Log4j ejb weblogic

Hi all,
I am using weblogic workshop 8.1 and I have created an EJB. I want to put logging statements in that using log4j.
I modified "workshopLogCfg.xml" and I am able to log the statements. But as this is server configuration file I wont be able to put this in my .ear file.
I want one log4j.xml file in my .ear so that when I ship .ear file, logging is not affected.
I have put log4j.xml in classes and log4j.jar in lib folders of APP-INF of weblogic application. And added following line in META-INF/MANIFEST.MF file
"Class-Path: APP-INF/lib/log4j.jar APP-INF/lib/ APP-INF/classes/"
and also tried
"Class-Path: lib/log4j.jar lib/ classes/"
but both of these approach not working.
Please help me in this.. ITS REALLY URGENT.
Thanks.

It won't work by specifying the classpath in the manifest file of the ear itself.
You will have to specify these files in the Class-Path attribute of manifest files of all the modules (EJB, web, etc.) in your ear file.

Log4j and weblogic workshop server 8.1 ?

Can someone please point out how to setup log4j in weblogic 8.1? I put the log4j.jar file in my server classpath, and in the server startup script I put -Dlog4j.configuration=/path/to/log4.properties in the JAVA_OPTIONS. I can't still get log messages to show in the console. log4j.properties content is:
log4j.rootCategory=DEBUG, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%t] %-5p %c{2} %x - %m%n
In my code, I use the org.apache.log4j.Category class to log messages. For example, static Category cat = Category.getInstance(MyClass.class);
cat.debug("a message");
Is there something I'm doing wrong?
Thanks.

In my setDomainEnv.cmd script which should be located where your workshop domain is installed, I did the following:
# Commented out the following line
@REM set JAVA_PROPERTIES=%JAVA_PROPERTIES% -Dlog4j.configuration=file:%LOG4J_CONFIG_FILE% %CLUSTER_PROPERTIES%
# Set a variable LOG4J_PROPS_FILE to point to the location where my
# log4j properties file is located. NOTE: Full Path required
set LOG4J_PROPS_FILE=/bea/user_projects/domains/workshop/log4j.properties
# Updated my JAVA_PROPERTIES variable to look like the following:
set JAVA_PROPERTIES=%JAVA_PROPERTIES% -Dlog4j.configuration=file:%LOG4J_PROPS_FILE% %CLUSTER_PROPERTIES%
Originally, I had everything setup correctly except for my JAVA_PROPERTIES. Note that the option
-Dlog4j.configuration=file:%LOG4J_PROPS_FILE% %CLUSTER_PROPERTIES% has the word "file:" in it.
What I had that was not working was -Dlog4j.configuration=%LOG4J_PROPS_FILE% %CLUSTER_PROPERTIES%
so I added the file: infront of the LOG4J_PROPS_FILE variable.
Hope this helps.

How can configure .properties file and log4j on weblogic 8.1 SP5

Hi,
I know this is not right forum for post this question.But I hope I'll get my perfect answer here.
I have 2 questions.
1. Where I'll keep my .properties file in weblogic 8.1 SP 5. means I have one own .properties file which is contains some proxy settings and this .properties resides on .war file(now), But I want move this propeties file outside .war file. So Where I'll keep in weblogic 8.1 SP 5.
2. How can we configure log4j in weblogic?
Please reply me.
Regards,
Pattanaik

You can add your.properties and log4j.properties to the classpath cant you?
You just need to edit setEnv.cmd (if i remember correctly) in your weblogic server folder to add the folder containing the properties files to the classpath variable.

Log4J with weblogic Portal 9.2

Can anybody have sample process to configure Log4J with weblogic Portal 9.2?
Sample code alongwith log4jConfig.xml and other required jsr files would be helpful.
I want to store all the log messages to defult weblogic dirctory. i.e base_doman\servers\AdminServer\logs

Do you want your app to log messages using log4j (in which case the setup is no different in WLP than with any other app using log4j, read the log4j docs) or do you want weblogic server messages to be sent to Log4j?

