[jira] Created: (HARMONY-1259) NoClassDefFoundError while working
with MX4J loggers
NoClassDefFoundError while working with MX4J loggers
-----------------------------------------------------
Key: HARMONY-1259
URL: http://issues.apache.org/jira/browse/HARMONY-1259
Project: Harmony
Issue Type: Bug
Components: App-Oriented Bug Reports
Reporter: Nellya Udovichenko
Priority: Minor
MX4J has the logging system that allows redirecting the log calls to Commons Logging or Log4J systems and mx4j.jar file is included to the bootclasspath.
However, there are no jar files of Commons Logging (commons-logging.jar) and Log4J (log4j.jar) projects in Harmony bootclasspath.
Therefore, NoClassDefFoundError occurs while using MX4J logging system. This problem appears during Geronimo launching with Harmony.
Below is the localized test case for easy bug reproducing:
-----------------------------------------------------------------------------------------------------------------------------------------------------
import java.lang.reflect.Method;
import java.util.ArrayList;
import javax.management.MBeanServer;
import javax.management.MBeanServerFactory;
public class MX4JLoggerTest {
public static void main(String[] args) {
try {
Class cl = Class.forName("mx4j.log.Log");
Class clParam = Class.forName("mx4j.log.Logger");
Method method = cl.getDeclaredMethod("redirectTo", new Class[] {clParam});
clParam = Class.forName("mx4j.log.CommonsLogger");
method.invoke(null, new Object[] {clParam.newInstance()});
} catch (ClassNotFoundException e) {
System.out.println("MX4J classes aren't found in JDK");
} catch (Exception e) {
System.out.println("Exception: it can't force MX4J to use commons.logging classes");
}
try {
ArrayList servers = MBeanServerFactory.findMBeanServer("test");
System.out.println("PASSED");
} catch (NoClassDefFoundError e) {
System.out.println("FAILED with exception:");
e.printStackTrace();
} catch (Exception e) {
System.out.println("PASSED with exception");
}
}
}
-------------------------------------------------------------------------------------------------------------------------------------------------------
Test output.
Harmony with commons-logging.jar added to classpath (not bootclasspath):
C:\>java -cp C:\commons-logger.jar; MX4JLoggerTest

Geir Magnusson Jr commented on HARMONY-1259:
--------------------------------------------
The solution isn't to include CLOGGING or Log4J in the boot classpath. Geronimo should include all necessary jars, so I believe we have some issue releated to classloading in DRLVM

[jira] Commented: (HARMONY-1259) NoClassDefFoundError while working
with MX4J loggers
Posted by "Mikhail Markov (JIRA)" <ji...@apache.org>.

Mikhail Markov commented on HARMONY-1259:
-----------------------------------------
Geronimo has all necessary jars but does not include commons-logging.jar to the bootclasspath.
I've downloaded mx4j.jar + commons-logging.jar and tried to run MX4JLoggerTest.java on RI:
If i run it on RI with the command (on Windows XP):
"java -Xbootclasspath/p:mx4j.jar -classpath commons-logging.jar\;. MX4JLoggerTest"
to force RI to use MX4J implementation of JMX then i got the following result:
FAILED with exception:
java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at mx4j.log.CommonsLogger.setCategory(CommonsLogger.java:27)
at mx4j.log.Log.createLogger(Log.java:211)
at mx4j.log.Log.getLogger(Log.java:180)
at javax.management.MBeanServerFactory.getLogger(MBeanServerFactory.java:34)
at javax.management.MBeanServerFactory.findMBeanServer(MBeanServerFactory.java:105)
at MX4JLoggerTest.main(MX4JLoggerTest.java:24)
BUT if i run it on RI with the command
"java -Xbootclasspath/p:mx4j.jar\;commons-logging.jar MX4JLoggerTest"
then the test passed:
PASSED with exception
So, it seems that the problem is indeed in MX4J implementation.
