I am sure I am missing something.. but I am just not sure what it is...

I am getting

Apr 4, 2007 5:21:07 PM org.apache.commons.digester.Digester startElement 
SEVERE: Begin event threw error                                          
java.lang.NoClassDefFoundError: com.dovetail.jzos.ErrnoException         
 at java.lang.J9VMInternals.verifyImpl(Native Method)

When I go to startup Tomcat.

I am attempting to move from the jzos 1.2.1 to the one that is included with z/OS 1.8 JDK 5.0.

Any help would be greatly appreciated.

Rob,

This looks like you are getting the 1.2.1 version of the shared library (.so) of jzos. Check to make sure you are no longer setting LIBPATH to point to any old jzos libraries. LIBPATH should no longer need to be set as the required .so files are in the SDK.

I keep trying to remove the jzos 1.2.1 from my libpath and classpath, but I am unsuccessful.

Here is my setup...

When I remove the LIBPATH and CLASSPATH with the old JZos, that is when I see the failure.

Right - I forgot about this. Are you using the new version of the Tomcat SAF code? If not, you'll need to update that from our website. See:
