How to use log4j in OC4j

Can you give me a sample log4j.xml used for oc4j (orcle 9iAS ). Also
I want to read a env. variable to read the oc4j home in that xml to redirect the log msgs to that folder.Any clue on that ?
(I am developing windows env & deploying solaris. So I cannot use C:\oc4j\.... in my log4j.xml . I need to read the oc4j home from env variable)

This is mine. You cannot read environment variables in the DB JVM using System.getProperty(). One solution may be to configure log properties dynamically using PropertyConfigurator.configure().
log4j.rootLogger=DEBUG, logfile
# Log file appender configuration
log4j.appender.logfile.File=batch.log
log4j.appender.logfile=org.apache.log4j.FileAppender
log4j.appender.logfile.layout=org.apache.log4j.xml.XMLLayout

Chris

How to use the same OC4j server with different port number

How to use the same OC4j server with different port numbers..?
I have to OC4J installed on my machine on different hard disk drives....
I want to be able to run both the server simultaneously..?
is it possible ..it yes then how..?
for that i have changed the port number of one server...
but when i am trying to start the other server with different port number..it says that JVM -Bind already...
Is there any clues...?
Nilesh G

In the config directory:
default-web-site.xml: Change the port the HTTP listener listens on
jms.xml: Change the port the JMS service listens on
rmi.xml: Change the port the ORMI listener listens on.
Or, you can add another web-site.xml file, and deploy your applications to 1 server, and bind the web applications to the different web sites. This way you only have to deploy your applications to 1 place.

How to use JMX with oc4j

is there any document about how to use JMX with OC4J? the intention is that I would like to create an application, using JMX to manage OC4J, such dynamiclly adding connection pool, create data source. potentially, restart server, application ...
is there any document about this?
Thanks

In addition to that, the documentation also has a section on accessing OC4J JMX/MBeans:
http://otndnld.oracle.co.jp/document/products/as10g/101300/B25221_03/web.1013/b14433/mbeans.htm#sthref163
The blog below also has examples, albeit from a Groovy perspective, but nonetheless, examples of how it can be done easily translated into Java:

How to use log4j logging

Hi all,
i'm very new to the world of software devlopment.I'm currently working on devloping banking application in JAVA.
I wanted to log all the exceptions thrown by the code.

Thanks

You should find what you need on the Log4j Project Page.

How to use log4j into weblogic 10.3

Hi,
I am migrating an enterprise application from JBoss 4.3 + JBossCache to WebLogic 10.3+Coherence.
I am blocked since I can't get log4j to work inside WL.
I enabled log4j inside the administration console, as stated in the user guide.
Googling I've also found that I have to copy these 2 jars
wllog4j.jar
llog4j-1.2.14.jar
inside my domain lib directory (that is C:\Oracle\Middleware\user_projects\domains\base_domain\lib), and I did it.
Now where should I put the log4j.xml configuration file and how can I tell to WL to use that xml as log4j configuration ?
To give you more information, my classes use log4j in this way:
Logger log = Logger.getLogger(MyClass.class);
And I am constantly getting this error:
log4j:WARN No appenders could be found for logger (it.ltm.ejba.session.EjbAServiceBean).
log4j:WARN Please initialize the log4j system properly.
I hope someone can help me.
I apologize for this stupid question, but really I didn't find a good guide/tutorial on the net.
Thanks in advance.

Hi Jay, thanks for helping me.
In fact what I am trying to do is a server-wide log4j configuration.
Your solution implies writing-deploying-maintaining 1 log4j configuration file for each application developed inside the application server.
This is not what I want to do.
Digging around WL 10.3 installation folders, I've found a log4j.properties file inside the medrec example application (C:\Oracle\Middleware\wlserver_10.3\samples\domains\medrec).
It uses this properties file setting a startup parameter to the server (file setDomainEnv.cmd):
set JAVA_PROPERTIES=%JAVA_PROPERTIES% -Dlog4j.configuration=file:%LOG4J_CONFIG_FILE%
I would like to do the same starting the server from eclipse 3.5.
I am working on this, I hope you can give some hints.
Thanks a lot

Thank you!

"I have included the log4j.jar in libraries" -> what does that actually mean? What steps did you take and where?
Because one thing is for certain: the jar is not deployed to the proper location so it is on the application's classpath or else you wouldn't be running into this issue.

Using log4j in jdk1.4

Hi,
I'm Babu. I am wanting to know about the how to of using log4j in jdk 1.4.
Babu.

