Invalid byte 2 of 2-byte UTF-8 sequence: XML saved as String varible

I get the following error due to Latin text in my XML.
Invalid byte 2 of 2-byte UTF-8 sequence: XML saved as String varible
My XML is written to a String variable (I don't import a file).
I tried to set encoding to "UTF-8", but I might have done it wrong.
Can you help please?
My code:
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
InputStream inputStream = new ByteArrayInputStream(GET_XML.getBytes());
Document doc = dBuilder.parse(inputStream);
doc.getDocumentElement().normalize();

You are seeing this error, because you are feeding xml containing ISO-8859-1 (aka Latin-1) characters without proper XML declaration:
<?xml version='1.0' encoding='ISO-8859-1' standalone='no' ?>
You have two options either correct it by sourcing xml with above declaration.
OR forcing UTF-8 during byte conversion.
new ByteArrayInputStream(GET_XML.getBytes(StandardCharsets.UTF_8));

Parsing xml file error

I'm trying to transform an XML file into a document like this:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse("C:/xml/41111208890622000144550010000000011000003066-nfe.xml");
Document document = db.parse(new InputSource(new StringReader("C:/xml/41111208890622000144550010000000011000003066-nfe.xml")));
but it is giving the error message:
Exception in thread "main" org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1;
someone knows what to do?

You're currently creating a reader containing the string
"C:/xml/41111208890622000144550010000000011000003066-nfe.xml"
and asking the DocumentBuilder to parse that as if it were XML, when it's clearly not. (I'm referring to the second parse call, which I suspect is the one in your actual code. The code you've provided wouldn't compile as you've declared document twice.)
You can create a FileInputStream or perhaps an InputStreamReader wrapped around it:
String filename = "C:/xml/41111208890622000144550010000000011000003066-nfe.xml";
try (FileInputStream input = new FileInputStream(filename))
{
Document document = db.parse(new InputSource(input));
}
(I prefer to use a stream directly, and let the parser detect the encoding.)
Now this call:
Document document = db.parse("C:/xml/...");
would nearly work and may actually work, using DocumentBuilder.parse(String) - it depends on whether parse is happy to handle a filename as a URI. (I've seen some XML APIs that are fine with that, and some that aren't.) If it doesn't work, try using the file:// scheme:
Document document = db.parse("file://C:/xml/...");

Java XML UTF-8 inconsistency

I have a problem converting a UTF-8 document correctly into HTML.
When the code is run inside a glassfish server on Solaris, it produces invalid results.
When run on my test environment on Windows, the results are valid.
Both environments are using Java 1.6.0_27
I am including the code for both - I don't see any relevant difference.
The output from the app server test is below (if the UTF-8 goes through this process):
<CityName>Ð Ð¾Ð²Ð¾Ñ Ð¸Ð±Ð¸Ñ€Ñ Ðº</CityName>
<CityName>Новосибирск</CityName>
Note that the second has several entity encodings, whereas the first is pure UTF-8. The encodings are wrong.
First - the app server code (logger is a log4j Logger - it shows good results on test13, bad on test14):
logger.info("===test13:"+descr+req);
DocumentBuilderFactory domFactory = DocumentBuilderFactory .newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document doc = domBuilder.parse(new InputSource(new StringReader(req)));
logger.info("===test14:"+XmlHelper.domToString(doc));
Then, the test code - "out" shows good data in both cases:
PrintStream out = new PrintStream(System.out, true, "UTF-8");
String inmsg = TestRvcMessage.readUtfFile(fname);
inmsg = inmsg.trim();
out.println("INPUT:"+inmsg);
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document doc = domBuilder.parse(new InputSource(new StringReader(inmsg)));
out.println("OUTPUT:"+xmlHelper.domToString(doc);

Parse a single Line of XML into a HashMap

I'm building an android app that communicates to a web server and am struggling with the following scenario:
Given ONE line of XML in a String eg:
"<test one="1" two="2" />"
I would like to extract the values into a HashMap so that:
map.get("one") = "1"
map.get("two") = "2"
I already can do this with a full XML document using the SAX Parser, this complains when i try to just give it the above string with a MalformedUrlException: Protocol not found
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
Document doc = null;
builder = factory.newDocumentBuilder();
doc = builder.parse("<test one="1" two="2" />"); //here
I realize some regex could do this but Id really rather do it properly.
The same behaviour can be found at http://metacpan.org/pod/XML::Simple#XMLin which is what the web server uses.
Can anyone help? Thanks :D

DocumentBuilder.parse(String) treats the string as a URL. Try this instead:
Document doc = builder.parse(new InputSource(new StringReader(text)));
(where text contains the XML, of course).

Parsing xml response

I have a JAVA application where I am sending some xml requests and receiving xml responses. I first receive response in string and then write a file and storing this file into file system. Then while parsing the xml response file I am accessing this from file system and use some of the data for further business logic.
File file = new File("log\\XMLMessage\\LastXMLResponse.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);
Now I am thinking to distribute this JAVA application via Java Web Start (JWS) application and as I know I cannot keep this file into jar file since there will be modification in this file on regular basis.
What do you suggest me to do? Can I parse the String directly (no need to store the response into file)?
Document doc = db.parse(xmlMessage);
or where can I keep this file? I don't want to show this file to the user of my application.

Take the String, make a StringReader from String, make a InputSource from StringReader, then call parse on your DocumentBuilder.

Yes, you can parse the string directly,no need to store it in a file.
Try this:
String xml = "<xml></xml>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new ByteArrayInputStream(xml.getBytes()));
System.out.println(doc);
