[dev] Exception on trying to set an rdf metadata in java

[Andrea Chiumenti]

Hello I'm having this problem

try
                {
                    XMultiServiceFactory xDocFactory =
(XMultiServiceFactory)UnoRuntime.queryInterface(XMultiServiceFactory.class,
xDoc);
                    Object xMetafield =
xDocFactory.createInstance("com.sun.star.text.textfield.MetadataField");
                    XText xMetafieldText =
(XText)UnoRuntime.queryInterface(XText.class, xMetafield);
                    xMetafieldText.setString(""); // clear the field: delete
all content  <--------------------------- LINE 110
                    XTextCursor xCursor = xMetafieldText.createTextCursor();
                    xMetafieldText.insertString(xCursor, "evviva", true);


                }
                catch (java.lang.Exception e)
                {
                    e.printStackTrace();
                }

What is it ? and is it correct that I'm not able to resolve
com.sun.star.text.textfield.MetadataField from java ?
