>From the source code for StandardContext.java, line 4141 is: 

  TldConfig tldConfig = new TldConfig();

What I don't understand is how there can be a NoClassDefFoundError for
TldConfig when: 

1. TldConfig is clearly imported in line 85: 
  import org.apache.catalina.startup.TldConfig;

2. TldConfig.class resides in the same .jar as StandardContext.class
(catalina.jar)

It seems to me that there should be no NoClassDefFoundError because
StandardContext would not even be able to compile without TldConfig. 

Is there a problem with the classloader? Is my configuration completely
wrong? Can anyone shed some light on this? Any help would be most
appreciated. 

Thanks,
August
