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.

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 Srini

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:
-------- 04/10/08 18:48:18 Start process -------- 04/10/08 18:48:33 Oracle Application Server Containers for J2EE 10g (9.0.4.0.0) initialized 04/10/08 18:49:09 log4j:ERROR Parsing error on line 0 and column 0 04/10/08 18:49:09 log4j:ERROR File "dummy://log4j.dtd" not found. 04/10/08 18:49:09 log4j:ERROR Could not parse input source [EMAIL PROTECTED] 04/10/08 18:49:09 org.xml.sax.SAXException: Stopping after fatal error: File "dummy://log4j.dtd" not found. 04/10/08 18:49:09 at org.apache.xerces.framework.XMLParser.reportError(XMLParser.java:1245) 04/10/08 18:49:09 at org.apache.xerces.readers.DefaultEntityHandler.startReadingFromDocument( DefaultEntityHandler.java:501) 04/10/08 18:49:09 at org.apache.xerces.framework.XMLParser.parseSomeSetup(XMLParser.java:314) 04/10/08 18:49:09 at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1097) 04/10/08 18:49:09 at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.jav a:195) 04/10/08 18:49:09 at org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:66 5) 04/10/08 18:49:09 at org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:61 6)
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
