Using log4j in a portlet

I have an example app, Forums, that I downloaded from oracle that uses log4j for debuging and such. I've attempted to implement this as well. It works just fine when I'm running the local OC4J via jDev for testing. When I deploy my app I get the following error in the application.log:

The log4j jar file is being deployed and is located in the /j2ee/OC4J_Portal/applications/IMAPTestClient/IMAPTestClient/WEB-INF/lib directory. This is all that seems to be done in the example app and it works just fine.
Any ideas?

We're having the same issue except we're not running in a portlet. We've verified that the code that was deployed was compiled against OC4J 9.0.2 through JDeveloper 9.0.2. We're running OC4J 9.0.2 on the application server as well.
We've also verified that we have exactly ONE log4j jar file in our entire application server directory structure. However, we still receive the same Verify error. We've tried log4j-1.2.6, log4j-1.2.7 and log4j-1.2.8
Any ideas?
Thanks!

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye

Need Some Help in Using Log4j for logging

Hi
I am using Log4j for logging in my application . i have problem some areas .
I want to rotate my file on basis of Time. means if my log file name format is HH:MM then after every minute new log file should be created , i am using Size based rotation its working fine.
Plz Tell me which propety i used to set my logfile name like DATeFormat
i tried with this Property but failed
log4j.appender.R.File=%d{HH:MM}
Simlarly i dont want to bound BackupSize
log4j.appender.R.MaxBackupIndex=1000
i want that suppose after 2 Mb automatically start new file and there is no upper bound on that
how can i do that or from where i can see all properties of Log4j Thanks

Thanks
But in this case i cannot do Size based rotation
These properties not belong to DialyRolling.. class
log4j.appender.R.MaxFileSize=1KB
log4j.appender.R.MaxBackupIndex=1000
what i want is if file size grow with in one minute i create new file using RollingFileApender and if size doesnt grow in one minute and minute cross then next minute file should be created , how can i acheive both of these

Cost involved in changing the code using log4j.properties to log4j.xml

i have finished my application, and it was done in such a way that logging is done using log4j but it was using log4j.properties file.
now i need to change it to log4j.xml. i need to do this at the earliest. so i need to know the cost involved in it?. do i need to change a lot on my app to read the log4j.xml?. In my app there is a function named getProperties, which actually reads the log4j.properties file.
this is the code of that function
public static Properties getProperties(String filename,String path) throws myException
//InputStream is = null;
FileInputStream is=null;
        Properties props = new Properties();
        //ClassLoader classLoader = ResourceUtil.class.getClassLoader();
        //is = classLoader.getResourceAsStream(filename);
        File catalinaHome = new File(System.getProperty("catalina.home"));
        try {
is=new
FileInputStream(catalinaHome.getCanonicalFile()+path + filename);
} catch (IOException e) {
        if(is == null)
            String message = "Cannot locate property file " + filename + " in the classpath";
            log.error(message);
        throw new myException(message);
        try
            props.load(is);
        catch (IOException e)
            String message = "Error reading property file " + filename;
            log.error(message);
        throw new myException(message, e);
        finally
            try
                is.close();
            catch(Throwable t)
                t.printStackTrace();
        if(props.isEmpty())
            String message = "No properties are defined in " + filename;
            log.error(message);
        throw new myException(message);
        return props;
}and my initialize function is
public static void initialize()
Properties properties=null;
try {
String path="/properties/";
properties=ResourceUtil.getProperties("log4j.properties",path);
} catch (myException e2) {
e2.printStackTrace();
PropertyConfigurator.configure(properties);

1. Restructure log4j.properties into log4j.xml.
thats done
2. Move log4j.xml into a directory that's in the
classpath.
actually i donot understand what does it mean to move in a directory thats in classpath means. i have to use logging in my webapplication running in tomcat. and my log4j.xml has to reside in catalina.home/properties/. My log4j.properties have been residing here and it had worked well woth the previous function. Now what i did is placed the log4j.xml under properties folder. Now tell me what modifications should i make in the above code.
3. Remove any code that explicitly configures log4j
(i.e. the initialize() method) because log4j will
configure itself from any properties file it finds in
the classpath, automatically, the first time it is
called.I prefer not remvoing this function as this function is being called in many of my classes... and we don't have time to edit all...
please help... and excuse me if i asked some blunders.!!!

