APAR status
Closed as program error.

Error description
When configuring a shared library, the native library paths are
not being picked up and added to the classloader, which could
lead to native libraries not being found.
.
Symptom of this problem is to see the following
'UnsatisfiedLinkError' in the WebSphere z/OS servant region.
The following example was issued when the server was starting
up, and the application is starting:

Local fix
Define the 'Native Library Path' in the
'Classpath' box during the Shared Library definition.
.
 Environment -> Shared Libraries -> shared_library_name ->
 Classpath(entered here)
 .
 rather than in the
 Environment > Shared Libraries > shared_library_name.
 Native Library Path (NOT entered here)
.
 The Native Library Path that is entered in the 'Classpath'
 should be 'just the path', and should not include the actual
 file name.

java.lang.UnsatisfiedLinkError may occur when using shared
libraries if a shared library was defined via the Administration
Console and the native library path was supplied via the native
library path field on the Shared Library definition panel
instead of the classpath field. Prior to this PTF the native
library path field on shared libraries is not read when a
server level classloader is defined using the shared library or
the shared library is added to an application.

java.lang.NoClassDefFoundError will occur when using shared
libraries if a shared library was defined via the Administration
Console and only the path to the jar and zip files was specified
in the classpath field. Prior to this PTF the Shared Library
classpath was not searched for all the jar and zip files.
Problem conclusion
WebSphere runtime code was updated to read the native library
field supplied for the shared library and return it when it is
used to define a server level classloader or when the shared
library is added to an application. WebSphere runtime was
also updated to add all jar and zip files to the classpath
supplied on a Shared Library definition.