Configuring Log4j for weblogic

Hi
can any one tell me how to configure Log4j for weblogic. I have added the log4j jar files to the weblogic classpath but it does not seem to work..
Thanks and Regards
Narayan

You must make a new directory on the same level with applications directory, place "log4j.properties" file in it, include this directory in the "PRE_CLASSPATH" entry in your startup script and that's all.
Sample line in "startWebLogic.cmd" script
'set PRE_CLASSPATH=%_LIBJARS%;classes'
in classes dir you have "log4j.properties"
Should work,

Trying to look up a LOCAL EJB (Weblogic 8.1)

Hi,
I'm trying to look up a LOCAL EJB (Weblogic 8.1):
try
Context ct = new InitialContext();
Object o = ct.lookup("*ejbSecurityDataLocalHelper*");
catch(...)
I systematically get the following exception:
Caused by: javax.naming.LinkException: Root exception is javax.naming.NameNotFoundException: While trying to look up /app/ejb/AEX_JRK_security_EJB.jar#SecurityDataHelper/local-home in /app/ejb/ISL_MSD_mktdata_general_EJB.jar#MarketDataGeneralManager.; remaining name '/app/ejb/AEX_JRK_security_EJB/jar#SecurityDataHelper/local-home'; Link Remaining Name: 'java:app/ejb/AEX_JRK_security_EJB.jar#SecurityDataHelper/local-home'
Where SecurityDataHelper is the Local EJB, who's called from MarketDataGeneralManager EJB.
I realized that the Weblogic JNDI tree shows a red dot next to the name SecurityDataHelperLocalHome: as the other names are not red, I could guess there was something wrong at deployment... buy deployment logs are OK. When I tryied to test the EJB via the Weblogic console there was a message "The EJB SecurityDataHelper has not been tested successfully. There was a problem determining the JNDI Name of the given bean. "
My ejb-jar.xml looks like this:
<session>
<ejb-name>SecurityDataHelper</ejb-name>

<local>com.MyLocalObject</local>
<ejb-class>com.MyBean</ejb-class>

</session>
and my weblogic-ejb-jar.xml:

What I am doing wrong???

Hi Dan,
As u have targeted the ConnectionFactory to "soa_server1" which is running on "realHostName:7001" ....Can u please check from the AdminConsole that the JNDI name ""jms/b2b/B2BQueueConnectionFactory" is present in the JNDI Tree?
AdminConsole---->Servers---soa_server1 (click) ---> in this general configuration page you will see a link "View JNDI Tree" please ckick on that link to see the JNDI tree entries.
If you dont see any JNDI entry there then it means there is something wrong while setting up the Connection Factory in that case please refer to the Screenshots of Creating and Targeting the Connection Factory: *http://middlewaremagic.com/weblogic/?p=1987*

Log4J with Weblogic Server 10

Hi,
We are migrating an EJB application from Weblogic 8.1 to Weblogic 10.0
In the current configuration, we simply include the following in the server startup script, so as to specify the log4j configuration file, and this takes care of the logging part.
-Dlog4j.configuration=file:<complete file name>
The same thing doesn't work with WL 10. Is there any other (special) way of using Log4j with WL 10?
Note that inside the code, we use commons-logging to get hold of the logger as follows:-
org.apache.commons.logging.LogFactory.getLog(class)
I would be grateful for any help on this.
Thanks in advance.

