Re: Log4j configuration
Thanks Jake, Is there any way to override the configuration or remove the existing appenders. would the call to LogManager.shutdown()and then DOMConfigurator.configure(initUrl) work.

Log4j configuration
Hi, I am adding logging enhancement to my app. There is already a log4j wrapper is available in my app. But the existing is in jar and I can not modify. The problem is, now I have two log4j.xml file. one for my enhancement and other for existing one. I first initialize existing log4j wrapper, it uses DOMConfigurator.configure(initUrl) to configure. After this I call my new APIs, I follow the same DOMConfigurator.configure(initUrl) to override the configuration. The problem here is, I have custom appender, which I specified in log4j.xml of my enhancement, but the custom appender is called twice - once from existing APIs and another from my APIs. I dont know how log4j is invoking my custom appeder, when existing APIs are initialized. I looked this from stack trace. -- View this message in context: http://old.nabble.com/Log4j-configuration-tp29285028p29285028.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
Re: I am trying to add chainsaw support to the eXist XML Database
Hi Scott, I am not familiar with maven, but still I tried to checkout source from repositary and tried mvn install. build is successfull for extras and component. but the build failed for receivers. Is there any other way to get the latest build, other than building it from source myself.

Re: I am trying to add chainsaw support to the eXist XML Database
Hi Scott, Thanks for your quick reply. My application is executable and will be distributed to users, my users also view logs. for example, if a user press "view log" button, I need to open chainsaw. As you said, I can configure in application-wide preferences screen, only after launching the chainsaw. I want to launch it pre-configured, like using command-line parameters when chainsaw main class is launched. Is there a way to send configuration file path as the command-line arguments?

Re: I am trying to add chainsaw support to the eXist XML Database
Hi Scott, For my existing application, we are using log4j and we have log file appender. I want to use chainsaw as the log viewer and need to load the file automatically. How to configure chainsaw to open a file when chainsaw is started.
