RE: Default configuration not seeing my appender
Howdy, Personally, I've encountered nothing but grief when attempting to work with windows-style file paths. (Or more general resource paths, e.g. for JNDI). I don't know if this is a shortcoming of java the language, the File/URI/URL class implementations, the windows file system, or what else, but I don't care. Save yourself time and hassle and work exclusively with unix style paths.

Re: Default configuration not seeing my appender
You really don't have to worry about it. Ant understands both and Java understands mixed use of / and \ when using file:///. BTW, you can also do relative paths like this and it will work for both UNIX and Windows... file:../WEB-INF/log4j.xml Jake At 11:14 AM 3/28/2003 -0500, you wrote: Shapira, Yoav wrote: Howdy, Personally, I've encountered nothing but grief when attempting to work with windows-style file paths.

Save yourself time and hassle and work exclusively with unix style paths. Yoav, Thanks for your thoughts. I am kind of new to using File I/O on Windows with Java because formerly my only deployment was to a Linux box. I am running Cygwin on Windows, but I believe that only provides me with the convenience of Unix-style file paths in a shell. Do you know of a way that I can force Ant to use Unix-style file paths even though it is technically a Windows machine? Perhaps I should ask on ant-user. At least in my Java code I can use Unix/Java-style file paths. Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Another Default configuration not seeing my appender Question
In the same directory as the build.xml (ant) and gui.xml (jelly) files I'm working with (thats why I'm trying to keep it relative). I've tried using the classpath to add the log4j.xml file but Ant's java task screams: [java] CLASSPATH component C:\eclipse\workspace\project\log4j.xml: java.util.zip.ZipException: error in opening zip file But, I'm sure thats an issue that should be taken up on thier lists or Sun. -Mark Ceki Gülcü wrote: Hi Mark, Where is the log4j.xml file located?
