Subject [jira] [Created] (OPENJPA-1996) OpenJPA Samples fail on MacOS X
Date Tue, 10 May 2011 19:37:47 GMT
OpenJPA Samples fail on MacOS X
-------------------------------

                 Key: OPENJPA-1996
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1996
             Project: OpenJPA
          Issue Type: Bug
          Components: samples
    Affects Versions: 2.1.0
         Environment: MacOS X 1.6.x
            Reporter: Jody Grassel
            Assignee: Jody Grassel
            Priority: Minor


It was reported on the OpenJPA User Forum that the samples were not working on the MacOS X
architecture.  I downloaded a copy and gave it a ran, and sure enough, it did not work.  Basically,
the problem was in the derby build itself, which attempted to load sun/security/pkcs11/SunPKCS11
and the MacOS X version of the class is apparently different enough from the version Derby
was built against to be incompatible causing the LinkageError that I noted in the derby log:

I was able to resolve the issue by changing the classpath to reference an install of Derby
that is shipped with every install of MacOS X (in /usr/share/derby).  Opening this JIRA issue
to update the OpenJPA samples so that they will choose the version of Derby that comes pre-installed
on MacOS X.
