Hi, so there exists somewhere a log4j.dtd, which describes the configuration file, is it correct? If yes, where can I find the DTD?

If you were to write a schema for the existing configuration format, you would need to write one XSD file for the "http://jakarta.apache.org/log4j/" namespace which contains the configuration element and a non-namespace qualified schema for all the other elements. If you did that, it would give you the XML equivalent of a weakly typed language, it would only detect gross structural errors. It wouldn't be an improvement over the log4j.dtd which is the appropriate validation technology for XML documents that aren't namespace aware. There was an attempt to define a new configuration file format that was documented and strongly typed, however that effort stalled for lack of participation. If and when log4j 2.0 development starts, the likely approach would be to replace the existing configuration code with some configuration project and support the existing formats with transforms to the new format. > Thanks for your help and kind regards, > Andreas > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