Do you have a question specifically about how to use log4j in jdk 1.4? There's nothing different when using log4j with jdk 1.4 than with other versions. Put log4j.jar in your classpath. Read the log4j documentation.

Using log4j in EJB: where to configure the logging service?

Hi there,
I have a question on how to use log4j in EJBs. Details:
I want to provide a static final Logger instance in each bean class. This logger will be used by my bean instance to log some interesting messages. The log4j service should be initialized (by calling BasicConfigurator.configure() for example) only once before any message is logged. So where should i place the initialization code?
I know that for a web app, i can define a ServletContextListener implementation to do the initialization work when my web app is loaded. Is there anything similar for EJB?
Thanks in advance.
heavyz

Hi xHacher,
do you mean something like this?
public class LogFactory {
    static {
        BasicConfigurator.configure();
    public static Logger getLogger(Class clazz) {
        return Logger.getLogger(clazz);
}And in each of my bean class, i may get the logger by using:
private static final Logger log = LogFactory.getLogger(MyBean.class);The code above ensures that log4j is well initialized before any logger instance is created. But any better solutions?

How to Starting and Stopping OC4J Server using Ant

How to Starting and Stopping OC4J Server using Ant
In the ant task definitions for ant-oracle-classes.jar (see antlib.xml) there are two tasks called
     name="restartServer" classname="oracle.ant.taskdefs.deploy.JSR88StartServer"
     name="shutdownServer" classname="oracle.ant.taskdefs.deploy.JSR88ShutdownServer"
I thought that these would shutdown and start the OC4J server. I guessed the parameters as – (Does anyone know where 50 ant targets are documented?)
<oracle:restartServer
userid="${oc4j.admin.user}"
     password="${oc4j.admin.password}"
     deployeruri="${deployer.uri}"
/>
<oracle:shutdownServer
     userid="${oc4j.admin.user}"
     password="${oc4j.admin.password}"
     deployeruri="${deployer.uri}"
/>
This, however does not start and stop the SOA suite. To do that I've hacked this solution together -
<path id="oc4j.console">
     <pathelement location="${oracle.home}/config"/>
     <pathelement location="${oracle.home}/jlib/startupconsole.jar"/>
     <pathelement location="${oracle.home}/opmn/lib/optic.jar"/>
     <pathelement location="${oracle.home}/lib/xmlparserv2.jar"/>
</path>
<target name="stop" description="stop oc4j server" depends="init">
     <java classname="oracle.appserver.startupconsole.view.Runner">
          <classpath refid="oc4j.console"/>
          <sysproperty key="ORACLE_HOME" path="${oracle.home}"/>
          <arg value="stop"/>
     </java>
</target>
<target name="start" description="restart oc4j server" depends="init">
     <java classname="oracle.appserver.startupconsole.view.Runner">
          <classpath refid="oc4j.console"/>
          <sysproperty key="ORACLE_HOME" path="${oracle.home}"/>
          <arg value="start"/>
     </java>
</target>
This sort of works – except when the SOA suite doesn't stop cleanly – and needs user interaction to press a Close button. This isn't very useful when doing a continous integration build and deploy.
So, does anyone have any suggestions or alternative methods to do this?
- frank

Actually if the server throws exceptions when it stops (which it always has since we applied patch 10.1.3.3) this technique will pause until a user responds to pop-up ... So a better way (I think) is -
<target name="start" description="start oc4j server" depends="init">
<java classname="oracle.appserver.startupconsole.view.Runner">
<classpath refid="oc4j.console"/>
<sysproperty key="ORACLE_HOME" path="${oracle.home}"/>
<arg value="start"/>
</java>
</target>
<target name="stop" description="stop oc4j server" depends="init">
<echo message="We expect OC4J *NOT* to stop cleanly, so we will timeout after 3 minutes ..."/>
<java classname="oracle.appserver.startupconsole.view.Runner" fork="true" timeout="180000">
<classpath refid="oc4j.console"/>
<sysproperty key="ORACLE_HOME" path="${oracle.home}"/>
<arg value="stop"/>
</java>
</target>
<target name="restart" description="restart oc4j server">
<antcall target="stop"/>

<waitfor maxwait="2" maxwaitunit="minute">
<not><http url="http://${oc4j.http.hostname}:${oc4j.http.port}"/></not>
</waitfor>
<antcall target="start"/>
</target>