Neelesh

Application specific logging with Log4j on weblogic 8.1

Hi,
For a few days now, I have been trying to implement application specific logging using Log4j (1.2.x) for my 3 applications running on the same server (8.1.6). All three application war files are generated from same source. I followed the example of Jboss in setting up the Hierarchy for logging using RepositorySelector. In my case Java class which implements RepositorySelector is loaded through ServletContextListener from jar file placed in WEB_INF/lib folder and log4j.properties file is in WEB-INF folder of each application.
Independent logging of each application takes place correctly, if the applications are deployed from console. However logging fails if weblogic is shutdown and restarted, in this case logging takes place from 2 classes only implementing filters of each application. Logging from other classes is not taking place. I am spinning my wheels on this and can't seem to figure out what the issue is.
Thanks for any help...below is the snippet of code
Sohan
public static synchronized void init(ServletContext config, String strLogProperties, String webAppName)
throws ServletException {
if( !initialized ) // set the global RepositorySelector
defaultRepository = LogManager.getLoggerRepository();
RepositorySelector theSelector = new MyRepositorySelector();
LogManager.setRepositorySelector(theSelector, guard);
initialized = true;
Hierarchy hierarchy = new Hierarchy(new RootCategory(Level.DEBUG));
loadLog4JConfig(config, hierarchy, strLogProperties, webAppName);
ClassLoader loader = Thread.currentThread().getContextClassLoader();
repositories.put(loader, hierarchy);
config.setAttribute("hierarchy", hierarchy );
public LoggerRepository getLoggerRepository() {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
LoggerRepository repository = (LoggerRepository)repositories.get(loader);
if (repository == null) {
return defaultRepository;
} else {
return repository;
public void LogInit(ServletContext ctx) throws ServletException {
System.out.println("\n\n---------------Log4jInit---------------\n\n");
String strLogProperties = ctx.getInitParameter("Log4JProperties");
System.out.println("Log4j properties " + strLogProperties);
String webAppName = ctx.getInitParameter("LogFileName");
System.out.println("App log File name " + webAppName);
if (webAppName == null ) {
webAppName = getWebAppName(ctx);
System.out.println("Application name = " + webAppName);
MyRepositorySelector.init(ctx, strLogProperties, webAppName);
LOG = Logger.getLogger(this.getClass());
LOG.info("Log message from Log4jInit ServletContextListener");
System.out.println("\n\n---------------Log4jInit: Complete---------------\n\n");
}

Thanks Matt for your answer.
But I don't finish my testing :)
I tried to deploy the same application on Weblogic 9.2 MP2 and then MP3 (sun jdk domain) and I didn't have problem with generics (application was correctly deployed and running).
Then something was fixed in newer versions or may be bea guys support more then is in EJB 2.x specification.
My next step, I'll try to deploy it on Jrockit domain and I give a note to conference what happen, may be it can help to somebody else.

Problem in Using Log4J with Weblogic 9.2

I am using Weblogic 9.2 and Log4j.
By using Admin console I set the Severity Level to WARNING and inside my java code is given below:
Logger logger = Log4jLoggingHelper.getLog4jServerLogger();
if (logger.isEnabledFor(Priority.DEBUG)){
logger.debug("DEBUG - Test Debug message");
logger.info("DEBUG - Test Info Message");
logger.warn("DEBUG - Test Warning Message");
logger.error("DEBUG - Test Error Message");
logger.fatal("DEBUG - Test Fatal Message");
Somehow the logger.isEnabledFor(Priority.DEBUG) returning 'TRUE' and the follwoing message is displayed.
<Nov 29, 2006 2:44:04 PM EST> <Warning> org.apache.log4j.Category> <000000> <DEBUG - Test Warning Message>
<Nov 29, 2006 2:44:04 PM EST> <Error> <org.apache.log4j.Category> <000000> <DEBUG - Test Error Message>
<Nov 29, 2006 2:44:04 PM EST> <Info> <org.apache.log4j.Category> <000000> <DEBUG - Test Fatal Message>
NOTE - The logger.debug() and logger.info() methods are not invoked because of the severity level to 'WARNING' in the console.
I would like to know why the Somehow the logger.isEnabledFor(Priority.DEBUG) is having a value of 'TRUE'.
I expected only the Somehow the logger.isEnabledFor(Priority.ERROR) will have the value of 'TRUE'.

Did you get an answer to your question? I have the same problem with WebLogic 10.0.

