log4j - No grammar available for namespace
JDeveloper11g
I'm getting an informational warning for the log4j.xml file.
The warning is:
No grammar available for namespace http://jakarta.apache.org/log4j/, contents of element configuration cannot be validated
The start of the log4j.xml file looks like this:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
The contents of the log4j.xml file are correct.
The org.apache.log4j stuff is available in the project.
How can I tell the JDeveloper environment where to find the log4j.dtd or whatever it needs?
Everything runs just fine.
For now I'm just ignoring the informational warning.
A better solution will be to tell the JDeveloper environment whatever it needs in order to remove the warning.
Any ideas?
thanks.
