PI25045: USED CICS OSGI BUNDLE TO EXPORT DATA/CFG FILES BUT YOU CAN'T GET THE ACCESS TO CONFIG FILES TO WORK PROPERLY.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This problem is caused by the classloader in effect which
  means that the config or data files cannot be seen.  This was
  never a problem with pooled JVM because everything could be
  loaded from the classpath.
  
  What the application needs to do is to switch the current
  threads ContextClassLoader to the Equinox ContextFinder
  classloader, load the file using
  classLoader.getResourceAsStream(); and then switch the
  ContextClassLoader back to what it was originally.
  .
  Development have come up with a CICS change which automatically
  sets the correct class loader so the switching around would not
  have to be done by the application.

  ****************************************************************
  A Java application runs in a JVM server. The application
  contains the code to read in some configuration data from a
  file within the same OSGi bundle. This file is loaded using
  the ClassLoader.getResourceAsStream method call. CICS loads
  the file using the context class loader of the current thread.
  The load fails to locate the file, and getResourceAsStream
  returns a null pointer.
  
  If the application attempts to use the pointer returned from
  getResourceAsStream then exceptions such as NullPointerException
  or FileNotFoundException may occur, and the transaction will

Problem conclusion

• The CICS OSGi environment has been changed to modify the
  current context class loader to be an Equinox ContextFinder
  class loader. This allows the application to load resources
  from within the current OSGi bundle
  using ClassLoader.getResourceAsStream().