Java Mail/EJB/WebLogic/weblogicSP6 "No Such Provider Exception"

Hi,
My application that is coded to send e-mail is not performing at all.
Application architecture is as follows:
1)JSP-EJB on Web Logic App server and
2)SMTP Host is IIS server and its SMTP service.
3)Using Java Mail API and installed Service Pack 6 of WebLogic that supports Java Mail API
4)EJB Programs coded as per the Sun JavaMail API documentation.
5)Send Mail occuring in the EJB.
Runtime Error: "No such provider exception"
Could u help me by instructing me about:
1)weblogic service pack installation.
2)sample ejb
PS:Same code on a simple java class fired on command line is executing without any exception. Wheras in an EJB on Weblogic is throwing the exception.

That error you are seeing typically comes from JavaMail being unable to
contact the SMTP host. Are you sure that you are a valid user/permitted to
access the mailer?

Using SQLJ in Session EJB (WebLogic 6.1) - connection giving ClassCastError

Hi All
I have one SQLJ file which i have translated to a .java file and , its contents ( methods) have ben pasted in a Session bean , which is deployed in Weblogic 6.1 App Server .
Now in Session bean i am using the jndi lookup of my datasource in Weblogic and creating a conection to the database .
with this connection the normal jdbc methods connects to the databse , but the sqlj method gives a class cast error when i try to allocate the Connection Object to the DefaultContext .
*********************** CODE SNIP ********************
new sqlj.runtime.ref.DefaultContext m_dx = new sqlj.runtime.ref.DefaultContext(conn);
sqlj.runtime.ref.DefaultContext.setDefaultContext(m_dx);
"conn"is the jndi dsn's
DataSourse.getConnection ();
/*In the Method */
sqlj.runtime.ConnectionContext __sJT_connCtx = sqlj.runtime.ref.DefaultContext.getDefaultContext();
the bean compiles , and is deployed sucessfully , and after lookup the conn and m_dx objects are created sucessfully , but when the sqlj method runs it gives a class cast exception .
java.lang.ClassCastException: weblogic.jdbc.rmi.SerialConnection
Is it that Weblogic will not support SQLJ translated code ?
Please help me out , Will i be able to use the Good features of SQLJ in my EJB beans to be Deployed in Weblogic 6.1 Application Server .

Hi,
I am using weblogic 6.1 and oracle 8.1.6, and experiences
problems with connections pools and database crash.
When the database server crashes during an EJB transactions,
the connection used by that transaction seems to be lost and
is never rebuilt when the database server restarts, therefore
the number of connections within the pool shrinks thoroughly
if I have several connections used while the database crashes
or is shutdown for maintenance.
If this db crash takes time to recover, all connections
are destroyed and the pool become unusable.
As soon as all connections have been 'destroyed' I have
the following exception:
'connection pool - none available' when trying to get
a connection.
When I restart the database server, the pool does not rebuilt
itself.
(I am using a test table to test the presence of the database
with a frequency set to 60s)
I did the same operation without EJB transactions and the pool
could rebuilt itself after the database has been restarted.
I had that problem with weblogic 6.0 already and in the
release notes of 6.0_sp2, 2 issues are fixed concerning
the pool fail-over: 044223 and 041793.
I would like to know if these issues are fixed in 6.1 as well,
and if they are related to my problem (Their description is
quite short).
Thank you

Log4J on Weblogic vs Log4J on JBoss

I am working on migrating from JBoss to WebLogic 10. I am able to successfully setup Log4J on WL with a small problem. What I did to configure Log4J was the following.
. Change the Logging implementation from the WL console to use Log4J
. Replace the jboss appenders in the Log4J.xml(org.jboss.appender.DailyRollingFileAppender) to Log4J's DailyRollingFileAppender.
. Added the required Log4J jars to the server classpath
The problem I am having is, WL is logging too much information onto the console and since it is doing that, the same app with similar Log4J's is slower on WebLogic as compared to JBoss.
Is there another setting I need to change to not have WebLogic spit everything out to the console? I compared the thresholds in the JBoss' Log4J vs WL Log4J and everything is the same. Can someone please explain why the difference?
Thanks.

You can add your.properties and log4j.properties to the classpath cant you?
You just need to edit setEnv.cmd (if i remember correctly) in your weblogic server folder to add the folder containing the properties files to the classpath variable.
