java - Explanation of JAXB error: Invalid byte 1 of 1-byte UTF-8 sequence -

-

We are parsing an XML document using JAXB and get this error: 

  [org .xml.sax.SAXParseException :. Invalid byte of 1-byte UTF-8 sequence 1] javax.xml.bind.helpers.AbstractUnmarshallerImpl.createUnmarshalException at (AbstractUnmarshallerImpl.java:315)

What exactly does and how do we Can this solve ??

We are implementing the code as: 

  jaxbContext = JAXBContext.newInstance (Results.class); Unmarshaller unmarshaller = jaxbContext.createUnmarshaller (); Unmarshaller.setSchema (getSchema ()); Result = (results) unmarshaller.unmarshal (new FileInputStream (inputFile)); The problem appears due to this "strange" character in the XML file:  ¿

update

/ code>

Why is such a problem caused ??

Update 2

There are two odd letters in the file. They are in the middle of the file, note that the file is built on the basis of the data in the database and those weird characters get in the database in any way.

Update 3

Here is the full XML snippet: 

  & lt; Details & gt; & Lt ;! [CDATA [Mt. Belvieu ¿Texas]] & gt; & Lt; / Details & gt;

Update 4

Note that someone & lt ;? Xml ...? & Gt; is not a header.

Hex BF

For the special character, then your problem is that JAXB behaves without XML files and & lt ;? Xml ... & gt; UTF-8, when your file uses some other encoding (probably ISO-8859-1 or Windows-1252, if the header 0xBF character actually means ¿).

You can change the file's creator, you can add & lt ;? Xml ... & gt; Write a file using the header with the actual encoding specification, or just use UTF-8 for the bus.

If you can not change the manufacturer, then you have to use InputStreamReader with a clear coding specification, because (unfortunately) JAXB does not allow to change its default Is encoding: 

  result = (results) unmarshaller.unmarshal (new InputStreamReader (new FileInputStream (inputfile), "ISO-8859-1");

However, this solution is delicate - it fails on input files with & lt;?. Xml ... & gt; Header with different encoding specification

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
