> Created a WAR file
13. Right click the WAR file and deployed to the OAS
14. I got the following deployment error
Wrote EAR file to C:\shobz\SOFTWARES\otm_jdev_10G\jdev\mywork\TestADF\UserInterface\deploy\webapp1.ear

ADF 11g requires JEE 5.0 server.
Oracle Application Server 10.1.3 supports J2EE 1.4.
JDeveloper 11g application won't run on OAS 10.1.3.

Import classes like org.apache.log4j.*

Dear All,
I am studying some programs which use XML parsers in Java to read and write data in XML format.
I am unable to compile the main program as I am unable to import library
org.apache.log4j.Category and org.apache.log4j.PropertyConfigurator
I have downloaded the entire XML pack from your site and unzipped each jar. Many classes have been identified except the ones above.
Please tell me how to get around solving this problem.
Thanks
Ranjan

Those classes are part of jakarta log4J, not the Java XML pack.
You will need to visit http://jakarta.apache.org/log4j/docs/index.html and install log4j to compile/run that program. Or have you already installed it and successfully imported org.apache.log4j.*?
Hope that helps.

How to configue plugins for java like org.apache.log4j.Logger

My application tries to import org.apache.log4j.Logger ,import org.apache.commons.lang.StringUtils
and many such packages of org.
I got downloaded Logger package but could not figue it out how to configure it so that application can find it out through org.apache.log4j.Logger etc directory structure , because the installation instructions they gave there seems to create different directory structure.
Also is there any place where I can get the all packages of org group and cnfiguration tips for them.
Thanks & Regards,

Import problem org.apache.log4j.PropertyConfigurator

Sorry if this is a dumb question but:-
I have entered
import org.apache.log4j.PropertyConfigurator;
into NB5.5 and it says "package org.apache.log4j does not exist".
Am I supposed to download this package or is it on my PCs hard disk somewhere? I've done a file search but failed to find it. Does it come with JDE or JDK? or have I not set up a CLASSPATH variable/parameter?
Please can someone help?
Drew

First check whether you have log4j libraries on your machine.
By Default its not available with JRE or JDK.
If you dont find locally, download it from the apache site.

Org/apache/log4j/Category

Hi,
When I try to run a client problem by using
log4j. It gives me the folllowing error:
java.lang.NoClassDefFoundError: org/apache/log4j/Category
at java.lang.Class.newInstance0(Native Method)
at java.lang.Class.newInstance(Class.java:237)
I am wondering if the above class is still included in log4j-1.2.8.jar
thanks,
Rick

The long answer is, look for yourself. You can look into a jar file with any zip utility program (e.g. Winzip if you are working on Windows). However it happens that I have that jar file on my system and the short answer is, yes.

Log4j level inheritance concept doubt

log.properties file
log4j.debug=true
log4j.rootLogger=ERROR, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%m%n
log4j.logger.logging.basics=WARN, cs3
log4j.appender.cs3=org.apache.log4j.RollingFileAppender
log4j.appender.cs3.layout=org.apache.log4j.PatternLayout

log4j.appender.cs3.MaxFileSize=100KB
log4j.appender.cs3.MaxBackupIndex=1
log4j.additivity.com.durasoft.logging=false
log4j.logger.RAM=INHERITED, B1
log4j.appender.B1=org.apache.log4j.RollingFileAppender

package logging.basics;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;
import org.apache.log4j.BasicConfigurator;
import org.apache.log4j.FileAppender;
import org.apache.log4j.Logger;
import org.apache.log4j.PatternLayout;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.spi.RootLogger;
public class LogBasics
     public static void main(String[] args) throws IOException
          Properties prop = new Properties();
          FileInputStream stream = new FileInputStream("logging\\Resources\\log.properties");
          prop.load(stream);
          PropertyConfigurator.configure(prop);
          Logger temp = Logger.getLogger("RAM");
          RootLogger root = (RootLogger)                     Logger.getRootLogger();
          temp.error("h1i");
          temp.warn("hel1lo");
}Refering to above code and properties file(in bold font), the logger named "RAM" didnt inherit from logging.basics package(which it lies), but inherits only from root, even though level and appenders for logging.basics package is specified in properties file.
I doubt, because according to level inheritance concept, the logger must inherit from parent level(assuming parent is not null).
Here parent ,is logging.basics for LogBasics class,so RAM logger must inherit from logging.basics as logging.basics is defined in properties file.
But,its not happening?Why it is so?
2) also please explain me what getLogger does when configured using property file
Thank you.

I have 3 class class A,B,C in multi level as below the method present in class A should only be accessed in A and B .Should not be visible in C and notaccessible for C class object.Java does not support that in general. In this specific case, if A and B are in the same package, and C is in a different package, and the method in question has package-private access level (not public, private, or protected).
However, if you're doing this, you almost certainly have a design flaw. My guess is you're trying to use inheritance for code sharing, which is not what it's for.

Apache log4j

I need to use logger in my application.
Can anyone give me some ideas how to start.Small introduction will be good and sufficient.
Is apache log4j good or the java.logger?

The core of Apache log4j is the log4j.properties file which you can download from different sites.
This file defines the various way of logging the messages.
After placing this file in the folder where you have the java classes,you need to have the log4j.jar file which provides the API related to this logger.
Then on any java file u can log the message using the logger object.
Ex: Logger log=Logger.getRootLogger();
log.warn("this is warining message");
log.info("this is info message");
Depending on the appender specified on the log4j.properties the log may be displayed on the console or may be printed on the specified file.
Here is the part of log4j.properties file:
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.rootLogger=info, stdout
I think this will help you a lot!

That's a pretty decent error message. Have you eliminated the potential causes which were listed in the message?
