java.lang.Object | +--com.iona.corbautil.ImportExport
This class makes it easy to import and export CORBA object references
via files, the name service or any repository that can be accessed by
command-line utilities. The user calls the importObjRef()
or exportObjRef()
methods with a string containing the
instructions.
Format of export instructions
"name_service#path/within/naming/service"
.
For example, "name_service#foo/bar"
"file#path/to/file"
.
For example, "file#C:\temp\foo.ior"
"exec#command with an IOR placeholder"
.
For example, "exec#cmd /c echo IOR > foo.ior"
Another example, "exec#perl script.pl IOR"
"java_class#full.package.name.of.a.java.class"
.
For example, "java_class#com.iona.corbautil.ImportExportExampleAlgorithm"
Format of import instructions
"name_service#path/within/naming/service"
.
For example, "name_service#foo/bar"
"file#path/to/file"
.
For example, "file#C:\temp\foo.ior"
"exec#command that writes a stringified IOR to standard output"
.
For example, "exec#cmd /c type foo.ior"
Another example, "exec#perl script.pl"
"java_class#full.package.name.of.a.java.class"
.
For example, "java_class#com.iona.corbautil.ImportExportExampleAlgorithm"
Also, any of the URL formats supported by the ORB product are allowed for import (but not for export) instructions. For example:
"IOR:..."
"corbaloc:..."
"corbaname:..."
Error handling
If any errors occur in importObjRef()
or
exportObjRef()
then they throw an
ImportExportException
that contains a descriptive
error message.
Example of using importObjRef()
import com.iona.corbautil.*; import org.omg.CORBA.*; ... class Client { static void main(String[] args) { org.omg.CORBA.Object tmpObj = null; Foo fooObj = null; try { orb = ORB.init(args, null); tmpObj = ImportExport.importObjRef(orb, args[1]); fooObj = FooHelper.narrow(foo); if (fooObj != null) { fooObj.someOp(); } } catch (ImportExportException ex) { System.out.println(ex.getMessage()); } catch (Exception ex) { System.out.println(ex); } orb.destroy(); } }
Example of using exportObjRef()
import com.iona.corbautil.*; import org.omg.CORBA.*; import org.omg.PortableServer.*; ... class Server { static void main(String[] args) { FooImpl fooSv = null; try { orb = ORB.init(args, null); fooSv = ...; // create servant and activate it into a POA ImportExport.exportObjRef(orb, fooSv._this(), args[1]); orb.run(); } catch (ImportExportException ex) { System.out.println(ex.getMessage()); } catch (Exception ex) { System.out.println(ex); } orb.destroy(); } }
