Weblogic Update to Opatch 13.1 results in NoClassDefFoundError

Hello,

An attempt to install a patch for Weblogic 12.1.2.0.0 pointed to update my Opatch to 13.1.0.0.0. I downloaded it from Oracle Support, patch 6880880 (the one having release 13.1.0.0.0 - p6880880_131000_Generic.zip), and followed the steps from the readme file. When testing it from the command line with 'opatch' instruction, i get:

Exception in thread "main" java.lang.NoClassDefFoundError: com/oracle/cie/gdr/external/InventoryException
at oracle.opatch.OPatch.main(OPatch.java:548)
Caused by: java.lang.ClassNotFoundException: com.oracle.cie.gdr.external.InventoryException
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
... 1 more

Has anyone encountered this, or does anyone have an idea about how to fix this? I'm fairly new to Weblogic, and I would appreciate any guidance.

Thank you!

Problem was solved after installing latest Weblogic with Weblogic installer, and not unpacking it from Oracle's provided zip archive.
 
It is sorta covered in the JavaRanch Style Guide.
