RE: how to output to different files with different information

Thanx a lot. How to Config the com.mydoain.database, In the log4j.properties files, I use com.mydomain.database, it gives the information of : log4j:ERROR Could not find value for key or log4j.logger.com.mydoain.database = INFO A2 log4j:ERROR Could not instantiate appender named " com.mydoain.da

Re: how to output to different files with different information

You should really consider switching to Logger. All the old classes (Category being one of them) have been deprecated (although only unofficially, as they are not marked as such in javadocs) and are scheduled to be removed sometime later this year. That being said, the syntax using the Category c

Re: Do people use log4j in J2EE applications?

thanks for the clarification. I have always erred on the side of not creating a connection that needs to be managed during bean passivation i.e., the container should be providing this management thru a JCA/etc... At 06:52 AM 3/11/2003 -0800, Nicholas wrote: The spec is quite specific on t

RE: What is the trend in the Java community?

Hi Andreas, One factor you should certainly take into consideration is whether your deployment environment is guaranteed to be JDK1.4 or higher. For example, many J2EE servers still only support JDK 1.3.x so the logging APIs are unavailable. Hope this helps Keith -Original Message- Fr

Hi Andreas, Check out the wiki page on this topic at: http://nagoya.apache.org/wiki/apachewiki.cgi?Log4JProjectPages/Log4jvsJDKLogging Just hang around this user list and the log4j developer list a while, and I think you'll see enough exciting things going on to keep you wishing you were using

RE: What is the trend in the Java community?

Howdy, It's kind of tough to take a guess at the whole java community, as it's too huge. But among the mailing lists and communities I belong too, there actually is a trend: novice developers use JDK 1.4. Better developers use log4j. This happens because better/more experienced developers appre

What is the trend in the Java community?

Hi, We are currently starting Java development within our company. I am confused as to whether we should use log4j or if we should consider using the new logging API in JDK 1.4... What factors should I take into consideration, and what is the Java community doing? Regards, Andreas

Re: Do people use log4j in J2EE applications?

The spec is quite specific on that note. You can act as a socket client, but not a socket server: 24.1.2 Programming restrictions . . • An enterprise bean must not attempt to listen on a socket, accept connections on a socket, or use a socket for multicast. The EJB architecture allows an enterpris

RE: Do people use log4j in J2EE applications?

Nicholas is exactly correct. The spirit of the restriction is to restrict file access from within the beans for the purpose of storing/retreiving "business data". Business data being, for example, the state of an Entity EJB. The reasoning is that filesystems do not support transactional processi

Re: Do people use log4j in J2EE applications?

Hi Michael, Yes! I use log4j inside EJB containers all the time. You are correct about the EJB specs ... in fact you should not open a Socket directly either.. if you wanted to go this route you would need to make the Sockets obtainable from the container by implementing a construct in the J

It is not that black and white. The EJB specification does not prohibit you from writing to a file. EJB Spec 2.0 24.1.2 Programming restrictions . . • An enterprise bean must not use the java.io package to attempt to access files and directories in the file system. The file system APIs are not we

Do people use log4j in J2EE applications?

Hi folks, Just a quick query, as the EJB specification forbids you to write to a file (which is what i want to do!) why is it incorrect to do so? The alternatives are using SocketAppender and JMSApender but how do you write to a file using these? or put another way... can you? Cheers, _

Re: how to output to different files with different information

Can you include your log4j.properties file? Strictly based on the names of the files, it seems you want certain log messages to go to A1 and all others to go to A2; then irregardless of whether a message went to A1 or A2, also log it to A3. That correct? In general that would be setup as: log4j
