EncodeHintType Error

[Leonardo José]

Hello people,

I need some help.

gerarQrCode(requisicao, idAluno);

public static void gerarQrCode(Requisicao requisicao, String idAluno)

throws WriterException, IOException, NotFoundException {

String qrCodeData = "http://unigranrio.com.br";

// String filePath = "D:\\qrCode\\" + idAluno + ".png";

// String filePath = requisicao.obterRecursoUrl("/" + requisicao.getOrigem().getNomeMantida() + "/img/qrCode/" + idAluno + ".png";

String filePath = Configuracao.getCaminhoImagem() + "qrCode/" + idAluno + ".png";

String charset = "UTF-8"; // or "ISO-8859-1"

// Map<EncodeHintType, ErrorCorrectionLevel> hintMap = new HashMap<EncodeHintType, ErrorCorrectionLevel>();

Map hintMap = new HashMap();

hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);

createQRCode(qrCodeData, filePath, charset, hintMap, 200, 200);

}

public static void createQRCode(String qrCodeData, String filePath, String charset, Map hintMap, int qrCodeheight,

int qrCodewidth) throws WriterException, IOException {

BitMatrix matrix = new MultiFormatWriter().encode(new String(qrCodeData.getBytes(charset), charset),

BarcodeFormat.QR_CODE, qrCodewidth, qrCodeheight, hintMap);

MatrixToImageWriter.writeToFile(matrix, filePath.substring(filePath.lastIndexOf('.') + 1), new File(filePath));

}

I'm using zxing-1.7-javase.jar, zxing-core.jar and also put core-2.0-sources.jar

Here in our work we do not use maven because it is an old project and so we have to go downloading libs and doing the import.

When I run java application it works normally, but when I run it on tomcat it arrives at breakpoint hintMap.put (EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);

Displays the error

Just every time I run via tomcat, I'm getting the following error:

Did you include the zxing*.jar in the .war file? In WEB-INF/lib…

Estou usando esses aqui

zxing-1.7-javase.jar

zxing-core.jar 

core-2.0-sources.jar

see the attachment

Please keep to English.
I'm by no means a native English speaker, but the list is in English.

I can see an excerpt from a screen-shot to what looks like Eclipse IDE.
The question is: do these .jar files exist in the .war that you
deploy in Tomcat.

Or do you start Tomcat from Eclipse? If that is the case, you need
to mark the .jar files for deployment in the project properties
(Deployment Assembly).

BTW. You don't need the -sources.jar on the class path. You also do
not need to add it to the .war. Instead right-click the zxing-core and
the zxing-javase jars, and select the -sources.jar as the source
attachment.

Hello,

So I am starting tomcat locally in my eclipse and I also put both core and javase in my project's build-path and there in the class itself where it doesn't exist, asks to add source ... so I did it all and when I put it to run other than in java application, it presents this error there in the attachment ... saying that java.lang.NoClassDefFoundError: com / google / zxing / EncodeHintType

Since if I give an F3 in this class, it is in the project.

[Leonardo José]

Friend got it ... really needed to put in Assembly

Thank you very much

Yep, it means you didn't actually include the library.

You are also using a very very old version.
