When I start my tomcat server with our application, I get the following
errors and the tomcat fails to startup:

SEVERE: End event threw exception
org.apache.commons.logging.LogConfigurationException: User-specified log
class 'com.sun.idm.logging.trace.TraceLogger' cannot be found or is not
useable.

I googled around and found that the TraceLogger class must have a
constructor with a single String parameter. So I checked for that:

C:\Documents and Settings\akumar\Desktop\Downloads>javap
com.sun.idm.logging.trace.TraceLogger
Compiled from "TraceLogger.java"
public class com.sun.idm.logging.trace.TraceLogger extends
java.lang.Objectimplements
org.apache.commons.logging.Log{
  public static final java.lang.String code_id;
  public com.sun.idm.logging.trace.TraceLogger(java.lang.String);
  public boolean isTraceEnabled();
  public boolean isDebugEnabled();
  public boolean isInfoEnabled();
  public boolean isWarnEnabled();
  public boolean isErrorEnabled();
  public boolean isFatalEnabled();
  public void trace(java.lang.Object);
  public void trace(java.lang.Object, java.lang.Throwable);
  public void debug(java.lang.Object);
  public void debug(java.lang.Object, java.lang.Throwable);
  public void info(java.lang.Object);
  public void info(java.lang.Object, java.lang.Throwable);
  public void warn(java.lang.Object);
  public void warn(java.lang.Object, java.lang.Throwable);
  public void error(java.lang.Object);
  public void error(java.lang.Object, java.lang.Throwable);
  public void fatal(java.lang.Object);
  public void fatal(java.lang.Object, java.lang.Throwable);
  static {};
}


And it is there: A constructor with a single String argument. But I still
get the above errors. Can someone help me please.
