JAXB XML Marshalling Object Only, but Unmarshalling Requires Full Structure? -

i using standard jaxb api work xml. need marshal , un-marshal object (so result should same object). first marshal string, , opposite -- unmarshal string object.

the problem marshaller.marshal(obj,os) giving me child only (enclosed in xml). when seek unmarshal back, errors missing parent tags expected.

e.g. (1) marshalled string object "fieldset":

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <field1>field1</field1> <field2>field2</field2>

(2) effort unmarshal xml string "fieldset" object:

javax.xml.bind.unmarshalexception: tag name "field1" not allowed. possible tag names are: - linked exception: [com.sun.msv.verifier.validityviolation: tag name "field1" not allowed. possible tag names are: "parent"]

in schema, "parent" top-level element should precede "fieldset".

why these standard jaxb operations not symmetrical, , need synchronize them , avoid child-only/missing parent issue? thanks.

to supply root element info can 1 of following:

1 - annotate class annotating @xmlrootelement

@xmlrootelement public class fieldset { }

2 - wrap object marshalling instance of jaxbelement

qname qname = new qname("root"); jaxbelement<fieldset> jaxbelement = new jaxbelement<fieldset>(qname, fieldset.class, fieldset);

xml jaxb marshalling

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