Problem in using log4j..i'm getting warning!!!

i have been using log4j without any porblems. i have placed the log4j.properties file under classes folder under WEB-INF and it worked.
but now i'm asked to place it under a folder named properties under CatalinaHome. And i came to know tht there is no problem in doing so and i just changed the path in my code.
but now i'm getting the following warnings.. but logging is also going well..
what could be the reson for this warning.
log4j:WARN No appenders could be found for logger (com.servlet.Search
Profile).
log4j:WARN Please initialize the log4j system properly.

Hi
Have not come across a situation to limit the number of records in APD while processing, we have several DTP's extracting quite high volume of data and processing it further. (Including Cumulative & Non-cumulative key figures)
However please be informed that the processing will fail if the query execution runs out of memory due to high volume of data.
Based on the above screen shot it seems to be a warning message but will process the data.

Error in Logging using log4j When deployed in weblogic server

I have deployed an SOAP based web service application as an war file and used log4j propertiers to do application logging .When i tested the application through a JAVA client the log4j log file has all the application log information but when i deployed it in the weblogic server 10.3.3 and tested it through SOAP UI it gives me just "Run time error exception" in the log4j log file(which is returned in the SOAP response) as against the application logs which i need. I have also added <wls:package-name>org.apache.log4j.*</wls:package-name> in the weblogic.xml and also changwed the logging to the log4j logging in the server ( which was perviously JDK logging) .But still it is not returning the complete application error stack trace in the log4j log file(and also in the weblogic command console) I need to get the application error stack trace in the log4j log file ( and also in the console) so it would be easy to debug the code.
Please help me out in doing the same.
thanks in advance

Using Log4J in a Portal Application

I am using Log4J in my portal app, but no log messages are getting printed. Here
is what I am doing -
In a Pageflow I have the following code
public static final String CLASS_ID = MyPageFlow.class.getName() + " - ";
private static Logger logger = Logger.getLogger(MyPageFlow.class.getName());
In the begin method I have -
logger.debug(CLASS_ID+"In Begin Action");
Then in my startWebLogic.cmd I have
set LOG4J=-Dlog4j.config=myconfig\log4j.properties
And I add this to the start line
Here is my log4j.properties file
log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=logs/myspt.log
log4j.appender.R.MaxFileSize=1000KB
log4j.appender.R.MaxBackupIndex=100
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
What could be wrong?
Thanks in advance.

Can I use log4j with a java stored procedure

I have code that resides on the middle tier and on the database. Our company is using log4j for debugging purposes. In order to get my code to work on the database, I have had to remove all the log4j stuff. Has anyone tried to get code that has log4j messages to run on the database? I am not concerned with actual debugging, I just don't want to have to strip this code out if I can avoid it.

Hi Laura,
As far as I know, you have two choices:
1. Load the log4j classes into the database (using the "loadjava" tool).
2. Enable remote invocation of log4j classes via RMI (or similar).
Hope this helps.
Good Luck,
Avi.

Logging using Log4J

Hi,
I want to use Log4J to write to the sap log using a Log4J appender. I followed the tutorial from https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/36085e78-0801-0010-678d-8b4e89ddff3c
but i doesnt work for me. When i check the ear which is deployed to the server, i cant find my log4j.properties file anywhere...i guess that is the problem. I put it in the src folder...i thought it was the correct place, but it doesnt show up in the ear...can anyone help me out?
Much thanks,
Hugo Hendriks

Please don't crosspost. It cuts down on the effectiveness of responses, leads to people wasting their time answering what others have already answered, makes for difficult discussion, and is generally just annoying and bad form.

Using log4j with portal server

Hi,
I am trying to use log4j with Portal server 6.1 using log taglibs from jakarta.
Here is what i've done:
1. copy taglibs-log.jar in /etc/opt/SUNWps/desktop/classes
2. copy taglibs-log.tld in /etc/opt/SUNWps/desktop/default/tld
3. put log statements in JSPs
for example:
<log:debug>This is body content.</log:debug>
<log:debug message="This is attribute content." />
4. /etc/opt/SUNWps/desktop/classes/log4j.properties contains
=========================================
# Sample properties to initialise log4j
log4j.rootCategory=debug, stdout, R
#log4j.rootCategory=debug, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

However no log file is created on my system. I am very new to this and would appreciate if anyone could tell me what more needs to be done to get log records in a file.
Thanks for all your help.
