Yes, but this does not reveal what the reason is. Maybe you could test,
whether all external methods can be successfully loaded in "Apache.cls"
. To do so you could try to run the following program to test. It will
list all external methods as found in "Apache.cls" and whether it is
possible to load them as external methods into ooRexx (in the output
sucess=1=.true, failure=0=.false):

    /* ---rgf, 2010-02-17, test availability of external mod_ooRexx-methods */

       externalMethodArray~append("LIBRARY mod_oorexx WWWCnxRecAborted")

       say "testloading external methods:"
       do descriptor over externalMethodArray~sortWith(.CaselessComparator~new)
          parse var descriptor . . externalEntryName '"'
          say "  " pp(externalEntryName) testExternalMethodLoading(descriptor)
       end

    ::routine testExternalMethodLoading
      parse arg descriptor
      return .method~loadExternalMethod("testMethod", descriptor)<>.nil


    ::routine pp      -- "pretty-print"
      parse arg value
      return ("[" || value || "] ")~left(30, ".")
      

If you run the above program all loaded external methods should show
"1", if they all could be loaded.
