Unlikely I would like not to use a startup class. Instead I would like to leverage the ability of Logger.getLogger(...) to properly configure log4j according to the file given by the -Dlog4j.configuration system property.

Any solution?

There is no problem to load the log4j.xml or log4j.properties through classload, see my code, the problem is the dtd - not sure what the meaning of dummy://log4j.dtd. And that particular doConfigure is "protected" so I cannot change. A quick solution is to use log4j properties but I still want to know and learn something.

in WebSphere). The WebSphere provides
a StartUp class that is guaranteed to be called by the EJB Container
before it loads the application ear file.

so in my start up class, I tried to load the configuration file (by
providing Url) and I package the log4j.jar file as part of my ear file.
it worked quite well for me

thanks

Subject: dummy://log4j.dtd (log4j problem in Oracle 10gAS)


Hi,


Wonder who has log4j.xml experience in EJB environment?

I tried on Oracle 10gAS on Windows (the iAS version actually is still
9.0.4.2), my log4j initilization code looks like:

InputStream inStream =
Thread.currentThread().getContextClassLoader().getResourceAsStream(sLogF
ileName); new DOMConfigurator().doConfigure(inStream,
LogManager.getLoggerRepository());


There is no problem to load the log4j.xml however the application server
complains the log4j.dtd:

I check DOMConfiguration.java, it contains:

docBuilder.setErrorHandler(new SAXErrorHandler()); docBuilder.setEntityResolver(new Log4jEntityResolver()); // we change the system ID to a valid URI so that Crimson won't
// complain. Indeed, "log4j.dtd" alone is not a valid URI which
// causes Crimson to barf. The Log4jEntityResolver only cares
// about the "log4j.dtd" ending.
inputSource.setSystemId("dummy://log4j.dtd");
Document doc = docBuilder.parse(inputSource); parse(doc.getDocumentElement());


Anybody has an idea and help me, thanks in advance.

Regards
